As you can see from our picks, the top-rated pet security cameras can cost around $200. If you have a large home, you must factor in the cost of buying several of them. Keep in mind that some devices in this category require an additional fee to store video recordings in the cloud. We break down any extra fees in our reviews, so it's worth reading each of those closely. The good news is that prices are coming down. If you're not looking to spend a lot, you can get a general-purpose home security camera like the TP-Link Tapo Indoor/Outdoor Home Security Wi-Fi Camera C120 for around $40, or a pet-specific one like the Petcube Cam 360 for around $50.
