CONNECTING ANALOG CAMERAS

DX4708/DX4808 units support up to eight analog cameras and two IP cameras. DX4716/DX4816 units support up to sixteen analog and two IP cameras. Be sure to disconnect power from each camera before connecting it to the unit. Also, use 75-ohm video coaxial cables with BNC connectors to connect the analog cameras to the unit. Refer to Table A for coaxial cable requirements.

Table A. Video Coaxial Cable Requirements

Cable Type*	Maximum Distance
RG59/U	229 m (750 ft)
RG6/U	305 m (1,000 ft)
RG11/U	457 m (1,500 ft)

*Cable requirements: 75-ohms impedance All-copper center conductor

All-copper braided shield with 95% braid coverage.

NOTE: Operational issues may occur when analog cameras are not correctly terminated. When connecting camera devices, use a normal termination of 75 ohms. When using the video loop-through option, make sure the signal is terminated at the last device. For additional information about terminating a specific device, refer to the device’s installation manual.

CONNECTING IP CAMERAS

The DX4700/DX4800 supports up to two IP cameras. For information about the supported IP camera resolutions, refer to Appendix D: Supported IP Camera Resolutions in the DX4700/DX4800 Series Server Operation/Configuration manual.

NOTES:
