Security is a major issue in the modern world. This is why digital security systems are such important tools. It’s difficult, however, to know where to start. A good place is to understand the basic differences between the systems.
The main aim of CCTV systems is to monitor and record what is going on within a specific location. Not all CCTV systems record or deliver data the same way. This is why the systems are classified into three types i.e. analog, IP, and digital CCTV systems. Let's take a closer look at them.
These are CCTV systems that have a lot more advanced features than analog systems. They can capture and record images digitally meaning that data does not need to be converted.
It is a surveillance system that can be accessed through a personal computer and in some cases, even on a phone. It uses a multichannel video recording that uses advanced technology. This enables the system to provide high-quality videos and pictures.
A unique aspect of multichannel video recording is that users can install several cameras on the system. The system is as large as the number of cameras installed on it. In other words, the system can be expanded by installing more cameras. The user can also view activities on all the cameras through a single monitor.
A CCTV digital video camera price will vary based on many factors such as its unique features and the company that produces it.
These are CCTV systems that use analog technology to transmit pictures and videos. The cameras capture images and then the signals are sent through a coaxial cable to a DVR (Digital Video Recorder)
It's the DVR that converts the images and video from analog to digital cctv system. It also compresses the files and stores them on a tape or hard drive.
To view the video, users need to ensure that the DVR is connected to a monitor. Alternatively, the video can be broadcast via an internal network over the internet using a router and modem.
Their main purpose is to record data. They generally aren't able to be accessed for live streaming in most scenarios and this essentially makes them less suitable for live monitoring. However, because the data is recorded on digital tapes, they can be viewed easily.
The major disadvantages of analog CCTV systems are;
Despite its many setbacks, an analog CCTV camera price isn’t very high. The cost will vary from company to company.
Often referred to as the security systems of the future, IP cameras are a type of digital surveillance cameras with some added features. It can convert audio and images and transmit them over an internet connection. This essentially means that multiple viewers can view all activity on the monitors in real-time.
This system is network-based and therefore allows users to monitor remotely or within a network. For this type of system, a network video recorder (NVR) is needed to record the data. It uses advanced IP cameras that produce high-quality images.
IP CCTV systems have several useful benefits including;
There are many factors that users need to consider when choosing to install a security system.
Many users install security systems to monitor activities going on within particular premises. In such cases, a digital camera-based system would be the better option. However, for a small or confined area with little activity, an analog system would be effective.
There is a huge difference in how the two systems are installed. Analog systems usually require a lot of wiring and are relatively difficult to install. Many Digital CCTV camera systems are wireless and are relatively easy to install.
Both digital and analog systems have useful benefits. Users need to choose either option based on their needs and preferences. Analog system owners can opt to switch to digital systems. The advantage of this is, that users don't need to invest in a whole new system, they can simply upgrade their old one.
