The DC-Iris Connector
The AXIS 2420 can be used with any standard C/CS lens. With full support for standard
DC-Iris lenses, the camera will automatically regulate the amount of light entering the
camera.
The DC-Iris Connector provides the power and control signalling required for a DC-Iris
lens. The connector is located on the rear panel and the pinout for the connector is shown
below.
The BNC Video Output
The BNC Video Output can be used for connecting the AXIS 2420 to a traditional analog
CCTV system or to a VCR. This output can be used independently of the Ethernet network
connector and both can be used at the same time. The output conforms to 1.0V (p-p) 75
Ohms, sync negative.
The Ethernet Network Connector
The RJ-45 network connector is used to connect the AXIS 2420 to a 10/100Mbit Ethernet
network running TCP/IP.
