Cctv Psu Connections

[adrian SA]

Hi all

I cant seem to find the CCTV regulations anywhere on the web.

If I am installing an 8 Amp PSU for a CCTV system, can I wire a plug onto it and plug it into a normal 240VAC socket, or do the regulations require me to connect it into a fused, unswitched spur ?

I know some small PSUs are supplied as plug-in units.

Some advice please.

I cant quite believe i am answering this question but of course you can!

The worst that can happen is someone will unplug it and the camera's will go off and thats where the real questions will be asked!

8 amp psu for all cameras mm

I have had problems with ghosting doing this.

I always prefer unswitched fused spur for camera psu's and the recorder when possible, or out of reach of the cleaner.

Why?

Ghosting is usally caused bay incorrect termination, running 2 signals down a multicore, poorly grounded video cables. strange to get ghosing problems using a single PSU.

I am a surveyor, and I getting attitude from one one my installation engineers who insists that spur for the PSUs are part of the NSI NACP20 regulations for CCTV

He is quite probably correct and if the installation is to regs then...........personally i have no idea but it would make sense to me.

Do you not quote your CCTV installs to a standard then( NACP 20), surely you have a copy to work from?

I thought it was common practice to wire all CCTV equipment via non-switched fused spurs we do it all the time, including DVR's, video's and monitors.
