Mengshen Motion Sensor Alarm, Wireless Doorbell Alert for Front Door/ Door Entry/ Driveway/ Home Shop Visitors/ Mailbox, Home Security System Kit with 1 Sensor and 2 Receiver - YBQ041

Fantastic kit! great price and works better than expected, my only regret is not buying 2 or 3 kits because of how versatile they are. Example one set watching side entry with audible alert for security, another set for in the porch watching for deliveries, guests and post. Pro tip that I discovered, if you have a mirror, you can expand the sensor range and angle.

We didn’t want a cat flap, so we put the sensor outside when we let the cat out. Bell rings when it senses the cat at the back door. Accidentally left the sensor out all night in a rainstorm and still works ok. Loads of ringtones to choose from.

Works well value for money

The Mengshen motion sensor alarm is powered by 3 AA batteries for each of the 2 receivers and 3 AAA batteries for the transmitter that are not included in the kit. The photos on Amazon show the transmitter in various locations including a sheltered outdoor location but the instruction sheet clearly states that the device is for indoor use only.I’ve set the device up in doorbell mode and the signal range is excellent and there have been no false alarms so far. There are a wide range of tones and around 35 melodies but the simple ding-dong and very bright flashing LED light is the best option in my opinion.There are a small number of videos on YouTube that demonstrate the device setup and melodies so it may be worth checking them out before purchase saving you some time and inconvenience of returning the product if unsuitable.Purchased from Lanke Direct vía Amazon with free shipping.Recommended.

Use now, feel general, sometimes infrared sensor good, sometimes infrared sensor failure. But it's pretty simple to install.

My pond fish were being eaten by a predator and this brilliant motion sensor has given me peace of mind and saved my pond fish. Its so easy to set up and the alarm is loud and does the job. Love it

I bought the product to use it as an alarm but the remote control that came with it did not pare with thr receiver.Thus I cannot use it, totally wasted money, I will return it

Fantastic product, this replaces my old one, great detection, having more than one sensor is fantastic and I love that I can move the sound receiver to what ever treatment room in.As I’m in a beauty salon and work alone this is ideal for me, it has a number of welcoming tunes and also two light ones one that changes colour ideal if I’m in a massage and don’t want to disturb my client, so there is no noise but still alerts me 😀
