I recently upgraded my system to use H.265 compression. The difference in storage is significant compared to H.264! I've managed to cut my storage needs by almost half while still getting high-quality video. For anyone considering an upgrade, it's worth it. Just be sure your hardware supports it.
That's great to hear! H.265 does offer improved efficiency, especially for higher resolutions. Just keep in mind that you'll need compatible devices to fully utilize it.
I disagree with the idea that cloud storage is the best option. I've had issues with internet outages that made it impossible to access my footage when I needed it. Local storage is more reliable in my opinion.
I see your point. I think a mix of both local and cloud could be the best approach to have redundancy and access from anywhere.
Can you clarify how motion detection impacts storage needs? Does it really make a big difference?
Don't forget to factor in the network bandwidth! I had to upgrade my router because my cameras were slowing down the network.
