video cameras are displayed with an appropriate text message in
single-display viewing areas; that is, when a source other than
VIDEO ALL
is specifically selected.
A blank display - without text, may indicate a break in the signal transmission; such incidents
should be escalated to your system administrator immediately.
Positional Control of the Video Sources
Video cameras supporting Pan Tilt and Zoom (PTZ) control can be attached and positioned
directly from the supported serial ports (
COM 1
and
COM 2
).
Furthermore, the AXIS 2400/2401 can control up to two external (standalone) PTZ devices for
positioning fixed cameras on your system.
All PTZ devices can be steered via the AXIS 2400/2401 Web interface, or TCP application if your
Administrator chooses.
