What happens during the ProConnect initial boot-up

The AvertX ProConnect software uses the Linux operating system (OS), which allows for a fast boot-up process. The majority of the boot-up process is seamless/unnoticeable from a visual standpoint.

Here is a brief overview to help understand what the NVR is doing at initial boot-up:

  1. The NVR will attempt its Power-On Self-Test (POST) sequence, which loads the basic input/output system (BIOS) and Master Boot Record (MBR).
  2. Then it will load the GNU GRand Unified Bootloader (GRUB): a Multiboot boot loader. GRUB provides boot menu options for the Linux-based ProConnect NVR.
  3. Next, the unit will attempt to run the Kernel, which is the core interface between the hardware and the software, and mounts the root file system.
  4. Lastly, the OS will run Init (short for initialization), which essentially boots into software level programs such as the AvertX ProConnect software.

During normal operations, the process listed above runs as background information prior to booting into the ProConnect software.  Occasionally, the display may show information like this to provide a brief update on what the boot sequence is processing:
