Where and how can I view and/or save the surveillance video?

As mentioned in the previous FAQ question, you can either opt for a video recorder or a live image. The recorder provides a full recording of the captured image until the hard disk is full. With a live image, you can watch video 24/7, but the image is not always recorded, with many systems, you can record short clips via an app. This can be controlled manually or recorded automatically when motion is detected. These clips are then stored in the app.
