HOSMART 1/2 Mile Long Range Wireless Driveway Motion Alarm System Outdoor Weatherproof Motion Sensor & Detector (1 Base Receiver and 1 Tan Sensor)

I ordered the Hosmart 1/2 mile driveway alarm to cover our property - absolutely brilliant! Our house is at the end of a cul de sac with no footpaths around, so NO one needs to be here at night but us. If someone else is here at night, I want to know immediately, but I don't want THEM to know I've clocked them. The sensors cover all angles in or out to our house, car or on foot. I painted one sensor flat black with bumper paint (masking off the sensor window of course!) and mounted it at the far end of the cul de sac where it funnels down so I can pick up anyone well before they reach the house. I've only had these up a week and already clocked a yobbo with his hood up running full speed past us at midnight. He hopped over a nearby wall and hid for a few minutes before he scanned around and calmly walked away, looking at his phone. He had no idea I was aware of his presence. I can tell how fast someone is moving by the time interval between two of the sensors. Anyone faster than the postie is running. I've had zero false alarms thus far. Packaging and set up is very straightforward. The instructions are clearly written and simple. Amazing... TIME-SAVING TIP: Sensitivity and channel settings are on internal micro-switches, so set these first, then do a mock install to test for false alarms/sensitivity/position/channel tone etc before you do all the screws up tight and mount it for good. Otherwise, you will need to undo (per sensor) 4x wall bracket mount screws, 1x swivel screw, 4x small rubber casing plugs, then finally 4x casing screws to open up to adjust. Note: Plug in the small white two-pin connector inside the sensor unit for the 18650 battery before charging. They come unplugged for shipping and warehouse storage, otherwise they would stay on as there is no off switch for the sensors. Once it's plugged in, it's activated. Any sensors set to either Channels 1 or 2 WILL GENTLY BLINK RED at the unit outside when tripped. Sensors set to Channels 3 & 4 STAY DARK when tripped like nothing happened. The receiver inside will alert you to all of them however! That means if you don't want anyone to know they've been clocked, set those sensors to either channel 3 or 4 and the sensor will not give it's location away at night by blinking. If you want to let people know there's a certain level of active security present, then 1 & 2 will be noticeable if someone is looking in the direction of the sensor, but it's a slow flash and not particularly bright. PS you can set all or just certain groups of sensors to the same channel if you want, but the alarm tone will be the same for those on the same channel. No big deal if they are in the same area, you'll know which general area to look. A few observations: - ABS plastic build quality is good, but someone could knock one off these off the wall or disable it with one decent swipe unless protected in some kind of anti-vandal housing. They would still set it off though. - The clips for the plastic rain hoods are a bit fiddly and might come loose in a proper gale but so far, so good up to 50mph gusts and driving rain. A little silicone etc would perhaps fix them better if you are in a really windy area, but I wouldn't glue them on because they may need to come off to adjust settings, etc. - The receiver can run off 4 AA batteries (I just use rechargeables) or off mains via a USB charger. - The lowest alert volume on the receiver is NOT very quiet. It WILL startle you if asleep near the unit. I put two small squares of duct tape over the speak grille and it makes it a lot nicer at night. If you turn the receiver off and back on again, it DOES NOT remember your old volume setting and will default to full volume when it wakes up or is triggered again. Trust me, you will soon learn this. Some people complain about the alarm tones. They're fine with me. You probably won't be hearing them very often unless you've set yours up someplace with a lot of foot traffic and you won't mistake them for anything else. Anyway, these are great motion detectors, they offer real peace of mind if anyone is around your place day or night.

I wasn't impressed with the colour as I wanted my alarm to be completely invisible. So I repainted the sensors. Easily done. My alarm is set to notify us when someone is at our front gate 100 yards from the house and also the location where the visiters/intruders are on our property. What we found is that this device can protect with 4 sensors or it can protect 4 areas with multiple sensors which is how we use it. After one month of using this alarm it works perfectly in all weathers. We get very little in the way of false alarms and that can be a bird sitting on the sensor or a wild animal in front of it. But that is only because of where we have placed the sensor. The range we did a test and it was somewhere near that distance in line of sight. But what impressed us a lot more is that our first sensor at the gate has it's signal going through trees and bushes in full leaf. Then through a large timber insulated building with 10" thick walls. Then through a twin 12" thick concrete walled house with multiple 4" thick internal concrete walls to the back bedroom. A total distance of 100 yards plus. So far, very impressed. The colour I altered with a bit of green/brown paint. What you get with this product is not just a driveway alarm, but a great security alarm which can be used to track your intruders. It is ok being notified of a triggered alarm, but by careful placing of the sensors this system can alert you to threats and track their whereabouts on your property. If you use this system with live video or game/trail cameras. Intruders can be tracked and filmed and you alerted while seated in your house. The ability for the sensor signal to penetrate multiple dense solid objects/walls makes this system far superior to other similar products on the market that I have tried. UPDATE NEARLY 4 YEARS LATER: Still going strong. Sometimes in rainy weather people slip by, but 99% of the time all good and no faults. Having multiple sensors detects those who slip by. Battery life is at least 3 months between charges. A great product for once. A real improvement would be to upgrade the system. Have 8 or 10 sensors and different alarm tunes for each. UPDATE NEARLY 5 YEARS LATER: Still working great with the sensors detecting daily multiple times and charging needs doing about every 4 months. One of the best products I have ever purchased from Amazon.

Ich bin total zufrieden. Funktioniert vom Dachboden bis in den Keller eines 4 Stöckigen Hauses aus Stahlbeton. WLAN Router gibt schon nach 2 Stockwerken auf.

My experience with the motion sensor alarm has been overall positive, providing an additional layer of security and peace of mind. Here's why I find it effective: First and foremost, the ease of installation is commendable. Most motion sensor alarms are designed for straightforward setup, often requiring just a few steps. This simplicity makes it accessible for individuals without advanced technical skills, allowing for quick implementation in various settings. The sensitivity of the motion sensor is a key feature. The ability to detect motion within a specified range ensures comprehensive coverage, alerting you to any unexpected movement in the monitored area. This sensitivity can be adjusted in many models, allowing customization based on the specific needs of the user. The versatility of motion sensor alarms is noteworthy. They can be used in various settings, from home security to monitoring outdoor spaces or even as an alert for store owners. This adaptability adds to the value of the device, making it a versatile tool for enhancing security. The wireless nature of many motion sensor alarms contributes to flexibility in placement. Without the need for extensive wiring, these alarms can be strategically positioned in different areas, offering a wider range of coverage without the constraints of wired alternatives. The alarm's immediate response to motion is a crucial aspect of its effectiveness. The loud and attention-grabbing sound serves as a deterrent to potential intruders and notifies occupants of the monitored space, allowing for swift action if necessary. Battery life is another positive point. Many motion sensor alarms are designed to be energy-efficient, ensuring prolonged use without frequent battery replacements. This reliability is essential for maintaining continuous security coverage. While the effectiveness of a motion sensor alarm is clear, it's important to note that false alarms can occur. Factors such as pets, moving shadows, or even environmental changes may trigger the sensor. However, many modern models come with features to minimize false alarms, such as pet-immune settings or adjustable sensitivity levels. In conclusion, the motion sensor alarm is a valuable addition to any security system. Its ease of installation, sensitivity, versatility, wireless design, immediate response, and energy efficiency make it a practical and effective tool for enhancing security in various settings.

Sensor werkt degelijk , bereik is uitstekend (getest op meer dan 100meter) maar beschrijving van het toestel klopt niet. Bereik van de sensor is beperkt regelbaar (2 posities i.p.v. 4) en de batterij is geen meegeleverde 18650 batterij maar 4 AA batterijen zijn noodzakelijk (niet meegeleverd).

Our previous detector was damaged by hail. I was happy to find an exact replacement. The only problem we found with both sensors is that it does emit a totally different alarm that what it was set to at times. This alarm does not indicate that someone or something has entered so you learn to distinguish the two sounds. The only thing we conclude that may set it off is weather conditions, ex.- fog, humidity, sun @ certain times of the day!

works great, love it. We live in the country and feel safer knowing when someone comes in the driveway
