This is a fascinating question.
Years ago, Axis heavily emphasized TCO but that was in the context of competing with analog (e.g., Debating Axis's IP vs Analog Cost Comparison).
I do not recall Axis making any claims or assertions about their TCO vs other IP camera manufacturers. Of course, they are promoting their 'quality' but that's more soft stuff like 'an elephant can step on an Axis camera' or 'in video games, we're indestructible'.
Long-term quality is a potential differentiator for any premium manufacturer, and Axis is undoubtedly quite good but the problem is, all indicators are that Hikvision is quite good / reliable as well.
If anyone has any ideas on how they work compare TCO of Axis vs Hikvision, I would be curious to hear it.
Ok, so no one has offered anything. That's not good for Axis...
Hikvision's clear #1 problem is cybersecurity. Outside of that, Hikvision can go head to head with Axis on almost all mainstream applications.
Perhaps it would be an interesting question if Hikvision offers some official information about their products' mean time to failure which Axis does to their partners?
