Camera Data Interfaces

Emergent Vision Technologies cameras have one of the following data interfaces, depending on the model’s camera family:

• 5GigE RJ45
• 10GigE RJ45
• 10GigE SFP+
• 25 GigE SFP28
• 100 GigE QSFP28

Camera data interface ports

This section describes the data interface ports on Emergent cameras.

RJ45 data interfaces

The RJ45 port used in Emergent’s Eros, HT, and Pace LT cameras is a standard port for 5Gb and 10Gb Ethernet applications.

‍Note: Eros cameras, but not HT and Pace LT cameras, support power-over-Ethernet (POE), so you can power Eros cameras through the RJ45 port instead of the GPIO port.

SFP+ data interfaces

The SFP+ port used in Emergent’s HR and Pace LR cameras is a standard port for 10Gb Ethernet applications. SFP+ stands for “enhanced small form-factor pluggable.” SFP+ has significant advantages over other Ethernet cabling options, including a variety of cabling options including Direct Attach, which is a copper-base solution for reliable transmission up to 10m, and Fiber Based Transceiver solutions for significantly longer transmission distances limited only by the available fiber transceiver technologies.

SFP28 data interfaces

The SFP28 port used in Emergent’s Bolt and Accel cameras is a standard port for 25Gb Ethernet applications. SFP28 stands for “small form-factor pluggable 28”, which has a maximum data rate of 28 Gbps. SFP+ has some significant advantages over other Ethernet cabling options including a variety of cabling options including Direct Attach, which is a copper-base solution for reliable transmission up to 10m, and Fiber Based Transceiver solutions for significantly longer transmission distances limited only by the available fiber transceiver technologies.

QSFP28 data interfaces

The QSFP28 port used in Emergent’s Zenith and Pinnacle cameras, is designed for 100 Gigabit Ethernet applications. QSFP28 stands for "quad small form-factor pluggable 28”, which has a maximum data rate of 28 Gbps in each of its four channels. QSFP28 supports high-speed data transmission, making it suitable for demanding applications that require substantial bandwidth.

Connecting camera data interfaces to NICs

The type of cable used to connect an Emergent camera's data interface to a NIC depends largely on the type of data interface.

Installing RJ45 CAT cables

CAT cables and RJ45 connectors are standard for 10GBase-T Ethernet, with keyed connectors to prevent incorrect insertion. Insert one end of the CAT/RJ45 cable into the NIC’s RJ45 port and the other end into the camera’s RJ45 port until you hear a "click," indicating it is latched. To remove the cable, lift the release tab on the underside of the connector, which disengages the latch, allowing you to pull the cable out.

Installing SFP+ direct attach cables

SFP+ is a 10G standard with Direct Attach Cables (DACs) that connect the NIC and camera directly without separate transceivers. Insert the SFP+ cable into the NIC and camera ports until it clicks, signaling a secure connection. To remove, pull the release tab on the connector’s underside to disengage the latch. Note that different vendors may use varying latch mechanisms, so check the instructions for your specific cable.

Installing SFP+, SFP28, and QSFP28 fiber transceivers and cables

SFP+, SFP28, and QSFP28 transceivers are used with fiber optic cables for high-speed connections. First, insert the LC fiber into the optical transceiver, then install the assembly into the NIC and camera. To remove, first disengage the LC-LC fiber by pressing the release latch on top of the fiber connector. Next, pull the latch on the transceiver outward and down to slide it out of the cage.
