The signal is faster and more stable. Placing the connected amplifier between the detector and the central unit can help effectively improve signal strength. Strong signal capability through walls without "dead" zones. The wireless signal transmitted by the auxiliary detector passes through the wall, and the amplifier is added depending on the specific environment to eliminate signal "dead" zones. Large coverage up to 500 meters. The multi-arc signal covers corners where signal is required, helping to extend the signal sent by the signal detector, so the central unit receives it normally. Removable antenna. Install the antenna to increase the reception and transmission distance of the signal amplifier.
