If you are getting interference from these devices, the only action you can take is to move to a different location, or to change to a different transmitter on a different frequency. The width of the tape in a VHS recorder is 12mm. An 8mm tape has a width of 8mm. There is no way to get the heads in a VHS VCR to read the tape correctly. Real time recording uses a full 30 frames per second recording.
Time lapse is anywhere below that.
The advantage of using time lapse over real time is longer recording times. The main disadvantage is the longer the record time, the more information is missing. You can use any standard VHS tape for recording in time lapse. Just remember to replace your tapes often. The most popular configuration is with a PIR motion detector wired to trigger the VCR to begin recording any time there is movement in the area.
