How is the image stream affected by delay and how can I check the delay?
How is the stream affected by delay?
If there is a steady delay that may not have impact on an existing stream. There could be problems in reestablishing a lost connection if the delay is above 30 ms.
How can I check the delay?
You can ping the camera from the client and verify the RTT Round trip time. The RTT should be less than 20 ms. Variations in the RTT will cause jitter which affects the image codec.
By using the ”ping –t” command you can send hundreds of packets and check for lost packets (PER) and jitter (variations in the delay). We recommend that you verify the connection with more than 300 packets. No packets should be lost and the delay should be steady and below 20 ms.
