CCTV security cameras come in various shapes and sizes, serving numerous purposes that help to enhance your overall security. However, finding the right option can feel overwhelming when there are so many possibilities to consider. Read our helpful guide to understand the differences in CCTV security camera types.
Common CCTV Security Camera Types
CCTV security cameras are available in various configurations, making them suitable for a wide range of applications. Whether you wish to secure your home or your large factory complex, there is a CCTV system for you.
Analogue CCTV Security Cameras
Before the rapid digitalisation we see today, most CCTV cameras used analogue systems over coaxial cables. The CCTV security camera captures an analogue video signal and transmits it via a coaxial cable to a digital video recorder (DVR). Analogue systems remain in use today for their cost-effectiveness and may include additional features that enhance surveillance capabilities. They may also be compatible with existing, older systems, making these analogue CCTV security cameras easier to set up and install. However, they typically have lower image quality, which can affect overall security and surveillance in situations where clarity is necessary.
Wired CCTV Security Cameras
Unlike analogue systems, modern wired CCTV cameras use Ethernet cabling to transmit video signals to a network video recorder (NVR) over a secure Internet connection. They typically come equipped with the latest technologies, including high-definition resolution for clear visual capture, and may also feature decent interference resistance to maintain a consistent video signal at all times. However, they may require additional work to install and remove Ethernet cables when repositioning cameras.
Wireless CCTV Security Cameras
Wireless CCTV security cameras transmit audiovisual footage to a DVR over a secure Wi-Fi connection, which typically requires far less infrastructure than wired CCTV solutions. Modern wireless CCTV systems enable easier installation and deployment by eliminating cabling and allowing multiple cameras to be added without disassembling existing infrastructure. However, wireless cameras are prone to signal interference, which can degrade recording quality and affect overall security and surveillance.
Hybrid CCTV Security Cameras
While rarer, hybrid CCTV security cameras combine the functionality of different CCTV types to offer a more comprehensive surveillance solution. Some hybrids may prioritise specific features over others, such as high-speed connectivity and advanced facial recognition, but these systems tend to be costly to deploy due to the professional-grade installation needed.
Common CCTV Form Factors
CCTV security cameras also come in various physical forms to enhance your property’s overall surveillance coverage.
Dome Cameras
One of the more common camera types, these cameras are typically ceiling-mounted fixtures featuring a wide-angle lens placed inside a clear dome-shaped enclosure. The dome protects the camera from physical damage and harsh weather. They provide decent audiovisual coverage thanks to their built-in wide-angle lens, while also serving as a subtle or overt security deterrent. Their one downside is the difficulty of disassembling and repositioning them once installed.
Pan, Tilt, Zoom (PTZ) Cameras
PTZ cameras are remotely operated cameras that provide 360-degree audiovisual coverage via on-demand panning, tilting, and zooming from a central control interface. This system helps reduce the need to install multiple cameras and is typically chosen to cover important locations that require continuous surveillance. However, most PTZ cameras lack wide-angle coverage, which means you have to manually or automatically adjust them for sufficient surveillance.
Bullet Cameras
These cylindrical, bullet-shaped devices are typically selected for their recognisable, easily viewable security deterrent and their impressive zoom capabilities for monitoring outdoor spaces or long corridors. Despite their decent surveillance capabilities, bullet cameras are easily vandalised due to their protruding design, which may require additional investment into tamperproof technologies to minimise the frequency of costly repairs. Most bullet cameras are limited to a single field of view, though newer models offer limited pan-and-tilt functionality to overcome this limitation.
Turret Cameras
Turret cameras feature a camera mounted on a ball-and-socket joint that can be remotely controlled to view multiple angles, providing reliable coverage of both indoor and outdoor spaces. Their ability to track movements from various angles at high definition quality enables them to easily monitor high-traffic locations, especially when placed in a strategic yet discreet position. However, they can still be tampered with if noticed, and will require additional support to prevent tampering or vandalism.
Additional CCTV Security Camera Features
Your choice of CCTV security camera may also be influenced by features that add extra capabilities to enhance overall surveillance.
Infrared/Thermal Imaging
Standard CCTV cameras are not designed to monitor pitch-black areas, including outdoor areas at night, so additional night-vision capabilities are necessary. Infrared cameras detect infrared radiation emitted or reflected by objects, enabling them to capture detailed audiovisual data even in dark conditions. There is also thermal imaging, which instead detects thermal radiation (temperature variations) and converts it into visible audiovisual data.
Cloud-Based Recording
Instead of relying on physical DVRs and servers to store security footage, many modern CCTV systems now use a cloud-based solution to manage your surveillance needs. Cloud-based solutions offer a fully configurable security surveillance system that is always online and accessible from anywhere, at any time. This helps reduce your overall expenditure on physical infrastructure, as everything can be managed from a convenient online platform that scales to your needs. Cloud-based solutions also offer robust cybersecurity measures to protect your surveillance network from external intrusions that could compromise your property’s safety.
