Outdoor security beams needed for a window

[Mimen]

The previous guy that put in my alarm put gate sensors in front of my windows. They don't have a dual beam and even insects sets it off.

I'm looking a security device that will have a beam in from of the windows, about 4 meters long. Any ideas on what brand and model to look at?
I can find beams for 2 grand or more, seems excessive for a window only.

Thanks!

Try Regal security, probably other companies out there, this the first one that popped into my head.

Hi, I have a Selco strip barrier beam in front of my house, it covers 4 windows and my front door.

It has 6 beams and 2 or more must be broken before the alarm sounds. I have very few false alarms with it, mostly because of a damn cat that sits on my window still
