Secure Video Stream Sharing for First Responders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Private surveillance networks are not accessible to emergency responders during critical situations, hindering their ability to receive real-time video feeds necessary for effective response.
Innovation Solution
A system that allows facility administrators to securely share video streams with pre-designated first responders by activating access through mobile apps and web browsers, using a secure API and permissions management to control camera meta data and video access during emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If private surveillance networks are kept inaccessible to the public and government, then privacy and security are maintained, but emergency responders cannot access real-time video feeds during critical situations
Solution Approach 1:
The system pre-designates first responder agencies and establishes authentication credentials before emergencies occur. When an emergency is detected, the system can immediately activate pre-configured video stream sharing without requiring real-time authentication or configuration changes, thus maintaining privacy during normal operations while enabling rapid access during emergencies
Solution Approach 2:
The surveillance system dynamically adjusts its accessibility based on emergency conditions. During normal operations, the system maintains private access controls. When an emergency is activated, the system transitions to a shared access mode, allowing pre-designated first responders to access video streams through authentication credentials and mobile applications
2Productivity
If video stream access is made available to first responders during emergencies, then situational awareness and response efficiency are improved, but system security and privacy control are compromised
Solution Approach 1:
The system segments video stream access into different levels and scopes. Administrators can select specific cameras or camera groups to share with first responders rather than providing complete system access. The system supports partial access to specific video streams, allowing targeted information sharing that minimizes security risks while maintaining operational effectiveness
Solution Approach 2:
The system introduces authentication credentials and mobile applications as intermediaries between the private surveillance system and first responders. These intermediaries verify the identity and authority of responders before granting access to video streams, ensuring that only authorized personnel can access the system during emergencies
3Loss of time
If continuous video access is provided to first responders, then real-time situational awareness is maintained, but system privacy and operational security are compromised
Solution Approach 1:
The system implements periodic or on-demand activation of video stream sharing rather than continuous access. Administrators can activate sharing during specific emergency periods and deactivate it when emergencies are resolved, ensuring that video access is available only when and where it is most needed, thus maintaining privacy during normal operations
4Adaptability or versatility
If multiple first responder agencies are granted access to video streams, then comprehensive emergency response capability is improved, but system complexity and access control difficulty increase
Solution Approach 1:
The system uses a universal authentication mechanism that serves multiple first responder agencies through a single integrated platform. Administrators can manage access for multiple agencies using consistent authentication protocols and permission settings, reducing the complexity that would otherwise arise from managing separate access control systems for each agency
Data Source
AI summary
A video surveillance service shares image streams with first responder agencies in the event of emergency. Nominated agencies establish access credentials at the surveillance service data center. A camera is shared by a customer administrator's selection of permissions on each camera via privileged web-browser or mobile device. Permissions enable selection by static meta data such as type, audio, location, motion, recognition, PTZR, spectrum, and epoch. Video streams of present and past epochs are controlled by ranges of time. A responding agency receives an electronic notification from the administrator to present their access credential and a handle for each shared camera of interest. A notification may be customized for each responding agency and each event by dynamically generating a link to a secure webserver which records geo-location or network identifiers for validation. Video servers include virtual machines dedicated to each responding agency but controlled by a customer administrator.
