?Reliable Range - Communication range of up to 100m/328ft (the distance from the sensors to the receiver/alarm/chime) and detection range of the infrared sensor of approximately 5-8m/16-26ft to keep you informed and safe.
?User-Friendly - The alarm in the receiver has a ring volume up to 100dB, 3 mode choices (Sound/LED Flash/Sound and LED Flash) and 3 alert choices (High Volume Chime/Low Volume Chime/Alarm)
?Dependable Technology - Our sensor uses a state-of-the-art passive-infrared (PIR) to detect any movement within the detection zone. Perfect for long or hidden driveways to allow you just a little extra warning before guests (or intruders) arrive.
?Expandable - If you have more than one driveway or area you would like to monitor, you can expand this system with multiple sensors and receivers
?Power Supply - Both 3 x 1.5V type C batteries and the AC power adapter (not included) can be used for the receiver, but don't use them simultaneously in case the host would be burned
