C-Mount CCTV cameras

CCTV (Closed-Circuit Television) cameras are surveillance systems used to monitor and record activity in a particular area. They are considered one of the most effective deterrents against security threats such as burglaries, intrusions, and vandalism, which is why they have become a common sight in residential and commercial properties.

There are several types of CCTV cameras available, each with its own set of unique features and capabilities. Choosing the right one can be challenging and is a crucial decision to make in terms of your property’s security.

Some of the most popular types of CCTV cameras include:

Read on to find out more about C-mount CCTV cameras, their advantages and disadvantages, how to choose the right CCTV camera for your security needs, and much more:


C-mount CCTV cameras, also called box cameras, are equipped with a detachable lens, allowing the field of view to be adjusted and cover a large area.

They are bigger in size and make for a visible deterrent. They are also extremely durable and come with a rugged casing and weatherproof housing that protect them from external elements and other challenging conditions such as extreme weather conditions and temperature fluctuations.

Depending on the monitoring needs, the detachable lens can be swapped out for different types of lenses and can be used for specialised surveillance.

These features make C-mount CCTV cameras perfect for monitoring purposes, particularly in industries such as food, logistics, and manufacturing where they may be exposed to a harsh environment. They can also be used in large indoor environments such as warehouses and to monitor long stretches of road.


The first security camera introduced in the 1970s was a C-mount CCTV camera. It had a boxy, bulky look and was limited in terms of technology compared to the type of security cameras we have in the market today.

Since the circuit boards and chip sets were much bigger than they are these days, it restricted security cameras to the C-mount camera style. The most common camera style nowadays is the bullet CCTV camera, but for many years, the C-mount style defined the security camera industry.

C-mount CCTV cameras are, to date, a popular choice when it comes to security cameras as their big size makes it easier to support newer technology. When a new technology is developed, it is first created and then made smaller, which is why C-mount cameras are usually the first choice when it comes to new features and technologies.

These cameras come with removable lenses that can be changed to fit different applications. They can cover distances beyond 40 feet thanks to the possibility of using specialised lenses, compared to standard CCTV lenses that can cover a maximum of 35 to 40 feet.

C-mount CCTV cameras work just like any other CCTV camera and are made up of several basic components that include cameras, monitors, a recording device, and system software. The camera works alongside the rest of the components to provide monitoring services.

This is how C-mount CCTV cameras (and all other CCTV cameras) work:

  1. The cameras are installed in strategic locations around the property to cover all the vulnerable points such as the entrances, exits, and car parks.
  2. After being installed, the cameras start taking a sequence of images of the area under surveillance.
  3. The images are then transmitted to the recording device using a cable or wirelessly over a Wi-Fi connection, depending on the type of CCTV camera.
  4. The images are further sent to the connected display monitor in a video format to allow the users of the system to view the live footage. There may be more monitors if the CCTV system is big and has multiple cameras attached to it.
  5. Depending on the type of CCTV camera and its features, there may be the ability to control the camera by zooming in and out and changing the view angle.
  6. If the system is professionally monitored, it works alongside sensors to alert a professional monitoring company of unusual activity in the area under surveillance. This guarantees an immediate response within a matter of minutes.


C-mount CCTV cameras are a great option for those who wish to adjust the field of view according to their security needs. Since they are equipped with detachable lenses, they can easily be swapped to monitor varying angles and distances.

There are several advantages of using C-mount CCTV cameras for monitoring purposes:

Detachable lenses:

Since C-mount CCTV cameras have detachable lenses, it gives the users more flexibility in terms of swapping the lenses according to their needs. Special lenses can be fitted to extend the range of the camera and monitor at distances beyond 40 feet.

Longest range of vision:

C-mount CCTV cameras have one of the longest ranges of vision thanks to the specialised lenses that can be used. This feature is incredibly useful in large, open areas such as long hallways, reception areas, and warehouses.

Highly visible appearance:

C-mount cameras are big and bulky, which gives them a highly visible appearance in order to deter criminals. The mere sight of the camera will scare away potential criminals for the fear of getting recorded on camera.


C-mount CCTV cameras, like most CCTV cameras, have a weakness, which is that they require a lot of effort to be installed outdoors.

Compared to other CCTV cameras, such as bullet cameras, C-mount cameras are more sensitive and can be susceptible to external factors such as rain, heat, wind, and snow.

To use a C-mount CCTV camera outdoors, you will have to purchase a housing and mounting bracket to protect it from rain and projectiles. Some models also come with heaters and blowers to regulate the temperature. The mounting brackets enable them to be mounted on exterior walls.

You also need to keep in mind that C-mount CCTV cameras come lens-free, and you have to choose a suitable lens when making the purchase. Many consider this a benefit as it allows them to customise the camera according to their security needs.


There are several options when it comes to CCTV cameras, with each type offering its own set of benefits. Here is an overview of the types of CCTV cameras (other than C-mount) that you can choose from:

Dome CCTV cameras

Dome CCTV cameras get their name from the dome-shaped casing that the camera sits in. They are used as a hidden deterrent due to their discreet appearance, and because of the dome casing, it makes it very difficult for people to see which direction the camera is looking at. This air of uncertainty gives the cameras an edge and makes criminals wary of approaching areas under their surveillance.

They are most commonly used in shops, restaurants, hotels, and casinos. They are also ideal for indoor surveillance without being too intrusive aesthetically.

Bullet CCTV cameras

Bullet CCTV cameras are one of the most commonly used CCTV cameras out there. They are cylindrical in shape and resemble a bullet, hence the name. They are known for their iconic design and for being a highly visible deterrent.

Their shape allows them to monitor longer distances and their casing makes them resistant to water, dust, and dirt, which is why they are usually the CCTV camera of choice for outdoor surveillance.

PTZ CCTV cameras

PTZ (Pan-Tilt-Zoom) CCTV cameras are known for the flexibility and level of control that they offer their users. With the ability to pan, tilt, and zoom the lens of the camera with a tap on the screen of your monitor, these cameras can easily be adjusted to change the field of view according to your needs.

They are a great choice for remote viewing and are popular in large retail environments. Regarded as the best CCTV camera for businesses that need to protect a specific object, one PTZ camera can do the work of several static cameras!

Day/night CCTV cameras

Day/night CCTV cameras are made specifically to operate in all types of lighting conditions and they work great during both daytime and night-time. They are equipped with extra sensitive imaging chips and can function in direct sunlight, reflections, glare, and poor lighting.

They are the perfect choice for businesses that require CCTV monitoring around the clock in varying lighting conditions.

Infrared/night vision CCTV cameras

Infrared/night vision CCTV cameras, as the name suggests, are designed to work in extremely dark conditions as well. This is made possible through the use of infrared technology which records coloured footage during the day and black and white footage at night.

They are the ideal choice for properties that need reliable surveillance and monitoring despite the lighting conditions. Some common use cases include banks, farms, and manufacturing facilities.

Network/IP CCTV cameras

Network/IP CCTV cameras share live footage over the internet so that it can easily be accessed from anywhere in the world for remote monitoring. The footage is compressed to make data transfer easier, and the archived footage is stored on network video recorders (NVRs) or secure software.

They are a good choice for business owners who are often away from the site and need access to the footage via a smart device such as a mobile phone, PC, or laptop.

Wireless CCTV cameras

Wireless CCTV cameras minimise the use of cables and are much easier to install than wired systems. They have a much cleaner appearance and a less obstructive installation process. Like IP cameras, their footage can be transmitted over the internet to be viewed anywhere.

Due to their tidy appearance, they blend into the interior and are commonly used in churches, museums, stately homes, and anywhere where the appearance and aesthetics of the camera matter.

High-Definition (HD) CCTV cameras

High-definition (HD) CCTV cameras, as the name suggests, offer unparalleled picture quality and deliver high-definition footage in perfect clarity. Depending on your budget, you can choose between several options ranging from 70p up to 4K.

This functionality is available in most CCTV models such as dome and bullet cameras and helps with criminal identification.


With so many options to choose from, you must make the right decision and install a CCTV camera that provides the maximum level of security.

Certain types of CCTV cameras are perfect for certain conditions and completely wrong for the other. For example, installing an indoor camera for outdoor use will not give you the results you are looking for. Similarly, for night-time surveillance, you must choose a system that is capable of recording footage despite the low-light conditions.

To make the decision-making process easier, you need to keep a few factors in mind such as:

The area you need to monitor

This is probably the most important thing to consider as it will determine where exactly the camera needs to be placed. If the area is outdoors, you must go for a system that can withstand the outdoor environment. For a large area indoors, you need to choose a system that supports a wide-angle lens and can be adjusted for the best view.

Discreet or visible deterrent

CCTV cameras can be discreet or visible depending on their shape and size. Both are effective deterrents, but which one you choose is based on your particular security needs. If you want a visible deterrent, you must opt for a system that can be seen by people, such as a bullet camera.  If you wish to hide the camera and go for a discreet system, a dome CCTV camera may be a better choice.

Resolution of the camera

CCTV cameras come in a range of resolutions, which is what determines the quality of the footage produced. The higher the resolution, the better the picture quality. If you want the footage to be clear enough to be able to identify people and objects in it with ease, it is best to invest in a high-resolution camera instead of a low-quality one with pixelated results.


If you plan on renovating or expanding your property in the near future, you must invest in a CCTV system that is scalable and supports growth plans. Wireless IP cameras are a better option compared to wired CCTV cameras in terms of changes, adjustments, and scalability.

A few other features that you need to look for when choosing the right CCTV camera for your property include:

To get the most out of your C-mount CCTV camera, you must have it installed by a skilled and certified professional. A professional installer will not only help you choose the right CCTV camera for your security needs but also determine the ideal installation position to capture the best angles.

It is also very important to regularly maintain the CCTV camera to make sure it keeps working as it should. Regular maintenance includes the users keeping the system clean by gently wiping it with a cloth and removing any obstructions, as well as professional maintenance which involves a system specialist servicing the camera and all of its components to minimise any potential issues from arising.
