I wish I could help. Mine aren't Lorex and from my (much shorter time spent) Googling, I came up dry too. It looks like they just want you to use their NVR - of course

Perhaps someone else here has already run into this.

While it won't help you at all, this is what mine looks like:

Looks like these Lorex do not have the setting, unless its buried somewhere else!

Vodoo magic...

I'm an engineer and ever since middle school I have found unit analysis very helpful. If you look at the units on a number (ie km/hr) you can usually easily figure out how to get hrs by simple * and /.

The reason I bring this up is that I am ALWAYS annoyed by the lack of clarity on units in this setting in particular.

I have always heard that it is the interval that key frames are saved. So if you have raw 30 frames per second stream, then perhaps you want 1 key frame for every 30 real frames (or one key frame every second).

So what are the units?????? Who the heck knows. I never understood.

Sorry for posting this old thread. Did you ever figure this out? I have a bunch of Lorex cameras as well and cannot change the keyframe/frame interval since there is no setting in the cameras for it. My ratios at always at 0.50 no matter what I do.

Found this through a search on another site:

turns out that that tho the UI is dumbed down, the underlying (Dahua) API still mostly works, so one can use commands to set things the GUI may not present, like I-frame interval (called GOP in the API):

for example, this gets you the current configuration (note that "GOP" stands for "Group of Pictures"):

and on my Lorex E891ab, this returns the following:

Are you going to record 24/7, or only on motion or other interest? I changed my BI-setup recently to use substreams for analysis and record only alarms in high definition (3.1MP to 8k). My camera setup is single 8k Reolink, single 4.1MP Honeywell, two 3.1 MP MileSights and two 4.1 MP HikVisions. My BI-computer is Asrock DeskMini 300 with Win11, Ryzen 3 3200G cpu, 32GB RAM, single 128GB SSD as system disk and single 2.5" 500Gb 7200rpm laptop hard drive for recordings. HDD isn't even NAS-variety, just recycled it from my old Lenovo workstation laptop.

I'm using direct disk recording (h.264 or h.265 depending on camera). I have CodeProject.AI to recognise objects and have Google Coral USB. I have set camerra buffer RAM to around 18Mb per camera and using five second pre-recording. Google Coral cost me about 60€, since I had time to wait. Codeproject and Coral are somewhat experimental still.

Previously, when I used main streams for all purposes, processor load was around 35%. After changing to sub streams for analysis, processor load is around 2-3%. Difference between substream and mainstream is such big that it can differentiate between using old hardware, or buying new! It definitely shows in electricity use in common energy efficient household. Ryzen 3200G is low end cpu by all means, but with good system architecture, it's able to do some heavylifting!

So, my suggestion for this case and everyone else, check the substreams!
