Quoted from Leeb18509:
It's not designed to record 24/7. That's not what they do. They detect motion and then start recording for up to 60 seconds. I have mine set to record for 20 sec at a time and it's plenty. 2 hours is 240 thirty seconds clips. Would you rather pay Nest $15 a month? I have literally hundreds of clips stored up and I set it to delete them after 7 days. If you want to save something, it's very easy to send it to your email or a text message. I use them to see who's at the front door, the back door, and keep an eye on the garage when the door is open. The app is excellent and the picture is fine at 720p, no issues accessing clips or receiving them to view seconds after whatever happens. Is bandwidth really an issue these days? "You've got mail!"
You're thinking about downstream (from the cloud to your phone). That's no problem for most.
However, upstream bandwidth (from the camera to the storage cloud or directly to your phone) is an issue for likely 80% of the population or more, still. Most packages are not symmetrical bandwidth. Carriers like Spectrum/charter will give you 100mbs down, but 2 or 5mbs up. h264 at 720p will eat up most of a 2mbps stream. DSL and wireless is even worse. So yeah, h.264 is a bad choice. h.265 is the one to have and will likely be more widely deployed in cheap cameras this coming year.
240 clips/year is much less than one 30 second clip a day. It's just about exactly worth the free it costs. For a very low-traffic area it would be fine, but that's about it.
