What type of Omega alarm is this?

Question

I do a paper-round and at one of the houses is some sort of alarm. It isn't a car alarm, it's fixed to the corner of the house. It seems to omit a very high frequency noise whenever I go near it, so it's motion-sensored. It says Omega on it, with the O as the Greek symbol. I can't find it anywhere on the internet, so if anyone could help me out I'd be really grateful.

It's not the usual Omega alarms that you find when you merely type Omega Alarms into Google, so I don't know what it is.

Anybody know what it is?

Answer 1

It could just be Omega security systems
The high freq. noise may be intended for animals (cats and dogs) so they don't mess up the garden or upset the house animals
