Writing novel, questions about early 1990s CCTV
Hopefully someone here has the expertise to help me with these questions. I know CCTV was around in the early 90s, but I don't know the technical details.
- Recording: did the CCTV footage record onto film, video tape, cassette tape, DVD, or something else?
- Did the cameras run on batteries, or would they stop working in a power cut?
3.If a time-lapse CCTV was being used, would that be more expensive, or the cheaper option?
Thank you!
Edited to add - thank you everyone for this information - it's exactly what I needed and very useful.
