Cctv Software Limits

Software Limits

The second technology that limits the number of remote users supported is the software of the DVR or IP camera software. Network DVRs and IP cameras both use embedded web server software to serve video streams to client applications, web browsers, and mobile apps. Just as a web server used to host web sites is limited in the number of users that can access a web page, the web servers built into surveillance equipment limited by the number of video streams it can serve simultaneously. Users need to also consider that the software of your DVR is also performing other resource intense operations such as recording video and managing all of the configurations rules related to recording and alarms.

Hardware Limits

Last, there is the limitation of the hardware. Even the fastest supercomputers available have limits to the number of processes they can handle at any given time. Most entry and mid-level surveillance DVRs use processors equivalent to the Atom processor, like the ones use in tiny netbook computers. And again, these processors need to handle a lot of important tasks such as continuously recording multiple video streams, activating recording based on alarm events like motion detection, and allowing users to playback and export recorded video. It is easy to see why these devices are limited in the number of remote users and video streams they can serve.
