The major advancement that some surveillance camera manufacturers offer with increasingly affordable product lines is artificial intelligence. This technology, however, is difficult to implement, and only a few major international manufacturers, such as AVTech, Hikvision and Dahua, are capable of providing truly accomplished and functional solutions.

Cameras with artificial intelligence enable real-time detection and alerts on humans, vehicles, and fire detection, among other things. They also enable strategic analysis, such as people counting cameras.

Color Night Vision Camera

Color Night Vision Camera

Previously, surveillance cameras could only see in black and white at night; now, they can also see in color. Seeing in color at night is especially useful for obtaining critical details such as the color of a car, the color of a person's jacket, and so on... This information can be used much more effectively by law enforcement and security services to conduct quick and accurate identification.

There are numerous models of surveillance cameras that include AI, color night vision, or both.

What is the most effective surveillance camera in 2022?

This is a question that many people ask themselves incorrectly. There is no best surveillance camera, but depending on your needs, you can find the best camera. There are several criteria to consider when selecting the right surveillance camera: what should I protect myself from? What is my CCTV budget? What places do I want to safeguard, a home, a business, an office, a gym, and so on?

Let's look at technology.

Technologies have advanced significantly, and it is now possible to outfit yourself with a highly reliable and high-performance video surveillance system, with products to suit all budgets.

Artificial intelligence surveillance camera

Many surveillance cameras include artificial intelligence, and its utility is well established. The main benefits of a surveillance camera are accurate detection and real-time alerting. It allows you to be notified when something happens in your camera's visual field. It is critical to initiate an action in order to prevent a burglary, theft, ransacking, aggression, and so on.

In reference to more traditional detection technologies. Until recently, cameras had relatively "basic" detection systems that relied primarily on pixel changes at the camera sensor. This allowed the camera to detect everything that passed through its visual field. However, it resulted in a large number of false positives. A false positive is a detection that is unwarranted. A false positive was caused by, for example, leaves blowing in the wind, an animal passing in front of the camera, or a sudden change in brightness following the passage of a cloud in front of the sun. As a result, the detections were unreliable and difficult to use.

Then came more advanced detections, such as those based on the crossing of a virtual line or intrusion detection. When a user draws a line on the camera image, an alert is triggered when it is crossed. Similarly, it can draw an area that triggers an alert when an intrusion in the latter is detected by the camera. These technologies have significantly reduced false positives, but they have not been limited sufficiently for optimal day-to-day use.

Artificial intelligence is the great revolution that, for the first time, makes security cameras truly effective on a daily basis by only sending justified alerts to your smartphone or tablet.

Depending on the manufacturer, artificial intelligence integrated into surveillance cameras goes by a variety of names. This technology is known as AcuSense at Hikvision. Hikvision cameras are currently using AcuSense technology in version 2.0. It allows for a false positive rate of less than 2%.


What is Hikvision's AcuSense technology and how does it work?

The camera's algorithm allows the artificial intelligence to focus solely on humans, vehicles, or both. As a result, you will receive instant, dependable, and verifiable detections. AcuSense technology enables home, business, or business owners to respond to security incidents in real time. Security is then taken to the next level, allowing for quicker responses before losses or damage occurs.

Surveillance camera with color vision at night

Until now, cameras in the dark could only provide a black-and-white image using infrared lighting. In the context of 24-hour security, this black and white vision provides a lot of very interesting information. However, some information may be lost when viewing in black and white. Color vision at night transforms safety. This enables us to know, for example, that the car that caused an accident was red, or that the intruder was dressed in yellow pants and a blue jacket. Color, when combined with real-time alerts, provides a broader range of essential information and increases responsiveness to challenge an individual or deal with a threat.

Hikvision's ColorVu technology is the brand name for this technology. ColorVu technology serves as the system's eyes. When combined with the AcuSense AI technology, which serves as the brain, you get results in terms of detection and alert precision that have never been seen before.

To implement this technology, manufacturers have had to rely on the development of entirely new sensors that incorporate a lens with a large F1.0 aperture capable of capturing significantly more light in order to obtain brighter images with more balanced exposure. The ColorVu camera can film in color at all times due to its high sensitivity in low-light environments.

To help it maintain color vision at night, the ColorVu security camera can activate fill lighting with warm visible (non-infrared) light. A ColorVu camera has a sensitivity of 0.0005 Lux. A full moon night, on the other hand, illuminates at 0.5 Lux.


How do I pick the best surveillance camera for my needs?

After deciding on a technology such as a traditional camera, AcuSense, or ColorVu, the location of the camera must be determined, whether it will be installed indoors or outdoors.

Indoor surveillance camera 2022

To equip you with an interior security camera, it is often recommended to go with dome cameras, primarily for aesthetic and discretion reasons. These cameras should ideally be installed upside down under the ceiling. Otherwise, a less aesthetically pleasing support will be required. In the case of vertical installation against a wall, a mini tube camera is preferable. There are more discrete mini dome cameras available, such as the DS-2CD2546G2-IS and DS-2CD2543G2-IS models. Both cameras feature AcuSense technology as well as a built-in microphone.

There are also cube cameras, such as the DS-2CD2443G0-IW, that can be placed vertically against a wall, under a ceiling, or even on a piece of furniture due to their foot mounted on a ball joint.


The EZVIZ brand provides a wide range of WiFi indoor surveillance cameras with advanced features like automatic target tracking.


Outdoor surveillance camera 2022

The selection of outdoor cameras is more critical. Let's stick with smart cameras that use AcuSense or ColorVu technology, which are the new 2022 trend.


Certain models will be more appropriate depending on the type of property to be monitored (business, office, home, etc.). When you are not a specialist, it is best to seek advice from video surveillance experts.

Outdoor cameras are classified into three types.


  • -          Surveillance camera with fixed focus


  • -          Surveillance camera with varifocal lenses


  • -          PTZ security camera


The type of camera and lens must then be selected.

What is a Fixed Focus Camera?

Fixed Focus Camera

Fixed-focus cameras have a field of view that ranges from 100° to 180°. Pop-up cameras are what they're called. That is, they have a wide field of vision, allowing you to see the entirety of a scene without a high level of detail if the scene being filmed is far away from the camera. These are the most popular cameras because they meet a wide range of requirements.

What is a Varifocal lens camera?

Varifocal lens camera

Optical zoom is available on varifocal cameras. This allows you to precisely customize the area to be filmed by zooming in and out.

This can be very useful, for example, if you want to film the entrance to a parking lot in order to clearly identify a license plate. Varifocal cameras can be used in conjunction with fixed lens cameras. To return to the car park example, it will be interesting to pair the varifocal camera with a camera with a wide field of view in order to see everything that is going on in the parking lot. The fixed-focus camera will show that at 2:15 p.m., the blue car collided with the red car and exited the parking lot. However, it will not have enough resolution to see the license plate. The images from the varifocal camera will then suffice to identify the vehicle plate at 2:15 p.m.

What is a PTZ Camera?

PTZ Camera

A PTZ camera, also known as a rotating camera, can rotate from right to left, up and down, and has a powerful optical zoom that allows it to see fine details at a great distance. PTZ cameras, for the most part, have advanced features like auto-tracking or smart tracking. This feature enables them to track a target without the need for human intervention. They can also be programmed to go around and scan the area to be monitored on a regular basis.

To complete the selection of its camera, it is necessary to consider night vision.

What is the best night vision for a surveillance camera?

The surveillance cameras can see daylight all the way to the horizon. They, like our eyes, can see for miles if there are no obstacles. On the other hand, the further the scene to be filmed is from the camera, the less precise and usable the details will be.

The cameras' vision is much more limited at night. This vision is influenced by the power of the camera's LEDs, whether it is using ColorVu technology or black and white vision (infrared).

Night vision ranges from 10 to 30 meters for indoor cameras. Night vision ranges from 20 to 500 meters for the most powerful outdoor cameras. The most powerful non-rotating cameras have a maximum night vision range of 80 meters. Beyond that, if you want to see the night at 100 meters, 200 meters, and so on, you'll need to upgrade to a PTZ camera, which is the only type of camera capable of providing night vision over such distances.

Finally, you will need to select the camera's resolution. The majority of cameras have resolutions ranging from 2MP (1080p) to 8MP (4K).

Which resolution should I use for my security camera?

The resolution is determined by your requirements as well as the distance between the camera and the subject to be filmed. A 2MP (full HD) camera will suffice if you simply want to see what's going on in your garden but don't need to identify an individual (to clear up any doubts). indicated. If you need a camera that can recognize a person, license plate, or other object, you'll need to go with a higher resolution.

The most common resolutions for surveillance cameras are 2MP (full HD 1080p), 4 or 5MP, and 8MP (4K). The DORI principle can assist you in determining the best camera for your needs.

What exactly is the DORI principle?

DORI is a critical principle in video surveillance for selecting the right camera model. The DORI distance (Detect, Observe, Recognize, Identify) indicates the camera's ability to distinguish between people and objects in its field of view. It is calculated using the camera sensor specifications and the criteria specified in EN 62676-4: 2015.


Detection (25 pixels per meter): The distance at which a person in the camera image can be detected. This will only detect a human form but will not provide any specifics.

Observation (63 pixels per meter): The Observation level provides distinguishing details about an individual, such as distinctive clothing, while also allowing activity in the surrounding area to be seen.


Recognize (125 pixels per meter): The level of recognition allows for a high degree of certainty in determining whether an individual in relation to his overall characteristics. This allows for recognition but not identification.


Identify (250 pixels per meter): The identify level provides a detailed description of a person's characteristics such as clothing, facial features, facial expressions, and other personal characteristics.


The DORI system is inextricably linked to the camera's resolution. It is also calculated for images taken during the day. The distance is reduced by 30% to 40% at night in black and white. This heightens interest in the ColorVu technology, which allows for the preservation of a color image at night.
