CPVANIndoor Motion Sensor Alarm with Siren, Wireless Infrared DIY PIR Motion Detector Burglar Alarm System, Battery Operated, 125dB Adjustable, Remote Control for Home/Garage/Van/Shed/Shop. (Black)

A really great unit it's so easy to connect the window and door sensors and the sensor on the unit is really affective,, it's ear piercing loud,, so so loud,, I have it on number 1 of 5 volumes,, it's well worth the money

I've already got 2 of the older version of this alarm which I am still using and very pleased with.This new version has a number of improvements over the older version - which are most welcome. It takes 3 AA batteries opposed the 3 AAA in the old version - which I think means it will last quite a bit longer on a set of batteries but they've not run out yet in the 2 weeks I've been using it. I can't be sure but the alarm also seems quite a bit louder than the old version.I've also noted that you have the option to power the alarm using a USB cable - by plugging it into the sockets in the back. This gives you the flexibility to run it from mains or from a power bank for extra long run times..The fob on this version seems to be a little sturdier than the old version - which is a welcome improvement.I use the fob to disable the alarm from quite a distance - which is handy.Like the old version you get a little bracket to mount the alarm and you can use the provided screws or sticky pad to attach the bracket where you want it. The alarm can tilt and rotate in the bracket - so you can point the PIR sensor where you need it - for example, I've mounted mine around waist height so I've had to tilt the sensor back slightly to it covers a good distance in front of the alarm.Overall I would highly recommend this alarm for securing small spaces - especially sheds/caravans/motorhomes. It's simple to setup and when triggered is very loud.

The device itself is fantastic. Sturdy, very loud, sensitive - does everything I want it to.You can set it to either chime once when it detects movement, or sound the alarm.There are also two volume levels. One is medium-to-loud, the other is ear piercing loud, and would definitely startle intruders.Only issue I forsee is the remote - it's really handy, easy to use, and you can use it from quite some distance. However, there's no way to replace the battery in the remote control once it dies (unlike the device itself) - so, once the battery in the remote goes, you'd have to go without, or, order a new remote. Bit of a design flaw, hence 4 stars.

I’ve bought 2 of these alarms. They’re great. I also have the vibration alarms on the van as a first defence. But these ones act as back ups in case the thieves actually enter the van.They work fine.Alarms are the only way to protect your tools I think. Locks and cages can all be opened and broken. Cameras don’t work on covered faces. Alarms deter and alarm us to the thieves and we have at least a chance to get out and sort the problem.

Easy to set up and the siren is INCREDIBLY loud. Hoping that if there’s ever a break in at my home, this will be enough to frighten them off.

Sort of OK but the battery life is poor only lasts about 3 months. I have changed batteries in both units twice in 6 months. I would not recommend these alarms.

Good, loud alarm, has many uses, put mine in the shed

I bought this to protect the contents of a van. It ticks all the boxes. Unfortunately twice now within 24hours it randomly starts to whine inexplicably after a period of being armed. The whining is noticeably loud. I hope the manufacturer can resolve this for me?
