What Is a Security Camera?

A security camera captures video for deterrence, awareness, and evidence. While older systems relied on analog CCTV, modern IP security cameras deliver higher resolution, advanced analytics, and long-term reliability.

This guide focuses on professional IP camera systems like SureVision IP cameras paired with SureVision NVRs.

Professional vs Consumer Security Cameras

Not all cameras are created equal. Consumer Wi-Fi cameras prioritize convenience, while professional security camera systems prioritize reliability, ownership, and evidence-grade recording.

Core Components of a Security Camera System

  • Cameras: Bullet, dome, varifocal, PTZ, and LPR options
  • NVR: Records, manages users, enables remote access
  • PoE Cabling: One Cat5e cable per camera
  • Storage: Surveillance-grade hard drives sized to retention goals

Camera Types & Use Cases

  • Bullet: Perimeters, driveways, gates
  • Dome/Turret: Entrances, vandal-resistant areas
  • Varifocal: Optical zoom for distance detail
  • PTZ: Large areas and active monitoring
  • LPR: License plate capture at entrances

Resolution & Night Performance

4K (8MP) cameras provide superior identification detail. Proper IR design, bitrate tuning, and camera placement are critical for night clarity.

PoE & Network Cabling

Professional systems use PoE (Power over Ethernet), sending power and video over a single Cat5e cable. For 16+ cameras, PoE switches simplify installs.

Installation & Placement

  • Cover entrances and high-value areas first
  • Mount outdoor cameras 9–12 ft high
  • Avoid aiming directly into lights
  • Overlap fields of view

Storage & Retention

Storage depends on camera count, resolution, and recording mode. Multi-TB drives are common for 8–16+ camera systems.
