The 3D Controlling Keyboard can be used alone or together with DVR mainframe and built-in hard disk VCR to control matching terminal products, such as high/constant- speed dome cameras, decoders, etc. The electric outlet between the controlling keyboard and the receiving terminal is EIA/RS - 485, which enables the keyboard to control as many as 127 dome cameras or decoders within a maximal communication range of 1.2 Km. Using the controlling keyboard, you can easily control and set up for variable-speed dome cameras. The controlling keyboard can also directly control terminal decoders so that the control of the front devices such as the constant-speed pan/tilt, the lens, the light, the rain brush etc can be realized. It can connect single or multi DVR mainframes or mainstream stand-alone DVRs, and it can also control all the panel-controlling function.
Characteristics 1. The keyboard output adopts photoelectric insulated 485 control so that it can provides strong anti-jamming and long-distance transmission. 2. Using the keyboard, you can set up dome camera or decoder address at the range of: 1~255. 3. Through the keyboard, variable-speed operation can be applied to the high speed dome camera. 4. Via the keyboard, pre-set positions and tour group can be setup and previewed in the high speed dome camera. 5. Lens zoom ratio, focus and iris can be manually controlled via the keyboard. 6. Joint-control can be realized by simultaneously using the keyboard with one or more DVR mainframes or built-in hard disk VCRs. 7. The keyboard has menu displaying LCD, 3D controlling joystick, as well as DVR or built-in hard disk VCR panel controlling functions.
