Introduction
This section describes all types of input and output signals available with Corsight cameras, including their characteristics and when necessary including connection examples. Location and pinouts of the connectors carrying the signals are documented in Mechanic and Connector and cable description.
Power supply
DC power input
CORSIGHT cameras are designed for a power supply input range of 24 V ±10%. The power consumption strongly depends on the connected peripherals — devices being powered by CORSIGHT through the USB or other interfaces. The power consumption of the CORSIGHT itself is typically 15 W, while the total power consumption, including the connected peripherals, should not exceed 25 W. A suitable power supply for CORSIGHT is available from NET.
The customers designing an own power supply will find the information about the power input connector in Section “I/O connector”.
Power over Ethernet (PoE+)
The CORSIGHT cameras can be also powered using the Power over Ethernet option. The cameras are compatible with the Power over Ethernet standard, versions IEEE 802.3af and 802.3at. They should be used with PoE switches (“endspans”) or power injectors (“midspans”) complying with the IEEE 802.3af/IEEE 802.3at specifications.
Both PoE modes (A and B) are supported by the camera. Beware of using the PoE cameras with 100Mbit Ethernet only cables, where the “spare” wire pairs might be omitted. With such cable, the power wouldn't be delivered when using Mode B compatible power sourcing equipment.
The CORSIGHT camera models are classified in the power level class 4. The power consumption with PoE is slightly higher than consumption with a “regular” power supply. When connecting multiple CORSIGHT cameras to a single PoE switch, verify how much total power the switch can provide and how it handles cases when the limit is exceeded.
Both PoE modes (A and B) are supported by the camera.
Beware of using PoE cameras with 100Mbit Ethernet cables, where the “spare” wire pairs might be omitted. With such cable, the power wouldn't be delivered when using Mode B compatible power sourcing equipment.
Connector and cable description
| All the grounds from individual connectors are connected inside the camera. |
I/O Connector and Pinout
