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,

Very well made yes the housing is plastic but NOT cheap plastic simple to operate even if u have no instructions/manual is supplied however in various languages EXTREMLEY LOUD SIREN WHHICH U CAN HERE OVER 100FT AWAY Motion detection awesome no false alarms at all In fact i will be purchasing another 3 for my various out buildings One thing is it possibile to buy extra alarms for this brilliant prodct

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.

Very happy with these motion sensor alarms. They are very loud when activated which is ideal. Value for money. Good quality and discreet.

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

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.

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 the second set of these I’ve had, I put the first ones breaking / stopping working down to bad luck, but this second pair have also only lasted a year and a half. Same as the first set. If they were more reliable they’d be great as really effective and easy to operate
