You can use these VoltDevil devices adjacent to your camera to ensure that you are supplying the camera with a quality 12V DC regulated supply.
For example you have a long cable run and 12V DC is insufficient for the length and the power drops off before it reaches the camera. Here you could use a 24V AC supply and fit the VoltDevil at the camera end to deliver 12V DC to the camera.
Provides a 12V output from a 18-24V AC input!
The diagram below shows another example, here you only want to use one power source. See how the VoltDevil power supply regulator fits easily into a typical CCTV set-up.
Useful for converting a 24V AC supply from a power source or PTZ equipment into a regulated 12V DC supply for a camera.
Typical example where the installer wises to use the same supply to power a 24v AC PTZ and a 12v DC camera.
