Time Server Settings
Note - If you use a time server, the ComCam will run its system clock in GMT time and keep it accurate
by updating it from a time server every day. Your TIMEZONE_TZ value will tell the ComCam how
many hours your timezone is from GMT, and when your Daylight Savings Time starts and ends. See
“Appendix I - The TIMEZONE_TZ Setting” at the end of this document for information on creating a
TIMEZONE_TZ value, or consult a Unix system administrator who may be able to provide you with the
correct value for your country.
TIMEZONE_TZ A standard C-language TZ environment setting such as EST5EDT
TIMESERVER_IP IP number or name for a Port 37 time server located on
LAN or internet. The ComCam will contact the time server
to keep its own clock accurate.
(Note - DNS_SERVER setting is required to use TIMESERVER)
TIME_SYNCS_PER_DAY 0=disable n=number of times per day to sync ComCam time
(recommend 1)
Video Settings
DEFAULT_VIDEO_MODE Video mode of your external video 1=NTSC 2=PAL (for BNC models)
DEFAULT_QUALITY Value from 1(lowest) to 5(highest), 3 is recommended, 2 for slow
connections
QUALITY_GROUP Adjusts the built-in values for the video qualities 1 through 5.
0 or 1 is default (recommended), 2 and 3 contain higher quality values

Default 0x0F (BNC) or 0x01 (Lens)
To eliminate cycling through unused inputs on a BNC model ComCam,
change to 0x01 (input 1 only), 0x03 (1+2), 0x07 (1+2+3),
0x0F (1+2+3+4)
PRECYCLE For BNC models with multiple video inputs.
0=normal cycling behavior (switch as inputs are requested)
(good for multiframe-per-input cycle, good for composite output)
1=pre-grab all recently requested inputs in order.
(good for soft-quad display or recording, bad for composite out or cycle)
INPUT_IS_SVIDEO 0=no 1=yes with inputs 1+3 and 2+4 are luchroma pairs
VIDEO_SPEED Specifies the highest quality which will attempt to retrieve every frame
from the compression chip. Higher qualities will attempt to get every
