Camera Setting Requirements
Network (continued)
Insufficient Network Bandwidth
When there is insufficient bandwidth, the number of JPEG frames (frame rate) that the client can acquire will decrease. Also, the image distribution will delay. In the case of H.264/
Network Delay
When the client acquires JPEG via TCP, camera will send out data while checking the ACK from the client at the same time. For networks with considerably delay, data cannot be sent out until ACK is received, and therefore the frame rate will drop. In the case of
Network Jitter
When there is considerable network jitter, delay time may be prolonged and the image frame rate may drop. In the case of
Packet Loss
When acquiring images from camera via TCP, packet loss may be recovered by TCP transmission. When there is considerable delay in the network, however, data may lost and the image frame rate may drop. In the case of
If a packet is lost during multicast transmission from camera, the image frame rate may drop. In the case of
List of Protocols and Port Numbers used by Camera
The camera uses the following protocols and port numbers. Ensure that these ports are allowed through the firewall when a firewall is to be installed.
