  B. Retain camera recordings on local branch servers, and access video from HQ only when needed.
  C. Configure cameras for H.264 encoding and 15 FPS, store video locally on a server, then transcode the same video stream to 5 FPS before sending it to HQ security center.
  D. Configure dual streaming on each camera, one for high-quality local recording and the other for streaming to HQ over WAN.
  E. Enable multicast within the branch network and unicast video streams when traversing the WAN.
  A. Deploy centralized Cisco VSM solution using H.264 instead of MJPEG encoding in branches with limited WAN speed.
