state of the art unit can, when triggered, activate a standard
domestic video recorder to record, then switch it off after an
adjustable delay The record time is adjustable ( 30 secs - 5 mins
) because different applications require need different approaches.
An area where there is a regular traffic flow at certain periods
( e.g. rush hour , school leaving etc ) will need a shorter record
period, to allow for the frequent activation's at these times than
a more remote area, with little traffic.
in a domestic situation, when the occupiers are on holiday, a Video
Controller has been set for 2 mins each activation, then a normal
LP video recorder with a 240 tape will last 8 hours, so giving
240 activation's. If the property is visited, and detectors activated
on an average of 10 times a day ( quite a high rate ) then the
property will be protected for 24 days.
the Video Controller is used in conjunction with the Advanced Vision
4 camera switcher, then when an alarm activation occurs, then the
switcher sends an audio tone down the coaxial cable to the video
recorder. This audio tone can be used to activate the Video Controller,
so allowing a totally wire free installation, resulting in no damage
to decor. It will only activate the video when it is on the CCTV
camera channel, so it will not record over your favorite tape.
Video Controller can also be activated by any DC input from 4 -
24 volts, which allows it to be controlled by any alarm panel,
P.I.R. detector, Motion Detector even by the doorbell. By utilising
almost any domestic video recorder, the Automatic Video Controller
can allow you to have a sophisticated CCTV security system, while
using your existing video recorder and TV.
