I'll eventually put an IP camera out on the chicken coop but for now I have a nearby trailcam trained on its doors. Recently a couple of birds were mauled in the coop after the hatch opened in the AM and after fixing the chickenwire bird run I found on the trailcam a large raccoon returning at night trying to get back in. It then got trapped and relocated. I have an IP camera from a back window of my home trained on that area from a distance and at night see when a cat or critter triggers the trailcam the flash of the IR. Of course the IR isn't visible to the naked eye at night except for the light red glow on the camera itself when triggered. I bought a 48 LED IR light which will sense dusk and dawn. It came with no documentation. I don't know what voltage or current it requires. I plan to mount it on the coop and have that area lit with IR dusk to dawn not just when the trailcam flashes.
I have numerous 12 vdc supplies left over from my bitcoin mining days and switching modules that can step it down if it runs at a reasonable current. Not wanting to go that way, I want to harvest an old wall wart to use because the insect population around the coop invade anything that isn't well sealed. I was just going to put a .1 ohm 1% 25 watt resistor in series and calculate the current, figure the power and add 20% to characterize the wall wart I'll need. But then I figured if it's expecting a current source and if I put it on a 12dc supply of some heft I could burn out LEDs especially if it's only expecting some voltage limited to say 6v.
So, anyone know what this no-name 48 LED IR light expects? It doesn't lend itself to being taken apart from what I see.
