my mates workshop has been busted into so we have fitted some infra red ccd stuff to catch the c--nts the next time they try it on. the problem with the system is that the 240v supply is really tempremental and has a habit of cutting out every couple of weeks. it will be out from anywhere between 1 min to 12 hours. when it comes back on the system needs to be setup again. there are five pieces to the system- a black and white CCD cam with motion detection and infra red, a secondary infra red light source, a video switcher, a VCR activator and a VCR. the switcher, activator and cam all run off one 12v transformer. the secondary IR light has its own 12v transformer and the VCR runs on 240v. I was thinking that perhaps i could use a pair of 12v car batterys wired in sequence hooked up to a car battery charger. then, to power the equipment, i thought that i could use a step-up transformer (like the ones you get to turn 12v into 240v for camping etc) hooked up to the charging batterys. what do people think of the setup in theory? i realise that a lot of it will depend on power demand of the equipment but how about the rest of the setup?
