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)

Amazing product, works really well, no let down 👍. Saved me a lot of money. Bought 2, one for the middle of the camper and one for the front able to sensor sides and the back of the camper. Works perfect and it is really loud. Made up,

It proved simple to set up. The installation was spoiled by the head of a screw snapping off as it was fitted. The screws are a light alloy and totally unsuitable. I suggest stronger versions. The remote can have a battery change unlike a earlier review suggested. In all, it is very good. You might need earplugs when testing. I am happy to recommend both product and seller.

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 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.

So it’s a good alarm but I honestly hate the arming/SOS process, the remote controller is so sensitive it will activate the SOS when just in my pocket meaning the alarm blares out at full volume and when it’s right in front of you in a van it gets to be very annoying. The unit seems to have a few volume modes too and it’s very easy to knock it to a feeble low volume mode rendering the alarm basically useless. Mixed bag overall it does a basic job but the controller buttons are too sensitive.

Purchased a few -alarms all useless then I purchased this C PVAN motion sensor alarm, & could not believe how good this item is, easily set up, & adjusted. Once armed the capability is unbelievable would not want to be within the area when the 120dcb is siren is blasting Only negative is the remote, the padlock icon is hard to see for On & Off. Otherwise excellent Great Value & works out of box Instruction manual Highly Recommended

I find this to be good sound like a car alarm it has a fob like a car you could use it in any part of your house really.

This has worked pretty well over time, but the mounting system is really flimsy and doesn't hold the alarm very securely. I have bought three of these and one stopped working, but my main issue is with securing it. I will look for a better alarm which has a more secure fitting as it is high up on a rafter and is difficult to reach. Also, the batteries don't last that long. I suppose that you get what you pay for.
