cctv keeps blowing a fuse

[Menaice]

I have a client that had a cctv system installed about 9 years ago, 12 cameras running, they all work fine. they wanted to add 1 more camera. i myself have only done IP cameras using POE. The dvr is pretty old but works and there is a power supply box.
The camera i ordered for them is a
Hikvision DS-2CE56D7T-VPIT
The dvr they have is a wirepath WPS-365-DVR-16CH

The power supply box is an Altronix ALTV248
See pics of the power supply here

its a short run to where the camera is mounted, about 40 feet. I run the line, plug it into the dvr, Then connect the power to the Power supply, NOT connecting the camera at this time. The fuse doesn't blow, I took my multi meter and tested continuity on the cable and it beeps. Don't seem like the cable is the issue. Soon as i plug in the camera it blows the fuse instantly.

I didn't take the camera and put it on another working on, i don't want to turn a small issue into a bigger one since all 12 are working. What am i doing wrong? is the Power supply to much for this camera?

Such a simple job is doing my head in, I am no electrician but i never have these kind of issues with IP POE cams at all.

also to note, which i find confusing to me at least, i put my multi meter on the Power supply hot and ground and get 28v. then i test the end of the cable where it plugs into the cam, it test the same 28v. IMO that seems like a hell of alot for a security camera

The camera you specify is a 12V DC.
The power box is a 24V AC.

Some analog cameras can operate on 12v DC or 24V AC. We mainly used 24V AC for outdoor ones that the camera boxes that had fans or heaters. Some would convert down to 12v dc. Other times for long camera runs.

Adapters exist to convert the 24v AC to 12v DC. https://www.amazon.com/Convertor-Security-Camera-Supply-Adaptor/dp/B008EPKLRK

My guess is all 13 cameras have to be drawing more then the amps that box is pushing it shows 4 amps even with each camera drawing 500mapms your over.

Put in a proper supply box. And as for 28v these boxes can usually be tuned slightly above the rated output to account for power loss on longer cable runs.

And as mentioned that camera is 12v if you want to use it purchase a 12v wall wart and plug it in and just skip the altronix box.

Any supply house like greybar tri ed or Adi will have what you need.

Yep that would work perfectly. Used adaptors like that countless times for small 1-2 camera installs where a full power box isn't necessary.

Ya you will have no issues with that.
