Review on 🔒 Enhanced Security Enabled by Contact Sensor 858176004069 by Ham Channell

iSmartAlarm is a good investment for anyone looking to improve their home security at an affordable price. In addition, there are no monthly fees. After installing the alarm system, I needed another door contact. This fits the bill. It was easy to connect to the existing system. The two patches provided made it easy to install where I needed it. Even if the door frame is twisted slightly by the overmolding, the sensor works perfectly. The iSmartAlarm app notifies you when you need to replace the battery. Even though it's been over a year since I had to do this. Generally a quality product for the money.
