CCTV Cameras: Camera Ecosystem - Physical Formats and Main Applications. Identifying models based on their deterrent capacity, mobility, and viewing range.
CCTV Format Classification. Representation of the main camera shapes according to their environment and function: from the discreetness of the Dome to the 360° coverage of the Fisheye.
Capture Types: Visual guide to physical devices. Each format (Dome, Bullet, Turret, PT, PTZ, and Fisheye) is designed to balance deterrence, durability, and coverage angle.
Dome: Designed for discretion and protection against tampering on interior ceilings.
Bullet: Designed for visual deterrence and perimeter control outdoors.
Turret: The standard for clarity, eliminating infrared reflections in mixed environments.
PT (Pan-Tilt): Versatile horizontal and vertical mobility solutions for residential spaces. PTZ (Pan-Tilt-Zoom): High-performance cameras for active surveillance and large areas with optical zoom.
Fisheye: 360° coverage, ideal for comprehensive room monitoring without blind spots.
The Classic Dome (Fixed Dome)
This camera has a glass or polycarbonate dome covering the entire body.
Design: The lens is protected inside the dome.
Advantage: It is the most difficult to manipulate or move manually without tools.
The Turret Dome (or Flat-Faced Dome)
Although technically a type of dome due to its circular base, it does not have a glass dome.
Design: The lens is exposed on a rotating sphere.
Important fact: It provides the best nighttime images because it prevents infrared light from reflecting off the glass and blurring the image (a common problem with dirty classic domes).
The PTZ Dome
It is the "big brother". It's called a dome camera because it maintains a dome shape, but it's much larger.
Difference: While a standard dome camera is fixed (you orient it during installation and it stays in that position), a PTZ camera moves remotely.
PTZ (Pan-Tilt-Zoom) Camera
These are large cameras that can rotate 360°, tilt, and have powerful optical zoom.
Uses: Active surveillance. They are used in large areas (parking lots, shopping malls, stadiums) where a human operator or automatic tracking software needs to "follow" a target or cover a huge area with a single camera.
Turret Camera
This is a hybrid camera. It looks like a dome camera, but the lens isn't behind a glass dome; instead, it's a sphere that rotates on a base.
Uses: Very popular today because it eliminates the reflections that dome glass sometimes produces with infrared light. They are easy to adjust and offer very clean image quality for residential and commercial outdoor use.
Bullet Cameras
These have an elongated, cylindrical design. They are highly visible and are generally mounted on walls using an articulated arm.
Use: Their primary function is deterrence. Being so visible, they alert others to the presence of surveillance. They are excellent for outdoor use because they typically have better infrared range (night vision) and can be easily aimed at hallways or long perimeters.
Cube Cameras
Small desktop or wall-mounted cameras, usually with Wi-Fi and two-way audio.
Use: For home or small office use. They are ideal for seeing who enters through a door or monitoring a specific room without complex wiring.
Hidden/Pinhole Cameras
Tiny lenses that are concealed within smoke detectors, motion sensors, or walls.
Use: For covert surveillance. They are used in investigations or locations where aesthetics prevent the visibility of a camera, or where internal theft is suspected.
