41.The Network Video Recorder software shall be designed to provide both redundancy and high availability as standard built-in features.
42.The Network Video Recorder software shall include configuration support for up to two levels of automatic storage fail-over. In the event that the designated primary storage encounters a problem, the system shall automatically switch to a designated level one storage device to provide continuous recording. In the event that a problem occurs with level one storage device, the system shall automatically switch to an alternative designated level two storage device. The optional storage fail-over drives must be setup on the Network Video Recorder.
43.The Network Video Recorder software shall include server-based fail-over support for 1-to-1, many-to-1 and many-to-many configurations. When a Network Video Recorder is setup to be a standby fail-over server, it shall be setup to monitor one or more active Network Video Recorders. When a failure is detected, the standby fail-over server shall automatically take control over all cameras and provide the same user and access rights as the failed server. The standby fail-over server shall have its own storage resources, be on the same network segments, and licensed to support the Network Video Recorder with the largest number of camera slots.
44.The Network Video Recorder shall be designed to provide a very secure environment.
45.The Network Video Recorder software shall operate as a secure enterprise IP appliance server designed to operate on a hardened and embedded Linux operating system, shall not accept any keyboard or mouse input at the physical server, and utilize true server-client architecture to provide a "lights- out" operation.
46.The Network Video Recorder software shall not be susceptible to daily patch management like other standard distribution operating systems. This shall reduce the administration overhead for each Network Video Recorder as well as limit the exposure to security risks.
47.The Network Video Recorder software shall function in a read-only mode to all users and administrators of the system. This shall provide stronger protection against virus and other malicious programs. This also eliminates the recurring cost for third party security software such as anti-virus, anti- spam, firewall, spyware, and intrusion prevention.
48.The Network Video Recorder software shall provide no file-level access to all users and administrators of the system. This shall protect against deletion
