Auto Switch Combined with Video Relay
By Operating Auto Switch in combination with Video Relay, you can effectively switch cameras
assigned to viewers that are set on several camera servers and display video.
Let us look at an example of two camera servers, each of which has four cameras connected for
monitoring by Video Relay while cameras assigned to viewers are being switched. Camera Server
1 has Cameras A, B, C and D, while Camera Server 2 has Cameras E, F, G and H, each
assigned to four viewers switched by Auto Switch.
Video Relay is set up for A to F to sequentially display video but G and H may monitor with still
pictures.
The Video Relay interval for Camera Server 1 is set to five seconds and the sequence is A, B,
C, D.
The Video Relay interval for Camera Server 2 is set to ten seconds and the sequence is E, F,
G, H.
The Auto Switch intervals are set to 30 seconds for A to D and to 20 seconds for E to H.

First, Video Relay is
r e p e a t e d
sequence A to D during
the 30-second interval.
After 30 seconds, it
switches to the E to H
video pattern but since

However, G and H are
updated to the latest

pattern is switched.
The still pictures of
