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)

It's loud - so that's good. Easy to use - that's good too. Remote works from about 20 feet - that's excellent. For the price, it's just ridiculous value.

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

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.

Great little alarm. this is my second one i have bought and they are very load and work well. only down side to this product is the remote control, there is no button guard/cover and when in your pocket even a smalL coin can activate it but apart from that its a great alarm .............UPDATE this alarm stopped working after a few weeks and wont detect movement. I WAS ISSUED WITH A REPLACEMENT ALARM AS SOON AS I CONTACTED THE COMPANY AND IT ARRIVED RAPIDLY. NOW ALL IS WELL. FANTASTIC CUSTOMER SERVICE, FROM A COMPANY THAT CARES..

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.

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.

I bought this alarm as a replacement for one that had malfunctioned. Out of the box I thought it may be too quiet as my previous faulty one had a repeater siren also but was pleasantly surprised how loud it was once I had fitted the batteries. I have it free standing on a shelf at the rear of my hut where I keep my bike and it blends in very well amongst the cans alongside it. A little niggle with the remote is that is all black and at night it is hard to see which button of the four you are pressing. Apart from that the sensing range of both remote and alarm are quite good. Overall I would definitely give this alarm 4.9 out of five. Update! my alarm suddenly stopped working. I emailed CPVans support who answered within 24hrs saying they would replace the unit. While I was waiting for the new one they did ask that I perform some checks on my old one but to no avail. The new alarm arrived today and is working perfectly. Faultless and polite customer support so 5 stars for them.

Good product.
