About the ACTi B23
The ACTi B23 is a rugged outdoor-grade bullet form factor designed to withstand exposure to weather, vandalism, and direct sunlight. 4MP sits in the sweet spot for installations where storage is a concern but you still want crisper retroactive zooming during incident review. There is no built-in IR illuminator on this model, so it depends entirely on ambient light. In dark environments, pair it with external IR floods or white-light illuminators. A narrow field of view trades coverage area for pixel density at distance, the right choice when you need to read faces or plates far from the camera, e.g., long corridors, gate approaches, ANPR installations.
Best use cases for this camera
Long corridor & aisle monitoring
The 49.6° narrow angle is intentionally tuned for corridor work: it concentrates pixel density along the length of the hallway rather than wasting resolution on the side walls. Mount at the far end facing along the corridor.
License plate / ANPR
The combination of 49.6° narrow angle and 3.1MP (2048×1536) resolution provides the pixel density required for ANPR at typical lane widths, especially when paired with proper lane lighting and perpendicular mounting.
Strengths
Considerations
- •No built-in IR, so it needs external illumination for night use
- •Narrow angle requires more cameras to cover wide areas; plan camera count accordingly
Coverage at Different Distances
| Distance | Coverage Width | Coverage Area | Use Case |
|---|---|---|---|
| 5m | 4.6m | 23 m² | Entrance, corridor |
| 10m | 9.2m | 92 m² | Room, retail aisle |
| 15m | 13.9m | 208 m² | Warehouse, parking row |
| 20m | 18.5m | 370 m² | Parking row, courtyard |
| 30m | 27.7m | 832 m² | Parking lot, yard |
| 50m | 46.2m | 2310 m² | Perimeter, large area |
Field of View Visualization
Night Vision Performance
Daytime
Full 3.1MP (2048×1536) resolution at 49.6° field of view. Effective identification range up to 10m in good lighting conditions.
Nighttime (IR)
No built-in IR: at night it needs ambient light or an external illuminator. Switches to B/W mode for clear night footage.
Installation tips for the B23
Plan cabling for multiple cameras to cover wide areas: at 49.6° you cover roughly 9 m of width per camera at 10 m distance.
Coverage geometry & DORI distances
At a 5-metre standoff the ACTi B23 covers about 4.6 m of scene width; at 10 m that grows to 9.2 m, and at 20 m to 18.5 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 89 m, observe up to 35 m, recognise up to 18 m, and produce Identify-level detail (250 px/m in the EN 62676-4 DORI scale) up to 9 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic; the geometry above assumes the 4.9-49mm lens declared by the manufacturer.
Power & cabling
The ACTi B23 draws an estimated 5.5 W under typical load (with the IR illuminator engaged where applicable), placing it in the 802.3af (Class 3, ≤15.4 W) budget. A single switch port supplies enough power without an injector. Cabling: stick to Cat6 STP for runs up to 100 m end-to-end; beyond that, add an inline PoE extender or move to fibre with a media converter at the camera end. On outdoor runs, route through ø25 PVC or PE conduit to keep the cable shielded from UV and rodents.
Privacy & legal (GDPR / RODO)
Any camera operating in a publicly accessible area falls under GDPR (RODO in Poland). Art. 13 obliges the data controller to post an information sign at every entry point with controller name, DPO contact, lawful basis (typically Art. 6(1)(f) legitimate interest for property protection), purpose, and retention period. Even a narrowly-aimed bullet camera can incidentally record passers-by, so the Art. 13 sign at the entry point applies regardless of how tightly the lens is framed.
Installer time & cost (rough estimate)
A typical EU installer quotes 3-4 h of labour per bullet camera of this class (approximately €135-€185 excluding hardware), broken down as bracket mounting, cable termination at both ends, on-site commissioning, and a brief operator handover. Allow extra time for high mounts (>4 m), exterior installations requiring scaffolding, or sites where cable routing demands wall penetrations or conduit work.
Indicative EU pricing at 2024-2025 rates; actual quotes vary by region, mounting height, and site conditions. Excludes hardware, transport, permits, and VAT.
Frequently asked questions
Is the ACTi B23 suitable for outdoor installation?
Yes for the IP66/IP67-rated variant of this model. Bullet and dome bodies in the ACTi range survive direct rain, snow and UV; check the IP / IK rating against your environment (IP66 for rain/dust, IK10 for vandal-prone locations).
What PoE class powers the ACTi B23?
The camera draws roughly 5.5 W in steady-state operation, requiring an 802.3af (Class 3, ≤15.4 W) switch port. A single Cat6 STP cable carries both data and power up to 100 m; beyond that, add an inline extender or convert to fibre near the camera.
How much storage does the ACTi B23 consume per day?
At 3.1MP (2048×1536) resolution, 15 fps H.265 continuous recording, the B23 produces approximately 12 GB per day, about 360 GB per month. Motion-only or event-triggered recording typically cuts that by 40-70 % depending on scene activity. Plan NVR HDD capacity for the longest retention period required by your privacy policy or insurance contract.
Up to what distance can the ACTi B23 identify a person?
By the DORI thresholds of EN 62676-4 (Identify at 250 px/m on the target, a density the 2025 edition calls Characterise), this camera reaches Identify level up to about 9 m, recognises a person up to 18 m, observes general activity up to 35 m, and detects motion up to 89 m. Identification distance assumes daylight or full IR illumination on the target; at the limits of the IR cone the effective identify distance shrinks roughly 30 %.
What network bandwidth does ACTi B23 use?
Typical ingest is 5 Mbps for the main stream (H.265, medium scene complexity, 15 fps) plus ~0.5 Mbps for a low-resolution sub-stream used by mobile clients. For a 16-camera installation of this class, plan a 50-100 Mbps NVR uplink and a dedicated VLAN for camera traffic.
