The reluctance combined with the excuse is worth taking seriously, but there's a nuance everyone's missing: sometimes people genuinely have awful internet, bad lighting at home, or just feel awkward on camera. That's different from someone who's evasive about it. The key difference is whether they're offering alternatives or just shutting down the idea entirely.
If they keep dodging without any explanation beyond "I'm not a video call person," that's the actual red flag. Someone who's honest will usually say something like "my place is a mess right now" or "my internet's terrible" or even "I get really anxious on camera." The vagueness matters more than the refusal itself. I'd push back once, clearly and directly - something like "I'd feel way more comfortable with a quick call first, even just ten minutes" - and pay attention to how they respond. Do they suddenly find a reason they can make it work, or do they dig in harder?
The other pitfall is meeting them anyway if they keep deflecting. Don't convince yourself it'll be fine just because the texting feels good. If someone won't even try a five-minute video call to make you feel safer before meeting in person, that tells you something about whether they care about your comfort. Meet in public obviously, but honestly, I'd consider that a sign to move on rather than a puzzle to solve.
