Also referred to as an infrared security camera, this type of security camera was explicitly developed to utilize infrared technology for low light and nighttime surveillance. Whereas several years ago, it might’ve been unique to a specific type of camera, it is now widely implemented as a measure and can be found commonly for affordable prices. A1 Security Cameras does not necessarily include a category for such devices here on our site because it is such a common feature.

What kind of camera can see infrared?

When considering how to enhance your security camera system during low light hours, chances are you will be directed towards an infrared CCTV camera. Also referred to as an infrared security camera, this type of security camera was explicitly developed to utilize infrared technology for low light and nighttime surveillance. Whereas several years ago, it might’ve been unique to a specific type of camera, it is now widely implemented as a measure and can be found commonly for affordable prices. A1 Security Cameras does not necessarily include a category for such devices here on our site because it is such a common feature.

In this article, A1 Security Cameras will provide you with a basic understanding of infrared security cameras and how they work. Specifically, we will define what they are, their capabilities, devices that can enhance them, and provide greater detail into some of the questions we have received about this specific security camera.

What are infrared cameras?

CCTV infrared or infrared security cameras are devices used for surveillance in low light or nighttime conditions. Also known as night vision cameras, these devices improve a security camera system with enhanced performance when implemented in key positions or throughout. Whereas standard security cameras released today feature some capability in this regard, some specialization is needed after a certain threshold.

Infrared security cameras work similarly to their regular counterparts, using infrared sensors internally and infrared lights generally located around the lens. These lights then activate during occasions of low or no light, allowing the camera sensor to pick up imagery and still produce video footage. Unless otherwise specified, recorded data recorded by CCTV infrared will only be in black and white. Sometimes such devices will feature more labels based on infrared technology, but such products have a different distinction.

Are infrared cameras good?

Whereas standard surveillance will have trouble providing you with acceptable video quality during low light and nighttime conditions, infrared security cameras will not. As mentioned, these devices effectively view through low visibility brought by a definite lack of light and allow a given security camera system owner to enjoy clear video footage through their recorder regardless of whether it's captured during the day or night.

A1 Security Cameras encourages our customers to consider infrared security cameras due to their capability at night, especially for outdoor cameras. Again, each modern camera meant for surveillance with a traditional design will have some measure of infrared but are not specialized past the point where visibility just starts getting difficult for the human eye. Those considering infrared security cameras might want to have a slight understanding of IR range.

What is an IR range in cameras?

If your only reference for surveillance is fiction, you might believe that infrared security cameras can see anything, even in complete darkness. However, in reality, cameras are restricted to a specific range depending on what is specified in their spec sheet. This particular detail is referred to as an IR range and defines how far the infrared light illuminates the environment within its given view. This option is represented as “Night Vision Range” when shopping through the A1 Security Camera site. For example, it can be found in the “refine by” feature in applicable categories like IP cameras.

Best brands for infrared cameras

Best brands for infrared cameras

As can be seen, A1 Security Cameras has a wide selection of infrared security cameras throughout each of the categories we present. Likewise, each brand features unique advancements to its products that make implementing them into your surveillance worthwhile. While each brand on our site features a wide range of CCTV infrared, here are the most noteworthy.

AXIS: Known for its high-quality cameras, AXIS has innovated several sophisticated features into its infrared security cameras. One such example is the Axis Optimized IR technology, which improves low-light recording performance by providing better focus in a given view.

LTS Security: Recognized as one of the most affordable and reliable options for surveillance, it is no surprise that LTS also focuses on improving infrared security cameras. An excellent example of this is the LTS Matrix IR 2.0, which applies a more compact yet enhanced infrared technology to both HD analog and IP cameras under the brand name.

Vivotek: A great choice when considering surveillance, Vivotek infrared security cameras provide an expanded capacity to surveil low light and nighttime environments. One such technology that should be considered when looking at night vision capability is Vivotek’s Supreme Night Visibility. This option provides detail in close, mid, and far infrared viewing while enhancing adaption to varying light sources.

What can inhibit infrared?

What inhibits infrared security cameras will generally be the same as standard surveillance. Obviously, usual physical barriers like trucks and weather play factors. For less adaptive CCTV infrared technology, changes in light can temporarily reduce video footage quality. At the same time, another factor tends to be the need for a reliable stream of energy that matches the device's requirements.

With the growth of popularity in wireless technology also comes the rise of tools used by malicious parties that disable WiFi cameras. For example, a given wireless infrared security camera can be disabled by a jammer. Such a device blocks wireless signals from reaching the device by overloading or matching the signal. The surefire way to avoid this threat is to use a hardwired surveillance system.

What are IR illuminators?

What are IR illuminators?

When your infrared security camera provides less than satisfactory performance in low-light environments, infrared illuminators are what you look to purchase. The concept and purpose behind these devices are straightforward, simply being technology that emits infrared light. Depending on the design, some can be similar to a spotlight, while most are more comparable to regular lights that illuminate an area for the specific cameras. Unlike regular lights, IR illuminators emit a stream of infrared that the human eye cannot detect. As such, it will not bother people or most animals when used.

Where do you put an IR illuminator?

An illuminator designed for infrared security cameras should have a practical vantage point over an environment where cameras are meant to monitor. Like normal light and camera placement, the illuminator should be placed at least a foot above a camera for the best possible outcome. While they can be placed next to cameras, they should never be positioned below. Furthermore, an appropriate vantage point for infrared security cameras and illuminators should be around one dozen feet off the ground if possible. At a minimum, they should be out of reach for a person without additional equipment.

Is infrared the same as night vision?

Most of the time, yes, night vision is another way to say and reference infrared capable devices. Whereas there might have been a distinct lack of detail through older infrared security cameras, such devices are now capable of picking up more delicate features and can adapt to varying sources of light far more effectively.

It should be noted that there is a general misconception about night vision in that it may refer to any technology that provides improved vision in low light conditions. Unfortunately, the label may sometimes apply to thermal, light-sensitive, and infrared devices. The confusion arises from the ability each grant during low light conditions and has primarily originated from use in pop culture and when referencing equipment designated for military use. However, night vision is defined by A1 Security Cameras as technology based in infrared.

Do all infrared cameras glow red?

No, infrared cameras should not emit a light detected by the human eye and only be noticed by certain animals like frogs, foxes, and certain insects. There might be indicator lights located on the cameras that indicate recording or general functionality, but that makes no difference on performance nor is meant to signify anything to do with the infrared.

Can infrared cameras see through walls?

No, infrared security cameras cannot see through walls or solid surfaces. Instead, these devices function almost entirely like standard surveillance, being limited by the environment it monitors. As mentioned, there is a general misconception between infrared and thermal devices providing the same capability. In reality, neither can penetrate solid surfaces unless superheated for thermal whereas infrared will only detect movement it can see.

Why buy an infrared camera?

Infrared security cameras provide your security camera system with the ability to view a given environment in the dark. Whether you are a homeowner or business manager, CCTV infrared should be considered simply for security alone due to many crimes often happening at night. Fortunately for the average consumer, attaining such security cameras has become entirely affordable, especially through A1 Security Cameras. Residents and business owners in Dallas Fort Worth can even have these cameras installed by our installation team.
