Gestton has launched the wireless EG-570 camera-tracking conference system which uses IR to transmit and control.
The main controller can manage up to 128 units, with a maximum of three delegates and one chairman working at the same time.
The main controller and speaking unit both have an LCD display, and a built-in Li battery supports 8 hours of continuous speech or 25 hours in standby.
The microphone unit is a hyper-cardioid directional gooseneck mic, with an LCD display to show signal status, battery capacity and microphone ID.
The IR signal receiver can be wall- or ceiling-mounted, and has a vertical lens shift of 75deg and horizontal lens shift of 360deg.
