Infrared/night vision CCTV cameras

CCTV cameras have been around for quite some time and have made their way into our everyday lives thanks to their security benefits. Previously seen only in a select few places, they have now become a common sight in homes, businesses, and public spaces.

An effective deterrent against security threats such as burglaries and intrusions, CCTV cameras are among the top security systems used in both residential as well as commercial properties.

There are a variety of CCTV cameras to choose from. They include:

In this article, we will discuss all about infrared/night vision CCTV cameras, how they work, their advantages and disadvantages, and how to choose the best infrared/night vision CCTV camera for your security needs:

WHAT ARE INFRARED/NIGHT VISION CCTV CAMERAS?

Security needs to be round-the-clock. Just because the lights are turned off or it gets dark doesn’t mean that your security cameras need to stop working as well.

In fact, if we study the pattern of criminal behaviour, they prefer the dark to strike so that it gets easier for them to hide and not get caught.

Many traditional CCTV cameras work great during the day or when there is adequate lighting. However, they are unable to capture clear footage, or any footage at all, in low-light or dark environments.

For that, we have infrared/night vision CCTV cameras that are designed to capture images in low-light conditions, and even in environments completely shrouded in the dark.

HOW DO INFRARED/NIGHT VISION CCTV CAMERAS WORK?

Infrared/night vision CCTV cameras use special infrared technology to enable them to see and capture clear footage in the dark. This allows for continuous monitoring and surveillance.

Infrared means “below red” and the infrared light has a lower frequency and longer wavelength than normal light. It cannot be seen with the naked eye and picks up on the heat of an object or person in its field of view.

Infrared LED lights are placed near the camera lens to help it capture images and videos, even in areas of absolute darkness. Since everything on earth puts out some level of infrared light depending on its temperature, the lens of the camera is able to pick it up and project it onto the monitor.

Infrared/night vision cameras require no additional lighting and can measure the heat emitting from objects in the area being monitored. Infrared light also has the capability to go through thick fog, dust, smoke, and even some types of materials.

A great way to determine how good an infrared/night vision CCTV camera is is by measuring its lux, which refers to the amount of light required to capture clear footage. The lower the lux of the camera, the less light it will need to record images and videos, and the better the results will be.

The best infrared/night vision cameras have a 0.0 lux in infrared mode, which means that they can capture images and videos in complete darkness without the need for any additional lights.

Another way to assess its quality and efficiency is to check how far the camera can see in the dark. This is determined by the number of LED lights built into the camera. Fewer LED lights mean that the camera has a short range, whereas more LED lights mean that it has a longer range, with some models able to see up to 150 feet in complete darkness.

INFRARED/NIGHT VISION VS DAY/NIGHT CCTV CAMERAS

Infrared cameras are also sometimes called night vision CCTV cameras for their ability to see in the dark, but neither of them should be confused with day/night CCTV cameras.

Although the three terms are often used interchangeably, infrared/night vision and day/night CCTV cameras are very different in how they work and capture images in low-light conditions.

Unlike infrared/night vision cameras, day/night CCTV cameras do not use infrared technology. Instead, they contain a sensitive imaging chip that allows the camera to capture viewable footage in the dark.

Day/night CCTV cameras are a good option for areas that have some sort of additional ambient lighting, such as a security light or a street light. They will fail to work in pitch-black environments and will fail to work if the additional lighting is switched off or damaged.

Infrared/night vision cameras, on the other hand, will produce coloured footage where light is present. In darker environments, it will switch to infrared mode and will start to record footage in black and white.

BENEFITS OF USING INFRARED/NIGHT VISION CCTV CAMERAS

Infrared/night vision CCTV cameras are extremely important if round-the-clock surveillance is what you require. They are able to capture images in low to no light and make for an effective deterrent. Here are all the benefits of using infrared/night vision CCTV cameras:

Reliable and efficient surveillance in low-light conditions

The biggest advantage of infrared/night vision cameras is that they offer reliable monitoring and surveillance in all kinds of lighting conditions, specifically in low or no-light environments. They work effectively where even day/night cameras fail and can record footage not visible to regular CCTV cameras and the human eye. This allows for constant surveillance, even during the night time or in areas with no light.

Increased security and protection

All types of CCTV cameras provide a good level of security and help keep potential criminals away. However, if they are unable to work in the dark, opportunist criminals may take advantage of the fact. This is where infrared/night vision cameras come in. Their ability to record in poor lighting conditions can be super beneficial in areas that are prone to such criminal attacks. Knowing that their activities and every single movement are monitored and recorded at all times is sure to keep them away from properties under infrared/night vision CCTV surveillance.

High-resolution footage

CCTV cameras are able to record footage in various resolutions depending on how good the camera is along with its image quality. The image resolution can range from 144p to 4K. Infrared/night vision cameras provide high-resolution images that can also be used for reliable evidence gathering in the event of an incident. The footage can be used for investigative purposes for identifying perpetrators and for legal proceedings.

Different shapes and sizes

Infrared/night vision CCTV cameras are available in various types of shapes and sizes depending on how you plan on using them and where you wish to place them. You have many options to choose from, including dome cameras which are ideal for indoor use, bullet cameras which are great for outdoor monitoring over longer distances, and PTZ cameras which allow you much more in terms of flexibility and camera control.

Remote monitoring

For added security and protection, you may opt for remote monitoring services which will allow you to access real-time as well as recorded footage from your infrared/night vision CCTV camera from anywhere in the world. You may also set up notification alerts to be sent to your phone every time the camera detects any unusual activity. This way, you can always be in the know and take immediate action.

Insurance benefits

Installing CCTV cameras on your property for monitoring purposes not only increases safety and security but also helps you save money in the form of reduced insurance premiums. Since infrared/night vision cameras provide round-the-clock surveillance, your property remains protected at all times which significantly reduces the risk of theft and other security incidents. Many insurance companies offer discounts to their clients who have taken adequate security measures to curb risks. For more details about the potential discounts and benefits, it is best to contact your insurance provider.

WHERE CAN INFRARED/NIGHT VISION CCTV CAMERAS BE USED?

Infrared/night vision CCTV cameras can be used in a variety of settings where it is important to capture footage in low-light conditions or complete darkness. Here are some of the places where infrared/night vision cameras can be used:

Outdoor surveillance:

Places such as parking lots and other outdoor facilities where lighting can be inadequate, particularly during the night, can benefit from infrared/night vision cameras and their ability to capture images in all kinds of environments. A bullet camera with a vandal-resistant casing may be a good choice for such large and open areas.

Perimeter security:

The perimeter of a facility, which includes the entry points, gates, and fences may require round-the-clock monitoring to secure it from any suspicious activity, making it very important to invest in CCTV cameras that can work in minimal lighting conditions without fail.

Retail and commercial properties:

Places such as retail stores and shopping centres are often the target of theft and burglaries, particularly after hours when the place has been shut down and the lights are off. Therefore, to make sure you are able to keep an eye on your property 24/7, you need to install cameras that work 24/7, aka infrared/night vision cameras.

Remote and dangerous locations:

Locations such as construction sites and remote factories and warehouses can seriously benefit from the use of infrared/night vision cameras since these areas are mostly unmanned after working hours and are often targeted for burglaries and vandalism.

Traffic monitoring:

Roads are often well-illuminated to make it easier for people to drive safely. However, in certain areas where the lighting is low and during the night, the authorities can make use of infrared/night vision cameras due to their ability to work all the time. They can be used to record footage of vehicles and licence plates, as well as any accidents or violations.

Home security:

Infrared/night vision cameras are just as useful for residential security as they are for commercial purposes. They can be installed in the outdoor areas, including the entry points, garden, and driveway to increase security and deter any potential criminals from targeting your home.

HOW TO CHOOSE THE BEST INFRARED/NIGHT VISION CCTV CAMERA

When choosing the best infrared/night vision CCTV camera for your security needs, you need to keep a few things in mind.

Carefully study the area that needs to be monitored and the lighting conditions of said area. If the area is very dark, you’ll have to go for models with powerful infrared capabilities so that they can capture footage in complete darkness as well.

Where you decide to place the camera will play a huge determining factor when it comes to the features. When using infrared/night vision cameras for outdoor surveillance, make sure they are able to withstand sunlight, wind, rain, and other environmental elements.

Range requirements, image quality, mounting options, budget, and integration compatibility are also some of the factors you need to consider when making the decision.

INTEGRATING INFRARED/NIGHT VISION CCTV CAMERAS WITH OTHER SECURITY SYSTEMS

Infrared/night vision CCTV cameras can be integrated with other parts of your home and business security systems to offer maximum protection against security risks.

Although CCTV cameras themselves are an incredibly effective deterrent, it is recommended to make them a bigger part of your security system as a whole.

The other types of security systems may include motion sensors, security alarms, access control systems, and security lighting.

In the case of a security event such as an intrusion, you can use the CCTV cameras to collect clear evidence and be alerted if you have enabled monitoring services and alert notifications. However, by integrating the infrared/night vision camera with other security systems, you may even stop the incident from happening in the first place.

For instance, by linking the CCTV cameras with the security lighting on your property, as soon as the camera picks up any unusual activity, it will trigger the lighting system to automatically switch on which would remove the cover of darkness and literally put the perpetrators in the spotlight.

Similarly, by linking the CCTV cameras with the security alarm system, every time the camera picks up anything suspicious, it would trigger the alarm and alert you and everyone nearby of the intrusion. A loud, blaring alarm is enough to scare anyone away from your property.

By installing infrared/night vision CCTV cameras as part of an integrated security system, you will have more control over your security and will have taken extra security measures to keep yourself and your property protected.
