Default VCR help


I have a time lapse video used at my house for domestic purpose. It is
about 18 months old, and now records very poor in the daytime but ok at
night. Is this something to do with the higher peak to peak voltages in
brighter light. If I play an old tape that it recorded all is ok. That
also seems strange as I thought the recording and play head was the same
thing. It is not a camera problem as the picture is perfect on a tv. Anyone
got any ideas. I have tried a head cleaner, but it did not make any
difference.

The BNC from the camera goes directly into the VCR. The VCR output then
goes to a Quad and RF modulator, so picture can be distributed to all TV in
the house.

I can see no way that it could make any difference to the VCR itself

whether it's day or night. Has to be something about the signal coming into
the VCR.

If it were the input to the VCR, surley the output from the VCR wouuld show
the same poor picture ? The monitor actually shows a perfect picture day or
night, it is only the VCR that records a poor picture in the daylight.

All I can say, is try it on another VCR to see if you get the same results
or not.
