Using the VideoEdge IP Encoder with Intellex IP

• Avoid using cameras that get very noisy in the dark in day/night situations.

Select a camera that delivers a usable image under the expected lighting

conditions.

Network Data

The network bandwidth required for each VideoEdge IP Encoder also depends

on the configuration settings of the encoder and the amount of image motion.

Table 1 summarizes the amount of network traffic per camera under motion and

still image conditions. The network traffic is in bits per second per camera at 30

ips.

There is a 29X increase on the network traffic between no motion at 2CIF and

high motion at 4CIF! And the network traffic from 16 cameras could saturate a

100Mbit network! It is important when designing the network transporting the

video data to isolate the encoders with a high quality gigabit switch so that the

traffic on the 100 Mbit segments is minimized.

Recommendations

• Use quality Gigabit switches to isolate the network traffic.

• Use a dedicated network (not the corporate network) for video data.

• Use one of the Intellex IP NICs for the encoders and IP cameras and the

other NIC for Network Client.
