Monitor Text Overlays

The workstation monitors display the video from the cameras installed at your site. Each monitor has an

identification number associated with it based on its physical connection point on the AD168 switching

bay. In addition to the camera video, switching monitors also display a text overlay which provides

information about the camera view being displayed. The illustration below shows the basic format of the

monitor screen text overlay. The standard monitor title and time/date display has a format of two rows

with 24 characters per row. The monitor number/status section consists of 2 rows with a maximum of 7

characters per row. The camera/preset title section consists of 2 rows with a maximum of 8 characters

per row. The date and time section consists of 2 rows with a maximum of 8 characters per row. There is

always 1 blank character on both of the 2 rows inserted between the camera/preset title section and the

time/date section. The alarm title area appears above the standard display, and consists of 2 rows

having 24 characters each. All 48 character positions in the alarm title area can be used if required.

a) Camera Number - this identifies the camera being viewed. The number will either be a real number

corresponding to the camera’s physical connection point on the AD168 switching bay, or a pseudo

number, which is a convenient substitute for the real number that gives a clue as to the camera’s

location or functions.

b) Status Line - this shows the current status of the camera being viewed. Status information includes

camera dwell times, alarm information, tour status, etc. A complete listing of status line displays is

included in Appendix B of this document.
