GENERAL OPERATION REQUIREMENTS
A minimum of one control device is required for operation, such as a control
keyboard, or a recorder. The CM-512 includes a built-in receiver that decodes
commands from a control device.
Connect dome cameras to other devices, as shown in the diagram below, to complete
a video surveillance system.
System Configuration
Note
To extend the network distance up to 1.2 km (4000 feet) and to protect the connected
devices, OpenEye recommends placing a repeater at the mid-point. However, a repeater
may be needed with network distances less than 1.2 km if the cables used are not CAT 5,
24-gauge cables. Refer to the repeater’s manual for detailed information.
