Gen lock with time and date stamp
The GL-250 synchronization signal generator and time/date text inserter
from JC Labs is designed to synchronize up to six video cameras and
recorders and record the time of day with millisecond resolution on each
Housed in a rugged, aluminum chassis, the GL-250 requires a 12 Volt, DC supply of
approximately 500 milliAmps. The six video channels are individually buffered, and the sync
output signals are AC coupled and capable of driving a 75 Ohm impedance. Each video channel
will also accept a video signal from a camera which can have the time of day superimposed onto
the video output signal. In addition, an audio tone is generated at the press of a front panel
button which may be used as an event tone to mark a recording. The event tone will play back as
a 1kHz tone at standard playback speed, regardless of record speed. The vertical reset is set at the
factory to provide a 262 1/2 lines per field. This default may be changed to 262 or 263 lines per
field by setting a switch inside.
A built in real time clock provides date and time stamp for each recorded image with a one
millisecond resolution. The clock is powered by an internal lithium battery for eight years and
provides an accuracy of one minute each year.
- Generates horizontal drive and vertical reset signals for up to 6 cameras.
- Generates event tone which plays back as 1 kHz at 60 fps.
- Time of year to millisecond precision can be recorded on each video image.
- Lithium battery backup keeps clock running 8 years without power.
