IR LED repair - cctv camera not working at night 

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?

HY sir hoping you are fine Sir what is the name of this tool you are using for pulling the LED

Do you have a link for the leds? Thx 👍
