Comprehensive Guide to CCTV Cameras for Businesses

Introduction: Managed Video Surveillance

In the modern professional environment (hospitality, offices, retail), IP video surveillance is no longer just a passive security measure, but an essential extension of the IT network. Deploying these systems requires network expertise (PoE, VLANs, bandwidth) and centralized management. At Wifirst, we help our clients integrate managed video surveillance solutions, ensuring optimal operation on the IP infrastructure.

However, the effectiveness of a surveillance system starts with choosing the right equipment. Given the diversity of models, it is essential to understand the specific characteristics of each camera type and the scenarios for which they are designed. Let's explore the five main categories of professional cameras.

Why the Camera Type is Crucial

The form factor (the physical silhouette of the camera) determines not only its appearance (discretion or deterrent effect), but also its optical capabilities, resistance to vandalism (IK rating), resistance to the elements (IP rating), and, most importantly, its field of view and installation flexibility.

1. Dome Camera

Easily recognizable by its semi-sphere or "dome" shape, this type of camera is extremely popular in indoor and outdoor environments that require both discretion and versatility.

• Features: Vandal-resistant casing (often IK10), mounted directly on the ceiling or a wall. The lens is protected and often adjustable during installation.
• Advantages:
  • Discretion: Less intrusive than the Bullet camera.
  • Ambiguous Deterrence: The exact orientation of the lens is difficult for the observer to determine.
  • Resistance: Ideal for public places or corridors subject to vandalism.
• Typical Uses: Hotel corridors, lobbies, station halls, covered car parks, retail stores.
• Example Model: HIKVISION DS-2CD2743G2-IZS

2. Turret Camera (or Eyeball)

The turret camera is often an alternative to the dome. It consists of a fixed base and a movable casing, resembling an "eyeball" (hence its nickname Eyeball), without the plastic shell that protects the dome's lens.

• Features: Absence of an outer dome, which eliminates problems with infrared (IR) reflection and reverberation. Easy to orient.
• Advantages:
  • Night Image Quality: Better IR performance because there is no glass cover (reflection).
  • Simplified Installation: Very simple mounting and adjustment.
• Disadvantage: Less resistant to vandalism than a true IK10 dome.
• Typical Uses: Office interiors, reception areas, entrances and exits (where IR is critical).
• Example Model: HIKVISION DS-2CD2H46G2-IZS

3. Bullet Camera

Recognizable by its cylindrical, elongated shape (like a "bullet"), the Bullet camera is most often associated with outdoor surveillance or a strong deterrent role.

• Features: Prominent and visible shape, robust casing, and often equipped with a visor for sun and rain protection. Integrates powerful IR illuminators.
• Advantages:
  • Maximum Deterrence: Its presence is immediately noticed.
  • Long IR Range: Ideal for monitoring long distances (perimeter, outdoor car parks).
  • Simple Installation: The articulated bracket facilitates field of view adjustment.
• Typical Uses: Outdoor perimeter surveillance, loading docks, building facades.
• Example Model: HIKVISION DS-2CD1643G2-LIZSU

4. Fisheye Camera (360°)

The Fisheye camera uses an ultra-wide-angle hemispherical lens to capture a complete 360° panoramic view (ceiling mount) or 180° (wall mount) from a single point.

• Features: A single camera covers the same area as 3 or 4 traditional cameras. Distortion is digitally corrected (de-warping) via the video management software.
• Advantages:
  • Total Coverage: Eliminates blind spots in a given space.
  • Cost Reduction: Fewer cameras, cabling, and required PoE network ports.
  • Post-Event Analysis: Allows viewing the entirety of the scene after an event.
• Typical Uses: Large open rooms, conference rooms, elevators, cash register areas, circular lobbies.
• Example Model: HIKVISION DS-2CD6365G1-IVS

5. PTZ Camera (Pan-Tilt-Zoom)

The acronym PTZ stands for Pan-Tilt-Zoom. These motorized cameras allow complete remote control of the lens.

• Features: Powerful optical zoom capability (up to 40x), continuous 360° rotation, and vertical tilt. Often used for automatic tracking (auto-tracking).
• Advantages:
  • Active Surveillance: Can patrol extended areas or zoom in on specific details in real time.
  • Flexibility: Replaces the human operator in monitoring vast areas.
• Disadvantage: Only monitors one direction at a time. Requires programming or human intervention for operation.
• Typical Uses: Monitoring large car parks, warehouses, sports fields, or live monitoring by a security center.
• Example Model: HIKVISION PTZ serie 7 iDS-2CD7146G0-IZ(H)S(Y)
