How to approach a surveillance system
Start with the location and viewing needs
Define entrances, passageways and details you need to distinguish. Position and framing help determine the lens and camera design.
Compare IP and HD CCTV for the installation
Review the data network or existing coaxial cabling. Technology determines cameras, recorder, connections and expansion options.
Plan recording and everyday use
Decide how to view images and how long to retain them. Check storage, communication and each model's functions.

Questions before buying
Where should I start without an existing system?
Define areas, cabling and recording needs. Then choose a technology and check compatible equipment.
Is a higher-resolution camera always the best choice?
Resolution alone is insufficient. Lens, lighting, position and system capacity also affect the useful image.
