CVSS Video Management Systems (VMS) & Software 1 — Questions and Answers
Question 1: Which VMS architecture places all video processing and storage on a central server rather than on edge devices?
- Decentralized VMS
- Hybrid VMS
- Centralized VMS (Correct answer)
- Cloud-only VMS
Correct answer: Centralized VMS
A centralized VMS routes all video streams to a central server for processing, recording, and storage, with clients accessing footage from that server.
Question 2: In a VMS, what is the primary function of a 'failover server'?
- Increase camera resolution during peak hours
- Take over recording duties if the primary server fails (Correct answer)
- Compress video to reduce bandwidth usage
- Provide remote access for mobile clients
Correct answer: Take over recording duties if the primary server fails
A failover server monitors the primary recording server and automatically assumes its recording functions if the primary server becomes unavailable, ensuring continuity.
Question 3: What does ONVIF Profile S specifically define for IP video systems?
- Access control device interoperability
- Video analytics metadata exchange
- Streaming and configuration of IP cameras and video encoders (Correct answer)
- Storage and retrieval of recorded video
Correct answer: Streaming and configuration of IP cameras and video encoders
ONVIF Profile S defines requirements for streaming, configuration, and control of IP cameras and video encoders, enabling interoperability between different manufacturers' devices.
Question 4: Which VMS feature allows operators to define rules that trigger alerts or recording changes when specific conditions are met in video feeds?
- Bandwidth throttling
- Event-based rules engine (Correct answer)
- Codec transcoding
- Frame rate scheduling
Correct answer: Event-based rules engine
An event-based rules engine in a VMS allows administrators to configure automated responses — such as sending alerts or changing recording modes — when defined conditions are detected.
Question 5: What is the purpose of a VMS 'bookmark' feature during video playback?
- Permanently delete footage from a specific timestamp
- Mark specific moments in recorded video for quick future retrieval (Correct answer)
- Increase playback speed for lengthy recordings
- Encrypt a segment of video for secure sharing
Correct answer: Mark specific moments in recorded video for quick future retrieval
Bookmarks allow operators or investigators to tag specific timestamps in recorded video so those moments can be quickly located and reviewed later.
Question 6: In VMS licensing, what is typically meant by a 'channel license'?
- A license to access the VMS client software on one workstation
- A license that authorizes one camera or video input to be managed by the VMS (Correct answer)
- A license for unlimited storage on the VMS server
- A license enabling integration with a third-party access control system
Correct answer: A license that authorizes one camera or video input to be managed by the VMS
A channel license grants the VMS the right to manage a single camera or video source, and adding cameras typically requires purchasing additional channel licenses.
Question 7: Which VMS deployment model allows cameras to store and manage video locally while also syncing metadata and alerts to a central server?
- Pure cloud VMS
- Centralized on-premises VMS
- Hybrid VMS (Correct answer)
- Peer-to-peer VMS
Correct answer: Hybrid VMS
A hybrid VMS combines local edge recording with centralized management, allowing cameras or NVRs to record locally while reporting metadata, alerts, and status to a central management server.
