Overview
This CCTV System Control Keyboard can be integrated with a full range of
CCTV products easily, such as Digital Video Recorders (DVR), cameras and
other CCTV devices with RS-485 interface for remote control and system
configuration. Back lit LCD display and 3-axis joystick control provide userfriendly operations. Built-in firmware upgrade circuits allow users to upgrade
firmware through the RS-232 port.
The system configuration diagram below shows the application of the control
keyboard in a comprehensive surveillance system.
NOTE: To extend the network distance up to 1.2 km (4000 feet) and to
protect the connected devices, it is highly recommended to place a
repeater in the mid-point. However, a repeater may be needed in the network
distance less than 1.2 km if the used cables are not the CAT 5, 24-gauge
cables.
