Very good!. Requests: 1) how do you know which leds are in series? Do you have to test the soldering of the LEDs one by one and make a drawing? 2) how do you understand the polarities of soldered LEDs? 3) what type of new LEDs did you purchase? That is, they should be qualitatively identical to the faulty ones, but how do you understand which ones to buy?
The advantage of infrared at 850 nm is that it is visible as a faint red glow to the human eye, which is not very practical for video surveillance, because a malicious person will quickly guess the presence of a camera.
