Description of Performance
1.Brief introduction
The keyboard controller is a unit used to directly control terminal matching devices such as high/constant- speed dome cameras, decoders, etc. The electric port between the keyboard controller and the receiving terminal is EIA/RS – 485, which enables the keyboard to control as many as 128 speed dome cameras or other terminals within a maximum communication range of 1.5 Km.

Description of Main Functions and Features
1. Photoelectric insulated RS485 controlling mode is adopted for the output of the keyboard, which provides strong anti-jamming and long-distance transmission.
2. The keyboard can control up to 128 Speed Domes or Decoders etc terminal devices. The address of the Speed Domes or Decoders can be set within the range of: 1~255.
3. Variable-speed operation can be applied to the built-in Pan/tilt of the Speed Dome through the keyboard.
4. Lens zooming, focus and iris can be manually controlled through the keyboard.
5. Manually or automatically control can be applied to Speed Dome through the keyboard.
6. Joint-control can be realized by using the Keyboard controller together with one DVR mainframe or embedded hard disk VCR.
7. Preset positions can be configured and invoked in Speed Dome through the keyboard.
8. Tour groups can be configured and run through the keyboard.
9. Left and right limiting positions can be configured and Left&right scan can be run through the keyboard.
10. Home position can be configured, activated and idled through the keyboard.
11. Light and rain-wiper etc ancillary devices can be turned on or off through the keyboard.
