MeichoonSecurity System Motion Detector Doorbell, 1x Infrared Sensor, 1x Receiver, Wireless, 433 MHz, 8m Range, Battery Powered, Indoor/Outdoor Use, Q-YBQ04 Model

This motion sensor alarm set comes with instructions and mounting equipment. Both the sensors and the receiver take batteries (sensors take AAA and the receiver AA) but none are included. Each also has a micro-USB port which is good as I much prefer using USB power rather than batteries. In some locations cables won't be practical so it's useful to have the choice.The receiver can be set to a hello welcome message (there are a couple of languages) or doorbell/music - there are dozens of those to choose from. Alternatively you can have an alarm, either silent with just a flashing light or non-silent. The alarm at maximum volume is extremely loud so take care when setting it. There are lower volume settings thankfully.Build quality appears to be very good and the instructions are just about clear enough for setting the sensors. At home the sensor can be used as a doorbell, alarm or just a light. The sensors have pretty good range, so I'm using them to alert me to movement in the house after dark, I already have one similar sensor so these two are providing additional coverage.Overall I'm very happy with this motion sensor alarm set. It doesn't rely on wi-fi and works very well.

Good set of external presence detectors.These are good for adding in to a porchway to let you know someone is at the front door should they not use the doorbell, we have also added one inside our caravan that is on the drive so we know when someone enters it.The receiver is really loud at chiming however this can be turned down.having the option to run all off micro USB or batteries is a good feature as we do not need to plug the caravan on in.The option to mute the buzzer and have only flashing lights is also good for me due to working from home, it means i can be notified of movement when in a team's meeting but not be disturbed... extra bonus that it also flashes multi colour so you know it is not reflected light by mistake.This is worth the price due to its flexibility alone so 5 stars.

This motion sensor alarm works as expected. The receiver can get very loud if desired. There are a few different sounds to choose from as well.The receiver takes 3 AA batteries and each sensor takes 3 AAA batteries. Alternatively, each of the sensors and the receiver can also take power via a micro usb port.The sensors work very well and are reasonably sensitive. I recommend this for sure!

I was very upset with the tiny and unclear institutions but I found a YouTube video on how to set it up.Now that I have it set up it is working well.

Funziona perfettamente, soddisfatto

Un buen conjunto de detectores de presencia externos.Agregar uno a la puerta de entrada es excelente para saber que hay alguien en la puerta que no toca el timbre. También teníamos a alguien apostado en la caravana en la entrada para avisarnos si alguien entraba. Los auriculares hacen mucho ruido, pero puedes apagarlos. El hecho de que solo pueda funcionar con micro USB o baterías es una buena característica, ya que significa que no tienes que enchufarlo a tu caravana. También me gusta que puedo apagar el timbre y simplemente encender las luces. Porque cuando trabaja desde casa, puede recibir notificaciones de cada movimiento durante las reuniones del equipo. También parpadea en varios colores para que puedas asegurarte de que no haya reflejos de luz accidentales.

Ce kit de 2 détecteurs de mouvement avec son boitier alarme sans fil est pratique et permet de sécurisé sa maison devant et derrière (pour ceux qui ont des baies vitrés comme moi) ma baie vitré derrière dans mon terrain ne ferme à clef et on a facilement accès car tout les terrains de mes voisins sont mitoyen avec le mien donc n'importe qui peut avoir accès derrière chez moi donc je suis plus rassurer avec ce kit d'alarme et détecteur de mouvement.Seulement faut prévoir des piles.En bref, il fait ce qui est décrit dans la description même si moins fiable qu'une protection caméra.
