At least keep the Power cable away from the signal cables, as the current in the power cable will emit interference as the load is inductive (motor), spikes, RFi interference etc.

Don't run low voltage supplies or signals in the armoured mains cable, there will be inductive coupling and capacitive coupling that will induce high voltage spikes in the low voltage cables, that can damage electronic devices.

I developed a CCTC drain camera years ago that was on the end of 100 mrs of cable, screened lead for the video, plus power for the camera and 24v for a 10 w 12 volt halogen bulb which at that length received 10 to 11 volts due to losses, no interference problems ever, Rick

is there a drain that runs past the gateway? if so you could use one of Rick's cameras - job done

Poor Sparky but good donkey. Let me know when we are doing it!

how is this project going?

Why don't you run a cable - be it 200M from your house to where you need the camera. Connect the output of a transformer e.g 230volt primary to 30volt secondary to your cable.

At the far remote end of the cable rectify the A.C to DC with a bridge recrifier with an electrolytic capacitor at the output say 10,000uF - into a 7812 voltage regulator and there is your 12volts at 1amp / or 2 amp depending what rating 7812 you buy.

Very simple to put together

Many thanks to PLANK and glanrichbex for your interest and practical information.
The project is on hold at present, too many others on the list and this one is not at the top. However when it does come to the surface glanrichbex's advice will be very useful but I'll need to consult again to put it into practice!
Thanks guys, rgds CL
