A dome CCTV camera, enclosed in a dome-shaped housing, is discreet, versatile, and ideal for indoor and outdoor use. Many models are also durable, vandal-resistant, and weatherproof.
It conceals its viewing direction, enhances security, offers a wide field of view, and often includes features like night vision, motion detection, and PTZ capabilities.
A turret (or eyeball) CCTV camera is a type of surveillance camera with a compact, ball-shaped design that allows for flexible positioning. The camera's lens is mounted on a swivel base, allowing it to be easily adjusted to cover a wide area.
These cameras are commonly used in security systems for their ease of installation, versatiliy, and durability.
Bullet CCTV cameras are sleek, cylindrical surveillance devices resembling bullet shells. They are durable, weather-resistant, and suitable for both indoor and outdoor use. Commonly mounted on walls or ceilings, they focus on specific areas and are ideal for monitoring open spaces. Features often include night vision, motion detection, and high-resolution video capture.
Multi-sensor cameras use multiple sensors to capture different angles and create a seamless view. It's ideal for monitoring large areas while eliminating blind spots.
Panoramic cameras offers wide-angle coverage of 180° to 360°, using fisheye lenses, ultra-wide sensors, or multiple stitched sensors. It's perfect for monitoring open spaces efficiently.
A PTZ camera offers horizontal rotation (pan), vertical movement (tilt), and zoom capabilities, providing detailed and flexible video surveillance. They are often controlled remotely, allowing operators to focus on specific areas or track moving objects in real-time.
PTZ cameras are widely used in high-security environments like airports, shopping centers, or traffic monitoring.
A fisheye camera has a wide-angle lens that captures 180° or 360° panoramic views, creating a hemispherical image. These cameras provide broad coverage, eliminating the need for multiple cameras, and are ideal for monitoring large areas like car parks, hallways or lobbies.
They are commonly ceiling-mounted to offer a comprehensive, distortion-free view of the environment.
A thermal imaging camera detects infrared radiation (heat) emitted by objects and converts it into an image showing temperature variations, these images are called thermograms.
Thermal cameras can see in complete darkness, low visibility conditions and through obstructions, making them useful for detecting heat sources, body temperature, and issues like electrical faults, and fire hazards.
An ANPR camera (Automatic Number Plate Recognition) captures and reads vehicle licence plates. It is helpful because it can work 24/7, even in low-light conditions, and can process a large number of vehicles quickly.
ANPR can be used in traffic management, parking enforcement, toll collection, and security systems to identify and track vehicles efficiently and accurately.
CCTV resolution is important because it affects the clarity and detail of footage. Higher resolution provides clearer images, making it easier to identify faces, licence plates, and small objects. It allows for better zooming and cropping without losing quality, improves monitoring, and provides more reliable evidence in legal situations, enhancing overall security and efficiency.
Security camera resolution is typically measured in megapixels (MP). Common options include 2MP, 4MP, 5MP, and 8MP, with some cameras offering higher resolutions like 10MP, 12MP, or even 20MP.
Field of View
Field of view in CCTV refers to the area a camera can capture or "see" within its lens. It’s the extent of the observable scene that the camera can record, typically measured in degrees (horizontal, vertical, or diagonal).
A typical field of view is around 90 degrees. Other factors influencing the field of view include the lens type and its size.
IP or Analogue Cameras
The main difference betweenIP (Internet Protocol) and analogue CCTV cameras lies in how they transmit and process video data.
IP CCTV Cameras provide higher quality, scalability, and advanced features, making them suitable for modern, large-scale, and flexible surveillance systems.
Analogue CCTV Cameras, while more cost-effective, offer lower resolution and are better suited for smaller or budget-conscious installations.
The main difference between fixed and varifocal lenses is their adjustability.
Fixed lenses have a preset focal length and a fixed field of view, making them ideal for areas requiring consistent coverage.
Varifocal lenses allow you to adjust the zoom and field of view, offering flexibility for areas that need varying focal points. They are generally more expensive due to the added functionality.
Fixed lenses are cost-effective for stable coverage, while varifocal lenses are better for dynamic or adjustable surveillance needs.
Weather Rating
CCTV cameras' weather resistance refers to their ability to withstand outdoor environmental conditions, such as rain, dust, heat, cold, and humidity.
The level of weather resistance is measured using an Ingress Protection (IP) rating, which has two numbers:
The first digit indicates protection against solid objects (i.e, dust).
The second digit indicates resistance to liquids (i.e, water).
An IP66 rating is recommended for outdoor use, ensuring the camera is dustproof and protected against strong water jets. Higher ratings, such as IP67 or IP68, offer even greater resistance to water.
A DVR is used for analogue systems, while an NVR is for IP-based systems, providing more flexibility and higher-quality footage.
DVR works with analogue cameras that use a coax cable for video transmission, converting the analogue signal to digital for recording. It's commonly used in older, budget-friendly systems.
NVR works with IP cameras that transmit digital video over a network, offering better scalability and higher video quality. It can use existing network infrastructure, including Ethernet or Wi-Fi.
AI CCTV cameras use artificial intelligence to enhance surveillance systems by enabling automatic detection, analysis, and interpretation of events or behaviors.
Facial Recognition: Identifies and matches faces for real-time recognition.
Object Detection: Detects and classifies objects like vehicles or people.
Behavioural Analysis: Identifies suspicious activity, i.e, loitering or unauthorised access.
Motion Detection: Filters out false alarms, focusing on relevant movements.
Licence Plate Recognition: Reads vehicle plates for tracking purposes.
Crowd Management: Analyses crowd size and behaviour to detect overcrowding or risks.
Smart Search: Enables efficient searching of video footage for specific events or objects.
Video Storage
Storage is a crucial element of video surveillance systems, enabling the retention of recorded footage for extended periods, often lasting months.
The duration of storage depends on factors such as resolution, number of cameras, frame rate, compression rate, and more. It’s important to ensure the system has sufficient storage capacity to meet your desired video retention needs.
When setting up a CCTV system, choosing the correct cables is essential. For IP security camera systems, use network cables like CAT5e or CAT6 Ethernet, which can transmit both power and data via a single cable. However, if the cameras aren't Power over Ethernet (PoE), a separate 12v power supply is required.
For analogue or HD cameras using coaxial cables, RG59 Shotgun cable is necessary to transmit video and supply power. Alternatively, HD cameras over coax can be adapted to network cables with a video balun—an efficient option if the site already has Ethernet cable installed, saving time on new cable installation.
When planning the placement of CCTV cameras, there are several important factors to consider to ensure you get optimal coverage, security, and effectiveness. Find out more about in this episode of Norbain Basics.

Choosing between IR and white light CCTV cameras depends on specific security needs. IR is more suitable for discreet, low-light surveillance, while white light cameras are better for areas where colour footage is a priority.
A PTZ (Pan-Tilt-Zoom) camera is a type of CCTV camera that can move horizontally (pan), vertically (tilt), and zoom in or out. These features allow it to cover a large area, reducing the need for multiple static cameras. PTZ cameras are commonly used in security systems for large spaces like car parks or stadiums, and can be controlled remotely or set to follow preset patterns.
How long is CCTV footage kept UK?
In the UK, CCTV footage retention varies depending on the organisation and its purpose, but it is typically stored for 30 days. The retention period is influenced by legal requirements, privacy concerns (under the Data Protection Act 2018 and GDPR), and the purpose of the surveillance. Footage may be kept longer if needed for investigations.
Organisations must have clear policies to ensure compliance with data protection regulations while addressing security needs.
What does CCTV stand for?
CCTV stands for Closed-Circuit Television. It refers to a system of video surveillance cameras used for security purposes, where the video feed is transmitted to a limited number of monitors or recording devices.
