32, 64 and 128 channel CCTV "Line IP" for large facilties

Line application for video surveillance has now become more convenient for installation at large facilities. New card nominals for 32, 64 and 128 IP cameras allow activating many cameras with a single code from a single video server simultaneously. Please note that when activated, the license data cannot be separated.

New denominations are available for purchasing at our "Virtual warehouse":

Many IP cameras may be connected to the same server, if the sub-stream is connected with the recommended resolution of 320 × 240. The minimum resolution is only displayed in the multi view mode, when the camera maximized, it will automatically switch to the main stream with the maximum resolution. It is also necessary to use the 64-bit version of the operating system (Windows or Linux).

Timelapse with the use of a video-surveillance camera

New feature Timelapse is now available to the users of the Line service for creating live broadcast at the website. It may be used for creating a video from a series of frames from your video-surveillance cameras. As a result, you get a time-lapse video, and a short video may contain a period of several days, or even months. This feature is enabled upon request.

Unlike the test version that some users may have already tried, there have been several significant upgrades. In the free version, the maximum archive depth is 10 days with circular recording. Each frame is made once in ten minutes. The file is created every 24 hours, and the output video bit-rate is 2 MB/s. Also, the Line logo is removed from the video.

There is also a paid version with unlimited archive depth for the paid period, and individual settings: frequency of creating frames, time of record creation, and video bit-rate.
