                                             TIME LAPSE VIDEO RECORDERS



INTRODUCTION

Time lapse video recorders are designed specifically for the CCTV Security Market, and
are used so that a single VCR tape cassette can be operated for as long a period as possible
without having to change the cassette.

One of the major characteristics which distinguishes VCR for CCTV use from the Domestic
VCR, is the ability to record in the TIME LAPSE MODE.

Instead of recording at 25 frames each second, a time lapse VCR can record fewer frames
per second. Time is allowed to elapse between the recording of each pair of fields, thus
we have the term “time lapse”

The VICON RANGE offers products that meet the requirements of the vast majority of
installations.



We have FOUR MODELS
