Great video. Very informative. Making the right choice between 2.8/4/6mm is very important. I agree that for residential stuff, with 16:9 widescreen cams (e.g. 4MP, 4K), 2.8 is usually the most useful. That said, while not great for entertainment, the 4:3 aspect ratio stuff (e.g. 6MP) works a lot better for video surveillance. Regrettably, all the best stuff comes in widescreen lately because it dovetails with the entertainment format.

Been using hikvision for about 5 years. Initially 4mm on 4mp cameras on the front and side. Decided to go for 2.8mm and 8mp camera on front to see everything coming towards house. The wider angle looks like it comes from further/back but with the higher megapixel you can offset that by zooming in further without losing detail. Yours looks far better with that angle as well 👍

I would say not unless you have the vari focal ones. The 2.8mm is zoomed out slightly to achieve the field of view.

@@DIYJourney1 that’s why it’s better to go higher with the megapixel on a 2.8 if you can. From the angle on my 4mp 4mm with passing vehicles on road if I paused the video at a certain angle and approach I could use digital zoom and just about read the number plate. With the 2.8mm 8mp same position although it gives the look of set further back to give the wider angle I can digitally zoom in and pick out the number plate no problem.

@@RDJ9887 hi, I’ve had no degradation I’m still running one of my original 4 mp cameras in the garden from back in 2016 still works great. As I’ve increased the mega pixel on 3 of my other cameras to 8 mp the nvr runs them normal but hikvision updates the nvr software to 4.0 and that’s where it became a problem. My 2nd nvr is a k series and it was terrible on 4.0 so reverted back to the original software. If you’re going down the nvr route on hikvision make sure you get the newest nvr in the price range. That’s the only problem I’ve had. The original 2016 76** nvr was struggling with the higher mp cameras so about 3 years ago purchased the k series but what I thought was the best at the time wasn’t and is totally underpowered to handle the new software and the new features in the cameras.

Great video! Question, why didn't you mount the camera in the other corner above your door so you can see who is walking up to your front door? Now a big part of the view is taken by the wall/garage doors and someone can come up to your garage door with his back towards the camera.

Bit of advice from a police detective in New York. Fix your lighting problem first. While cameras are great, good lighting has greater potential for deterrence. I've been through the process of taking video to make arrests, both on the job and via doing camera work as a side business. The perps on the video have already sold your stuff by the time they are caught. Depending on your state, you may end up having to take 5-10 days off from work to attend every hearing. If you get lucky, they are ordered to pay restitution, $20/mo for however many years it takes. Lighting/deterrence is the first priority.
