I got a kasa camera from amazon for about $25. It's pretty limited- no battery, needs to be plugged in (but does come with a long cord), doesn't record unless you load it with a micro sd card. But all I wanted was live audio and video of the dog crate, so it's perfect for that. It's cheap enough that you could get multiple to cover different angles. https://www.amazon.com/dp/B08GH9KL4M?psc=1&ref=ppx_yo2ov_dt_b_product_details
