What are security cameras exactly?

Security cameras are mounted video cameras used for the purpose of surveillance, as part of closed-circuit television. These devices are made to record the happenings of a specific location. Their primary purpose is to detect any criminal or harmful acts to either prevent crime or record physical evidence of criminal activity.

Due to the growing crime rates in the United States, surveillance cameras have become important tools for those who wish to protect their home or business. Security cameras can provide you with peace of mind, by allowing you to know that your home or business is safe when you’re not there.

Dean WilsonMonash University

“I think surveillance, privacy and the social impacts of surveillance are going to remain enormous questions for us as a society.”

How do security cameras work?

There are many things to consider when looking at how these devices work. Depending on the type of camera, the type of recording (permanent or only when detecting movement) and the way in which the video recording is stored will define how each device works.

In general, all security or surveillance cameras work by recording and sending the image to a recording apparatus and then to a viewing mechanism such as a television, monitor, computer (analog cameras or digital cameras with a recorder) or directly to a mobile device or tablet (IP cameras).

What types of security cameras are there?

There are two distinct types of security cameras available in the U.S. market today; analog and digital/IP. Continue reading as we go over the most relevant differences between these two types of technology.

Analog Cameras

  • Older type of surveillance cameras, it previously measured resolution in lines, new models, however, measure in pixels.
  • They come at a lower price point at the expense of image quality.
  • The image output is in analog format (alternating current signal).
  • Coaxial cabling is required for installation and operation, as well as a video storage system.
  • They require cables for each function; one cable for audio, one cable for sound and one cable for power, which can increase the cost of installation.
  • They usually use a DVR (digital video recorder).

Digital or IP cameras

  • Created with the intention of viewing the images over the Internet via a local or wireless network.
  • They can operate wirelessly or via coaxial cable/twisted pair cable (UTP).
  • They offer more possibilities when viewing, such as zooming in, facial recognition and motion detection.
  • They usually store footage in an SD memory card or a cloud service. An NVR (Network Video Recorder) can also be used.
  • They provide much higher image resolution as they usually offer high definition (HD) or 4K video recording.
  • Easy installation, wireless operation and when using cables, usually only one cable for power, video, audio, and control is required.

Security cameras can also be classified by their design or shape as explained in the following table:

Type Features
Dome The most popular model to be used in homes or small businesses. They have a “dome” shape with a lens in the center. Those with night vision will have infrared LEDs built around the lens.
Bullet They are elongated in design and are also popular for the home or small businesses. They are suitable for outdoor use. Their lens is located in the center and they offer infrared LEDs to monitor during the night.
Box They are also slightly elongated, but rectangular in shape since the box and lens are separated. They are usually used by larger businesses or government organizations. In some cases, you must select the lens it uses.
PTZ The acronym stands for “Pan” (rotate horizontally), “Tilt” (rotate vertically) and “Zoom” (look closer at the subject). They are controlled remotely by a control center or device applications. They are cameras intended for professional use such as in department stores, prisons, parks, and airports.

What video storage and recording methods do surveillance cameras have?

There are 3 different methods of video storage used by security cameras today. As mentioned before, this will also depend on whether the camera is analog or digital, which directly affects the available recording capabilities.

Storage method Features
Digital Video Recorder (DVR) Used to record images from an analog security system.
Requires coaxial cable to connect the camera to the video storage unit and from there, send the images to a monitoring location.
Converts an analog signal to a digital signal.
In some cases, it is possible to connect a DVR system to the Internet to monitor the camera remotely.
Network Video Recorder (NVR) Connects to the digital or IP camera via a network or twisted-pair cable.
Recommended method if the camera does not have an SD memory card slot.
Signal conversion is not required.
Connected to the Internet to allow remote monitoring.
SD Memory Card Used only by digital security cameras.
Typical security cameras support 64GB to 120GB SD cards.
The recording remains inside the camera which requires the memory to be cleared once full.
Very practical as no additional wiring or video storage system is required.
It is possible to store the recording in a cloud service, either private or hosted cloud such as AWS (Amazon Web Services).

Buyer’s Guide

You may have thought that the function of a security camera is simply to detect movement, record and send some kind of alert. Technological advances have changed the way these devices perform, allowing for functions that go much further than this. To make the best purchase, review the following criteria before making your final purchase:

Alerts and Applications

It will be crucial that the security camera you choose can send you alerts to your phone or other devices when it detects abnormal behaviors of movements. This will allow you to check-in only when something is actually happening, instead of having to perform constant surveillance. Some security cameras include an application to monitor and control the camera from your mobile phone, tablet or computer.

The advantage of a specialized application is that you can watch a live feed from anywhere as long as you have an Internet connection. Moreover, certain applications allow you to perform real-time actions like stop or activate recording or changing the direction of the camera lens to have a better view of what is happening in the area.

Facial Recognition

On the U.S. market today, you can find surveillance cameras that have facial recognition software. Through this advanced software, the security camera is able to analyze and compare video segments to identify the physical or facial features of a person, and with this, their identity.

The facial recognition software allows alarms to be disabled if the security camera recognizes that the person is a known or approved individual for the location, which decreases unnecessary alerts. On the other hand, if the system is unable to identify the person, an alert will be triggered immediately.


Did you know that the security camera was designed and installed by the German engineer Walter Bruch. In 1992, 20 years after Walter Bruch developed the first camera, a security camera made its appearance in Olean, New York, USA. The city installed security cameras in a business district to help fight and deter crime.

Resolution and Night Vision

With the advances in technology in terms of image resolution and quality of the recording, you can now find cameras that record in full HD or 4k resolution. We should not that the better the resolution, the easier it will be to recognize intruders and see exactly what’s happening in the recording.

Keep in mind that the video resolution may be lowered when files are uploaded to the cloud. This step usually reduces video quality to 720 pixels in order to save space and decrease file transfer times.

Since most crime happens at night, we suggest whatever camera you choose has night vision. Some models will automatically switch to this mode when they are unable to detect enough light to record, while with other models you can pre-set the night vision mode to start with a timer.

Viewing, Tilt and Rotation Angles

Panning, tilting and zooming (PTZ) capabilities will determine how many different angles you can shoot and how accurately you can record the happening of a specific location. The level of PTZ will vary from model to model as some cameras have a much wider viewing angles than others, — make sure to review the viewing range of each camera.

If your camera can rotate and zoom, you can cover a larger area by directing the camera specifically in the direction you want to see. The surveillance cameras that work with a tailored application are much better since they allow you to control these movements in real-time and remotely from your personal device.

We would suggest that you opt for a model with a viewing angle of at least 130°, with the ability to rotate up to 80°. With these viewing abilities and range of movement, you will be able to have a viewing scope of almost 360°, which will allow you to have total control over the location that is under surveillance.

Storage Method

One advantage of local storage, whether on a memory card or separate storage device, is that the resolution of the recordings will not be altered. However, the main disadvantage of this type of storage is that if someone steals the actual device, you won’t be able to retrieve the recording.


Overall, there are about 25 million CCTV cameras set up across the globe.

Motion Sensors

Another feature that is considered of the utmost importance when buying a security camera is that it has motion sensor technology. With motion sensors, if someone has broken into your home or business, you can be notified and tune into the footage immediately. Devices of more refined technology will offer features that reduce the number of false alarms.

For example, some of the more sophisticated security camera models will be able to differentiate between people, animals or cars before triggering the motion sensor. The level of sophistication of the motion sensor will depend on the price of the device, as well as the sensitivity of the sensor itself.

Two-Way Audio

Last but not least is an additional feature that only the most professional security cameras have. Although the main function of surveillance cameras is to record images, it is certainly better if you can also record audio. A security camera with audio capabilities will enable you to see and hear absolutely everything that’s going on.

In addition, security cameras that have the ability to record sounds may also have the ability to emit sounds through a small built-in speaker. This can be useful for communicating with the room to deter or intimidate an intruder.


By purchasing a security camera you will be investing in the security of your home, business, your children’s wellbeing or your pet’s safety when you are not present. Security cameras have become much more affordable in recent decades, which means they are no longer meant to be used exclusively by big companies or those with a lot of money.

If buying a security camera is within your means, we recommend that you invest in this tech to give you peace of mind as well as potentially saving you a lot of money and grief from unwanted intrusions and illicit activities in your home or business. As a business owner, you will not only be able to monitor your business premises, but your employees and customers will feel more secure and protected.
