I've just bought a 12vdc alarm quad PIR (as suggested earlier in the
thread), seems I'll be back as the spec says "alarm" will output 24vdc yet
the IP camera I/O is rated at 5vdc ;#

Its more likely that you have misread the instructions.. all the ones I have
seen are 12v supply, a micro switch for the tamer loop and a pair of relay
contacts, volt free, rated at 24V or more.

The camera input will probably be a pair pulled up to 5V via an internal
resistor that you can short to make it switch.

Shame you aren't reading what I say anymore.
