Define the required result for each area
Installing four cameras describes equipment, not the task. An entrance may require facial detail, a warehouse may require visibility of stock movement, and a shared room may require the sequence of events. Each goal affects camera position, viewing angle and testing.
Mark monitored areas and areas that do not need recording on the plan. A wide view may show the whole room without preserving useful detail. More megapixels do not compensate for unsuitable height, backlighting or furniture blocking the view.
Test difficult lighting on site
Daylight footage does not establish evening performance. At an entrance, test a person against bright outdoor light; outside, test movement under normal night lighting. Examine saved recordings as well as the live view.
Use ordinary walking speeds and distances. A stationary person can conceal motion blur. Keep an agreed sample for comparison with final installation settings, and do not change acceptance criteria without agreement.
Calculate storage and test exports
Retention depends on camera quantity, bitrate, recording mode and usable capacity. Estimate continuous recording as bitrate multiplied by time, converting bits to bytes. A 4 Mbps stream produces about 43.2 GB per day before overhead. This is a calculation example, not a guaranteed camera storage rate.
Variable bitrate and event recording change actual usage. After installation, inspect storage growth and what happens when the archive is full. Test locating a time, exporting a clip and playing it on another computer.
Assign access responsibilities
Decide who can watch, export and change settings. Use individual accounts and restrict remote access. Do not expose the recorder interface to the internet without a considered protection and updating scheme.
Agree camera locations, purposes, notices and retention with the organisation's responsible staff under applicable requirements. A technical design does not replace that assessment. Obtain camera diagrams, time settings, export instructions and an access-recovery procedure.
What to check
- Each camera has a verifiable purpose
- Day and night recordings are reviewed
- Storage and export are tested
- Access permissions and responsibilities are defined
