Just off the switch, dude. It's pretty safe. If you want extra protection, just wear a plastic shoe and a glove. If your priority use of Remote PTZ home automation is for lighting, then I suggest that you can place your TX the same level with your RX for better signal transmission.

Gently remind, the DVR PTZ setting have to change to PELCO-D for the channel you wish to control the home appliance. For autogate, door access system and alarm system, your Remote PTZ receiver setting have to change to Trigger mode. Use the Remote PTZ DC receiver, there are two wires, just parallel them to the Push Button Wire of your system. For the lighting and ventilating system, you just use the default mode, it is already set. For lighting, if you want to connect to AC230V lamp, then you have to look for the cable, usually, it has three cables, one is Live, one is Neutral and one is Earth. You connect the Remote PTZ AC receiver to the Live and Neutral, there are 3 wires in the Remote PTZ AC receiver, labelled as AC in, Neutral and AC out. You let the Live wire connect into the "AC in" of the AC receiver and then the "AC out" connect out to the lamp, for the "Neutral" just parallel to the Neutral wire. Any problem else?
