I recommend a Wyze camera. They aren't waterproof, so you'll have to put it somewhere dry. They connect via an app through WiFi and are live and have good night vision. They are pretty cheap, the cheapest is about 25 dollars on amazon. I have one at the front of my house.
Sky blue opaline pied. That is a young male, maybe around 2-3 months. Baby males have a solid colored cere, usually light purple or pink, while females have one with a light ring around their nostrils.
Pic for reference
I am thinking this little guy is male. I could be wrong but when I zoom in, it looks to be a solid light purple cere (fleshy nose). Baby male budgies usually have a solid cere while baby females have a whitish one with faint circles around the nostrils.
This picture demonstrates that.
