18 Channel/Port 30 AMPS, 12V DC Power Supply Box, Individually Fused for CCTV, LED, and All 12v DC Devices. (18CH 30 AMP)

I usually wait for a month before posting any reviews, this has now been in service for 2 weeks. This unit definitely supplied the current necessary to drive all of my cameras on 100' ft plus wires and revived the ones that had infrared issues now I have 15 cams that work and one that is inoperative and needs replacing so now I will get one new camera. This unit has the capability to run 18 cameras so I have 2 unused ports but that's ok. I did have to buy some DC pigtails to install in the box for each camera as they were not supplied with the power box. Over-all it was a really good buy and I will be buying another one for my camera system at home. (I have similar problem on that one as well) This box has 18 camera capacity @ a total of 30 Amps capability divided between all outputs which means each one has approx 1.6 Amps to each camera @ 12 Volts, provided you use all 18 outputs, if not then divide the 30 amps by the number of cameras that you attach to it and that will give you the available current for each camera @ 12 Volts. Ideally, most cameras require about 1 amp of current @12 volts to operate properly but when you are using 100 ft of cord on each camera the current and voltage can drop way off down to somewhere around 7 volts which some of these cameras will not operate very well at that voltage causing the infrared to be sometimes ok and sometimes not ok. I have not yet measured the voltage level at any of my cameras since the upgrade but they are all working very well so I am not to concerned with any of them working in a gray area any longer. Hopefully this post will answer any questions that you might have especially if you are like me and have a cameras that work only part time on 100' long wires. I have 16 Cameras and I am running 3 different kinds (Brands) of cameras which is probably why some worked ok and some didn't on the provided power transformers I had plugged in to a power strip..... don't use those if you can help it otherwise you may have the problems that I had. Again great power supply panel for CCTV camera system.

I am using this 12v dc power supply for my O scale model railroad build of 40 x 45 and it is working very well. Bought another in case I needed it.

The cabinet thinly made but the power supply works fine.

Our cameras are back on line! Thank you.Only suggestion would be to space the plug in receptors a bit further apart.It's difficult to plug in if unless you have tiny hands.Otherwise, this is a perfect product for your needs.

connections are too small , also fuse are very low resistance and blow out during installations of cameras not worth to buy and after use of spare fuses this power supply is useless

It work great.

I am a commercial security camera technician. Over the years, I have used a variety of enclosures similar to this one and they all are about the same with a few basic differences. I ordered this panel for a client because they had their cameras connected to a patchwork of mini power supplies and they burned out leaving them with nothing. It is always a good practice to install a power panel each time. The main reason(s) why I say do this, is (01) it offers a more professional appearance, (02) it provides balanced power to each camera (especially over longer distances), (03) each circuit is individually fused for protection not only for the panel but for any equipment that is connected namely cameras. If one should happen to go out, it is limited to just that camera, the others stay online.

I bought this to power my 8 security cameras. I haven't finished installing it yet, but I have some observations based on some testing that I have done.Things I like:- the power switch and AC input connections are inside the locked box.- the cutouts have grommets for wire protection.- each camera circuit is protected by a 1A fuse rather than a series PTC varistor, which could limit camera current.- each camera circuit is protected by a Metal Oxide Varistor (MOV) for voltage spike protection.- there is an adjustment for power supply voltage, if needed.Things I don't like:- the power supply is the typical no-name switching type. All switching supplies produce noise, and with no load, I measure +20 mV/-10 mV noise at 62 kHz. The capacitance of the camera cables should attenuate this so it isn't a problem (I hope).- the power cord is very cheap and is only 2-wire. If you want this to be grounded, you will have to replace it.- the decal on the inside of the lid is for an earlier version and doesn't apply.Verdict:- not a bad unit, especially for the price.I will post an update after everything is hooked up and running.
