Video surveillance from idea to ... idea. Data
The idea itself: "Video surveillance from idea to ... idea"
Here will be described the facts of the system. Pictures, logs, and something else.
The most difficult thing was not the optimization of algorithms, not the invention of a good system, but the struggle with the load average. Imagine you have 30 streams of cameras that write to disk, desktop disks in the raid on FreeNas via NFS. Creepy? No, not horror, even if without NFS, it is still a huge system drawdown. The solution is ramdisks.
Since the system has been lying dead for a month, and I slowly studied Java ( here ), I am not quite aware of how many cameras are alive and what is happening on the server. We will understand the course of the article. Do not let me go until the topic of video surveillance.

Here it is a cherished machine:
The picture shows that she has experienced many tests and loads (from Windows 2003 graphics to the minecraft server). Load average is shown in working condition, i.e. Now the cameras are working and the car is writing a video.
Here is the "working virtual horse" system. The idea was to multiply and run them in different parts of the "world". And if desired, embody in the gland. Unpacking qcow to disk seems to be a trivial task.

The most working horse in the current implementation is VLC (proceeded to the development of ffserve, but never completed it)
Caching cannot be set to less than 500 (ms), as there is some buffer in VLC that does not have time to fill with video data and they go to the return and destroy the video stream (there will be sound, there is no video).
Caches are chosen empirically.
--telnet - allows you to manage VLC via telnet.

CAM_12_lhttp is our cameras
12 - id from sql
CAM - essence
lhttp - stream
The logic of work is simple. Once every 10 minutes, delete the rec stream, create a new rec stream with a new file name. Video stream is cut.
New threads are added to the end of the list.
Here we see the CAM_11_mtn is the last - he is writing at the moment, as the motion said to write.
in the ~ / vlc directory there is local, nfs, tmpfs.
fstab explains who it is and what it is
local - Plain folder. It contains intermediate configs, logs, and proc flags (see the VLC startup command above)
[vlc @ dvr tmpfs] $ ls
Each directory has subdirectories where name is the user id from sql
each user has his information
img - image storage
lhttp - VLCshny hls
lock - files flags to synchronize all this zoo
motionDetected_11 - says that there is movement on the 11th camera.
update.lock - says that the update system is on
And for these files is a countdown. Time lapse, recording and more delays.
mnt, rec - current records. Let me remind you that this is a ram disk and we write 10 minutes in memory. If we don’t write, the folders are empty. As soon as 10 minutes passes, the file is migrated to NFS. After all, it is easier to throw a piece at NFS, rather than pouring streams from the cameras.
in tmp there are auxiliary files, or additional info for php, since we are not working as a daemon, but run 1 time in the update about the server.
From the pictures we make tayplapsy
While writing an article we have traffic (ls with NFS)
And this is what they recorded today.
Logs writes a lot. Not production after all.
The current load on the network interface (iptraf-ng) in-15000 kbps, out 1500 kbps.
FreeNas load:
Gigabit interface, worth ZRaid2 + hard body (ZLog?)
Freenas:
Intel® Core (TM) 2 Duo CPU E4500 @ 2.20GHz
Memory: 4006MB
Load average 0.15, 0.16, 0.11
Records
Green - permanent record
red - motion records
blue - timelapse
We look record on the movement. And the truth is movement:
And all events are put in sql.
That timelapse arrived in the last hour.
Duration 20 seconds.
You can see something like this:
If 1 hour can be viewed in 20 seconds, then 1 day can be viewed in 8 minutes.
This is how it is possible to collect something formalized and working from improvised means.
I do not spread the video as the cameras are private. In the screenshots there is a public space that anyone can enter.

Records
Green - permanent record
red - motion records
blue - timelapse
We look record on the movement. And the truth is movement:

If 1 hour can be viewed in 20 seconds, then 1 day can be viewed in 8 minutes.
This is how it is possible to collect something formalized and working from improvised means.
I do not spread the video as the cameras are private. In the screenshots there is a public space that anyone can enter.
