The AX-260/330PLUS series is designed for reliability detection in outdoor medium range areas. Its premium, durable construction provides you with long-term and reliable detection. The detector's automatic gain control (A.G.C.) circuit helps compensate for signal energy losses caused by fog or heavy rain, ensuring that the detector will still function with up to 99.5% of signal energy lost. To further ensure the probe's stability, it can also adjust the beam cut-off time and be set to reduce false positives caused by small animals or fast-moving objects. Frost proof shell design and lightning protection are also suitable for your installation in harsh environments.
