Roku TVs don't have Bluetooth, but that's because the TV manufacturer doesn't offer it. Roku doesn't build the TVs, so you can't blame Roku for that specific issue. To my understanding (and I certainly may be incorrect) is that the Roku wireless speakers use WiFi Direct to communicate with a Roku TV, not Bluetooth.
You didn't mention exactly which camera you tested, but I believe they all support adding a Micro SD card, so you can play the recorded video on a computer in that way. There are many surveillance cameras that offer the ability to send an HTTP stream for viewing on my computer browser, but there are many more that process through some sort of cloud service. My Ring doorbell cannot be monitored directly from a computer, but it too requires an annual subscription for their cloud services.
While I haven't seen all the different advertisements made for the new Roku Home cameras, but I don't believe they ever claimed to offer HTTP streaming directly from the camera. If that is a requirement for your use, then I agree it's not the correct device, and you should likely look elsewhere.
