What is DVR?
DVR is a wonderful device that records video to your local storage device. It amazingly records video in a digital format and later stores the footage on an SD card, a USB drive, or other storage devices. Regarding home security, DVRs allow you to record video from security cameras. DVR also allows you to save and access recorded videos later. You can easily connect a DVR to your analog camera using coaxial cables. One of the great benefits of using DVR for your property security is the ability to search recordings of events by date and time.
How does DVR work?
The working of DVR is very simple and smooth. It works by transforming analog videos into digital data for storage. DVRs can work using PC-based and Standalone systems. The property owners widely used the PC-based DVRs where they simply install DVR card. On the other hand, a Standalone DVR system does not need any PC. You only need a monitor to hook up to the system. One best thing about DVRs is the number of cameras that you want to hook up. You can attach any number of cameras with your DVRs according to your budget and needs. The entire process of working with DVR is as follows:
Signal Capture:
DVR receives analog signals from the security cameras and other sources of digital sources, i.e. televisions or other video input devices.
Analog-to-Digital Conversion:
First DVD receives signals and then converts these signals into digital format using an analog-to-digital converter. The conversion process of digital format involves sampling the analog signal regularly and assigning digital values to represent the video content.
Compression:
The digital video data is compressed using various encoding techniques to reduce file size while retaining visual quality. Compression methods like MPEG (Moving Picture Experts Group) are commonly used in DVRs to store video data efficiently.
Storage:
The compressed digital video data is stored on a hard drive or other storage media within the DVR. This storage allows for the retention of recorded video content for future playback.
Playback and Access:
You can access the stored digital video content through the DVR’s interface. You can play back recorded videos, pause, rewind, fast-forward, or delete recordings as needed.
Decoding:
When playback is initiated, the stored digital video data is retrieved from the storage media and decoded back into a format that can be displayed on a screen or monitor. This decoding process reconstructs the compressed data into a viewable video format.
