If this device is too expensive for you, you may want to consider signing up for an account at Trapster, a mobile application that can alert you about nearby radars!
How Does It Work?
Users submit speed traps, enforcement cameras, and road hazards, that then alert all Trapster users in the area. A high-tech version of flashing your headlights to alert drivers of potential road hazards.
I think it’ll be helpful if enough Lebanese users registered, don’t you think?
Thanks to @jadhamdan for pointing me to the application via twitter.
