Connectors and Buttons
For specifications and operating conditions, see page 10.
BNC Connector
Each video input is terminated using a coax/BNC connector. Connect a 75 Ohm coaxial video cable;
the recommended maximum length is 250 m (800 ft).
Note
75 Ohm video termination can be enabled/disabled for the video input through the
product's web page at Video & Audio > Camera Settings > Video termination. This
termination is enabled on factory default. In cases where the product is to be connected
in parallel with other equipment, for optimum video quality, it is recommended that
termination be enabled for only the last device in the video signal chain.
Network Connector
RJ45 Ethernet connector.
The unit can only use one Network interface, either an SFP module or RJ45 connector. SFP module
has higher priority than the RJ45 connector.
NO NO TICE NO TICE TICE
The product shall be connected using a shielded network cable (STP). All cables connecting
the product to the network shall be intended for their specific use. Make sure that the
network devices are installed in accordance with the manufacturer's instructions. For
information about regulatory requirements, see Electromagnetic Compatibility (EMC) on
page 2 .
I/O Connector
Use with external devices in combination with, for example, tampering alarms, motion detection,
event triggering, time lapse recording and alarm notifications. In addition to the 0 V DC reference
point and power (DC output), the I/O connector provides the interface to:
• Digital output – For connecting external devices such as relays and LEDs. Connected
devices can be activated by the VAPIX® Application Programming Interface, output
buttons on the Live View page or by an Action Rule. The output will show as active
(shown under System Options > Ports & Devices) if the alarm device is activated.
• Digital input – An alarm input for connecting devices that can toggle between an open
and closed circuit, for example: PIRs, door/window contacts, glass break detectors,
etc. When a signal is received the state changes and the input becomes active (shown
under System Options > Ports & Devices).
