Standart player for NOUS NF9 (SAMOON B03F) is kind of minimalistic one. Firmware contain some older version with internal numbers 5.5.0. CD shiped with DVR contain newer v2.2 with internal numbers 5.7.1. Both are looks more or less same.

And contain same bugs with google maps integrations. That makes work with this application painful.

Open Stack Cloud at home

There is a lot of options now exist about how to get virtual machine running. That including oldschool VMWare or VirtualBox VM setup.

More modern way is to use Vagrant or Docker. that is not just virtualisation, but also catalogs of OS/software that might be started in couple of clicks.

It is also not a problem now to create own small cloud with bunch of virtual machines that may run continously, be enlarged or shrinked if needed. easily stoped and destroyed and created again. Something like AWS EC2 but at home. One of such solution is DevStack on single PC. It is not as relible as as commercial public clouds (GCP or AWS), but for some personal testing purposes is good enough.

Prology iReg-7570SHD

Compact DVR with Ambarella A7LA70 and Omnivision OV4689. Have small LCD with plastic cover and tiny accumulator. Also have external GPS in the middle of the power cable. GPS and DVR holder compatible to Koonlung C-series DVR. Some special “soft touch” plastic that looks like leather on device’s front. Loud speaker. SDXC support. Work with exfat 128 GB cards. It is hard to release DVR from holder even using 2 hands. Device is not compatible with iPad and Lightning to SD Card Camera Reader because of long filenames (maybe fixed by firmware customization, see end of the post).

Video quality is OK as for the 200$ price.
