Axis ANVE cheat sheet

Resolution is pixel count (width x height); 1080p = 1920x1080 = ~2.07 MP; 4K UHD = 3840x2160 = ~8.3 MP.

Pixels per meter (PPM) at the object plane determines identification: ~250 PPM for identification, ~125 PPM for recognition, ~62 PPM for detection (DORI model).

H.264 and H.265 are block-based codecs; H.265/HEVC typically cuts bandwidth ~40-50% vs H.264 at equal quality.

MJPEG sends each frame as a full JPEG, so bitrate scales linearly with frame rate; H.264/H.265 use inter-frame prediction and scale sub-linearly.

Zipstream and similar smart-streaming methods drop detail in non-interest regions while preserving forensic detail in the region of interest.

WDR (wide dynamic range) combines multiple exposures to keep both bright and dark areas usable; it is distinct from simple brightness/contrast gain.

PoE (802.3af) delivers up to ~15.4 W at the source; PoE+ (802.3at) up to ~30 W; PoE++ (802.3bt) up to ~60 W or ~90 W.

IR illumination wavelength (~850 nm vs ~940 nm) trades visible red glow for reduced effective range and lower covert visibility.

VMS architecture choices: centralized recording server vs edge (camera/SD-card) recording vs distributed/hybrid; edge recording preserves video during network loss.

Bandwidth budget per camera = bitrate (Mbps) x 3600 s / 8; storage per camera per day = bitrate (Mbps) x 10.8 GB approx at 1 Mbps continuous.

RAID levels: RAID 1 mirrors, RAID 5 stripes with single parity, RAID 6 double parity; RAID is redundancy, not a backup.

Retention days drive disk sizing: total storage = number of cameras x GB/day/camera x retention days, plus ~10-20% headroom.

Multicast sends one stream to many receivers via IGMP; unicast replicates streams per viewer; multicast requires IGMP snooping on switches.

ONVIF Profile S covers streaming, Profile G edge storage, Profile T advanced streaming/H.265, Profile M metadata/analytics.

Cybersecurity baseline: change default credentials, disable unused services, use HTTPS/TLS, keep firmware current, segment camera VLANs.

Failover and redundancy: redundant recording servers, dual NICs, UPS on cameras and switches, and documented RTO/RPO for video loss.

Axis camera families: M-series (compact/indoor), P-series (indoor/outdoor general), Q-series (high-end/premium), F-series (fixed focal), plus specialty lines.

Axis ARTPEC is the in-house system-on-chip used across many cameras; newer generations add H.265 and deep-learning analytics support.

AXIS Camera Station is the Axis VMS; AXIS Device Manager handles bulk configuration, firmware, and credential management.

Axis Zipstream is the bandwidth/storage-saving compression technology; Axis Lightfinder improves low-light color performance.

Axis OptimizedIR and Forensic WDR are Axis-branded IR and wide dynamic range features; Axis Radar and Axis Loitering Guard are analytics.

Axis AOA (AXIS OS) is the camera operating system; AXIS OS hardening guide and AXIS Device Manager are core admin tools.

Axis access control (A-series) and intercom (I-series) integrate with cameras and VMS for unified surveillance and entry.

Axis product naming: model number plus lens/format suffix and generation; check the datasheet for exact resolution, lens, and PoE class.

Apply least privilege: separate admin, operator, and viewer roles; use unique credentials per device; disable default accounts.

Keep firmware current and stage updates in a test group before fleet-wide rollout; document versions and rollback plan.

Design for coverage: use DORI PPM targets, avoid direct backlight, mount at proper height, and test at the object plane.

Segment the camera network on its own VLAN; restrict inbound/outbound traffic; use HTTPS, 802.1X, and signed certificates.

Document as-built: IP plan, camera schedule, retention, credentials vault, and network topology; label cables and ports.

Validate recording and retention with periodic playback tests and storage-capacity checks; verify failover and UPS behavior.

Use time sync (NTP) across all devices so timestamps align across cameras and VMS for forensic use.

Plan for growth: reserve PoE budget, switch ports, IP ranges, and storage headroom; monitor bandwidth and disk health continuously.
