Wondering which CCTV security camera is best for your business or home?
We’ve put together a comprehensive security camera guide. From the most common camera types to the various in-built technologies, this go-to guide delivers all the essential info in one easy-to-understand article.
Here’s everything you should know before investing in a security camera system.
Types of Security Cameras
A bewildering array of CCTV security cameras are available these days, from fixed systems to fish eye cameras and Wifi-enabled devices. Each security camera type suits users with specific needs.
PTZ Security Cameras
An acronym for pan, tilt and zoom, the PTZ camera offers a wide viewing area and optimal control. Some variations don’t perform all three functions—a PT camera can pan and tilt but won’t zoom.
Most PTZ cameras are remote-controlled, requiring a human to pan, tilt, and zoom. Smart PTZ cameras can be used via a mobile app, while analogue versions use a custom-built keyboard and joystick. A select few high-tech options don’t require human intervention. These use motion sensors to automatically track movement or a timer to focus on specific areas at certain times.
With viewing angles of up to 360 degrees, these versatile solutions are common in properties with high security requirements. Sensitive areas like airports, ports, and power plants readily adopt PTZ technology.
Fixed Security Cameras
Fixed security cameras can’t do any of the above functions—you won’t be able to pan, tilt, or zoom. The only way to move a fixed camera is by physically adjusting the direction of the lens on the mounting bracket.
This simplified solution is cheaper than the PTZ camera, making it a cost-effective alternative for properties with lower security requirements. This ubiquitous camera type appears in various places, from residential homes to hotels and retail stores.
Fisheye Security Cameras
The fisheye camera is a flat, bubble-shaped device with an ultra-wide-angle lens. This tech makes it capable of capturing dynamic viewing angles, anywhere from 180 to 360 degrees.
The wide image provides greater situational awareness and can eliminate blind spots without installing a separate camera—a great cost-saving measure. Despite its warped image, the fisheye camera is a top option for indoor areas like retail stores and transport terminals.
Panoramic Security Cameras
Also known as 360-degree or multi-sensor cameras, panoramic security cameras are popular for their extra-wide viewing angles. The device combines input from separate sensors into one image, much like using panoramic mode on a smartphone camera. Combined with high-definition imagery, it’s possible to tilt, zoom, and pan digitally.
Panoramic security cameras don’t suffer from distortion, unlike a fisheye lens. The device is best for outdoor areas where identifying people can prove difficult, such as parking lots and public plazas.
Bullet Security Cameras
The bullet camera is named for its cylindrical, bullet-like shape. As they point directly forward, this camera type offers a limited field of view, making it suitable for covering small areas and exit/entry points. A lip provides weather protection for outdoor use.
One of the key bullet camera benefits is its highly recognisable design creates a potent deterrent. On the downside, limited viewing angles mean you may have to add supplementary cameras, and the conspicuous shape makes them vulnerable to vandalism.
Dome Security Cameras
Dome cameras are also named after their shape; it’s got a smooth, rounded figure that’s more discreet than a bullet camera.
These devices offer better viewing angles than bullet cameras, but not as wide as panoramics. As they’re harder to identify, dome cameras don’t provide such a powerful deterrent. On the plus side, they’re less obvious, thus less likely to be vandalised.
Dome cameras are most commonly used indoors (they’re often called ceiling cameras), especially in small rooms like shops and offices. Outdoor use is also viable.
Turret Security Cameras
The turret is a popular CCTV security camera type featuring a small lens in a ball and socket design. The ball-shaped lens has a three-point axis to pivot inside the socket, somewhat like a turret—hence the name. This feature makes installation easier, as you can mount the camera in any direction and aim the lens as desired.
Turret cameras are inconspicuous and vandal-resistant, although not quite to the extent of a dome camera. As they have less glass, you won’t have as many infrared (IR) glare issues, which occur when dust and grime bounce IR light back into the lens.
Turrets are a popular option among residential and commercial properties, both indoors and out. Thanks to a wide aperture and large image sensor, they work well in low-light conditions.
Video Intercom
Also known as a video door phone, the video intercom incorporates real-time images into an intercom system. A camera near an entry point transmits images to a wall-mounted panel inside, so the occupants can identify their visitors. Many video intercoms can also send footage to a mobile app, allowing it to be monitored anywhere in the world.
A two-way audio feature lets the user converse with their guest and vice versa. Some come with a remote locking feature, which enables the user to unlock/lock a door with the push of a button.
Wireless Security Cameras
A wireless security camera transmits images via a local Wi-Fi network; thus, they’re sometimes known as Wi-Fi cameras. Wireless cameras store images on a local memory card or an online cloud storage service, though the latter often entails a monthly subscription fee.
Many use motion sensing technology to automatically capture images upon detecting movement. When this happens, users receive an instant mobile app notification or email to alert them of a potential threat.
Most wireless camera systems connect to the mains power through a cable; “wireless” only refers to their ability to transmit data via the internet. Some options are battery-powered for a truly wireless experience. However, limited battery life means these cannot record continuously, so you must rely on motion sensors instead.
The benefits of going wireless include a cheap, easy installation as well as scalability and flexibility. On the downside, they’re not as fast, secure, or stable as wired systems, and the image quality generally isn’t as good.
Solar-Powered Security Cameras
Solar-powered cameras are an innovative security solution for remote areas without access to mains power. The system entails a tower with a camera and solar panels perched on top, often attached to a dolly for optimal portability. An in-built battery stores power for cloudy days and nighttime use.
Many solar-powered cameras transmit captured images by the local 4G network. When 4G isn’t available, a wireless bridge provides stable cable-free data transmission over large distances. Solar-powered systems can incorporate various camera types and capture clear imagery from 100 to 500 metres away.
The technology is primarily used in industrial and public infrastructure projects, such as oil and gas fields, construction sites, and telecommunication towers.
Security Camera Technology Options
Most of the aforementioned camera types can include an array of state-of-the-art features. All these options are available from Hikvision, a global leader in the security camera industry.
Dock Management Cameras
Dock management cameras optimise efficiency in logistics operations such as cargo docks and distribution centres. Always-on video surveillance helps track lost or damaged goods and monitor entry/exit points.
Dock operation, loading rate, and rear door status detection allow businesses to enhance efficiency. ANPR technology keeps a real-time record of every vehicle on the premises.
Colour at night with Colorvu
ColorVu is a state-of-the-art technology using an advanced sensor, an ultra-wide F1.0 aperture, and image processing to capture vivid full-colour footage at night.
Panoramic cameras stitch together a wide field of view with high-definition detail.
Low light imaging with Darkfighter
Darkfighter technology uses dual sensors and bi-spectral fusion technology to capture sharp colour images in low-light conditions.
ColorVu is the preferred option for recording dimly lit areas within a 20-metre radius. Darkfighter, on the other hand, works better over longer distances.
Intrusion Detection with AcuSense
AcuSense is a potent AI-powered intrusion detection system. The technology differentiates people and vehicles from other potential threats, enabling security teams in heavily-trafficked areas to operate more efficiently.
AcuSence can also detect intruders in real time and send instant alerts to designated personnel.
Perimeter Protection
Perimeter protection solutions safeguard properties against intruders. Tiered options are available for short, medium, and long perimeters, each with distinct configurations to optimise security.
AcuSense technology uses AI to classify targets, while HeatPro series thermal cameras identify intruders in any light conditions and activate an alarm.
People Counting
People counting technology can be incorporated into a security camera system to improve queue management and flow control. The innovation lets management understand visitor numbers, peak occupancy periods, and congregation or movement trends.
This information can be used to improve operational efficiency, plan future events, and take immediate action against potential threats.
Heat Mapping
Heat mapping is a hit among retail managers for its ability to monitor shopping habits.
The technology tracks customer movement and provides a clear colour-coded map outlining the amount of time shoppers spend in specific sections of a store. This data lets management identify dead zones and alter their in-store layout to optimise sales.
Thermal Cameras
A thermal camera uses special infrared sensors to detect the temperature difference between objects within its line of sight, even in complete darkness. The sensor converts data into imagery, enabling users to identify living objects and other heat-emitting sources in real time.
A wide range of professionals use thermal cameras, including first responders, electricians, mechanics, animal welfare managers, and security teams.
Facial Recognition
Facial recognition technology records a human face and compares its features against an image database in real time. The identification process takes under a second, making it more efficient than traditional methods like passwords and fingerprint readers.
Organisations can incorporate facial recognition to streamline access control, monitor attendance, and track customer behaviour.
Vehicle Identification
Vehicle identification systems use Automatic Number Plate Recognition (ANPR) cameras to record number plates, as well as other details such as the make, model, and colour. This fast and reliable process reduces manual labour costs, speeds up traffic flow, and minimises driver wait times.
Vehicle identification is especially effective in busy commercial car parks, distribution or docking centres, and for traffic violation services.
Network Video Recorders
A network video recorder (NVR) is a custom-built computer designed to record video footage digitally and save it to a hard drive. An NVR connects to external CCTV security cameras, which transmit data via Wi-Fi or an Ethernet cable.
NVRs have largely replaced the outdated Digital Video Recorders (DVR) of the past. The newer system can be wired or wireless and only requires one cable for video, audio, and power. High-quality images enable cutting-edge functions like ANPR and facial recognition, while PTZ camera controls let the user tilt, pan, and zoom.
Security Cameras for Business
The best security camera for business use depends on a broad range of factors, including the industry, property type, risk, and asset value. Sensitive areas will benefit from high-tech options like PTZ cameras and ColorVu, while small retail stores could settle for a simple dome camera setup.
