Review: Prevented the theft of a motorbike. - 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 desertcart 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.

## Questions & Answers

**Q: What's the trick to get it to use the voice talking saying 'garage' instead of the melody?**
A: I don't know that voice is an option with this alarm,  only different melodies. I will say this seems to be an excellent product, mine has been in since Spring and still on the original batteries. Very reliable, no false alarms, works very well.

**Q: Are all receivers and transmitters operating on the same code?  Can I add a receiver at a later time?**
A: Hi there,
one sensor can be connected to unlimited receiversall the HTZSAFE receivers can work with all the HTZSAFE sensors.
Hope it helps and please email us at contact@saferhomee.com if any other questions.
Thank you!
HTZSAFE

**Q: Does the receiver have settings memory on loss of power ?**
A: We had a 10 hour outage and it was still paired..  There is a button battery inside the receiver and I would believe that is to keep the memory during loss of power.

**Q: can you plug in receiver indoors when monitors are outdoor use only**
A: I have two of these sensors. One is at the head of the driveway, roughly 100 yards away from the plugged in receiver in the house. The second is another 30 feet beyond the driveway sensor mounted inside my mailbox which is not visible from my house. Mailman opening the door sets off the chime and I get my mail before it can be stolen. 
HTZSAFE customer service is excellent too btw
