CPVAN Indoor 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)

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.

This is great. It’s protecting my shed very well. So easy to use and a great price.

Basic but pretty good, simple to set up, plenty loud enough.

Excellent alarm once set up correctly to pick up movement, so loud in high volume setting, well worth the money.

Brilliant product

Broke after 6 months of use, don't waste your money it won't last the year. Cheap plastic product no value

Loud but it's a bit of a fiddle to turn it on and off. Too many options. I wish it only had options on and off instead of too many buttons

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
