Are security cameras enough for a business?

Security cameras are important, but they are usually not enough by themselves. Cameras help record and verify what happened, but they do not replace intrusion detection, access control, alarm monitoring, backup communication, or a professionally configured alarm system. A camera may show someone entering a restricted area, while access control can help manage who is allowed to enter, and intrusion sensors can trigger alerts when activity is detected. For most businesses, cameras work best as part of a complete commercial security system.
