Types Of CCTV Cameras
Security cameras are primarily categorized by their housing (e.g., dome, bullet) or the technology they use (e.g., IP, HD Analog). These types offer a range of features from high-definition remote monitoring to weatherproof, discreet, or expansive area surveillance.
IP Cameras (Network Cameras)
IP cameras transmit video digitally over a network connection, typically via Ethernet or Wi-Fi.
Key Features:
- Resolution: They are known for high-definition video quality, including 2K and 4K resolutions.
- Connectivity: Connect via wired Ethernet for stable power (PoE) and data, or wirelessly via Wi-Fi for easier installation.
- Smart Features: Often include advanced features like AI-powered human or vehicle detection, remote monitoring via apps, and cloud storage options.
- Storage: Support both cloud storage (often with a subscription) and local storage options like NVRs or microSD cards.
HD Analog Cameras (TVI/CVI/AHD)
HD Analog cameras provide high-resolution surveillance while using traditional coaxial cables to connect to a DVR (Digital Video Recorder), making them a cost-effective upgrade for older systems.
Key Features:
- Connectivity: Use existing coaxial infrastructure, which saves on re-wiring costs when upgrading from older analog systems.
- Resolution: Offer resolutions ranging from 2MP up to 4K (8MP), delivering sharp image quality.
- Recording: Footage is stored locally on a DVR, generally avoiding monthly subscription fees.
Dome Cameras
Dome cameras are easily recognizable by their spherical, dome-shaped housing, which makes them discreet and versatile for both indoor and outdoor use.
Key Features:
- Design: The dome shape helps conceal the camera's direction, deterring potential intruders.
- Installation: Can be mounted on ceilings or walls and are available in both fixed and PTZ (Pan-Tilt-Zoom) variants.
- Durability: Many models feature vandal-resistant and weatherproof (IP67) housings.
Bullet Cameras
Bullet cameras have a distinct cylindrical shape and are typically more visible than dome cameras, often used as a deterrent.
Key Features:
- Visibility: Their conspicuous design can help deter criminal activity.
- Usage: Primarily designed for outdoor use with weatherproof ratings (e.g., IP66).
- Night Vision: Often include built-in infrared (IR) illuminators, providing clear black-and-white or color footage in low-light conditions.

PTZ Cameras (Pan-Tilt-Zoom)
PTZ cameras offer dynamic control over a large coverage area, allowing operators to remotely adjust the camera's position and zoom.
Key Features:
- Movement: Allow for horizontal panning, vertical tilting, and optical zooming in on specific details.
- Application: Ideal for monitoring large, open spaces like parking lots, malls, or public areas where real-time adjustment is necessary.
- Automation: Can be configured to follow pre-set patterns or automatically track moving objects using AI

Wi-Fi/Wireless Smart Cameras
These cameras are primarily designed for ease of use in residential settings, offering a balance of smart features and simple installation.
Key Features:
- Installation: Wireless connectivity simplifies setup by eliminating the need for extensive wiring, with many models being battery-powered.
- Audio: Commonly feature built-in two-way audio for communication.
- Smart Integration: Often integrate with smart home ecosystems like Google Home or Amazon Alexa.
Night Vision/ColorVu Cameras
These specialized cameras are engineered to capture high-quality images in challenging or no-light environments.
Key Features:
- IR Night Vision: Use infrared LEDs to capture detailed black-and-white footage in total darkness.
- Color Night Vision/ColorVu: Employ advanced sensors and supplemental white light to provide full-color images 24/7, which is crucial for identifying details like clothing or vehicle colors.
