Have 12 of the above models....these are the ones with 30 LEDs arranged around the camera lens. They're usually treated as throw aways once the LEDs degrade or stop working. Bought a bag of 500 850nm IR LEDs from Alibaba for under $20 and fixed all of them. Toward the end I could R&R the unit in about an hour. Kinda satisfying to get these done. IR distance is as new again.
