cctv42.co.uk - using cat5 cable and baluns to connect a cctv camera to your DVR

[@outbackeddie]

FINALLY, I see how to do this after reviewing about a half dozen other videos. Your explanation of the process was clear and well done. Thank you. Thank you. Thank you.

[@cctv42]

Glad you found it useful

[@cctv42]

Hi there. There are 4 pairs of wires. For example, our CAT5e cable has: Blue+Blue/White Green+Green/White Brown+Brown/White Orange+Orange/White Pick a colour (we always use blue) and separate those 2 wires from the remaining pairs. Use these for the video. Use the solid blue in the +ve on the balun AT BOTH ENDS. The blue/white is the same, but -ve. Split the remaining 3 pairs and use all solid colours for +ve (at both ends) and all stripy colours for -ve (at both ends). Hope that helps! :o)

[@haydnthomasfilmscorporate1553]

Is there a specific reason why you only double up on the power side and not video?

[@cctv42]

The problem quoting maximum distances is that it depends on the current draw of the camera. It all comes down to the cross sectional area of the conductor. More copper equals more distance. In practice there probably won't be a vast difference in distance. On the video side however the Cat5 / balun combination is superb. 300 metres is huge. You can even extend that to 1200 metres by using active baluns. Finally the termination is very easy, no crimping tools just a small screwdriver.

[@cctv42]

Your English is certainly better than my Mexican! That is the way we always connect it up - solid colour is positive, stripe (white and thin colour line) for negative to avoid confusion, however it doesn't really matter as long as you keep it exactly the same throughout the whole system and at both ends of the cable. I hope that helps.

[@erikin2k7]

Great video. Today I was talking to a friend of how to install the dvr usb using cat 5 cables and i just found this. As i saw, you are only using + and - cable for the video. so one cable can hold 4 cameras if you power the cameras locally.

[@cctv42]

Thank you for your comment. We find that over 60 metres you start getting voltage drop along the cable potentially causing the camera to malfunction. The video signal is not a problem - 300m is easily achievable - it's purely the power. I'd suggest you try to find a power location nearer the camera if possible.

[@cctv42]

If you've ever wondered how to use CAT5 or CAT6 cable to wire your CCTV cameras to the DVR here is the answer. Our most viewed video to date.

[@thejohnb]

THANK YOU!!!!!@@cctv42

[@formidable38]

Il be dammed, that stuff is just like common garden networking cable or even phone RJ45 cable. I was under the impression it had to be screened for noise suppresion and complex like a sat cable or something. Thats nice and simple, Thanks, very imformative.

[@carforumwanker]

Still the BEST supplier in the UK . Dont bother buying from others .

[@cctv42]

If you scrape back some of the copper see if there is silver coloured metal underneath. It may be that your video baluns are faulty. The UTP (uniform twisted pair) wire goes straight into the video balun. Also make sure you have the polarity correct on the baluns.

[@cctv42]

Yes, correct a single cat5 cable can handle up to 4 individual video feeds if the cameras are powered locally and we use this feature a lot with multi-camera cctv systems. Just plain old Cat5 cable. What I would say though is use pure copper rather than CCA (copper clad aluminium) because it works better and has less of a tenancy to break due to metal fatigue at the balun joints. Henry

[@Hubjeep]

Great video, and excellent point about using PURE copper CAT5e, a lot of "CAT5e" I see sold on the net and even in some stores is CCA (Copper Clad Aluminum), it may work, but does not meet some standards.

[@cctv42]

There are subtle differences between the two, but with the prices being so similar, you would be wise to go for the CAT5e cable. We've tested CAT5e with the passive video baluns at 300m with no issue at all - the only problem you'll have with that length is running the power over the cable. You will need to power each camera locally as opposed to with one central power supply.

[@cctv42]

@coldlogik You can do that, yes. The reason we combine the remaining 3 pairs is to reduce voltage drop down the wire to the camera. We have found that with 3 pairs for power, up to 60 or 70 metres should work fine (unless you have a camera with a high power consumption). I would guess at around 40 metres with your suggested configuration. Remember when installing to test with the IR on as well as off as this draws more power. Matt - CCTV42.co.uk

[@InventionPR]

In minute 1:38 i would recommend you to maintain the twist on the cable near to the baluns. At least thats how we (IT Technician) do with Ethernet Keystone Jack. Extremely helpfull video THANKS!!!!!

[@cctv42]

+InventionPR Thank you for your comment and I'm glad to hear you found it useful! Ensuring the wires are twisted as close to connectors is indeed best practice :)

[@Electroniks]

Hello there, I have exactly the same scenario as minute 2:28 but with the difference that i´m using two pairs of cable for the balun (one pair for positive and the other for negative) and the other two pair for the power source, but the camera is not working, do you think it might be a problem related to power? I mean, do i have to use three pairs instead of two in the female power connector? i will aprecciate your answer

[@hasibahsan3447]

I have a built in mic camera with one bnc connector and one adapter socket. Should i connect the video balun/transmitter same way?

[@cctv42]

It depends on the distance between the camera and the DVR / power supply. You might get away with 2 pairs of wires for the 12 volt power, 1 pair of wires for the video baluns and one pair of wires for the audio connection.

[@cctv42]

@ipsademexicotv thank you for your comments. When installing cameras outside, we always recommend keeping the connections dry. For this purpose you would be best advised to use a weatherproof enclosure of some sort. We stock one which can be seen on our website at: cctv42.co.uk/content/94/weatherproof-box-for-outside-cable-connections.aspx

[@cctv42]

Ok - to answer your questions in order: 1. In the video we are using CAT5e cable 2. Either CAT5 or CAT5e is fine - it makes no difference with this application. What does matter is ensuring that it is PURE COPPER, not CCA. 3. CAT5/5e should have 8 wires (4 pairs). If any less, it probably isn't CAT5/5e cable. Good luck!

[@gayanfonseka7397]

i have red and blue bullons. is it mind if i install them at any end of the wire. i mean red to dvr and blue to camera or blue to dvr and red to camera?

[@8Jallin]

my simple question is, Running cat5 instead of siamese cable is better for these type of cameras? (non ip cameras) ?? or is it just for emergency? because I rather use cat5 than stinky coax.. I don't like coax at all, good thing in the next 5 years all cameras will be ip cameras!

[@syedkazmi123]

Hi Henry Thanks. I need to know if there is any home made (DIY) option to replace a Moca Adapter. These Adapters are very expensive and I want to obtain same functionality by doing it myself. Thanks once again.

[@cctv42]

That would indeed work. As long as you use the same pair for each camera. Use: Blue+Blue/White - Camera 1 on the cable Green+Green/White - Camera 2 on the cable Brown+Brown/White - Camera 3 on the cable Orange+Orange/White - Camera 4 on the cable That will work, no problem at all.

[@embower3224]

Thank you so much! After this video I finally understood how to do this.

[@ParishRaut]

[@henryf9175]

Parish Raut Thanks for the kind words. glad it helped.

[@cctv42]

Thank you. You can for the video as long as the cable is Pure Copper CCTV Grade CAT5e Cable (I'd also ensure you get outdoor grade cable). I hope this helps.

[@cctv42]

You can indeed use CAT5e cable, but please make sure it is pure copper cable (not CCA) and if it'll be used outdoors, is external grade cable also - this is the type of cable we have available in our web store in the CCTV Accessories For Sale Page.

[@aneelrasheed]

We are in great trouble, we used separate CAT 6 cable for each camera and gave 2 pair to video and 2 pair for power using DC adaptor. We used passive video balun without power dc jack. Image is fine with no lines or interference but image has ghosting affect and double. What to do

[@cctv42]

Hi there. Without seeing the installation it is impossible to say what's causing your problem. I would start by checking the individual components on a short test length of cable. I would also use a single pair for video rather than doubling up, you need to triple up on the power to avoid voltage drop over longer distances. Check for outside sources of interference, look at the camera power supply, the cable used (is it pure copper solid uniform twisted pair), the connectors (many so called baluns are just connectors with no internal components), and so on.

[@cctv42]

Hi there. It could be a voltage drop issue at the camera. We would suggest a maximum cable run of around 50 metres when using CAT5 for both video and power, that is with 3 pairs of wire for power, 1 for the video baluns. You also need to make sure you are using pure copper CAT5 rather than CCA or copper clad aluminium. Many cheaper retailers will supply this in place of pure copper cable and it greatly reduces the performance of the cable.

[@abdulwadud363]

How would I knoe if I got proper copper cat5? Also which is better cat5 or cat5e? I'm also going a maximum of 10 metres so would your power and video balun connection be a problem for me?

[@Electroniks]

How can I know the real difference in the cables??, I bought a box of cable but it does not have the transparent plastic protection for the wires, it just the blue plastic cable and the 8 wires inside, the distance of the cables to the cameras is not longer than 30 mt. I have to mention that if i use a UTP to BNC converter all the cameras works perfectly, but when i try to build the connectors they are not working as I said. I will let you know what happens with 3 pairs for energy, many thanks!

[@cctv42]

If you're powering the PTZ camera separately, then you don't need to use the other 2 pairs within the CAT5e cable. You can leave them as spares for future use.

[@pierreciment9816]

That means a multitude of things but usually "I very much do have an opinion but I'm not going to tell you at this stage". I will tell you in the most vocal of terms when you get it wrong.....

[@cctv42]

@flamesecure None at all. The baluns are a very good way of transmitting the images. The construct of the cable ensures that there is minimal interference introduced into the image.

[@cctv42]

@formidable38 it is just standard 'networking cable' or UTP cable. If you're looking at using this type of cable for CCTV, ensure the cable is 'Pure Copper', not 'CCA' or 'Copper Clad Aluminium' (also known as 'Copper Coated Aluminium') as it is a better type of cable with better electrical properties. Cheers Matt - CCTV42.co.uk

[@DAM89]

How do you remove the jacket from the 8 internal coloured 0.5mm wires without cutting the copper wire? Ive struggled many times to find a cable stripper for 0.5mm cable but they seem to be non existent. Thanks

[@summerr911]

the 3 pair of cat5 for DC plug 1 end is going to camera, other end is connected to what device?

[@cctv42]

summerr911 They would be connected to the power supply for the camera assuming the cable run length is less than 60 metres. This can either be done by wiring the CAT5 straight into one of our Professional Power Supplies, or using a DC Socket and into either our Single Camera Power Supply or 4 Camera 5 Amp Power Supply.

[@musicwithlyrics7844]

Hi. Can you explain how you can feed 4 cameras on one cable. How would you make a split into the cable to keep running only one cable or would you need to keep splitting the cable. How does this work for power however each camera will need one cable for each power?

[@cctv42]

Handling the video feed from 4 cameras down 1 piece of CAT5e cable works best when the cameras are close to each other making connections easier. You could theoretically cut into the cable along it's length to use one of the twisted pairs for a camera but it's harder. The cameras would need to be powered independently from the CAT5e cable, you couldn't use it to handle multiple video signals AND power the cameras.

[@mrgreekish12]

Hi, im pretty new to wiring cctv using cat 5 (i tend to use RG59) are the positives on cat 5 the solid colours such asorange, blue, brown, and green and the negatives the colours following the white? also if orange is positive and it goes into the + of one ballun, would orange go in + of the second ballon? and from my understanding, you put the last 3 positives and negatives into the DC male and female with no order?

[@edwinpineda8922]

I am learning a lot from your video. Thanks.

[@cctv42]

You're most welcome.

[@IvanCoversPH]

Can we use 2 pairs for video and 2 pairs for power? Does it make any difference from what is the usual specially on the result of video fuzziness or power drop?

[@cctv42]

Joven Ivan Julhusin Hi there Thanks for your comment. The video signal only requires a single pair of CAT5e cores, whereas the power requires as much copper as possible, so you're best to stick with 1 pair for video, 3 pairs for power. I hope that helps.

[@hicoteo]

Can you use cat3 cable for camera installation? Will the image and power be ok even though the two pairs of wires are not twisted?

[@henryf9175]

+hicoteo You need to use twisted pair cable such as CAT5 or CAT6. It is the twisting which prevents interference.

[@vladislavstoynev1540]

If i use for two cameras, i am left with 2 pairs for power. You recommend cross splitting the pairs for power right, not one pair for minus and one fir plus?

[@cctv42]

Hi there. We wouldn't recommend running 2 cameras using 1 length of Cat5 cable if you are using that cable to power cameras. There is a danger of voltage drop if you only have 1 pair of wires for the 12 volt power, hence why we suggest using 3 pairs for the 12 volt power.

[@Sparkette]

How do I connect this type of camera to a standard consumer TV? Can I just connect it to the cable input without bothering with any of this, and I guess put it on channel 3 or 4 or whatever?

[@cctv42]

It depends on the camera. HD cameras will need to go through a DVR recorder then into the TV via HDMI. A standard definition camera could theoretically be wired directly into the AV (yellow) input if the TV has such a thing. You could only have 1 camera and of course it wouldn't record.

[@joyboyboy1]

thanks for the advice will try it out on the weekend

[@deedee3495]

Hi mate do you not what resistor I would use to link the ground of the video with the ground of the power feed or is it ok just to link the 2 together. I ask because i have 40 meter 3 core cctv wire left over that i want to use but the ends with the connections have been cut off. This is the proper camera wire that you get from ebay. Who you have any idea.. Thanks

[@cctv42]

The words "proper" and "eBay' rarely make happy bedfellows! I'm afraid I don't know what you would need. Video baluns are designed to be used with uniform twisted pair networking cable. As an alternative to this for CCTV we would recommend RG59 coax cable with a 2 core "shotgun" cable to provide power to the camera.

[@elderizm]

Hello and good job! I just want to ask you; What If we gonna use just 1 cable for power connector? With same way same cable system via cat5e, I mean for example orange and white cable for power... Not at all cables. 2:27 What happened then? Is it still work or not?

[@cctv42]

You are likely to suffer voltage drop as the cable length increases. We suggest using 3 pairs of wires for the power to ensure sufficient copper content to avoid voltage drop.

[@cctv42]

When you use the Cat5 UTP cable to run signal from 4 cameras as in our example on the video you will have to power each camera locally because there is no remaining capacity, all the pairs have been used for video signal. Each pair of wires can only do video or Power, not both at the same time. Hope that answers you question and sorry it took up 2 posts! Henry - CCTV42.co.uk.

You can't supply power to 4 cameras and send video back to the DVR using a single length of CAT5e. You would have to power the cameras locally then just use the CAT5e for video with 1 pair of wires to each camera.

[@ALSNewsNow]

I have heard that the twists make the 12 volt power unusable? Any truth to that?

[@henryf9175]

No, you can quite happily power cameras using the method we describe in the video.

There are cable strippers out there that can be adjusted using a screw to the diameter of wire you need, including CAT5e cable. Good luck!

You should never cut the flylead which comes from the camera. This will invalidate any warranty and you could end up damaging the camera. Excess cable can be looped outside the box to form a drip loop.

[@rizwanmahmood1407]

hello there... good explanation, however not sure why you would need to tie the last six cores into two sets of three to prevent voltage drop? when a single pair can provide 48v @30watt - we see this on standard network topologies when running POE devices ie Cameras, IP phones, Wireless access points etc.. perhaps i misunderstood what you were saying

[@cctv42]

These are not IP cameras, in this example we are using CAT5e cable purely for the copper content. The cameras are 12 volt which will increase the chance of voltage drop but with any wiring using thin wires and lower voltages voltage drop is an issue as cable runs increase in distance so trebling up acts as insurance policy.

[@rizwanmahmood1407]

@@cctv42 thank you for the response, I appreciate the example you have used are not IP cameras I guess my reason for the comment wsd purely the fact that poe devices run 48v on cat5e and cat6 onwards cables albeit with them being thin cores..

[@cctv42]

@@rizwanmahmood1407 these are not PoE cameras in the strictest sense of the meaning. Because they work at 12 volts there is more chance of voltage drop compared to 48 volt devices. It's why the large power cables you see across the country run at 400,000 volts. CCTV applications are unique in that long cable runs can sometimes be required, certainly longer than might be experienced in a home or office set up and you won't have localised power injectors as you might in a network.

[@lgonzalgonza]

Why must remaining twisted pairs be set to power and ground? also is it necessary that all remaining pairs go to ground and power as oppose to just 2 or 1?

[@cctv42]

[@cctv42]

Use decent cable. I suspect your cable is CCA or Copper Coated Aluminium which breaks easily. Try scraping the copper off one of the wires to see if you can see silver underneath. Good quality Cat5 cable is pure copper and because the copper is more malleable it tends not to snap off. You have to use pure copper Cat5 with video baluns, particularly as the runs get longer to avoid signal break down.

[@georgexedos4342]

Useful video!!! but i need to ask somthing more: the distance of my cameras will be from 40 to 50 m is the cat 5 useful? do i need balluns? and is there cat 5 with 8 pairs of cables for 2 cameras useing only one cable/ thanks in Advance!!!

[@cctv42]

At 40-50m we would suggest powering the cameras locally to avoid voltage drop. CAT5e comes with 4 pairs of wire, you would need to run a second cable. If you are powering the cameras locally (ie. not using the CAT5e cable to supply power) then as you only need 1 pair of wires for the video feed up to 4 cameras can be handled by a single length of cable.

[@cctv42]

Hi there. I don't think using a single pair of wires for the power supply on a PTZ camera will work. PTZ cameras have higher power requirements due to the motors and so you will suffer voltage drop. I would suggest powering the camera separately. You could then use 1 pair of wires for the video and 1 pair for the RS485 control. The wires need to connect to the video output & RS485 control on the camera, the DVR video input and what ever you are using to control the PTZ at the other end.

I even tried running local power to the camera and it made no difference so at the minute I'm sending power and video through the same cable.any info would be great..Thanks

[@cctv42]

Interference can be caused by many things. Certainly using good cable is the first thing to eliminate. It could also be a power supply issue, the baluns or the cameras themselves. Whilst you powered the cameras locally was that using the same supply? It's a problem when people buy different components from different places and throw them all together. Sourcing from one place you have a single point of contact and hopefully the vendor has checked everything for compatibility although I appreciate in this day and age that isn't always the case.

[@deedee3495]

Thanks for the reply.Yes i used the same power supply its a 5 amp 1 from ebay so can power all the cameras with 1 unit.

[@deedee3495]

Ok thank you it was to do with power adaptor but u have also discovered something else which might help other people I removed all the ground wires coming from power adaptor going to the cameras and they are perfect now, there are using the ground wire from the AV video feed so maybe problem is there is to many grounds that causing interference. But this would only work if you're using the same power adaptor that you power cameras and dvr. So a 5amp will do 4 camera and the dvr. Give it ago and see. Im goin try tomorr on that system i used the cat5 on to see if it takes way the we lines

[@cctv42]

We wouldn't suggest powering the cameras and DVR off the same supply. All our DVR recorders are supplied with their own power supply, it is important to use this. Be aware that a DVR uses more power than the cameras to it would be possible to overload the power supply.@@deedee3495

ok thank for taking time to answer, I had tried with 3 pairs for energy and is not working yet, I will change the balun maybe it´s damaged.

[@najb7775]

sorry its me not explaining myself properly the cables that i meant were the ones going to the balun & the the one going to the dc power not cutting or shortening the camera cable , if cables were left in a loft space would you tape the bare wires? also is this the same core wire that you would sell with your B7 camera, would you always put all the remaining cables 3 pair to the dc is this so there is not voltage drop ( great videos by the way i am learning alot from them as a complete novice )

[@cctv42]

The Cat5e cable can be cut to length, the video baluns and DC plugs are designed to be fitted by you using a small screwdriver. You could use tape, although sometimes that can make checking them difficult. The good thing about a plastic enclosure is they can be easily accessed if you need to change or check anything. We do sell external Cat5e cable on the site. Cameras are supplied on their own, you need to order cable & connectors separately. Thanks for the kind words.

[@dalitiko]

Hi. Thank you for this excellent video. Do the baluns have polarity? If they have, how to connect? from one balun's Positive to possitive on the other balun, or positive to negative? (invert)

[@waelja38]

what is the name of the connector for the power supply to the camera

[@cctv42]

We call the DC plugs at the camera and DC sockets at the power supply end.

[@fatihaker827]

Thanks for the video. I wonder whats the max range of this application ? Do I need to use these baluns for 200mt distance between camera and dvr ? Or is it much better to use coax ? Do you recommend 16ch balun recievers instead of seperated baluns for each camera ? Thanks

[@cctv42]

We suggest a maximum cable length of 50m when powering the camera via the Cat5e cable, 100m if you power the camera locally and only use the Cat5e cable to transfer video signal. The balun manufacturer claims a maximum distance of 200m but we prefer to play safe. We don't sell multi channel baluns.

[@abdulsaeed2]

Hi, Two questions, Firstly when using cat 5/6 you get ghosting, rolling, rainbow effect, how do you eradicate it? secondly what is the max length I can use for either Bnc cameras or IP based cameras??

[@cctv42]

Hi there Abdul. This method would only be used for standard definition or HD Analog cameras such as HD-TVI, HD-AHD or HD-CVI. Make sure you use pure copper CAT5 or 6 not CCA (copper coated aluminium). Use shielded cable and also make sure you are using genuine video baluns rather than just connectors where the terminal wires straight through to the BNC fitting. There are specific standard definition and HD video baluns. The maximum length will depend on a number of factors. Assuming just video transfer our equipment allows for a maximum connection length of 300m. If you are also supplying 12 volt power down the cable we would suggest a maximum cable length or 50-60m depending on the camera.

Thanks a lot! This video is amazing!

[@ArabDevops1990]

very good explanation

[@ipsademexicotv]

Your video is excellent ,1 question How do you recomend installing on the outside ?? should i just use a 3M Electric Tape all around the balun and ac plug???? Thanks in advance Robert

[@jerrymauleon]

great video! very ilustrative! i have a question about the polarity of de cable. The solid color lines are the positive pole? (red,blue,green) and the the white cables with a thin line color is the negative pole of the cable? im mexican sorry for my bad english.

[@elderizm]

Hello and good job! I just want to ask you; What If we gonna use just 1 cable for power connector? With same way same cable system via cat5e, I mean for example orange and white cable for power... Not at all cables. 2:27 Or Positive: Orange and White and Negative Blue and White... BNC: Positive: Green and Negative:White... Red: Internet service provider and White: Internet Service Provider ISP... What happened then? Is it still work or not?

[@cctv42]

You wouldn't be running the internet service on your camera to DVR cable. Our DVRs connect to the internet separately allowing you to access your cameras remotely. For this application the CAT5 cable only takes 12 volt power to the camera and a video signal back from the camera to the DVR.

[@willyguy100]

good video ... helped me a lot ..

[@km42019]

I find your video very helpful, Is it possible to connect a analog camera to a NVR over cat5 cable

[@cctv42]

No, IP cameras and HD analog cameras are not compatible.

[@hariaditya7923]

Kitane meter tak kaam karega normal DVR me

[@nanakwamenk4900]

nice video its very educative

[@Saturn5Rocket]

Very Nice video, congrats. I have a DVR kit and cameras came with a 60ft cable. Can I use female-to-felame connector ad the end of the cable and then reach the DVR using cat5 cable following this video? Thanks in advance!!

[@kanalord4134]

Thank you this was helpful, can you show how to connect cat 6 - to- Balun- to- IP camera ( Ethernet Port ). I have only wires to take Video to my system. So I could use a Video Balun as you have shown and connect to a standard BNC. Now suppose instead of a BNC male out , I have an Ethernet output as we have in IP cameras. Can I use some sort of adapter to convert Ethernet out to two wire out.

[@cctv42]

IP cameras are a totally different entity and have nothing to do with BNC connectors. We don't sell IP CCTV systems for a number of reasons outlined here on our website: www.cctv42.co.uk/help-advice/buying-guides/buy-the-best-hd-cctv-cameras-and-system/ip-or-analog-hd-cctv/ IP cameras work with an NVR, our HD-Analogue cameras work with a DVR.

[@Finishthelyric]

Hi Henry, Many thanks for uploading this informative video! Could you advise what you would do with the baluns on the camera side when they are used externally? Do they need to be boxed? how are they waterproofed? Many thanks in advance!

[@zakbora]

thanks suppose I use 12 volts 3Amp or 5 amp power switching supply can I get up to 100 miters?

[@cctv42]

No, the voltage drop along the cable is voltage based not current based.

[@frhwebmaster]

HD-SDI no more than 50 meters. Many say cannot be done. Others say can only be done with specialized Balun that are expensive. Can you specify, if you have the time. Thank you.

[@cctv42]

HD-SDI was a bit of a stop gap solution for analogue HD and we never sold it. We use HD-TVI which is much more tolerant to cable length & type. HD-SDI is very fussy both in terms of cable spec and length.

[@frhwebmaster]

CCTV42 Thank You

[@abdulsaeed2]

Hi, if I use HD cameras with these attachment using ethernet cables, will I still get HD picture? thanks?

[@henryf9175]

+abdul saeed Hi there Abdul. If you follow the link at the start of the video it will take you to the baluns on our website. You will see we have an HD version which is suitable for HD cameras up to HD1080P.

[@cctv42]

We supply HD-TVI cameras and these can be connected using CAT5/6 cable and video baluns. We sell specific HD baluns for the purpose.

[@anonymoussafricaforafricans]

this is great , cat 5 and 6 cables has gone a long way to eliminate the waste of cables to hv power near the camera when using siamese

[@abdulsaeed2]

So do I need HD balums for likes of 3MP TVI cameras using cat5e? this will eradicate any interference?

[@stuneedham2829]

Theres a lot of work to be done if you want to upgrade to an I.P. system. Plus, if you you all the remaining pairs for power, you run the risk of ghosting the picture through interference.

[@cctv42]

This method of wiring is suggested for HD Analogue systems not IP systems. IP CCTV has it's place but we aren't massive fans for reasons outlined here: www.cctv42.co.uk/help-advice/buying-guides/buy-the-best-hd-cctv-cameras-and-system/ip-or-analog-hd-cctv/
