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. 
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: 
The unit does not support alarm or motion recording for IP cameras.
IP cameras only record in the normal recording mode.
The IP camera video stream must be configured as recommended by Pelco (refer to Figure 6).
