Exploring the Best Camera Setup for Outdoor Security

As a new homeowner, I’ve been diving into the world of smart home security, and cameras are at the top of my list. I’ve read through numerous threads and have a good grasp of what most of you recommend for a solid multi-camera system integrated with Vera. I’m planning to go with 6-8 POE Hikvision cameras paired with Blue Iris and a dedicated PC, but I’m curious about the current landscape for purchasing these cameras. Are there significant differences between models sold in China versus the USA, especially regarding firmware issues? I’ve noticed prices vary widely on platforms like eBay, and I’m not sure if some sellers are still shipping from China, which might complicate things. Any insights or recommendations on where to source these cameras would be invaluable. Additionally, I’ve heard about Arlo and Homeboy cameras as alternatives, but I’m not sure how well they integrate with other systems. If anyone has experience with these or similar setups, I’d love to hear about your experiences and any tips you might have. Thanks in advance for your help!
