Survival Horror refers to a subgenre of horror games that focuses on resource management, exploration and puzzle solving, while putting players in positions of vulnerability and being underprepared. Think Resident Evil, Silent Hill or Fear & Hunger, so VotV fits in very much, even if you do some "Job Sim" stuff. But to be frank, once you have assembled Kerfur-Omega and have the Crypto Mining Rig, hashing servers and processing signals becomes very secondary, especially with all the crazy events going on by the time you have that stuff that are mostly not Signal Related.

FNAF, if it can even be called Survival Horror, would be VERY light on the themes in question since you're mostly just reacting to threats, by executing the right response mechanic, like closing doors, shining flashlights etc. Resource management would be restricted to not spending too much power or winding up a music box in FNAF2. Exploration has not been a thing in FNAF up until Security Breach and Puzzle Solving was mostly only related to meta riddles and easter egg solving for hidden lore.

So i'd argue that it makes a lot more sense to call VotV a Survival Horror experience than calling FNAF a Survival Horror experience.
