I have a Wisenet 16 camera system and after only about a year or so cameras started going in and out at night, then completely. I was able to reboot the system, and switch pigtails, and unplug the power supply for cameras and everything would go back to working for a little bit until it didn’t. So, since I knew the cameras are good I knew I needed better power and my system initially included 1 plug for 8 cameras and 2 for four, I decided to go with 1 per four so now I have 4 power supplies versus the 3 before and each has 4 cameras (I updated the pigtails too one power supply had 8, the other two had 4 each) and everything is looking pretty good!
The cables were thick even thicker than those on the original, everything fit original connections, and with a regular plug, I was able to save space on battery backup because the boxes were further down the line versus built into the plug.

All-in-all a win win situation!

Top Critical Review

Power brick is EXTREMELY light. Basic stuff, they’re not using a good transformer from 120VAC to 12VDC.
You get the transformer right from the get go, you save a lot of effort past that. A good transformer and full bridge rectifier are the pure simplest circuits for that. Put some stuff in for noise supression, but still the simplest level.

Used to test with a 12V 2A load for an old fan. Failed within an hour of use.
Sparks whenever plugged in now, but no voltage on the other end.

Will cut apart the brick tomorrow and add photos when possible.

Customer Questions & Answers

This new power adapter gets very hot why does it get hot when hooked to my security system?
Answer: It gets hot because your security system uses almost as many amps as this power supply is rated for. Your power supply is working near its design limit.

If you want it to run cool, buy a power supply that is rated for about double the number of amps.

Will this be compatible with pioneer ddj 800 (5.5mm x 3.3mm x 1mm pin (positive) in center ?
Answer: No, the DC jack size on this is 12mm long, 5.5mm outer diameter and 2.1mm inner diameter.

Does this work for echo dot (3rd gen)?
Answer: My apologize, I don??t know. I don??t have an echo dot. Hope you find your answer soon.
