Frequently Asked Questions

How much estimated network traffic should I expect while using an e-Watch® camera?
The answer depends on a number of factors, including the type and quality of the MPEG stream, the refresh rate of the JPEG image, and the purported amount of activity for the viewing area. The e-Watch® camera has the ability to compress and transmit up to 3 simultaneous streams. The typical configuration is as follows:
  1. 30fps MPEG1 Multicast at 800kbps bandwidth, 352 x 240 resolution sent from the camera to the multicast switch or router, NOT to the server and NOT broadcast over the network.
  2. 30fps MPEG1 Multicast at 128kbps bandwidth, 176 x 112 resolution sent from the camera to the multicast switch or router, NOT to the server and NOT broadcast over the network.
  3. TCP socket connection transmits JPEG images, 704 x 480 resolution, variable frame rate, to the archive server for later review.
