Dynamic Script Manager for Video Surveillance Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video surveillance systems are inflexible and require extensive, tedious setup, making it difficult to adapt to changing devices and system resources, as they need to anticipate all possible events and responses beforehand, leading to high setup costs and labor expenses.
Innovation Solution
A distributed video surveillance system with a script manager that creates and executes scripts dynamically by filling in parameters based on detected events, allowing for remote control of cameras and adaptation to current system states, using a template script that is completed with data from associated devices when an event occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hardwired and preset surveillance system is used, then system reliability is improved, but device complexity and setup difficulty increase significantly
Solution Approach 1:
The system transitions from static, hardwired configurations to dynamic, software-based scripting. Scripts can be modified and executed dynamically without physical reconfiguration, allowing the system to adapt to changing surveillance needs while maintaining reliable event response through standardized script execution mechanisms.
Solution Approach 2:
An introduction of a centralized management system acts as an intermediary between event detectors and surveillance devices. This mediator receives event notifications, selects appropriate scripts from a library, fills in device-specific parameters, and executes the corresponding scripts, thereby simplifying the overall system architecture and reducing setup complexity.
2Adaptability or versatility
If all possible events and responses are predetermined during setup, then system adaptability decreases, but setup time is reduced
Solution Approach 1:
The surveillance response logic is segmented into modular, reusable scripts that can be independently configured and stored in a library. Each script handles a specific type of event or response, allowing the system to combine and execute only the relevant scripts for each detected event, thereby reducing setup time while maintaining high adaptability to various surveillance scenarios.
Solution Approach 2:
The system uses parameter-based script configuration where generic scripts contain placeholders for device-specific parameters. When an event occurs, the management system dynamically fills in the appropriate parameters (such as device IDs, locations, and response actions) before executing the script, enabling flexible adaptation without requiring separate pre-configured scripts for every possible event scenario.
3Adaptability or versatility
If equipment changes or device unavailability occurs, then system flexibility is reduced in hardwired systems, but setup costs increase
Solution Approach 1:
The system employs universal, parameterized scripts that can work with multiple types of surveillance devices and event detectors. A single script template can be adapted to different devices by changing parameters rather than creating device-specific scripts, allowing the system to accommodate equipment changes and substitutions without requiring expensive reconfiguration or additional setup costs.

AI summary
A method and system of controlling a video surveillance system comprising providing a distributed video surveillance system having a plurality of devices, building a script having a parameter that is filled in when an event occurs, storing the script, detecting the occurrence of an event, loading data related to a first device from the plurality of devices in a first parameter to generate a first script, the first device being associated with the detection of the occurrence of an event, and executing the first script.
