Good OEM replacement transformers for CCTV cameras. They are fairly cheap compared to OEM transformers and will provide you the opportunity to change the factory ratio of 4 cameras to one transformer or more. When you use the factory ratio of 4 to 1 or 8 cameras to one transformer, they tend to over heat and die sooner. When you change the ratio to two to one, your picture quality is better and brighter for one and the other is they run a lot cooler which means they may last a bit loner in the long run. Since most CCTV units run 24/7, they are working all the time. It may be a good idea to have extra transformers when one these transformers die. The bottom line is that these units are fairly cheap and easy to replace, they are all made in China now.

Had purchased 2 lamps - one didn't work. After experimentation turned out it was the adapter that didn't work - not the lamp. Searched around and found this adapter which has solved the problem. The original adapter was L shaped and this one is straight but it makes the lamp work which is all that really matters at this point.

I've been very impressed with this power supply. I have a garage door open/closed monitor that needs excellent power regulation, and this power supply has been absolutely perfect!
