• ✅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

I think this is now my third set that I have bought now. I love them! Mainly use them at work at care facility’s for elderly and at risk youth. I love how their portable and can go in my work bag to wherever I go. Doesn’t matter what kind of building that I am in there’s always that one corner of the facility or a client that needs that extra level of caution and awareness. just having a blinking light as a alarm is perfect. I will continue to buy them amazing gems of tech. There very durable, when working with at risk youth; them have been kicked, and throw at me numerous times and remain in one piece. Only thing is I wish they were a bit Easter to program for use of four sensors to one receiver and if I could have more synchronized together I would.
