Arlo video is very sharp and high fidelity. We lost our system in a house fire, but not before it got video of the arsonist. The video is uploaded to a cloud account, and that can be downloaded to your own hard drive or other storage. Arlo has a free plan where video for a week is stored on the cloud. Course, if you don't download it and it is beyond the week, it is gone.
You can watch it from anywhere using the web client, or smartphone client. And can download the video to your phone or computer.
Our video was so sharp that the prosecutor and public defender for the arson case recommended the arsonist plead guilty without contest (even though he first said - there was no proof and he was not there). He was found guilty and now is serving >10 years.
