4VWIN Home Security Wireless Driveway Alert 1 Receiver and 3 PIR Motion Sensor Detector Infrared Alert System Kit

I couldn't be more pleased with its performance! This kit comes with one receiver and three PIR motion sensor detectors, providing excellent coverage for my driveway and front yard.The installation was a breeze—setting up the sensors took just a few minutes, and the wireless connection worked flawlessly. The sensors are highly sensitive, detecting movement from a good distance away, which gives me peace of mind knowing that I’ll be alerted to any activity outside my home.The receiver has a clear and loud chime that can be heard throughout the house, making it impossible to miss an alert. I love that I can adjust the volume and choose from different chime tones to suit my preference.The build quality of both the sensors and the receiver is impressive; they feel sturdy and well-made, which is essential for outdoor equipment. Plus, the infrared technology ensures reliable performance even at night.Overall, this system has significantly enhanced my home security, and I highly recommend it to anyone looking for an affordable and effective driveway alert solution.

Sometimes the simplest solutions are best. Our garden is invaded at night by fallow deer which damage a wide variety of plants and make vegetable gardening impossible. We have cameras but watching with them all night was not an option. We installed these passive infrared (PIR) detectors at strategic points to alert us to our intruders with antlers. The PIRs detect up to 5 or 6 metres away and communicate to the base station alarm over a distance of 12-15m, which significantly better than Bluetooth and WiFi systems. This matters because we are guarding nearly half an acre of garden and the deer are good at sneaking into the far corners. The only limitation is that all the PIRs trigger the same alarm response so which one was triggered is not known. Not a problem though, because the deer are pretty hard to miss once we know they’ve arrived!We actually have two sets of alarms, i.e. two base units and their PIRs. Being ‘dumb’ devices they are uncomplicated, working seamlessly with each other. Assembly is easy, C batteries in the base units with an optional socket for powering with a plug in power unit, PP3 batteries for the PIRs. We have been running these devices for a few weeks on the batteries with no replacements so far. Wall mounting screws are supplied and tiny screws for the battery panels (one kit lacked these but I had plenty in the shed anyway).

After an attempted burglary in June we set about improving the security of our rural home. CCTV, new snap/bump/pick proof euro cylinder locks and most importantly a system for alerting us if someone was wandering around our property.Items arrive well packed and are a doddle to set up, just install the batteries (you'll need a watch size screwdriver), pop a screw in the surface you want to mount the PIR to, turn on the receiver and boom it works.I bought a receiver and two sensors initially but now have 9 sensors around the house running to 3 receivers to make sure that one picks up the signal. In practice however, the range is very impressive. There is signal degradation through walls etc, but from the window in our bedroom to our gate, around 60 meters, the sensor picks it up most of the time.Alarm volume is adjustable to high and low, high is loud enough to wake you up if you're in the same room and low is just right to alert you in the day to visitors.However, there are some bad points. I've had many false alarms from two of the sensors which in the end I discarded, and finding which sensors they were was a long process (removing batteries from others to test one by one).With regards to battery life, it's actually pretty good you'd probably get 4 months on the sensors and 1 year plus on the receiver with decent batteries.Note, if the light stays on on a sensor, its low on batteries.After 6 months, it should be noted the battery cover screws have started to corrode and perhaps a stainless steel screw would be more appropriate.I noticed there are two type of PIR, some with the LED mounted behind the plastic moulding and some with LED mounted through the plastic moulding. Which is interesting.Of the four receivers I have one arrived with a faulty siren, but to be honest I only needed three so it was no great shakes.It would be nice if 4vwin sold replacement sensors on their own and I'll ask the question here.There is no real waterproofing on the mount plate or the battery cover. I'm not sure if that is what caused the faults with the 2 PIR's or not but it is worth noting.They are a bright white and quite obvious, to make them more camouflaged I've pained a few in estate green paint (which has since washed off a bit but still works). This hasn't affected the range but when hung on a tree somewhere you can barely see them. Perhaps 4vwin could produce a woodland/garden version with a mix of green/brown?When placing your sensors it took a few attempts to get it right as we're covering a huge open rural house but I think we are about there now. Plan your intruder entry points, cover doors, patios, gates etc.I'd love to give this product 5 stars but I just cant. Failing sensors, faulty receiver alarm on delivery, rusting battery screws dropped me down one star BUT all that said a VALUABLE piece of home security at an affordable price.

This is a perfect detector, well pleased

Not bad but a couple did not work

Battery connections are rusty, screws for battery covers missing.Can't return because of Covid-19 - only options to return are to drop it off at a collection centre - which I can't do.Waste of money.

Bought this to protect the contents of a large canvas garage that has zip up doors. Have placed one motion sensor at the back of the space and the receiver/alarm in the house. It's worked well on testing it, even picks up me if I'm outside the canvas, obviously it wouldn't if it was through brick or wood. For the price, can't fault it. Would have been even better if it had a keyfob to disable it while you're working in the same space as the sensor.

Use these in the shed and garage and they detect motion very well and raise the alarm. So quick and easy to set up, really quick fix for security. Good value for money.

Perfecto y súper recomendable. Cada sensor lleva pila de 9v pero bueno, aguantan muuuucho "tute". Totalmente recomendable!!!!

helt nöjd

Qualités : Repère très bien les mouvements, aucune erreur faite, avec un assez large champ. Je dirais 30-45° à gauche et à droite. Je n'ai pas encore fait le test avec le champ de repérage vers le haut ou le bas. Vous avez un bloc plus gros que les autres que vous pouvez gardez avec vous et bouger si besoin et laisser vos 3 autres détecteurs faire le boulot de repérage. Les satellites repèrent un mouvement et ça sonne sur le gros bloc que vous avez conservé avec vous.Défauts : le son émis n'est pas violent (même en high). Attention il n'est pas fait pour faire fuir un voleur avec un son énorme mais juste à vous prévenir, vous réveiller la nuit en cas d'intrusion.Bilan : Satisfait de cet achat. Personnellement, j'en place un caché avant que le potentiel intrus puisse accéder aux chambres. J'ai placé les autres face aux fenêtres qui ne comportent pas de volets. Vous pouvez mettre aussi devant la porte et accès sensibles. Il y a un bouton OFF/low/high (son bas et son plus fort réglables).

Non ho preso questi sensori come allarme anche se ovviamente la loro funzione principale sarebbe quella.Ho preso questi sensori da mettere davanti ai balconi, più che altro per i bambini, ho le ringhiere facilmente scavalcabili ed ho paura che in un attimo di distrazione i nipoti possano arrampicarsi quindi uso questo sistema per essere avvertita nel caso ci sia passaggio verso il balcone.Sono pratichi perché non hanno fili funzionano in wireless ed a batteria (una di quelle quadrate da 9v per il sensore e tre torce per il ricevitore).Io li sposto a seconda di cosa devo controllare quindi non sono neanche fissati al muro, appoggio il sensore per terra o dentro un vaso e trasmette tranquillamente il segnale da una parte all'altra della casa istantaneamente.Funzionano perfettamente e fanno esattamente quello per cui sono stati acquistati e quindi sono contentissima della scelta fatta, anche se questa volta con qualche consiglio in più perchè io non ci avevo proprio pensato a questa soluzione semplice ma... Tecnologica.
