Network (and PoE) connection
1. Use a shielded twisted pair (STP) Category 5e cable,
maximum length 100 meters.
2. Use the RJ45 female-to-female network cable connector to
connect the network cable of the system to the RJ45
connector of the camera (Auto MDIX compliant).
Power is supplied to the camera via the Ethernet cable,
compliant with the Power-over-Ethernet standard.
Note:
The RJ45 female-to-female network cable connector supplied
with the camera is unshielded and is appropriate for all
applications that use unshielded twisted pair (UTP) network
cable (most types). For applications that use shielded twisted
pair (STP) connection cable and need to meet the EMC Alarm
immunity standard (EN50130-4) or the EMC Railway imunity
standard (EN50121-4), a shielded RJ45 female-to-female
network cable connector (not supplied) shall be used.
Alarm Input
Use the alarm input to connect external alarm devices such as
door contacts or sensors. A zero potential make or break
contact can be used as the actuator (use a bounce-free contact
system).
