No matter your line of work, installing a CCTV system in your business is one of the most effective ways of preventing crime and protecting your workers. Numerous studies have shown that intruders are deterred by the presence of a camera. CCTV also provides invaluable evidence – not just after a crime but also in the event of an accident where you may have to make an insurance claim. CCTV may even reduce your insurance premiums!
This article provides an overview of what to look for when buying a CCTV security system.
Key Elements of a CCTV Security System
A CCTV security system typically consists of the following:
- Cameras
- Recording equipment
- Video monitors
- Power supply
A CCTV security system provides visual identification of customers, employees, and vendors; it can detect and deter intruders, and it can monitor activity within the premises for added security.
Cameras
The camera is the most important component of a CCTV security system. The types of cameras you should choose depends on the requirements of the particular security system. There are multiple different types of cameras available:
- Bullet cameras are the most common type of CCTV camera and are the most versatile. These cameras usually come with a wide angle of view and offer excellent video performance in a range of weather conditions.
- Dome cameras are the most popular type of cameras used in public places. They are generally good for indoor and outdoor conditions. They are available in both varifocal and fixed models, allowing users to customise the resolution and coverage area depending on their needs.
- IP cameras are becoming increasingly popular in the commercial CCTV security system market due to their flexibility and high video quality. These cameras can be used to monitor large areas with multiple cameras linked together, or they can be used to provide a single HD video camera with multiple smaller cameras tied together.
- Day/night cameras are ideal for standard and poorly lit environments, as they provide clear images in both daytime and low-light conditions. They can record in colour and black and white.
- PTZ Cameras: PTZ stands for pan, tilt and zoom; as the name suggests, you can move the camera around and zoom in and out. PTZ cameras allow you to freely watch a location in any way you want.
Recording Equipment
The recording equipment used in a CCTV security system is the foundation of the entire system. It is responsible for storing all data captured by the cameras and recording it in a digital format. There are two main types of recording equipment—NVR (Network Video Recorder) and DVR (Digital Video Recorder).
An NVR is a network-based recording device that is capable of recording high-definition video from multiple IP cameras and storing it in a digital format. The main advantage of an NVR is that it is much more efficient and has better performance than a DVR, but it is also more expensive.
A DVR is essentially a computerised video recorder that captures and stores standard-definition videos. DVRs are typically cheaper than NVRs and are easier to install, making them popular in small to medium-sized businesses.
Footage can also be saved to secure cloud storage and/or offline hard drives for peace of mind.
Video Monitors
Video monitors are used to display live footage from CCTV cameras in real-time. This can be used to identify people or objects that may be a security risk. Monitors can also be used to review recorded footage to investigate crimes or any other suspicious behaviour.
The type of monitor chosen should match the camera’s resolution and video quality, as this will make the most of the footage captured by the camera. The size of the monitor should also be considered – the larger the monitor, the more likely it is that a person or object will be identified in the footage. Most CCTV security systems will include a monitor as part of the recording equipment.
Many CCTV systems also allow you to access a live stream or recorded footage from anywhere via a smartphone.
Power Supply
A power supply is an essential component of a CCTV security system, as it is responsible for providing the necessary electricity to the cameras and recording equipment. The power supply should be able to supply enough power to keep the system functioning without interruption. Many CCTV systems also provide battery backups so that they will continue to function in the event of a power outage.
