Thank you Sir, for sharing your knowledge...

Thanks for the tutorial. When I install a wifi camera with a 12v power adapter, it can be plugged into the 127v outlet (type 20m away) and wired to the camera using a green adapter that you show in another video, or the power adapter must be installed near the camera (so there is no loss of current).

Where can we find that blog to calculate power over long distance ?

Will 19.5V - 2.3A - 45 W. Work on a box camera?

[@LearnCCTV]

That depends on you camera specs. Most cameras work with 12V be careful to not burn it with 19.5V. Most of them also need around 11 to15 Watts, so 45W is overkill. The best thing is read the specs and use the power supply the camera needs.

If we off gernator power suplly will camera off will camera record then or stop

Help me design a off grid solar 12v PTZ camera that can run via 4g cellular network . If you can do a video on that it will be great. Will i need a NVR, charge controller and POE with RJ45 cable?

I've got horizontal lines on my 16 channel cameras. Is it power issue and how to fix it? How much Amp per camera must give, 1.5 to 2? Does ohms matter 50-60

@@LearnCCTV thanks you for this article. It's very helpful.

I have a camera system that is blowing fuses on certain camera's...I replace the fuse and it blows again as soon as I power up Any idea's?

[@LearnCCTV]

Check the power supply or PoE switch (if you using one). It looks like the camera are getting excessive voltage.

[@abelloise]

@@LearnCCTV its on a circuit board with all the other camera's fuses and there are a handful that are not blowing...if it was power wouldn't it blow all of them?

[@LearnCCTV]

@@abelloise That' depends on the specific situation. With longer cables, there's a drop I the final voltage, some power supplies also control how much power you can send to each individual camera. I suggest you to use a multimeter and check the voltage that arrives on each camera to see if it's excessive. You can also replace the power supply with a professional one that controls the voltage per camera. Last case scenario, the camera could be defective.

Them power supply boxs are waste of time
