Planning a CCTV system: questions to answer first
Coverage, image quality, storage and remote viewing — what to decide before choosing cameras.
A good surveillance system starts with clear goals.
What must each camera see?
Decide whether you need to detect movement, recognise a person or read a number plate. This determines resolution and lens.
Indoor or outdoor?
Outdoor cameras need weather protection and good night performance.
How long must footage be kept?
Retention period, number of cameras and resolution decide recorder size and storage.
How will you view it?
Plan the network and user access for remote viewing from authorised devices.
Privacy
Respect privacy rules, avoid filming private areas and display signage where required.
