Alarm. Too good to be true?

Home security alarms| low-cost portable wireless burglar alarms | Sonis Europe

I'm not sure how large a property this might work on but certainly souds like an easy soltion for a shed or garage with a power source.
Again my inbuilt cynicism wonders about false alarms with passing traffic, house settlement, rain lashing down etc..
Any experience

Alarm. Too good to be true?

Interesting but I wouldn't trust it for my house.

You could become very unpopular with the neighbours! Having said that burglar alarms generally only make you unpopular with the neighbours as they usually only go off when you are out and the cat is shut in the sitting room!

Any alarm system has the potential for false triggering. I fitted an extremely sophisticated system into my surgery..door jamb detectors/ pir and microwave sensors and glass break detectors coverign every external and internal door, window and room so even if clever burglar got past the first tranch they would't be able to relax plus dual sirens you'ld have to disable simultaneously and several internal howlers. Yes they did gve a rare false alarm.. but have to switch off after 20 mins anyway.. and of course nothing protects against a noisy ram raid. The whole idea is deterrance and generally a good overt system does just that. All my internal detectors were obvious, many had little flashing leds but again all were protected within the system by another one - as in you'ld never get to one detector without triggerig different one en route. Obviosu to anyone casing the jiont. BUT it wasn't cheap.
The diea of a system that perhaps emits regular hypersonic tones and recognises their normal echoes (if that's how this one works) and alarms if there is a discrepancy could well work and makes installation and maintenance a breeze.

For a business premises you should consider a smoke cloak system. After we got raided in the last riots we installed one. Diy it cost us less than £500

interesting device, however majority of "real" attempts lately try to short circuit your power by any externally accessible socket which usually runs on the same circuit as the main/bottom floor ... such a device costs less than 50p to produce and will prevent majority of the affordable solutions to fire, so I am not really convinced. No failsafe/backup power, no SIM card module and how does it trigger if your internet provider has downtime or when there is a general power outage in the area?!

I dare say that nothing cheap is going to be perfect

In this case it also alarms to your phone if the central site loses connection to the device, so you would get an alert in the case of power/internet lose.

The main question is what you do as a result of the alert as is always the case with alarms.

I probably wouldn't use a device like this on its own, but as part of a larger system I can see it has uses.

Alo used to eb able to get those subsonic systems that make anyone in earshot feel like vomiting and there's one that makes a discrdant sound like nails on a blackboard that people just can't stand - ear plugs?
