What are Infrared Security Cameras and How Do They Work?

With quality security systems, homeowners or business owners have a peace of mind as they are guaranteed of safety against potential intruders. Infrared security cameras are the finest, providing users with quality night and day surveillance. Initially, most people utilized the traditional video security systems. These out-of-date surveillance cameras have weaknesses, which make them all but inefficient nowadays. One of these drawbacks entails their dependence on visible light to capture media. This has proved troublesome since the majority of invasions take place at night when lighting is dim or unavailable. Thankfully, the infrared security cameras are equipped with state-of-the-art features; hence they can capture images even in dark conditions. This overview describes what an infrared camera is and how it functions.

What is an infrared security camera?

Put simply; an IR camera is a device that generates images from infrared radiation. Also called a thermographic camera, this gadget utilizes wavelengths longer than the visible light to form images even in complete darkness. There are two main types of infrared cameras namely: cooled infrared detectors and uncooled infrared detectors.

Typically, infrared cameras work by determining the amount of radiation that a particular object emits depending on its temperature. A hot object emits more radiation, resulting in a more intense image color. The primary infrared cameras display images based on the color spectrum. The hottest section of the image reflects white while the less warm sections reflect red and yellow. The cool parts, which are the least intense, reflect in blue color.

A cooled infrared detector employs a cooling technique called the Joule-Thomson effect to create the image. It involves cooling the device to facilitate detection of the radiation emitted by an object; thus, producing clearer images than the traditional infrared cameras. Conversely, the uncooled infrared detector requires no cooling. Instead, it works at the ambient temperature. It senses the heat emitted by an object then converts it to an image using voltage changes.

How infrared camera works

In general, an infrared camera works by detecting heat energy emitted by an object. The heat is converted into an electronic signal, which is then processed to create a thermal image and enable temperature calculations. The distinctive feature of an infrared camera is that it can quantify the heat detected from an object. This way, you can monitor thermal performance and diagnose any heat-related problems that crop up.

Presently, infrared innovations provide users with more cost-effective thermal assessment solutions than before. For instance, thermal cameras now utilize Picture-in-Picture (PIP) technology, which enables one to overlay a thermal picture over a regular digital image. Based on the type of infrared camera, you can resize the thermal image or have it fixed in the middle of your display image. Other modern infrared cameras even permit the fusion of infrared and digital images.

Infrared cameras confer many benefits to users; one of them being the capacity to conserve energy. Surveillance videos that are equipped with IR capabilities typically utilize light emitting diodes (LEDs) to generate infrared illumination. LEDs are known to use 80 percent less energy compared to incandescent lighting, and still, produce an equivalent intensity of light. What’s more, most infrared cameras contain photocells, which turn the IR light on and off; thus, providing illumination only when required.

Another admirable feature of an infrared camera is its enhanced light penetration capability. Infrared light can penetrate a cloudy atmosphere better than visible light. If you live in a region that experiences high levels of humidity or pollution, using infrared security cameras is the ideal option.

How to choose an infrared security camera

IR thermography is now a renowned technology. It has encouraged the majority of infrared camera manufacturers to produce an array of products. You can get quality infrared cameras from Annkestore. When planning to buy an IR camera, you should base your decision on the core parameters such as temperature range, spatial resolution, detector size and budget.

Temperature Range

The temperature range is determined based on the intended application. Making a mistake in this phase can leave you with a virtually ineffective piece of equipment. Presently, manufacturers make cameras that are customized for building security purposes. As such, this type of IR camera should not be used in other applications such as electrical inspection. Before purchasing an infrared security camera, you should first determine the application and then check the temperature range.

Detector size

The detector size has a significant impact on picture quality and camera price. An infrared camera is similar to a digital camera in that, a large number of pixels results in a clearer image. IR detector sizes range from 160 × 120 to 640 × 480 (307,200 pixels). When buying an infrared camera, pick one that has a high number of pixels.


You need not overlook how the IR camera stores images. Frequent use of the IR camera generates tons of thermal images; hence, the need for neat storage, filing and retrieval of the media captured. If you store the data on an SD card within the IR camera, ensure that the card has enough storage space.

Spatial Resolution

Put simply, spatial resolution refers to the quality of the images and is expressed as an angle. It defines the tiniest object that an infrared camera can resolve at a given distance. With a small IFOV (Instantaneous Filed of View) angle, one can view objects at a distance with much ease. Spatial resolution is usually determined using the infrared camera detector and lens.


You should tailor your budget based on your requirements. Many individuals assume that all infrared security cameras are the same. If you plan to use the camera frequently, invest your money in a quality infrared camera. It should have a minimum of 320 × 240-pixel detector; compatibility with accessory lenses and produces clear and accurate thermal images.

Safety and security remain the top considerations for most homeowners and business-owners. With infrared security cameras, you are guaranteed of ultimate protection. These devices can also be optimized for the intended applications such as indoor and outdoor placement options, weatherproof and extended views.

PTZ CCTV Security Cameras and Their Benefits

Whether you want to monitor multiple directions in an airport terminal or a massive parking lot, covering vast areas has long been a challenge for security surveillance systems. The traditional analog cameras have other limitations with regards to resolution, depth and area coverage. However, modern IP cameras have mitigated their predecessors’ shortcomings by covering broad areas in high resolution.

These cameras fall into two main categories: fixed and the pan-tilt-zoom types. In the case of fixed, the camera is mounted in a stationary position. It means that the device only captures one scene unless it is physically located. In contrast, pan-tilt-zoom cameras are designed for remote directional and zooming capabilities.

Panning, Tilting, and Zooming Features Explained


It refers to the horizontal movement of a surveillance camera from a fixed position. Put simply, the camera posses the ability to scan an object horizontally or “back and forth.” Panning offers the benefit of scanning both mobile objects and vast field of view areas such as industrial firms.


It is the vertical movement of a surveillance camera, which is placed in a stationary point. This feature is beneficial in that it allows cameras to scan vertical fields of view such as rooftops and other outdoor structures.


The zoom-in function helps magnify subjects within a particular field of view. For example, a vehicle that is parked hundreds of feet away is big enough to see; however, it is hard to determine the license plates. The PTZ camera is fitted with lenses, capable of enlarging the size of the license plate; hence, making it easy to read even the license numbers and letters.

How PTZ Cameras Work

PTZ CCTV security cameras come equipped with particular mechanical elements that facilitate movement of both the camera and lens. These surveillance cameras allow automatic rotation whenever motion is detected. The range of movement differs from one model to another. Some cameras can make a 360-degree pan, meaning the device turns in a complete circle to prevent blind spots. In contrast, the 180-degree tilt enables the camera to view straight ahead, below and above its position. While a smaller range of movement functions aptly, it is prudent to get the full movement. This way, your camera will have more flexibility.

The Benefits of PTZ Surveillance Cameras

Large Field of View

Depending on where the camera is mounted, it can cover a whole 360-degree area. The majority of models allow users to set particular surveillance modes at pre-determined durations. Typically, the pan and tilt settings can be pre-programmed, making it easy to monitor large areas that would otherwise necessitate the use of multiple cameras. The use of a single camera means that you can minimize costs while maximizing your level of security.

Built-in Motion Tracking

Virtually all pan-tilt-zoom cameras are equipped with a built-in tracking device. This feature detects motion or tracks a subject; automatically panning, tilting or zooming to trail the person or object as it moves. It is beneficial in that it provides proof in the event of theft or vandalism. When purchasing a PTZ camera, ensure that it has this full motion tracking capability.

Night Vision

The night vision capability comes in handy when you want to monitor areas with poor lighting conditions. With surveillance cameras, the amount of lighting present is paramount in recording high-resolution images. The model of PTZ Speed Dome camera, which is developed recently, can capture media in total darkness. It is achieved with the aid of tiny LEDs that give out infrared light and a unique IR filter that comes with the camera lens. Infrared lighting cannot be seen by the human eye, but through the IR filter, the camera records images from any lighting conditions.


Another merit of using PTZ CCTV security cameras is that they are designed to withstand the harshest elements. It means that they can be utilized for outdoor applications regardless of the climatic condition; be it the wind, rain or snow.

Powerful Zoom

Most PTZ cameras in the market have detection abilities of 100 feet on the low side and up to 1,000 feet on the pricier models. Capacity to zoom in on a subject ranges from 12X to 36X for the sophisticated PTZ Speed Domes.

Easy Installation

As earlier mentioned, a single PTZ camera can cover a wider range of property than multiple fixed cameras. Therefore, instead of purchasing an array of surveillance cameras to monitor your garage, invest in one or two PTZ cameras. Buying PTZ cameras will not only save you on the initial cost but also the time spent on setting up the system. These PTZ cameras are available on Annkestore.

High Definition Options

Presently, PTZ cameras are available in IP versions, which deliver quality resolutions of between 720i to 1080P. Alternately, you can select the PTZ cameras that come equipped with HD-SDI technology, which offers high definition video in full 1080P resolution.

Vandal-proof and Aesthetic Design

Most of the PTZ surveillance cameras are made with a dome-shaped design. These cameras are made of a vandal-resistant plastic material; thus, they are prone to smashing and breakage. Moreover, they are often positioned high above the ground where people cannot reach them, which makes them resistant to tampering.

Multiple Alarm Inputs

The majority of PTZ CCTV security cameras comprise of four alarm inputs. Therefore, you can connect other vital devices including motion sensors, door contacts or glass-break sensors. If any action takes place in either of these hot spots, the PTZ camera is programmed to cease recording other scenes and zero in on this section to capture what is going on.

ptz cameras and benefits

The pan, tilt and zoom cameras are useful for an array of security purposes. Usually, these units are controlled mechanically to give users a vast range of views and perspectives from the same camera. PTZ cameras are mainly used in larger spaces, where detailed and multiple imaging is required. They offer numerous benefits including built-in motion tracking, powerful zoom-in feature, and a vandal-proof design. The fact that one single PTZ camera covers a wide area also eliminates the need of installing multiple cameras; hence, save on cost and time.
