Traditionally, the DVR system is considered the safe and reliable option. Still, there are some key considerations regarding the use, maintenance, access and capacity of Digital Video Recorders.
How Do DVR Security Systems Work?
Coaxial cables are used to connect Digital video recorders to analogue cameras. DVRs have an encoding system and internal hard drive, meaning all footage can be stored and processed on demand and needed locally. Here are a few main features that will help you better understand working the DVR Security Systems.
Connects Directly to Cameras:
Each camera has to be connected individually, as DVR systems do not work wirelessly. Cables are used to connect the cameras to the device
Operates on a Closed Circuit:
DVR systems are not connected to the network like other modern systems are connected nowadays; they function as conventional security systems.
Captures Analog Pictures:
DVRs are primarily used with analogue cameras, but companies with existing systems are replacing and upgrading this hardware with better quality versions for more reliable results.
Processing of Video Data:
DVR systems such as the hikvision 7200 series use encoders to ensure the images captured by the cameras are stored and sent to the chosen storage destination of the enterprise.
Stores Footage on Hard Drives:
DVR systems must be configured to a PC or server, as these systems rely on on-premises data storage options.
Pros and Cons of DVR Security Systems
Though DVR systems seem to be outdated_ unlike other solutions for security surveillance_ the internet is not required for it. These security camera systems have evolved throughout the years, and like other technological devices, DVR systems have their own benefits and Challenges.
Benefits of DVR Camera Systems
Cost-Effective Set Up:
Compared to hybrid cloud and NVR, DVRs are affordable, especially for small businesses. The cost of a DVR system varies depending on the number of cameras required, but it can also be installed without professional help. This system also has some initial savings because these systems integrate with the lower quality cameras.
Secure Connections:
Since DVR systems do not require any internet connection to work, they can work almost anywhere, including the remoter locations, if there is a power source available. The lack of network connectivity also reduces safety risks, as hacking is impossible.
Instant Access:
DVR systems directly connects to the cameras, ensuring instant footage storage on the hard drive and making accessibility easier. Surveillance staff on-site can check and watch the footage as it’s been recorded
Special Features:
Though DVR may not appear as an advanced security solution, it has many features. For example, time-stamping capabilities and motion detectors_ mean the surveillance staff will no longer have to sit for hours to find a specific incident.
Challenges of DVR Camera System
Minimal Flexibility:
DVR systems need to be located near the power source, and sometimes businesses have limited options to install these as they do not use network connections. Footage has to be reviewed on-site or at the permitted storage-saving facility.
Maintenance Fees:
If a DVR malfunctions, it’s not a software issue but a hardware one, which makes the repair process expensive.
Clunky Wiring:
All DVR solutions require coaxial cables for the connection; the wires are large, which makes the installation in tight places difficult. They does support audio as well.
Other than this, lower image quality and less storage capacity are also weak points of the DVR security systems. All that is necessary is to make the right choice according to your surveillance needs, whether you are purchasing a Hilook colorvu lite or a simple DVR system. It should complement your security needs; if not, it doesn’t matter how much-advanced the system you install; it will be of no use.
