tiiweeA2 PIR Motion Sensor Anti-Burglar Alarm System with Remote Control - 120 dB Siren - Expandable - Alert and Chime Mode for House Garage Shed Shop Home Security - 2 Year Warranty

I don't say this often but this has got to be the best Van alarm ever! yes Van alarm!As it is powered by batteries I decided i needed a alarm that i could move from van to van.the fact you can change it to a single bleep to show someone is next to your van when the doors are open is also a great feature.I have 1 siren with PIR and 1 PIR. what i did was installed the siren with PIR to inside of my side door and the other PIR to the inside of my rear doors. Job done. took about 5 min to install and bang! my van is protected.This product provides more then just home security.

The alarm is OK. Works as advertised and guards the caravan.The remote, however is very vulnerable to knocks and falls. There is LOTS of free space inside and if it falls on the floor from table level or above the battery inside gets displaced out of its holder. As a result it stops working.

We brought this for my husbands van after catching thieves trying to break in to it. Last time we weren’t so lucky and had been searching for a easy to install alarm, which we were not having any luck.It has been in the back of the van for a few days, remote works through all the metal and the racking. It is situated by the bulk head so covers the side doors really well also. We can hear it perfectly upstairs. It’s actually louder than my factory fitted car alarm. The siren is a perfect deterrent if needed.We are getting the window ones to cover the doors in the cab. Would highly recommend this to anyone for peace of mind with a van.

wonderful at first nice and loud but after 2 months stopped working and now can't get it to work properly I have 2 of these so far the other one still works but for how long I don't know

This is a tremendous, and cheap alarm system and an absolutely brilliant, and extremely portable way of alarming anything, anywhere at any time, and alternative to a ludicrous inbuilt home alarm system. It's as simple as - put batteries in, switch it on, then arm it. The motion detection is absolutely perfect and 100 percent accurate. Also, if you get the expansion units, you can very simply link them to this host unit, and have however many you like, in however many rooms or positions you like, all communicating with this base. Want to alarm your garage? Stick a unit in there. Want to alarm your garden shed? Stick a unit in there. Going away on holiday? Take them all with you. arm your Caravan or chalet. Hell, arm your car if you need to! You need no wifi, no 4G, no 5G, no ridiculous set up. It's as simple as link your units, and then one button press to arm and disarm the whole lot. Perfect totally portable and reliable peace of mind. Awesome.

Battery life very short - can rechargeable batteries be used?

I like this. I have it in my garden studio which is also my work room with quite a lot of expensive equipment in it. I was concerned about security so bought this. It's an affordable, VERY loud alarm which can give a long intruder sound or a beep beep when the door opens (ideal for a shop where someone may be working out the back to notify them someone's come in). Its easy to arm and disarm, I have the small keypad on my key fob. I would recommend.

Batteries (duracel) only lasting about 3 to 4 weeks. That is only problem I have with it. Don't know if there all like it or I have a dodgy one.
