This device may be used with most Remote Control VCRs to automatically Record 'Events', the VCR-CONT will automatically and wirelessly transmit the VCR Power-On, Record, Stop and Power-Off commands.
VCR-CONT is triggered by a 'normally closed' set of Alarm Contacts, when the contacts open the Power-On & Record commands are transmitted, when the Alarm Contacts close the Stop & Power-Off commands are transmitted either immediately or after a 5 minute delay period.
Most PIR / Microwave / Ultrasonic and other Movement Detection sensors are suitable, Light Beam Sensors and Mat switches may be used across entrances and doorways, a simple magnetic 'Reed' or 'Micro' switch is all that is required to detect opening of doors, etc.
Installation is simple, only two wires are needed from the contacts to VCR-CONT, if VCR-CONT and Sensor are powered from the same power supply only one wire is required.
Multiple alarm and camera inputs can be managed by using a Quad or Multiplexer with Alarm I/O, the programmable Alarm Output Period may be used to control recording, a Quad with Full-Screen-Call On-Alarm function could be utilised to quadruple recorded data compared to an ordinary Quad Screen recording.
This device may also be used with our Remote Control VIDEO-VGA (click here for info) to automatically display images from a Surveillance Video Camera on a Computer Monitor that is being used for normal computing purposes.
Any of the methods above could be used to trigger VCR-CONT which is programmed with the VIDEO-VGA VIDEO and PC SELECT Commands. When triggered the VIDEO SELECT command is transmitted and images from the Video Camera are instantly displayed on the PC Monitor, when the Alarm Contacts close the PC SELECT command is transmitted and the PC Monitor switches back to the Computer.
A single VCR-CONT could be used with multiple PCs and VIDEO-VGA units to increase the number of observers.
This arrangement would provide highly reliable monitoring in situations where people are using computers continuously and important areas need to be kept under surveillance. The possibilities are numerous and include monitoring of rooms containing money, valuables, drugs, etc,. persons entering / leaving a building or sensitive areas, removal of a valuable item on display, arrival / departure of vehicles, etc, etc,. Cash Registers could be more efficiently monitored (with less boredom) by using alarm contacts on the drawer.
At home, a similar
arrangement could provide automatic Display on TV of images from a Surveillance
Camera while viewing TV programs, Tapes, CDs, etc. VCR-CONT could be programmed
with the Television AV Video or Camera Channel (when using
UHF-MOD RF Modulator) Select Command, images
from the Camera would be instantly displayed in response to an Alarm Signal from
a common PIR Motion Detection Lighting System, Light Beam Sensor, Mat Switch,
Pool Gate Switch, etc etc. Multiple Cameras could be managed with a
Quad with Alarm I/O and
Full-Screen-Call On-Alarm facility.
Alternatively multiple Cameras could be managed by using VCR-CONT with each
Camera, each VCR-CONT could be programmed with a different AV Video or Camera
Channel Select Command. Compatible with most
common domestic VCRs, the original VCR Remote Control is used to 'Teach'
VCR-CONT the VCR Remote command codes. VCR-CONT transmits
Power-On & Record commands when the normally-closed Trigger Input contacts are
opened, depending on the 'User selectable Mode' the Controller will transmit VCR
Stop & Power-Off commands when the Trigger Input contacts close again or after a
5 minute delay. Indicators:
Red LED = Power On.
Orange LED = Learn / Transmit.
Two pushbuttons: to learn 2 x 2 commands.
Switch: instant or delayed transmission of commands on contact closure.
Power Supply: 9 ~ 12 Volts DC ~ 8 milliamps.
closed (trigger to negative), open to initiate transmission of Power-On & Record
commands. Power & Trigger
connections via 3.5 mm Stereo Phono socket. Output:
For an external Infrared LED (not supplied), via 3.5 mm Stereo Phono socket, internal LED disconnects when Plug is inserted.
~ 85 mm Wide, ~ 67 mm Deep, ~ 38 mm High, ~ 65 grams, excluding mounting bracket. Supplied with ~ 600 mm Cable with 3.5 mm Stereo Phono plug, 2.1 x 5.5 mm Power Supply input socket and stripped and tinned Trigger input wires, Mounting Bracket, Screws & Wall Plugs.
Use this Controller
with a low-cost domestic Extended Play VCR for 12 / 15 hour Real-Time (25
Frames-per-Second) recording with a 4 / 5 hour cassette.
