Sometime, the process sswebstreamd crash, and DVA doesn't work, but facial recognisation is OK: 2024-04-10T10:56:43+02:00 DISKSTATION coredump[18022]: Process sswebstreamd[22665](/volume1/@appstore/SurveillanceStation/sbin/sswebstreamd) dumped core on signal [11]. Core file [/volume1/@sswebstreamd.synology_geminilake_dva1622.69057.core.gz]. Cmdline [/var/packages/SurveillanceStation/target/sbin/sswebstreamd ] 2024-04-10T10:56:47+02:00 DISKSTATION coredump[18022]: Core file [/volume1/@sswebstreamd.synology_geminilake_dva1622.69057.core.gz] size [33706015] I need to restart SS package for restore the DVA process with command systemctl restart pkgctl-SurveillanceStation Do you have this problem ?

I edit the file syno_localinstall_dsm.sh in usr/syno/sbin with # in 3 last lines to solve the fist one because it's a permanent useless ping. For "synobios get empty ttyS current" I found the problem in ACPI bios

I search a solution for speed up license plate. I read that DVA3221 can read at 40km/h a vehicule. But on mine DVA1622, the car speed must under 5 km/h for detect license plate. I found model.xml in directory /volume1/@appstore/SurveillanceStation/dvacore/etc/model/PlateDetection but I show nothing in openvino documentation

I can make 4/5 task for a CPU à > 90%, but it depend of resolution of task, area size and fps. On 4K it can more than 100% of CPU core if area is too big. I test facerec on my 1080P cam with a full area zone: 5 fps: 20% of one core 15 fps: 70% 25 fps: 90% You can test it with command "htop" and filter "synofaced"

Thank, but I already tested and same problem Before I change my N3150 hardware by a J5040, I only had the "synobios get empty ttyS" log, but now I have in addition the "syno_localinstall_dsm.sh" in my log. I disable all serial interface in bios, but flood log stay.

Hello, I have exacly the same in my logs, do you found the solution to stop these ?

Yes I use my old mpcie ASM1062 x2 SATA (see my last post) with x1 SATA build-in PC and x1 msata build-in PC, but I use only 3 drives in SSD format. I just test with 3 tasks AI at this moment, and CPU up at 80% but stay at 2Ghz max, turbo doesn't seen to work. For people interested, you can buy this mini PC here: https://fr.aliexpress.com/item/1005006220488959.html (the msata slot is on the other side of motherboard, you have MSATA + MVE/M2 + MPCIE SLOTS !)

I found the problem, when I renamed this 2 process, these missing: mv /volume1/@appstore/SurveillanceStation/synodva/bin/synodvad.old synodvad mv /volume1/@appstore/SurveillanceStation/synodva/bin/synofaced.old synofaced So, I reinstalled the SurveillanceStation-x86_64-9.1.4-11002_openvino.spk, and it work now !

Ok, I received my new mini PC J5040, all work mpcie 4x SATA ... but AI not work I run with the loader arc and i915 drivers

For foodies I also found this for less $20, you can up to 7 SATA drives on ALI mini PC ! https://fr.aliexpress.com/item/1005005653706057.html

If you need msata support a this mini PC, you can buy for $3 a M.2 NGFF to MSATA here: https://fr.aliexpress.com/item/1005005890645530.html

I don't need M2 or msata, only mPCI slot is usefull for me, because I use 3x SATA SSD drives And finally I order the J5040 because J4125 is out of stock

I found lot of mini PC with J5040 with prices 110-140€: https://fr.aliexpress.com/item/1005006311813456.html but it's M.2 2280 + 1 SATA, and miniPCI is under the M.2 2280, so no ASM1062 support or, only ASM1062 support with no M.2 2280 If you buy this: you can up to 5x SATA with this miniPC with a J5040 power !

I use actualy a baremetal with minipci x2 SATA and it's work fine ! lspci -nn 0000:03:00.0 SATA controller [0106]: ASMedia Technology Inc. ASM1061/ASM1062 Serial ATA Controller [1b21:0612] (rev 02)
