Eight channels
An eight-channel recorder fits focused home and small-business systems when the final camera count is comfortably below eight.
Sixteen and thirty-two channels
Sixteen channels provides room for many small commercial sites. Thirty-two channels becomes practical for larger buildings, parking areas, multiple entrances, and phased projects.
Avoid a zero-growth design
- Reserve channels for future blind spots.
- Plan storage for the cameras you expect to add.
- Document cable paths during the first installation.
