Voice Alert Weatherproof VA6000T Wireless Motion Sensor and Audio Transmitter 2-Piece Pack Battery Operated

I got these to go with Voice Alert System-6 Home/driveway Alarm. Gives extra notification with more than one sensor. Be sure to program the inside of each sensor to be different than others. for example; one may say 1, 1. Put another at 2, 2, etc....If you don't, each sensor will say the same thing as the others.Follow instructions to the letter. Not hard. Install under eave of house/porch, etc...to keep rain off....I haven't had mine long enough to know how long they will last. They pick up at least 30 feet away, I think even further than that! And they have a broad view, not just a zeroed in type. They are very similar to motion sensors on regular burglar alarms - which we also have (inside our house/garage, etc)

Very good product. I use it to monitor a somewhat disabled adult from her room upstairs to my home office in the basement. I can alwaysbe aware of what she is doing. Only disadvantage, I can hear her TV more than I would like.

Had the base unit for over 8 years. These last about 3 years outdoors before the circuitry takes a "dump". Honestly, I don't mind replacing them because they do function perfectly otherwise.

I have had this Voice Alert System for 3 years. These sensors pick up movement over 30 feet away and have a wide angle. The whole system is exactly what I was looking for.

they work great, just bought two more

Had some difficulty setting up the different locations to be monitored, still get some false alarms on a couple of the locations but all in all it's was okay!

So far these are great! Once you get them dialed in, they are awesome.
