Axis ANVE flashcards
Axis ANVE · Build recall with a focused review session.
32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- DORI
- Detection, Observation, Recognition, Identification: a coverage standard that maps pixels per meter at the object plane to a required level of visual detail.
- Pixels per meter
- The number of image pixels that cover one meter of the scene at the object plane; higher PPM yields more detail and better identification.
- H.265/HEVC
- A block-based video codec that typically reduces bandwidth and storage 40 to 50 percent versus H.264 at comparable image quality.
- MJPEG
- A codec that compresses every frame as an independent JPEG, so bitrate rises almost linearly with frame rate and resolution.
- Wide dynamic range
- A camera capability that combines multiple exposures so both bright and dark regions of a high-contrast scene remain visible.
- PoE 802.3af
- The original Power over Ethernet standard, delivering roughly 15.4 watts at the power source over a single Ethernet cable.
- PoE+ 802.3at
- An updated Power over Ethernet standard that delivers roughly 30 watts at the source, supporting cameras with heaters or IR.
- IR illumination
- Infrared light near 850 or 940 nanometers that lets a camera see in darkness without visible white light to the human eye.
- Zipstream
- A smart-streaming compression method that reduces bitrate by discarding detail in unimportant areas while preserving forensic detail in the region of interest.
- Multicast streaming
- A method that sends one video stream to many receivers at once; it requires IGMP snooping on switches to avoid flooding.
- ONVIF Profile S
- An interoperability profile covering basic video streaming and device discovery between cameras and management software from different vendors.
- RAID 5
- A disk configuration that stripes data with single parity, surviving one drive failure but not serving as a substitute for backup.
- Retention period
- The number of days recorded video is kept before overwrite; it drives total storage sizing along with camera count and bitrate.
- Edge recording
- Storing video on an SD card inside the camera so footage survives network outages or recording server failures.
- Storage per camera per day
- Approximate daily storage equals bitrate in Mbps multiplied by about 10.8 gigabytes for continuous recording.
- VMS
- Video management software that connects cameras, records streams, manages users, and provides playback and export of footage.
- Camera VLAN segmentation
- Placing cameras on a separate virtual LAN so surveillance traffic is isolated from business systems and access can be restricted.
- Failover recording server
- A secondary server that takes over recording if the primary fails, reducing video loss during hardware or software outages.
- ARTPEC
- Axis in-house system-on-chip family used in many cameras, adding support for newer codecs and on-camera analytics.
- AXIS Camera Station
- Axis video management software for recording, viewing, and managing Axis cameras and compatible third-party devices.
- AXIS Device Manager
- A tool for discovering, configuring, updating firmware, and managing credentials across many Axis devices at once.
- Lightfinder
- An Axis technology that improves color image quality in very low light, reducing the need for infrared illumination.
- OptimizedIR
- An Axis infrared illumination feature that adjusts IR output to the scene and lens to avoid overexposure and hotspots.
- Forensic WDR
- An Axis wide dynamic range feature that preserves detail in both bright and dark areas for evidentiary image quality.
- AXIS OS
- The operating system running on Axis network cameras and devices, providing the web interface, security, and feature set.
- Axis M-series
- A line of compact, cost-effective Axis cameras suited to indoor and space-constrained installations.
- Axis Q-series
- A premium Axis camera line offering high resolution, advanced analytics, and features for demanding installations.
- Least privilege
- Granting each user only the access needed for their role, with separate admin, operator, and viewer accounts.
- Firmware staging
- Testing updates on a small group of devices before fleet-wide rollout, with a documented rollback plan.
- NTP time sync
- Synchronizing clocks across cameras and servers so timestamps align, which is essential for forensic review and evidence.
- As-built documentation
- Records of the installed system, including IP plan, camera schedule, retention settings, topology, and labeled cabling.
- Playback verification
- Periodically confirming that recordings exist, play back correctly, and match the intended retention period.
