DVR

DVR is a shorthand in the form of Digital Video Recorders. They let you capture the security video that the CCTV security camera records and allow you to view it again when you need to. This is crucial to the security of your site. If there is an incident of security risk or crime the DVR can ensure that you have security footage to show the evidence that can allow you to recognize the perpetrator. Businesses of all sizes must make an effort to regularly back their data since it will protect your data in the case of physical damage or theft. The DVRs available today are typically capable of recording video that comes from as many as 16 security cameras at the same time and is referred to as multi-channel recording'. DVRs are also often equipped with hard drives which allow users to save and backup the footage you've recorded. Additionally, more sophisticated DVR models will also provide cloud storage or come with apps to help you watch live streams even when away from your computer.

What is the resolution feature in a DVR system?

Something to keep in mind when looking at the resolution features of the DVR system is the frame-per-second measurement since this can help you ensure that your security footage that you record is of sufficient quality.'Frames per second' are basically the number of still images that a DVR can record in a single second. The stills are then reassembled into an audio-video. While this might sound outdated, this is how video footage is created - even in Hollywood. The typical USA Broadcast film is made in 30 frames/second. This means that every second includes 30 still images linked in order to create the appearance of a flow. The more powerful the FPS number greater the quality of the image. Since DVRs are the ones responsible for recording video footage, you have to make sure you're choosing the correct FPS. In general, DVRs permit you to select the FPS you want so you can test and test the needs on your website. Be sure to discern faces, specifics, and any changes in high-risk zones. It's also not unusual to see DVRs marketing materials to refer to 400 FPS. This may sound shocking, particularly when you compare it to the 30 FPS of Hollywood Blockbusters it is just a way to say that the DVR is able to accommodate 400 FPS, however this number will be divided over the amount of cameras for CCTV that you have installed on your website. In other words, if you've got 20 cameras for security, every one of them will be able to achieve an FPS of twenty (400 FPS split by the number of security cameras).
