Abstract: Example aspects include a method performed by a newly-added device to a private network of a communication system. The method includes generating a self-signed digital certificate. The method further includes receiving, from a mobile configuration device, via a first short range wireless communication, a request for the self-signed digital certificate. The method also includes transmitting, in response to the request, via a second short range wireless communication, the self-signed digital certificate to the mobile configuration device. The method additionally includes performing, via the self-signed digital certificate, a handshake protocol with an existing device on the private network, the existing device having received the self-signed digital certificate from the mobile configuration device.

Abstract: A surveillance camera and surveillance data management system includes a video management system with a data retention module for determining when surveillance data is deleted. Blocks of the surveillance data are deleted based on the ages of the blocks, which are calculated based on the difference between a recorded start date for each block and the current time and adjusted to subtract durations of periods of system downtime that occurred since the start date. The ages are also calculated using a counter, which is initialized to a predetermined value for each block and incremented or decremented only during uptime. In another embodiment, an override module determines an override status based on input from an interface, which can include a physical switch or a keyboard, mouse and display, and returns the override status. No surveillance data is deleted when the override status is true.
