Abstract: Devices and methods for managing multi-media files and associated metadata in a hybrid manner are disclosed. Methods for using the device(s) to implement different methods for managing information obtained (e.g., recorded) by a plurality of recording devices are also disclosed. This disclosure also relates to comprehensive use of multiple distinct surveillance systems in a coordinated manner. For example, a set of surveillance devices configured for use by one or more law enforcement agencies or other government agencies may share metadata to facilitate indexing, sharing, accessing, and coordinating potential surveillance recordings. In one example, metadata may be uploaded to cloud storage while associated multi-media files are maintained locally by the responsible agency. Maintaining metadata and actual multi-media content separately may reduce bandwidth transmission requirements and maintain confidentiality of surveillance recordings.

Abstract: Devices and methods for cloud based management of multi-media files and/or associated data files are presented. Methods for using the device(s) to implement different information management techniques for managing information obtained (e.g., recorded) by a plurality of recording devices are also described. A comprehensive use of multiple distinct surveillance systems in a coordinated manner is described. A set of surveillance devices configured for use by one or more law enforcement agencies or other government agencies may upload and share information using cloud information, storage, access, and security methods. Maintaining information using cloud based techniques allows for sharing access (securely and remotely) without redundant copies of information on physical media and may reduce bandwidth transmission requirements. Further, requirements for both chain of custody of evidence and confidentiality regarding digitally recorded evidence may be complied with.

Abstract: A storage device that is pre-configured to execute one or more related applications when connected to a computer device or system. The storage device may contain a suite of applications that are pre-configured to execute without requiring “installation” on the computer device or system prior to execution. The storage device may be a secure (e.g., protected) storage drive for use with the associated computer device or system. The secure storage drive allows access only when properly authenticated to the computer device or system attempting to access the secure storage drive. Additionally, other levels of authentication may be required prior to allowing access. For example, access may only be allowed if both the computer device or system and a user authenticated to the computer device are recognized by the secure storage drive.
