I heartily endorse SS adding more CPU-consuming features, like person detection, fog & tree avoidance, and alerting me to cob/spider webs on the camera lens. I will likely bump the frame rate at some asked about the web interface I rarely use it as I have iOS devices/apps talking to SecuritySpy (I use SecuritySpy, Spyglass, and Remote Patrol - no real favorite). SecuritySpy consumes under 15% CPU, and the entire server generally runs under 20% unless Plex is making it work hard. I use non-rectangular motion detection masks, which may or may not matter for CPU usage. I currently have four 2MP cameras and two 3MP cameras, all H.264 8 FPS, motion capture armed on all 24/7. Aside from SecuritySpy the server runs Plex, an iOS caching server, and some lighter server processes. I use an HDMI dongle which I find helps performance, and I recommend if you haven't added one. Motion capture are done to a USB-attached Drobo.
I changed the system disk to an SSD, but that's only because my 5400RPM system disk failed after ~6 years. I'm using a headless 2011 Mac Mini (Server), 2.0GHz quad core i7, 16GB. And agreed, the Mac Mini makes a fine SS machine. Chrome across the various tabs & windows I have open uses more CPU time than Security Spy & VTDecoderĪgreed, interesting thread. My mini also runs Plex media server, MacOS Server, iTunes, BTSync (backup for family computers to mine), iTunes (wifi backups, and playback to airplay speakers) and still is on average 70-80% idle CPU. I have things set to keep everything for a month and it's only about 500 GB across all 6 cameras. With current 10fps the 720p cameras have 1 hour continuous capture files that vary from 275 MB up to ~760MB - a full day's capture+motion (video+pictures) looks to average 12-13 GB I had originally settled on 10fps a while ago to reduce file sizes - but with newer Security Spy plus mostly H.264 cameras, I can likely increase fps - will do some testing this weekend maybe and post with any changes seen. (at night it's closer to the 8-10% range, daytime with lots of activity/storm increases load of both processes)
Security Spy itself uses 8.5-20% CPU, VTDecoderXPCService using 9-25% CPU 2012 Mac mini quad i7 2.3 Ghz, 16 GB ram, 512 GB SSD + 1 TB HDD as fusion (plus 4 bay USB 3 external case with 2x2 TB HDDs mirrored dedicated for capture footage).Ħ cameras usually 2x Foscam FI9803 (one P, one EP, both 720p 10fps), 2x Foscam C1 (720p, 10fps), 2x Foscam 8910E (640x480, 10fps) - the 2 FI9803's doing continuous capture plus motion.Įverything responsive - will be upgrading cameras to higher resolution over the next year or so, and likely increasing count to 8 as well.
