Driveway Sensor- Extra Wireless Weather Resistant Outdoor/Indoor Motion Sensor&Detector for HTZSAFE Alarms-1/2 Mile Wireless Transmission Range- 2 Adjustable Sensitivities, HB-T804

These were purchased to ADD to my existing system - it was cheaper to buy With the Receiver than buying 3 owl transmitters on their own. They did arrived paired to the receiver, as one would expect, BUT i needed to pair them with my existing receiver.. two units paired immediately without any problems. the third unit was a different story. initially it refused to pair. so i emailed the manufacturer. in the meantime i repeatedly tried to pair this last unit to my existing receiver. after about 20 attempts it decided it would pair together. However in doing so it changed all the tones of the units both new and existing. So i had to go round and re-set the tones - not a big issue, i just prefer different tones so i know which unit is being triggered and in which order "IF" more than one unit is triggered. Once paired i looked to mount them when i then came across one of the mounts was split - this was only noticed when trying to, mount the units The supplier came back to me about the pairing issue [which i had now resolved] the response initially was to resend the pairing instructions - as if i was an imbecile - i ignored this and replied advising that i had now managed to get it to pair and that upon mounting i noticed the mounting was split meaning the transmitter would not sit within the clip. They requested my Amazon order number which i duly supplied and a replacement was sent to me. so aside from that initial reply telling me how to pair the units - which i was fully conversant with anyway, Customer service was SPOT ON!!!! Provided the units are not mounted too low - in which case they can be triggered by cats, or dogs etc, - they are great for alerting me to unwanted guests [especially at 3 am in the morning -read on for more on that bit] so i now have two units covering my drive - one is out of sight close to the street, one one is at the bottom of the drive,. - i have two units covering my back garden - just in case anyone comes fence hoping and a 5th covered the side gate! [opposite side of the house to the drive] Do they work?? of course they do!!! We were woken up at 3am on the FIRST NIGHT that i had extended my system from 2 to 5 units!! 4 scum bags had set them off trying to gain access to a motorbike, i was out of bed and chasing them down the street in my slippers and PJ's [as was my son] As a result of these units the motor bike was untouched, chains and locks on the bike were untouched, we were alerted to the crooks and they were immediately thwarted. They had no idea we had been alerted to their presence until we appeared with a torrent of verbal abuse !! Had they reached the bike, they would have encountered a shed alarm at 120 or so Decibels!! YES, worth the cost, stopped us losing a nearly new motorbike, and prevented them even trying to cut the locks and chains off the bike. So we use them as a warning alarm of potential theft, and it works, they are great for monitoring your driveway anytime day or night. You can soon learn if your kids have slipped out the garden gate against your wishes and instructions. or if someone is approaching your front door before they get there. Not heavy on batteries either - each transmitter takes 3 AA batteries, i use rechargeable's and a set lasts for about 1 year - the receiver plugs into a mains socket My only gripe really is that some of the tones are too short and possibly not loud enough but there are 4 or 5 tones that are that bit longer and louder, which i feel you need, especially at 3 am in the morning!! [i think there were 4 volume levels - highest is best at night] It would also be good if it was possible to record your own tone as well. so a few tones not really suitable to alert you in the night but that aside - EXCELLENT!! i have had my original transmitter and receiver now for almost 2 years - this purchase was simply to expand the coverage of that original set. just a shame the police are not as quick to respond as we are.

Absolutely brilliant Everything that comes near them is alarms

Perfect item 5 stars

I was recently burgled whilst in my house - very scary!! So I wanted to detect intruders before they smash the windows. I bought 3 sensors - front, side & back of my house. Set up is easy following the YouTube video. I had a query as to whether the receiver would still remember the sensors if it was unplugged & moved around the house. The answer came back within 24 hours as promised & it was "yes". My only disappointment is that the dog bark tone, which I bought it for, is not loud enough to be heard outside the house & therefore the deterrent effect is not effective, other than one sensors being visible above the front door with the other 2 hidden.

Picks up delivery men etc before they got to the door, and any unexpected visitors

Very pleased working well, this replacement is good as you can buy extra sensors without having to buy a new base unit

Incomplete sensors (no backs nor mounts), complete ones do not work, seller not responding, address label to me has an eBay code in it despite fact I did not buy from eBay, return / supplier's address on box is a fish and chip shop. 2 Year guarantee? Really?!

I bought these 6 months ago and so have given them a good road test. They are superb and work exactly as described. They definitely give an extra level of security around your property at night.. I would not hesitate to recommend these to anyone . Easy install, easy setup.

Pas déçu, son correct et différent en fonction de l'endroit (au choix)

This is a wonderful product just for peace of mind. Very easy to set up and works for long distances, although I didn't test the very limit. Did have a few hiccups after a few weeks with one sensor - wasn't going to complain as the other ones worked but the company contacted me to make sure I was happy and so I asked for suggestions. They went above and beyond all expectations and if you're like me and don't like to return items or make a fuss, this is where to get this driveway alert and be assured that if anything isn't working properly, they will do their utmost to make sure you are satisfied. So very pleased with this purchase and even more so with their outstanding customer service.

Ottimi sensori nonostante siano elementari. Se durasse un po’ di più la suoneria una volta segnalato il movimento sarebbero veramente perfetti.

Na een week blijkt dat de batterijen van een van de drie uiltjes binnen een dag leeg zijn. Amazon verwijst me door naar de fabrikant welke niet reageert.

Ich verwende das Produkt bereits seit fast mehreren Monaten und bin begeistert. Ich war zunächst skeptisch, weil ich davon ausging, dass die Sensoren mit den Batterien unzuverlässig seien, von der Reichweite beschränkter, bzw. oft die Batterien gewechselt werden müssten, aber nichts von den Sorgen hat sich bewahrheitet. Ich habe zwei Sensoren nacheinander in meiner Einfahrt plaziert. Auf diese Weise kann ich erkennen, in welche Richtung sich ein Auto oder eine Person auf meiner Einfahrt bewegt. Und es klappte bislang absolut tadellos. Ich bin begeistert von diesem Produkt und ich bin jemand, der skeptisch und kritisch ist. Was ich mir allerdings noch wünschen würde wäre, wenn es noch mehr Auswahltöne für die Alarmierung geben würde oder man selbst Töne dafür aufnehmen könnte.
