# Connect the GigE camera to the PC

Aim

To make sure that EthoVision XT receives the video signal from the GigE camera.

Prerequisites

▪You have followed the entire procedure in Install an Ethernet board for GigE cameras.

▪No matter how many cameras you use, you need a 1-Gb Ethernet interface board (desktop computers only).

▪When you use a 4-port Ethernet board, you can power the cameras with Power-over-Ethernet (PoE) injectors but you can also choose to connect the board to the power outlet inside the PC. See Power the Ethernet board for the GigE cameras

▪You must use a 1-Gb (1 Gigabit/s) Power-over-Ethernet (PoE) injector:

▪When the Ethernet interface board is not powered. This is usually the case for 1- or 2- port boards. Also 4-port boards may not be powered - See Power the Ethernet board for the GigE cameras

▪When you use a network switch ant this has RJ45 ports that are not powered. In all cases, use one PoE injector per camera.

▪Cables: Use Cat5e or Cat6e crossover cables.

▪Do not use an Ethernet to USB adapter (in the picture below) to connect the camera to the PC. Always connect the camera and the PC directly using an Ethernet crossover cable.

Procedure

If you have a single or dual port Ethernet board

To connect one camera, you need a single or dual port Ethernet interface board. To connect two cameras, you need a dual port Ethernet interface board. If the board is not powered, you need as many PoE injectors as cameras. Only use 1Gbit/s PoE injectors.

1.Using cross-network cables (cat-5e or newer), connect the Ethernet port/board on the PC to the IN port of the PoE injector. Connect the camera to the OUT port. Use the short cable between PoE injector and PC. Use the long cable between PoE injector and camera.

2.Power up the PoE injector; make sure that the two CONNECT and ON green LEDs are on.

If the green LEDs keep blinking, wait a few more seconds. If you see no change, disconnect the cables, then re-connect them.

3.Next: Configure the digital camera.

You can also connect two cameras to two single-port Ethernet boards:

If you have a four-port Ethernet board

When you use this board, the PoE injector is not required. However, the Ethernet board must receive power from the PC. See the connection scheme in Power the Ethernet board for the GigE cameras

1.Connect each camera (up to four) to one of the ports on the Ethernet board, as shown in the figure below.

2.Next: Assign IP addresses.

Notes

▪tip Label the cameras and the Ethernet ports (for example Cam 1, Cam 2 etc.). Take note of the camera’s serial numbers; these actions may be useful when you need to know which camera is connected to which port and assign or adjust the IP addresses.

▪The Power over Ethernet (PoE) injector is a device that passes power along with data (in this case, video data from the camera) on twisted-pair Ethernet cabling.

▪If you bought your camera elsewhere, make sure you bought the correct Ethernet cables. Cheap or incorrect cables will affect frame rate and result in missing samples. Always use Cat5e, Cat6 or Cat7.

▪Cat6 and Cat7 cables support higher network speeds (5 Gb/s or higher) than Cat5e (2.5 Gbps), but these are way above the network speeds required for a GigE camera and Ethernet board.

▪Cat5e cables are cheaper, lighter and thinner and may be the preferred choice for some applications due to ease of installation in tight spots. They are typically easier to terminate as well.
