Connection of DVD Recorder to Security Device

RE: Connection of standard DVD Recorder to Security Camera Processor


On the advice of Radio Shack Tech Support I purchased a "Security Labs Real Time Color Quad Processor Model SLX912" to use in conjunction with 4 external wired security camers AND my LITEON DVD RECORDER.


The Processor uses a "Relay Output" to trigger the security video recorder, herein is my problem. My Liteon DVR has no special "Relay Out" terminal connections so how can I connect it to the processor so that the record function will be triggered?


Thanks,
