+ | **Q:** What are the options for using WolfRecorder and what is it for?\\ | ||
+ | **A:** [[usecases|Something like that.]]\\ | ||
+ | |||
+ | **Q:** What is the cost of this solution?\\ | ||
+ | **A:** WolfRecorder is a free and open source software.\\ | ||
+ | |||
+ | **Q:** Are there any artificial camera quantity limits?\\ | ||
+ | **A:** No.\\ | ||
+ | |||
+ | **Q:** How many cameras can WolfRecorder record?\\ | ||
+ | **A:** This depends entirely on the performance of your storages and the architecture of the cluster you built.\\ | ||
+ | |||
+ | **Q:** Can you give us some examples of the possible number of cameras per server?\\ | ||
+ | **A:** In real life, we already have NVRs running on used servers, 8-10 years old, with few hundred cameras on 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.\\ | ||
+ | |||
+ | **Q:** How is the available storage space distributed among the video captured from the cameras?\\ | ||
+ | **A:** Equally within each storage. By default for video archive is reserved 90% of storage space.\\ | ||
+ | |||
+ | **Q:** How can I determine the load on my storage? I mean, how can I determine if Disk IO or write speed is a bottleneck? | ||
+ | **A:** Well, for example, you can use the gstat command. | ||
+ | |||
+ | **Q:** What regulates how long the video archive of each camera is stored?\\ | ||
+ | **A:** It depends only on the size of the storage and video bitrate.\\ | ||
+ | |||
+ | **Q:** How can I calculate how much disk space I need to record a certain number of days of video from my camera??\\ | ||
+ | **A:** A 1Mbit/s bitrate generates approximately 11 gigabytes of data per day. Accordingly, | ||
+ | |||
+ | **Q:** What is the recommended OS for installing WolfRecorder? | ||
+ | **A:** FreeBSD.\\ | ||
