 +**Q:** How does it work? What is the prototype of this solution?\\
 +**A**: Works {{:dashcams.jpg?linkonly|like this}}. That's the primary [[https://en.wikipedia.org/wiki/Dashcam|source of inspiration]]\\
 +
 +**Q:** Can I try it out without installing it on real hardware?\\
 +**A:** Yes, you can test WolfRecorder in a virtual machine to explore its functionality before deploying it on production hardware.\\
  
 **Q:** Are there any artificial camera quantity limits?\\ **Q:** Are there any artificial camera quantity limits?\\
 **A:** No.\\ **A:** No.\\

 **Q:** Can you give us some examples of the possible number of cameras per server?\\ **Q:** Can you give us some examples of the possible number of cameras per server?\\
-**A:** The short answer is that a 200-400 cameras on an average server from this decade is not a problem. In production, we already have NVRs running on used servers, 8-10 years old, with 2-3 hundred cameras on each of them. Yep, thats about 0.4-0.5% per camera one core load, on CPU like Intel Xeon E5-2430L or about 0.6-0.7% core/per camera load on CPU like Intel Xeon x3440 from 2009.\\+**A:** The short answer is that a 200-400 cameras on an average server from this decade is not a problem.

 **Q:** What camera recording modes or schedules are supported?\\ **Q:** What camera recording modes or schedules are supported?\\
-**A:** Only continuous recording. Our position is that if the camera is enabled, all data from it should be saved and available at any time when it is required. That is why the project is name is WolfRecorder and not WolfSometimesRecorder or WolfMaybeRecorder.\\+**A:** Only continuous recording.

 **Q:** How is the available storage space distributed among the video captured from the cameras?\\ **Q:** How is the available storage space distributed among the video captured from the cameras?\\
