12AWG wire has a resistance of 1.62 Ohms per 300 metres.

However, we wherever possible would fit the psu close to the camera in the 1st place to avoid current loss. 

If this is not possible it is always better to over specify the cable (Its the cheapest bit of the installation but can become the most expensive).

It is a bit horses for courses and if your psu,s arent local how much cash would you save by using alarm cable over 1m flex?

Pete :rolleyes:

Hmm, doesn't matter whether it's a Sony or Sharp chip or how many TVL's, that won't do the cameras any good. ;)
