In most Security Cam applications the timeline feature is horizontal with older events to the left and more recent to the right. This suits PC based applications.

a horizontal timeline

In the mobile world timelines are vertical, think of Facebook and Twitter. New events are at the top older events are toward the bottom.
As the demand for mobile access to security cam systems increases we predict that the orientation of timelines will do a 90 degree flip and go vertical.
In our latest app “Timeline” we feature a vertical timeline. Timeline is the world’s first mobileVMS. No server or PC is required; everything runs on the mobile. Because there is no server or PC there was never any reason to build a traditional horizontal timeline, so we went vertical. Come and see this innovative app at IFSEC stand B110. We have a live demo running throughout the show.
