Wireless video intercoms have played a major role in the spread of this technology. The absence of wires, along with the battery-powered search function for the outdoor unit, has greatly simplified installation. You no longer need to be a computer engineer to install your wireless video intercom.

Unlike other wired video intercoms whose range does not exceed 120 meters, this wireless intercom allows you to double the distance between the outdoor unit and the monitor, but only in open field conditions. Be aware that the range is drastically reduced if you have concrete walls that block the wireless system's radio waves.

The Lesli monitor's most significant advantage is its internal rechargeable battery, offering 2 hours of operating time and 6 hours of standby time. Ensure the monitor's temperature does not exceed 40°C or fall below 10°C.

It also includes a terminal block for connecting the gate opener and another terminal block for connecting the electric strike or lock.
