Will this be able to record up to 100 feet away? Will this allow me to record 24/7? If so, what do I need to do to set that up?

The Blink cameras have a field of view of 110 degrees - in the daytime, they provide enough visibility to identify an individual’s facial features that is 20ft away, recognize a person that is 32ft away, and beyond that depends on exact lighting conditions. At night, they provide visibility up to 20ft away depending on exact conditions. The range of the motion sensor is up to 15-20ft depending on exact conditions. The Blink cameras, when armed would record clips based on motion detection only. The Blink cameras do not offer continuous recording though you can leave the system armed for motion detection for any interval of time.
