CCTV Camera Systems: Everything You Need to Know

The use of CCTV camera systems has proven to be an effective tool in preventing and solving crimes all over the world. In Australia, a recent study by the Australian Institute of Criminology shows that 90 percent of police requests for CCTV footage are often granted, resulting in them solving the matters and increasing the clearance rate by almost 20 percent.

Imagine if CCTV use was normalised in all Australian streets, homes and businesses. That would result in even more clearance rates and lesser crimes.

In this article, you will learn more about CCTV cameras, how they work and their importance. You will also know how to effectively install CCTV camera systems in your home and business.

What Is CCTV?

CCTV or closed circuit television comprises one camera or a network of cameras that forms video-based surveillance that an operator can review.

When CCTV was first developed in 1927, it was as simple as a scanning-transmitting camera with a wireless transmitter and receiver. It was first used for monitoring visitors as part of government surveillance.

Since then, CCTV has evolved in terms of use. Currently, most CCTVs use digital video recorders that can record for an extended period. They also have more advanced features like email alert triggers and motion sensors.

The present use of CCTVs is limited to monitoring and surveillance, but they can also be used remotely observing areas unsuitable for humans, such as chemical processing plants.

Different Types of CCTV

Also part of the continuous enhancement of CCTV camera systems are the many different types created for specific uses. Below are some examples of the different kinds of CCTV.

  • Dome Camera

Dome cameras are widely used as indoor or outdoor CCTV cameras. Because of its dome shape, you can’t easily tell which way the camera is facing. This prevents criminals from doing their thing.

  • Bullet Camera

It is used for long-distance viewing and is ideal for outdoor use. A bullet camera also creates a high-quality image resolution.

  • Day/Night Camera

This CCTV camera is ideal for both standard and poorly lit environments. It can also record in both coloured and black and white.

  • PTZ Camera

PTZ stands for pan, tilt and zoom. As the name suggests, this camera can pan (move left or right), tilt (up and down) and zoom (closer or farther).

  • Dark Fighter Technology Camera

This CCTV camera can pick coloured high-quality images out of shallow light conditions. Its unique features include line crossing, audio and face detection.

  • ANPR/LPR Camera

Automatic number plate recognition (ANPR) and licence plate recognition (LPR) cameras detect and store registration plates on parked or slow-moving vehicles. They are effectively helpful in car parks, toll gates and hotels.

  • C-Mount Camera

C-mount cameras come with detachable lenses, which you can replace with lenses that can cover a distance beyond 40 feet.

How Does a CCTV Camera Work?

Unlike broadcast televisions which use open-circuit transmitters, CCTV uses closed circuits. Although there are various CCTV camera systems, their process is similar.

It starts with the installed cameras responsible for taking videos or a sequence of images. The files are then transmitted to the recording device via cable or wirelessly, depending on the system you are using. The recording can then be displayed on the monitor where the operator can see the footage live or review footage.

Benefits of Using CCTV Cameras

Whether your CCTV camera systems are located at home, in your business or in public areas, they give off many advantages, including:

  • Crime deterrent
  • Record keeping
  • Evidence collection
  • Activity monitoring
  • Cars and vehicle surveillance
  • Helps police investigation
  • Peace of mind

What Could I Use CCTV Footage for?

Most CCTV footage can be used to assist the police and investigators solve a crime or any matters. You can also use your home CCTV footage to collect evidence against the wrongdoings of a family member, a house helper, a nanny or even your neighbours. The same goes for your commercial CCTV whose footage can be used to see if your employees are committing acts against your company policy.

You can also use your CCTV footage in a fun and creative way. Most social media influencers take advantage of their CCTV to live stream their day or prank their unsuspected friends and family.

If you’re into photography, you can use CCTV footage to create time-lapse videos, such as sunrise and sunset or the growth and progress of your pets or kids.

Where Should CCTVs be Installed?

Public CCTVs are strategically installed in areas where crimes are more likely to occur: crowded places, dark alleys, parks, streets and others. If you plan to install your own home or commercial CCTV camera systems, place them in places you want to monitor, such as your driveway, doorstep, kids’ room, near the cashier, parking lots, service areas or in your private office where confidential documents are placed.

However, there are places where you cannot install CCTV cameras. These areas violate or invade any person’s privacy, like the restrooms, bedrooms or your neighbours’ homes.

Is It Legal to Install CCTV Camera Systems?

When used and applied correctly, CCTV camera systems are generally legal.

You must follow your state restrictions if your CCTV cameras are outdoors, like on the streets or overlooking your neighbour’s property. Alert your neighbours that a part of their properties can be seen from your CCTV system, and ensure that you have their permission before installing your CCTV.

If you do not own your home and are only renting it, you must ask for the landlord’s permission before installing CCTV cameras.

Most importantly, always give your visitors and newly hired employees a heads-up that you have CCTV camera systems around your home and business.
