Hello everyone, I have several security cameras around my home. All of them are night vision cameras. It seems that the LEds in these cameras do not last very long. I have been purchasing a replacement LED board for each camera, however they do not last longer than a few months. The board replacement is very cheaply made (in China) and tends to blow more easily. All of the power supplies for each camera are clean, and working. I have other more expensive cameras where the LED's never blow (not in 10 years) So I want to ask if anyone knows of a mod to one of these boards. Maybe the current limit resistor is not the correct value? any help would be appreciated. Thankyou

i have separate power supplies on all cameras, crappy cameras are blowing led's rapidly. the replacement LED boards I get from China are worse, and the LED's last about 3 months until they are all blown. Originally I asked if there was some kind of protection circuit i could add on the board but I haven't received a response yet.

Well the LED's didn't blow for 5 years, now they are always going within a few months. How long should the led's last in a good camera running 24/7/365? Any links as to where I would buy a good camera?

only some of the led's are blown. the cameras are not crap, the replacement LED boards are crap. I thought there may be a protection diode or some other mod to add to the board to prolong the life of the LED's. Anyone?
