Conceived for being used for the video surveillance, the television cameras PTZ (Pan, Tilt, Zoom) are also affirmed in the field of the television shots thanks to a quality that is now equal the classical videocameras (they exist in version with 3 ccds and also for high definition), but above all for the fact that being controllable by remote, they don't have need of a cameraman that manages it, they are very small and little invasive especially when the shots are executed in particular environments: churches, places of cult, surgery rooms, etc...
The Elman has realized to the purpose: RCU-PTZ, a very simple remote control that allows to drive from distance, television cameras type PTZ, with VISCA protocol interface.
L' RCU-PTZ is very intuitive in his operation and it is realized in an elegant aluminum box.
-4 positions joystick for the adjustment of movement in horizontal (Pan) and in vertical (Tilt)
-2 positions joystick for the regulation of the zoom (from tele to wideangle).
-button switch for activation and deactivation of the digital zoom with relative signaling led
-button switch for select manual or automatic focus (2 leds show which of the two functions it is selected)
-knob for regulation of focus in manual mode (Far/Near)
-button switch for the selection of the control of the opening of the iris: automatic or manual (2 leds show which of the two functions it is selected)
-knob Bright/Dark for the regulation of the iris opening (in manual)
-button switch for the activation of exposure control with Backlight, with relative signaling led.
The remote control RCU-PTZ also has an input Tally, for connection to the video mixer of the control room, that allows to turn on the led for signaling "On Air" when the television camera is selected from director.
The cable coming from the television camera PTZ is connected to a connector D female with 9 pins (protocol VISCA - RS422).
Particularly the RCU-PTZ has been tested with success with Sony television cameras model: EVI-D70, EVI-D100 and EVI-D30 but the range of models with which it can be interfaced is very wide.
The remote control is powered with a 8-12 V voltage (150 mA) supplied by a external power supply (given with RCU-PTZ)
