1/2 Mile Supplemental Hosmart Driveway Alarm Sensor (1 Tan Sensor only)

Brilliant! What didn’t I buy this years ago??
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.

Bit of a faff to set up but works well
I live up a farm track so have set this up at the gateway to let me know when someone arrives. The motion detector is about 25′ from the receiver (which I’ve plugged in but could be run on batteries and is positioned on a windowsill facing the detector) and so far everything seems to be working well and I’ve had far fewer false alarms than a cheaper model I’ve previously tried.It was a bit if a faff to set up as the design is really silly. The distance/sensitivity setting switches are inside the main body of the detector and if you decide you want to alter then once you have mounted it on a wall, you have to unscrew 4 screws on the mounting plate plus 4 fiddly screws on the detector housing to get at them. In a tricky set up like mine on an angle, with a slope, with pets and farm animals to avoid and test with, it took multiple tries to get the settings and position right and unscrewing it each time was frustrating and it worried me that eventually the plastic screw holes would break. Another really stupid design feature is the fact that to charge the detector I’ll have to take it down again to plug it in inside somewhere or drag out the extension cord to it. Again, a better design would have an easily removable rechargeable battery so the detector could be left in position. Can’t comment on the battery life for now but hope it lasts a good long time for this reason.Saying all that, I did eventually get it up and now the frustration of installation is somewhat forgotten, it is working well so on balance it was worth the extra money. The cheaper model (that was about £15) constantly went off when branches moved in the wind, the sun heated up things in front of it or animals passed it but this one has better sensitivity and distance options so has only had one false alarm so far and accurately warns me when a vehicle or person arrives. The brown housing is unobtrusive and blends well on a fence post and the alarm although a bit tinny is loud enough to hear in the next room but is not too annoying.

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.

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).
