Acronyms are not the same as the English language as they are not words by themselves but compressions. "Closed-circuit television" is self-evident to a reader; CCTV isn't. And "in the context", yes, but readers are not necessarily experts in their fields. This is why many news publications usually expand acronyms.

So to be clear, I think that it would make sense for Frigate to define NVR the first time they use it on their site. However, this isn't a news publication and I really don't think it's unreasonable to expect any serious visitor to the Frigate site to be expert enough to know what an NVR is.
