The complete CCTV system consists 5 main components;
- Security Cameras (Analog or Digital Camera)
- Cables (RJ45 or RJ59 Cables)
- Video Recorders (DVR or NVR)
- Storage Units – Typically Hard Disks
- Display Units – Monitors

Operators can carefully watch out for any suspicious activity, capable threat, patient distress, overcrowding, or any kind of malpractice taking place inside the hospital.
4. Market research
Market intelligence garnered from video surveillance of clients is getting used to research the latest trends and permit improved strategies i.e. how people shop, which aisles they navigate the most, and how possibly they reply to calls to action inside different store layouts. Heat maps can display the highs and lows of consumer traffic at unique places in a store, assisting shops to become aware of peak shopping times, desired merchandising types, and staffing necessities for peak buying periods.
