The composition of a video surveillance system - what does it include?
A video surveillance system includes multiple devices that allow an organization to broadcast and receive a video stream. Their quality of being movable enables them to install anywhere, in homes, offices, apartments, even places, business premises etc. Thanks to such devices, it is easy to monitor and control events happening at the premises from anywhere in the world using cloud services.
A video intrusion detection and prevention system consists of many components that have different features and specs, which we will discuss below:
Types of video surveillance complexes
According to their configuration, the camera security system can be easily divided into two categories, namely digital and analogue. Analogue devices work on a fairly simple principle: each frame is recorded using a video recorder. In contrast, digital camera surveillance equipment is more popular due to its many user-friendly features and an option to integrate it with other security devices.
Digital video surveillance systems can easily:
Transfer data from different video cameras, from warehouses and factories to information display devices;
Record and analyze data;
IoT and sensor based cameras can also automatically make decisions to ensure the safety of the facility.
You can easily find analog cameras in private houses and residential societies. Digital cameras are a bit expensive and are used in large organizations with hundreds of employees and many valuable objects.
Components for video surveillance systems:
A video intrusion detection and prevention system can have multiple components and features. Many factors influence its configuration:
Functionalities of the premises where the video surveillance system is set up.
Tasks that need to be resolved.
Financial capabilities of the organization.
The simplest video surveillance system comprises a video camera, a monitor and intrusion detection system software that helps them interact with each other. According to many, these devices are not capable of organizing high-quality monitoring of valuable objects. However, it's a misconception. While using such a video security system, a person from the security team must always be on duty to monitor the movements. Moreover, such a system can only provide partial viewing of the object. For eliminating this shortcoming and expanding the features of the security system, an organization needs the composition of the following components:
A computer;
Power connection;
Software;
Video cameras;
Video signal processing devices, multiplexers.
Camcorders can be monochrome and colour. They are classified into several main types:
Digital;
Wired analog;
Combined with Wi-Fi transceivers or GSM;
Every video security system must include a video recorder. This is the device responsible for recording and storing information from the camera for a long time so that the security team can review them in future. The DVR provides various recording methods:
Continuous recording: mostly used in cash desks, banks, organizations directly dealing with cash;
While recording movement in the camera view;
Depending on the schedule created by the security team;
On alarm;
Additional components included in the video surveillance system
Matrix switches;
Thermal printers;
Uninterruptible power supply units;
Illumination devices.
Control panel for PTZ cameras;
Modulators;
Nowadays, the modern market offers a massive range of accessories for video surveillance system:
Thunderstorm protection ;
Extension cords and wires;
Thermal housings ;
Mounts and brackets for video cameras;
IR floodlights ;
Microphones;
Adapters.
Swivel mechanisms;
Some organizations tend to ignore accessories thinking it's just an unnecessary luxury. However, this approach is wrong since they provide many features which can transform the process of organizing video surveillance systems. It becomes especially important if the intrusion detection and prevention system is being designed independently. While choosing devices for installing the security system, it is essential to consider the quality of the devices, the manufacturer's brand, and a license's availability.
In what situations the video surveillance system does not violate the legislation of the Indian constitution
Most organizations and security companies are aware of the rules related to privacy and the prohibition on secret surveillance. This brings into question how to organize video surveillance without violating the law of the land.
To protect a private property, home, and other residential premises where there are no strangers, corporations can install video cameras without warning signs.
In organizations, shops and offices, it becomes necessary to inform visitors about the availability of video cameras for security purposes. Companies can easily achieve this by placing a sign about video recording at the entrance. The organization's responsibility is to familiarise its employees with the security system and obtain written consent from them for video filming.
Covert video surveillance is prohibited in India, and the sale and purchase of such devices can attract law and enforcement agencies.
Why organizations should hire a specialist
The modern market is outflowing with different types of video cameras: outdoor, indoor, miniature, protected and vandal-proof. According to their type, they can fulfil different tasks and are suitable for different installation positions. In the meantime, there is also a universal option that comes with a certain number of outdoor or indoor cameras and video recorders.
Not all types of camera and universal sets can solve an organization's security issues. Therefore, it's a must to take advice from a specialist or a dedicated security company while choosing security devices. A professional will assess the size of the room, the purpose of the cameras, and the client's requirements. He will also select the optimal devices with the demanded resolution, viewing angle and features.
What video surveillance systems are suitable for an office and other facilities
The choice of video intrusion detection and prevention system for an organization depends on the requirements and tasks. They can go for IP, HD or analog options.
IP cameras are famous for their clear image quality and unlimited expansion possibilities. In addition, many cameras can be connected to a single system. A single IP camera can also work independently without a DVR.
When it comes to image quality, HD cameras are usually slightly inferior to network cameras. However, their main advantages include cost, which, with comparable features, can be lower.
Analog systems are not being used for a long time within large companies, but they still haven't lost their relevance. They have the worst image quality, and they need to be changed, and in case of replacement with HD cameras, companies can also save on rewiring the cables.
The exact number of cameras and other essential devices depend on the complexity of the task. These security systems can be assembled on a fixed or motorized camera stand, adding a microphone and other equipment options.
