«Our bank has undergone changes in its corporate security policy. Now we must store archived video for at least six months, rather than two months as before. We currently have a PC-based video surveillance system installed. We are considering two options: either expanding what we have or installing a new system using a DVR. Which option is the most advantageous in terms of price and capabilities? —

Since the user has experience using PC-based CCTV, I will focus on Stand Alone solutions. Today, DVR prices are quite comparable to the cost of computer solutions. And most importantly, this segment of the TSB market offers a wide range of devices with various functional characteristics and capabilities.
The higher the image quality and the longer the storage period of the video archive, the more hard disk capacity is required. In this regard, some modern digital video recording devices have the ability to expand the memory capacity to 30 TB, which ensures the ability to continuously record for several months even with the highest image quality.
It should be noted that modern DVRs, as a rule, have a Russified menu, as well as a convenient and intuitive interface, which allows even a novice operator to easily configure the recorder and manage its functions. All basic actions, including basic settings, camera selection, search, playback and copying of video files, are carried out using a regular computer mouse, which means that users accustomed to working with a PC-based system will not need to be retrained.
Another advantage of modern video recorders is fast work with the archive. The search is carried out according to the specified criteria. For example, the video recorder may have functions for searching video images by motion detection, alarm list, bookmarks or date and time. Moreover, you can simplify the search by motion detection by selecting the detection zone and sensitivity level. The on-screen calendar will help speed up the search by date and time. And to create bookmarks, the operator only needs to press one button.
In addition, when working with a video recorder, the operator can perform many actions simultaneously: monitoring, viewing previously recorded information, recording video, copying and transmitting data over the network. Thus, the user receives a real picture of events in real time without delays and hesitations.
