A VMS is configured to record in 'continuous + event' mode. What does this mean?
Answer: It records continuously at low frame rate and switches to high frame rate during events
Continuous + event mode records a baseline stream at reduced frame rate or quality at all times and triggers a higher-quality recording stream when an event or alarm occurs.
Which VMS feature provides a chronological visual summary of all recorded activity periods for a camera, typically shown as a color-coded bar?
Answer: Timeline scrubber
The timeline scrubber displays recording periods as a color-coded bar, allowing operators to visually identify recorded segments and quickly navigate to specific times.
What risk does running a VMS on a shared general-purpose server (alongside other business applications) introduce?
Answer: Resource contention that can cause dropped frames or recording gaps
Sharing server resources with other applications can cause CPU, RAM, or disk I/O contention, degrading VMS performance and potentially causing frame drops or missed recordings.
In a federated VMS architecture, what is the role of the 'central management server'?
Answer: It provides unified access and management across multiple independent VMS installations
A central management server in a federated architecture provides a single pane of glass for operators to view, manage, and search video across geographically distributed VMS sites.
Which encryption standard is most commonly recommended for protecting stored video files on a VMS server?
Answer: AES-256
AES-256 (Advanced Encryption Standard with 256-bit keys) is the industry-standard symmetric encryption algorithm recommended for protecting stored video data at rest.
What does 'video dewarping' refer to in a VMS that supports fisheye cameras?
Answer: Software correction that transforms a 360° fisheye image into a flat, navigable perspective view
Video dewarping is a software process that mathematically corrects the radial distortion of a fisheye lens, converting the circular image into a usable flat or panoramic view.
A technician needs to verify that a VMS is recording at the configured frame rate. Which tool within the VMS is most useful for this verification?
Answer: Camera statistics or diagnostic panel showing actual received FPS
The camera statistics or diagnostics panel displays real-time metrics including actual frames per second being received and recorded, confirming whether the configured rate is being achieved.
