4VWIN DIY PIR Motion Sensor for Wireless Driveway Alert System.

Easy to set up

Mixed emotions - I recently had a container shed robbery & the same night my outdoor camera went off line missing all the action, so I ordered the receiver & sensor as a package for £9.99. I also bought a brand new battery. The receiver works fantastic. Its a very robust unit with a very loud alarm. The sensor is more delicate compared to the receiver & I wish it was the other way round. My new battery didn't last 2 minutes & realized that I also needed to buy a 9v battery charger because standard chargers don't facilitate a 9v battery - so, more expense. When changing the battery I found it really difficult not to snap the very thin wiring from the circuit board but inevitably it happened. Then I decided to buy a soldering iron to repair it ( more expense) but didn't do it. I burnt calories off procrastinating whether to repair the broken or buy new because a sensor by itself was as costly as the receiver & sensor as a package + wondering if a new one would break as well while still waiting for my camera to go back online, which it didn't.In the end I just bought another sensor. To top that stress I had to return THREE defective battery chargers, 2 from Amazon & one from ebay. My next stress was where to place the sensor where theives couldn't notice the red light & try to steel it but I eventually found a suitable place for it and secured it. I also bought an extra 9v battery, expecting the cold weather to wear the current one down but so far it hasn't. I am lost witout the reliability of my camera but knowing the sensor does successfully trigger the alarm is reassurring. I have it next to me at night & if my son jumps over the fence the indoor receiver is triggered nice & loud.I WOULD prefer a more robust sensor with stronger wiring. But so far its working good. I intend to repair/solder the first sensor & place it in another part of the garden.To further weatherproof it, I enclosed it in one of those black microwaveable throw away containers. SO, after buying a Sensor/Receiver package + a Replacement Sensor, 3 replacement batteries +3 x9v Battery Chargers I would have spent less buying more expensive.Trial & error.This will do for now !Good luck !

Work perfect for me do everything I want them to

It’s a 50 50 gamble with them, sometimes work sometimes don’t. Also battery’s don’t come included.

It doesn't work,red sensor light stays on and drains battery.

good

Works well

Mycket dålig räckvidd.

Funzionamento perfetto

Es un producte senzill però eficaç. Els únics problemes són que si en tens més d'un mai no saps quin és el que sona perque no hi ha possibilitat de discriminar els sons de cadascun.Un altre problema és que si algun veí te la mateixa freqüència el receptor es torna boig.No obstant això, n'estic satisfet.

J'ai ajouté cet appareil au modèle 1byone et c'est compatible. Donc la console gère 3 détecteurs. Me permet de compléter la protection par détection aux portes d'entrée sur mon terrain.

Tut was er soll, auch wenn es sehr preiswert ist, Reichweite durch eine Wand um 30m, es sollte an der Rückseite kein Metall sein, ein Paar cm Abstand reichen aber
