The CM19 will send and receive RF signals. The motion sensors send RF. The TM751 hears RF and translates those
commands to the powerline.
The cameras transmit video signals (on a different part of the RF spectrum than the motion sensors, CM19, and TM751
work on ). The camera's power supplies act only on powerline commands.
The socket rocket will act on powerline signals only. So if you
have it set to A3, the S.R. will turn on either when the A3 motion sensor is tripped, OR as indicated previously, when
the A2 motion sensor 'sees' dusk and sends it's A3 On signal. I recommend you bring ALL equipment in close proximity
and run thorough tests for functionality and reliability. Once you've determined that everything is working as expected,
then move the A3 equipment out while rechecking reliability. In any case, the TM751 is critical in your installation
as it will be 'hearing' the RF commands from motion sensors and the CM19 and putting those commands on the
powerline to control the camera power supplies and the socket rocket.
