Wireless PIR Motion Sensor Detector Home Store Welcome Buzzer Monitor Commercial Door Entry Security Alert for Business Mailbox, Caregiver Reminder for Elderly (1 Sensor & 2 Doorbell)

This is a nice little sensor doorbell kit. It says here that its a Motion sensor device, however, description leaflet inside the box tells that it senses a change in the temperature of the environment (e.g. a human entering and therefore it senses human temperature) and sends a signal to the receiver which then rings the bell. There are quite a few fancy ringtones to choose from too.In terms of its use, its pretty accurate. It senses almost every time and successfully sends the signal to alert. It has a very decent range too. In the box you get one sensor only but with two receiver bells. So far I am only using one receiver bell and satisfied with its result.The kit is also well made and looks good quality. Luckily, in addition to using a lot of batteries (3x AAA inside the sensor and 3x AA inside each receiver bell) you can also charge these via the USB charging cable. The sensor should ideally be mounted at the entrance area whereas you have the option to either mount the receiver bells on a wall or just keep those on your desk using the stands provided. All in all, satisfied with this starter kit and would rate these as a 5 Stars. For the price this kit is also good value for money.

The ease of installation and setup makes it a breeze to use, and the wireless design ensures flexibility in placement. I like the versatility of the system, as it not only serves as a security alert for commercial door entry but also doubles as a caregiver reminder for the elderly. The inclusion of two doorbells adds extra convenience for monitoring multiple entry points. Plus, the reliability of the motion sensor and the responsiveness of the alert system provide peace of mind knowing that I'm always aware of any activity.
