About the ACTi A24
The ACTi A24 is a rugged outdoor-grade bullet form factor designed to withstand exposure to weather, vandalism, and direct sunlight. At 5-to-6MP the sensor sits between 1080p economy and 4K forensic detail: enough pixels-per-metre for evidence-grade faces at typical entrance and driveway distances, while keeping recording bitrate materially lighter than an 8MP camera. 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 wide 80-120° angle covers a large room or open area from a single mounting position, making it ideal for retail floors, conference rooms, and small parking lots.
Best use cases for this camera
Entrance, lobby & vestibule
The 89.1° field of view captures the entire entrance and surrounding waiting area from a single ceiling mount. Useful for capturing visitors as they enter and leave.
Strengths
- •5MP sensor preserves detail under digital zoom on recorded footage
Considerations
- •No built-in IR, so it needs external illumination for night use

Field of View Visualization
Night Vision Performance
Daytime
Full 5.0MP (2592×1944) resolution at 89.1° field of view. Effective identification range up to 6m 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 A24
Position so the most important subject (entrance, cash register, gate) is in the center third of the frame, because peripheral pixel density drops with wide angles.
Plan storage at roughly 20 GB per camera per day for continuous H.265 recording at 15fps, and verify the NVR has sufficient HDD bay capacity.
Coverage geometry & DORI distances
At a 5-metre standoff the ACTi A24 covers about 9.8 m of scene width; at 10 m that grows to 19.7 m, and at 20 m to 39.4 m. Translating those numbers through EN 62676-4 pixel-density thresholds, the camera can detect a person up to 53 m, observe up to 21 m, recognise up to 11 m, and produce Identify-level detail (250 px/m in the EN 62676-4 DORI scale) up to 5 m. Effective range above the identify threshold relies on supplementary lighting or a longer-focal-length optic; the geometry above assumes the 3.6-10mm lens declared by the manufacturer.
Power & cabling
The ACTi A24 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 A24 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 A24?
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 A24 consume per day?
At 5.0MP (2592×1944) resolution, 15 fps H.265 continuous recording, the A24 produces approximately 20 GB per day, about 600 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 A24 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 5 m, recognises a person up to 11 m, observes general activity up to 21 m, and detects motion up to 53 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 A24 use?
Typical ingest is 8 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.
