Remote loudspeaker designed for residential, commercial or industrial applications to enable a dial-in to to warn off intruders over a weatherproof loudspeaker. A normal phone call into the unit projects very loud (adjustable) audio directly at the intruders. Watching them scramble, priceless. Add a touch of pure satisfaction to any CCTV system. Now, you can not only see intruders but also tell them, loudly, what you want them to do. As an added benefit the system can be automatically triggered by 3rd party systems such as CCTV, intruder or standalone sensors to initiate an automate 'pre-recorded' message without any user input. Used as a pre-warning, a remotely-located CCTV operator can also dial in to speak 'live' through the loudspeaker.
