A:Answer Hi CuriousGeorge,
Thanks for reaching out.
Nine feet (three meters) off the ground is the optimal height to get the best range for the motion detector. With the motion detector parallel to the ground, Floodlight Cam optimized for detecting human-sized objects up to 30 feet (10 meters) away. Additionally, In order to support its robust array of features, Floodlight Cam needs to be hardwired into a standard junction box. As Floodlight Cam requires a junction box as well as wiring up live wires, it's highly recommended you hire a licensed electrician to install Floodlight Cam.
Thanks,
