CCTV cameras have become an integral part of security, with homeowners and business owners alike realising their benefits and installing them on their properties.
They act as one of the biggest deterrents for burglars, with former professional criminals saying that they would prefer not to target properties with a CCTV system in place.
Also, the footage captured by the cameras makes catching the criminals much more accessible and can also be used as evidence in a court of law.
In addition to providing great security benefits, using well-maintained CCTV systems makes you eligible for a reduction in your insurance premiums as well.
Ever since their inception in the mid-twentieth century, they have grown in popularity with various types of CCTV cameras available now.
It can sometimes become quite challenging to choose the best one for your requirements with the plethora of choices. However, it must be understood that it isn’t a ‘one size fits all type of scenario.
The different types are made for specific purposes, and to achieve the highest level of effectiveness, it is detrimental that the correct type of CCTV camera is used. For instance, there’s no point in using a camera for night-time surveillance that doesn’t have night vision.

Types of CCTV Cameras
There are various CCTV cameras to choose from, varying in their specific features and unique options.
A good CCTV camera makes sure it captures clear footage irrespective of the time of day, light availability, or extreme weather conditions.
You must ensure you have the right kind of system installed on your premises to guarantee effectiveness and efficiency. The most popular types of CCTV cameras include:
- Bullet CCTV cameras
- Dome CCTV cameras
- C-Mount CCTV cameras
- PTZ Pan/Tilt/Zoom cameras
- Day/Night CCTV cameras
- Infrared/night vision CCTV cameras
- Network/IP CCTV cameras
- Wireless CCTV cameras
- High Definition (HD) CCTV cameras
Let’s look at each one in detail:
Bullet CCTV cameras get their name from their long cylindrical bullet-like shape and are one of the most common CCTV cameras.
Bullet Cameras have a long and tapered cylinder-like design that resembles a large ammo cartridge.
They are mainly used outdoors, especially in areas where extended viewing is necessary. However, they can be used indoors where an extended viewing is required, like backyards and parking lots.
They are installed inside protective casings and are typically weatherproof. Most bullet cameras come with a fixed length that allows up to 80 degrees of view. In addition, a bullet camera is usually fitted with a fixed or varifocal lens.
Bullet cameras are used in applications that require long-distance viewing and are usually found in open spaces that include parking lots, back and front yards, shopping malls, offices, factories, warehouses, and farms.
- Long-distance surveillance up to 40 Ft
- Outdoors weatherproof surveillance
- Highly visible so acts as a deterrent
- Resistant to dirt in challenging environments
- Provides surveillance over long distances
- The casing also protects against glare and rain
Bullet cameras can be used to good effect in a range of industries such as manufacturing, property management and farming. They not only record good quality pictures but also send out a message to passers-by that your premises are under surveillance. That’s why they have traditionally offered the best CCTV for outside operation.
Dome Cameras are named after their shape and are typically used for indoor security systems.
The dome shape of these cameras allows them to be inconspicuous because it is hard to tell the direction the cameras are facing; however, being still visible to the eyes. As a result, they are widely used in retail spaces.
Since they are installed on the ceiling of the room, they are mostly vandal proof. In addition, some dome cameras are designed with infrared illuminators, which enable them to capture videos in low light conditions.
Dome CCTV camera gets its name from the dome-shaped casing that the camera sits in. Whilst these are relatively discreet CCTV cameras in appearance, this doesn’t stop them from deterring criminals.
The dome casing makes it difficult for people to see which direction the camera is pointing. This creates an air of uncertainty for potential thieves or vandals approaching from all directions.
- Video Surveillance in Retail Stores and Offices
- Unobtrusive design means it’s easy to fit
- Suitable for indoor and outdoor use
- A vandal-resistant dome means it is harder to interfere with the camera
- 360-degree rotation of the camera so you can cover all angles
This is the best CCTV camera for shops, restaurants, casinos and hotels because the design allows you to monitor a wider angle at your premises.
Many also consider this option the best indoor CCTV camera as it can be placed on a strategic point of the ceiling to cover all angles of the room.
C-mount CCTV Cameras
C-Mount cameras come with detachable lenses that can be switched to adapt to the distance and field of view.
A standard CCTV lens covers around 35 to 40 feet of distance; however, if you wish to cover distances beyond that, you can extend the range of viewing and recording by using special lenses that can be zoomed in and out without losing focus.
They are bulkier in size and noticeable to passers-by, making them an effective visual deterrent to criminal activity.
In addition, they come in a rugged camera casing that protects them from harsh weather conditions, making them suitable for outdoor use.
C-Mount cameras can use detachable lenses to suit different purposes. Typically, a CCTV Camera can record up to 35 feet; however, a C-Mount Camera with a particular lens can achieve that purpose if you need surveillance beyond this distance.
A varifocal lens is often used to fine-tune focal distance and the angle of view. As a result, they can be zoomed in and out without losing focus.
- To achieve variable zoom in surveillance.
- Special lenses can be fitted to the camera to extend its range beyond 40 feet
- The obvious appearance that deters criminals
- Rugged camera casing can be added to protect the camera in cold environments
- Weatherproof housing makes it ideal for outdoor use
This is the ideal camera for observing a stretch of road on the approach to your premises. It is therefore popular in the utilities and logistics industries.
Those operating in the food and manufacturing industries may also elect for this option due to the camera’s reliability in extreme temperatures.
Day/Night CCTV Camera
Day/night cameras are explicitly built to effectively work during the day and night-time, regardless of the lighting conditions.
They have extra sensitive chips that help capture clear and crisp images even at night, due to which they are great for 24/7 outdoor use. In addition to poor lighting, they can also withstand direct sunlight, glare, and reflections.
Ideal for business premises that require round-the-clock CCTV monitoring, day/night cameras record in both colour and grayscale and come in a protective casing to withstand all sorts of outdoor conditions.
These types of CCTV cameras can be used in both poorly lit and standard environments. Primarily used outdoors, these surveillance units have a wide dynamic range and can function under direct sunlight, glare, or reflections.
Keep your vigilance over your home or establishment around the clock with Security Systems’ list of security monitoring services.
They are used 24×7, and these cameras do not require an infrared illuminator as they come with an extra sensitive imaging chip used in the dark.
- For 24×7 surveillance
- Often in low light conditions
- Clear recording in low light
- They usually record in both colour and black and white
- Can function despite glare, direct sunlight, reflections and poor lighting
- The casing protects the camera against the elements for outside surveillance
Various CCTV camera types are suited to outdoor use, but the extra sensitive imaging makes this unique.
It is, therefore, the ideal CCTV system for business premises that require clock CCTV monitoring in an outdoor environment with varying light conditions.
Infrared/Night Vision CCTV Cameras
Night vision CCTV cameras use infrared technology to record images and videos in absolute darkness.
They are usually more expensive than day/night cameras since they can work in pitch-black darkness.
However, they can also withstand fog, dust, and smoke and record coloured footage during the daytime while capturing black and white during the night.
Due to their optimal night-time functionality, they are used by those who need very reliable surveillance even in complete darkness, such as banks, manufacturing plants, and farms.
When we need to see what’s happening in the dark, then a night-vision CCTV camera can help us. It can see when lighting is deficient or in absolute darkness.
The technology behind this is Infrared LEDs. Do you need this kind of CCTV Camera?
- Infrared LEDs allow clear recording even in pitch-black environments
- An infrared cut filter activates in the daytime for clear images in lighter conditions
- Can capture images even in the presence of fog, dust or smoke
- Records colour imagery in the day and black and white at night
This is the best CCTV camera for night vision functionality. It’s, therefore, the ideal choice for those who need ultra-reliable recording in complete darkness—for example, banks, farms and manufacturing plants.
Network/IP CCTV Cameras
IP (Internet Protocol) cameras are connected over a network that allows the live footage to be accessed from anywhere in the world via the internet.
All modern CCTV systems use IP cameras because of their ease of video sharing and remote monitoring.
In addition to sharing the live feed, they also allow storing archived footage on network video recorders (NVRs) and digital video recorders (DVRs).
They are an ideal choice for home and business owners who are often away or on the move since the easily accessible footage gives them the ability to view the footage from absolutely anywhere.
All you need is an intelligent device such as a phone, tablet, or laptop and a good internet connection.
The IP camera can transmit recordings over the internet. Therefore, it may or may not require a wire connection.
Yes, it also works on wireless technology. In comparison to the analogue camera, it is easy to install. It is possible to send recordings over a far distance without requiring any power boost using a cable.
- Footage can be viewed online from anywhere in the world
- Easily accessible archive footage
- Easy setup as coaxial cables and a computer station are not required
- Low maintenance
A network or IP CCTV camera is the ideal choice for business owners who are often away from the site and on the move.
Footage can be viewed from anywhere in the world, via a PC, laptop or mobile phone.
Wireless CCTV Cameras
Wireless CCTV cameras were made for the sole purpose of minimising the installation time and use of excess wires for a cleaner appearance.
Due to their discreet appearance, they easily blend in with the surroundings working as a hidden deterrent.
Therefore, they work best when the excellent presentation is critical. The display of excess wires might ruin the aesthetics, such as in museums, churches, heritage sites, and other tourist attractions.
We have talked about wireless IP cameras. Other types of CCTV cameras are also available that work on wireless technology. Flexible installation is one of the primary benefits.
There are several CCTV camera types with unique features for different purposes. For example, if you are in the market for a security measure, CCTV cameras are an excellent way to ensure surveillance in your home or business space.
- Easier to install than your average CCTV system
- Discreet and tidy appearance and a less intrusive fitting
- Images transmitted over the internet so can be viewed anywhere
- Secure storage and easy access to archive footage
If a spotless presentation is essential in your industry, wireless CCTV cameras are a great security option.
Their discreet appearance helps them to blend into the interior. What’s more, there is less setup and camera maintenance required, and footage is transferred via the internet for convenient access.
High Definition (HD) CCTV Cameras
HD CCTV cameras come in various resolutions ranging from 720p going all the way up to 4K. Quite obviously, the higher the resolution, the better the image and video quality, though compression has a big part to play in that too.
CCTV cameras with low-resolution record footage appear blurred, grainy, or distorted, sometimes making it difficult to identify objects and faces.
HD cameras offer unparalleled video quality and deliver high-quality images with zooming capabilities.
They prove to be particularly useful in high-risk areas where foot traffic needs to be monitored closely. This way, in case of a theft, the perpetrator can be easily identified and caught using the recorded footage.
HD CCTV Cameras can record at high frame rates and HD quality, which is comparatively higher resolution than other CCTV Cameras.
Therefore, this type of camera can capture finer details while giving the operator the option to zoom in without losing picture quality.
- At highly niche places, HD CCTV cameras work well, e.g., casinos and banks
- Casino managers often check if a player is counting cards or not through this camera
- High definition pictures capture subjects in perfect clarity
- Extra clarity can also be achieved with zoom function
- Available on most CCTV models such as domes and bullets
- Crystal explicit imagery provides undeniable criminal identification
High definition cameras are handy for use in environments where there is an increased risk of theft. Businesses such as banks and casinos should opt for HD cameras to ensure that visitors to their premises are captured in perfect clarity.
In addition, the footage recorded will provide undeniable identification in the event of a crime being committed.
Pan Tilt Zoom (Ptz) Camera
It is possible to pan, tilt, and zoom PTZ cameras. It gives a surveillance operator the freedom to pan, tilt, and zoom the lens.
You can manually control these cameras or program them to follow an accurate view of things. Since these cameras can be monitored using live controls, they are employed in susceptible zones where live monitoring is required.
- Expensive PTZ Cameras are to achieve responsiveness.
- Optical zoom on these cameras means you can focus closely on subjects
- Pan and tilt feature provides a 360-degree field of vision
- Image resolution is usually impeccable so that facial features can be distinguished
- Security team have complete control of recording and can react to live situations
This is the best CCTV camera for remote viewing. It is prevalent in large retail environments and is regarded as the best CCTV for business premises that have a specific valuable object to protect.
For example, a museum could program the camera to pan to a particular entry or exit point when it detects movement.
So even when it is not being controlled remotely, the camera can cover a much larger area and do the same job as several static cameras.
