Network Connector

The AXIS 2420 is designed for 10 Mbps Ethernet and 100 Mbps Fast Ethernet networks and connects to the network via a twisted pair category 5 cable (10baseT and 100baseTX), terminated using

astandard RJ-45 connector. Supporting NWAY, the AXIS 2420 detects the speed of the local network segment and varies the speed of data com- munication accordingly (bet- ween 10 Mbps and 100 Mbps).

Video Out Connector Via a standard BNC connec- tor, this output allows the AXIS 2420 to be connected directly to traditional CCTV systems. It can also be used for adjusting the camera focus in locations where you are unable to view images on a computer screen.

I/O-B Connector

Provides the physical interface for:

•1 relay switch output - used for the control of external surveillance devices and ser- vices; e.g. lighting annuncia- tors, audible alarms, etc.

•RS-485/422 port for the con- nection of pan tilt devices, etc.

Note: The power supply for your AXIS 2420 is country-specific. Please refer to the Hardware Inventory on page 11 and check that the type of power supply you are using is correct.
