About this item
  • 【900ft Wireless Motion Sensor Alarm】Infrared sensor detects motion and sends a signal to the receiver. The receiver sounds when the motion sensor is triggered by someone crossing your gate, driveway, garden, porch, house, shed, offices, walkways, shops, etc. Large working range up to 900 ft (no obstacles) to fully cover your property and security.
  • 【Expandable Home Alarm System】The motion sensor doorbell includes a motion sensor and receiver, up to 32 sensors, doorbells, and receivers can be expanded to protect your property and security. Good as a doorbell alarm for home security, also a door chime for business when entering, care reminder for the elderly.
  • 【17 Bell Rings & 5 Volume Levels & Silent Mode】Motion detector receiver with 5 volume levels (including mute) from 0-96 dB and visual alarm via LED light (red, green, blue, white) when ringing. Each sensor and transmitter of your home security system can be programmed to have a different ringtone, in mute mode, only the LED flashes without a chime.
  • 【Two types of charging】Enjoy flexibility with two charging methods for the motion sensor doorbell, including battery operation for convenience or USB charging for continuous power supply. The receiver uses 3 x AA alkaline batteries and the sensor uses 3 x AAA alkaline batteries. It is recommended to replace the battery every 5-7 months, based on 30 uses per day.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
