Battery Powered GSM Alarm, Perfect for Sheds - Caravans - Garages, 130 Decibel Siren

I am very pleased with the alarm, simple to use but very secure

There are two versions advertised. although they are basically the same item. One states 'no sim thank you' - although they mean 'no sim supplied', for £79.95. They offer a roaming sim card at £12 and the other 'version' is £91.94, so you would think this one has a sim card with it, but no! It has a second remote control! Silly me! I had to pay another £12 for a sim card. No idea how it performs as I haven't fitted it yet. I also object to the headings required with this review. Its a bloody alarm, so where does 'sheerness' (whatever that might be) come into it? It doesn't have wifi capability, so why does it ask about wifi signal? I'm beginning to wonder what the validity of these reviews might be. You have been warned!

Great item just wish it wouldn’t been when u set the senser off this shows were it his to a potential thief so they could just smash it with anything before it calls you.

Delivery from Royal Mail arrived before estimated date. PIR is very easy to set up with clear supplementary instructions attached by seller. GSM notification works fine with an EE pay as you go sim card. You can hear the device dialing when it is activated but I can live with it. Currently using it as a backup to my landline home alarm system. I have de-activated the siren to make it stealthy but have not been able to de-activate the beep when motion is detected by the armed system. Overall, the product is well built and robust.

great alarm, does exactly what it advertises, Tis so good that it calls your phones (you can select up to 3 numbers) when the alarm is tripped, very happy with this system, no false trips, although this alarm is a little expensive it is worth it. the alarm is loud enough but not as loud as a car alarm, I tend to use it on stealth mode, which means when the alarm is tripped it does not sound an alarm but it does call your phone to let you know the alarm has been tripped without tipping off the robbers that your onto them!

I live in Israel and have just received it - excellent product, it looks of a very good quality, a lot of options to choose from. I wish it had 2100Mhz frequency as well. Operating instructions are very clear. So far, so good - I am so glad I had bought it.

SMS function works but phone doesn’t

Instructions come in a clear format with these detectors that enable a fast & clear setup.The casing is nothing spectacular, & is held together by the smallest of screws?You wouldn't have thought the design could flaw anymore, but it does!The bracket on which this is supposed to be secured with to say a wall etc is pathetic,it doesn't even attach to the detector enough to hold it, let alone attach anywhere else that you had in mind.Throw the bracket out, it's useless. Apart from this the detection unit works really well. I run mine on silent& have covered in black tape. This makes it more stealthy & hides the red light that flashes when it has madeits detection. It will sound a small bleep on detection but thats it.It takes approx 1 minute to ring the no.s you have setup on the device from detection. In silent mode this should be e-nuff timeto respond if something dodgey is taking place.I always keep clothes at the ready for quick exit to check on potential thieves.I run both detection systems that I have on a contract 'EE' full size sim card. Great reception & neither have never let me down.Batteries do run out faster if units are constantly making detections, but can last upto 3 months with min detections.When it rings my mobile, I answer it then I have 2 choices:# will stop the device from ringing you from further detections* will reset the device to detect further intrusionsThere are more options but these are the only 2 I currently use, this works fine for me.These units are expensive, but so is having ur valuables robbed.These will do for now until better technology arrives to fit the same purpose.cheers.

Attention, le message met beaucoup de temps à être envoyé car l'appareil n'est pas connecté en permanence au réseau GSM pour des raisons d'économie des piles. Ça laisse largement le temps de le désactiver..Donc... Un usage limité.. Dommage.

Tres bon rapport qualité prix. J'y ai mis un forfait free à 2€. Fonctionne parfaitement. Le sms arrive assez rapidement. L'appel un peu plus long. La sirène pas assez puissante. Je vais y installer la sirène solaire extérieure.

Je l’utilise pour mon camping car

Sav ultra competant serviable et très connaisseur du matériel enfin in sav qui dépanne ! Bon matériel en plus

fonctionnement impeccable, le plus dur est de trouver un téléphone qui permet de décerouiller la carte sim, sinon, simple, facile à installer et gérer
