Dome cameras are versatile, suitable for both indoor and outdoor use, and are often vandal-resistant. Their inconspicuous design makes them ideal for monitoring retail spaces, offices, and public areas without drawing undue attention.Bullet cameras
Bullet cameras are characterised by their cylindrical shape. They resemble a bullet, hence the name. These cameras are designed for long-distance viewing and are equipped with built-in infrared LEDs for night vision capabilities. Bullet cameras are commonly used for outdoor surveillance in car parks, warehouses and perimeter security owing to their robust build and weatherproof design.PTZ cameras (Pan-Tilt-Zoom)
PTZ cameras offer unmatched flexibility and control compared to other CCTV camera types. These cameras can pan (move horizontally), tilt (move vertically), and zoom in on specific areas of interest. PTZ cameras are remotely controlled, which allows operators to track subjects in real-time and zoom in for detailed monitoring. They are often deployed in large areas such as stadiums, airports, and city centres where comprehensive surveillance coverage is essential.Box cameras
Box cameras are traditional CCTV cameras known for their modular design and customisable features. These cameras are highly adaptable, and allow users to interchange lenses to suit different surveillance requirements, including long-range viewing or wide-angle monitoring. Box cameras are commonly used in environments where specific surveillance needs must be addressed, such as license plate recognition or facial recognition applications.Thermal Cameras
Thermal cameras operate based on heat signatures rather than visible light, which makes them ideal for low-light or no-light conditions. These cameras detect infrared radiation emitted by objects and translate it into visible images to enable surveillance even in complete darkness or challenging weather conditions. Thermal cameras are frequently employed in perimeter security, border control, and industrial monitoring where detecting intruders or anomalies is critical.Wireless Cameras
Wireless CCTV cameras eliminate the need for cumbersome wiring. They offer hassle-free installation and flexibility in placement. These cameras transmit video signals wirelessly to a central monitoring system or network, providing seamless integration with existing infrastructure. Wireless cameras are ideal for temporary surveillance setups, remote locations, and areas where running cables is impractical or costly.Covert Cameras
Covert cameras, also known as hidden or spy cameras, are designed to monitor activities discreetly without attracting attention. These cameras are often concealed within everyday objects such as smoke detectors, clocks, or motion sensors, which makes them virtually undetectable. Covert cameras are widely used in undercover operations, nanny monitoring, and in retail environments to deter theft or misconduct.
The diverse range of CCTV camera types available in the market caters to multiple surveillance needs and environments.
Understanding the strengths and limitations of each type is essential for designing effective surveillance systems tailored to specific requirements.
Whether it is safeguarding homes, businesses, or public spaces, the right CCTV camera can enhance security, provide valuable insights, and ensure peace of mind in an increasingly interconnected world.

Factors to consider when selecting CCTV cameras
There are 3 main factors to consider when choosing CCTV cameras: lens, sensor and output.
1. The correct lens
Choosing the correct lens will ensure that you receive a quality image. The right lens enables your camera to focus and bring enough light to the sensor, which helps in recognising licence plates, faces and other identifying information.
A zoom lens can provide more information because optical zoom adjusts the light as it reaches the sensor, which offers flexibility and enhanced pictures.
2. The correct sensor
There are two things to consider when selecting the right sensor: namely, type and size.
CMOS (complementary metal oxide semiconductor)
CCD (charged coupled device) cameras
CCD cameras are more expensive than CMOS; however they produce a clearer image, which makes them suited to identifying more and finer detail.
3. The correct output resolution
The more pixels, the better the picture. The highest resolution you can get is 700TVL but many mainstream cameras range between 300-550TVL. It is important to match a resolution that your camera can produce, as anything more is unnecessary and redundant.
(TVL (Television Lines) is defined as the maximum number of alternating light and dark vertical lines that can be resolved per picture height. A resolution of 400 TVL means that 200 distinct dark vertical lines and 200 distinct white vertical lines can be counted over a horizontal span equal to the height of the picture.)
High Definition (HD) CCTV Cameras Overview
HD CCTV cameras provide unrivalled picture quality that delivers high clarity images. HD CCTV cameras deliver resolutions from 720p up to 4K, which eliminates risks of the subject of recordings appearing grainy or distorted.
