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)

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

Loud, uses AA batteries. Sturdy unit. Works for us. The only issue is the remote it’s very small and easy to loose, so be careful with it.

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.

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.

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

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.

When i recieved this i started by opening the battery compartment by removing the screw. The screw was not tight and just rotated round and round. the hole it screws into in the main body seemed oversize. They supply 3 cheap AA batteries so to prevent then leaking i replaced with duracell of my own. Screwing the battery cover back on was difficult as the screw would not tightenand just went round and round as before. - and no i didnt overtighten.. When i fitted the unit to the wall and rotated the bracket the main sensor and its U bracket fell off the footplate and hit the wooden floor of my shed. I pushed it back in and positioned it. It seemed to work fine when i tested it. The thing to remember with this type of sensor is a tea leaf can just rip it off the wall and smash it on the ground and probally stop it within 15 seconds, as its not that robust. But i have a shed door alarm too so hopefully things will be OK. I wish they did one that triggered a remote speaker so i could have this by the bed in case someone broke in during the night as if you are on the other side of the hose you might not hear it.
