HTZSAFE Wireless Door/Window Magnetic Sensor Alarm-600 Feet Long Wireless Transmission Range-35 Classic Melodies Optional,4 Volume Levels & LED Flash-Home/Business DIY Burglar Alert Security System

Added another ringer to my existing ringer that I have had for 2 years. Use as a driveway monitor but needed a notifier when I am in the basement. The door alarm is an extra bonus as I now know when someone enters the house while I am in my basement. Great, easy setup and use. Just plug in, follow directions in manual and you have a good inexpensive alarm system.

Era lo que yo necesitaba

We paired this with a motion sensor and it works great. We really got it just because we wanted an extra bell in te basement so we could tell if a package was arriving while we were downstairs. Works great for that, but also nice to have a door sensor in the basement for when we're upstairs.

This product works great for the purpose we bought it! I highly recommend if you need a door alarm for whatever reason, you purchase this one. We have two levels and the alarm itself is on the 2nd floor and the receiver is on the 1st floor and it works perfectly! Really like the fact that you can change the tone/tune of the alarm.

Ok. I do love this product. You have to communicate with tech through email, but they are on top of it. Answering immediately.If you have one Sensor and one Receiver, this is a solid product. It works. But we could not add another sensor. Believe me, they worked their butts off trying to walk me through it.It’s all good. There is one tune that is perfect. Right length and volume. It is so nice to know when someone comes up my drive. And this hides very well. In a receptacle beside a sofa. Don’t even notice it.
