System Requirements¶
To calculate the FindFace Security host(s) characteristics, use the requirements provided in this chapter.
Tip
Be sure to learn about the FindFace Security architecture first.
In this chapter:
Basic Configuration¶
Important
If the resolution of a camera(s) in use is more than 1280x720p, it is strongly recommended to use the GPU-accelerated findface-video-worker-gpu package.
| Minimum | Recommended | |
|---|---|---|
| CPU | Intel Core i5 CPU with 4 physical cores 2.8 GHz | Intel Xeon E5v3 with 6 physical cores, or higher or similar CPU |
| The own needs of FindFace Security require 2 cores HT > 2.5 GHz. The characteristics also depend on the number of cameras in use. A single camera 720p@25FPS requires 2 cores >2.5 GHz. AVX support | ||
| GPU (optional) | Nvidia Geforce® GTX 1050 Ti with 4Gb RAM (only for running
findface-extraction-api gpu-package with elderberry_160, not
enough for findface-video-worker-gpu). |
Nvidia Geforce® GTX 1080+ with 8+Gb RAM |
| Supported series: GeForce (from Pascal architecture), Tesla (from Pascal architecture and Volta v100) | ||
| RAM | 8 Gb | 16+ Gb |
| The own needs of FindFace Security require 8 Gb. The RAM consumption also depends on the number of cameras in use. A single camera 720p@25FPS requires 2 GB RAM | ||
| HDD | 16 Gb | 16+ Gb |
| The own needs of the operating system and FindFace Security require 15 GB. The total volume is subject to the required depth of the event archive in the database and in the log, at the rate of 1.5 Mb per 1 event | ||
| Operating system | Ubuntu 16.04 x64 only | |
Tip
For more accurate hardware selection, consult the FindFace Security resource consumption and performance benchmark results.

| 2x 720p25FPS + 2x 1080p25FPS | 1750 | 590 | 21 |
Important
If video processing speed is less than the number of FPS in video, it means that the system is running low on resources and the lack of resources causes the video face detector to drop frames. Avoid this situation as it can lead to missing out on faces, instability and potential failures.
To check your resource consumption, execute:
sudo journalctl -f -a -u findface-video-worker | grep dropped
The following lines indicate that the system has less resources than necessary:
findface-video-worker[28882]: [2] 2 frames dropped!
findface-video-worker[28882]: [1] 6 frames dropped!
In this case, consider to change component settings or hardware configuration.
GPU RAM consumption and speed: findface-video-worker-gpu

Important
If video processing speed is less than the number of FPS in video, it means that the system is running low on resources and the lack of resources causes the video card to accumulate frames in its memory. Avoid this situation as it can lead to instability and potential failures.
To view the current processing speed, execute the following command on the findface-video-manager host console:
curl -s http://127.0.0.1:18810/jobs | jq -r '.[]|("id="+(.id|tostring)+" url="+.stream_url+" FPS="+(.statistic.processing_fps|tostring))'
In the response, you will find each video stream processing speed. For example, enough amount of resources when processing 7 video streams with characteristics h264 (High) ([27][0][0][0] / 0x001B), yuvj420p(pc, bt709), 1920x1080, 25 fps, 25 tbr, 90k tbn, 180k tbc will result in the following response:
id=10 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=27.189745
id=5 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=27.189854
id=6 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=27.589714

id=9 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=27.189857
Lack of resources when processing 8 video streams with the same characteristics will give FPS (processing speed) less than the video’s 25 fps:
id=8 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=23.772333
id=10 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=23.772415
id=5 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=23.772339
id=6 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=23.372803

id=9 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=22.573729
Even smaller values will be registered when processing 10 video streams with the same characteristics:
id=7 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=20.380642
id=9 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=20.380642

id=6 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=20.380642
id=1 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=20.380651
id=3 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=20.180836
id=4 url=http://restreamer.int.ntl/hls/openspace.m3u8 FPS=19.581406
Important
If findface-video-worker-gpu processes video streams of equal FPS, the number of processed streams doesn’t severely affect the GPU memory consumption, as all the streams are processed by the same worker. On the other hand, if findface-video-worker-gpu processes video streams of different FPS, it severely increases the memory consumption as different streams have to be processed by different workers.
Examples of Hardware Configuration¶
Important
The exemplary hardware configurations in this section are only for reference. Do not use these data to select your production instance configuration. To select the optimal configuration, ask advice from our experts by support@ntechlab.com.
Resource consumption may vary depending on the following factors:
- The number of HTTP requests per second, sent to
findface-extraction-api(depends on the number of faces in a camera field of view, the number of user search requests, etc.). - Video quality (video interference, colourful video background take up more resources).
- Motion intensity in video.
The following examples are given for standard component configuration.
Important
Changes in component settings may result in significant changes in resource consumption.
