ACTi B412 vs Geovision BL320-D02U: Specification Comparison
Both the ACTi B412 and Geovision BL320-D02U are 3MP outdoor bullet IP cameras designed for perimeter and open-area surveillance, placing them in the same resolution class and form-factor category. This comparison is aimed at installers and IT buyers evaluating a fixed outdoor bullet for deployments where PoE infrastructure is already in place. The analysis covers imaging performance, installation suitability, and VMS/analytics integration, drawing exclusively from published specifications for each model.

How do the imaging specs compare?
The ACTi B412 uses a 1/2.8-inch sensor delivering 3MP (2048×1536 native) at up to 30 fps, paired with a motorized 4.7–47mm varifocal lens providing 10× optical zoom. Its minimum illumination is rated at 0.003 lux in color mode (F1.6) and 0 lux with IR active. The camera supports 145dB Extreme WDR and employs 940nm invisible IR LEDs with a stated range of 60m. The Geovision BL320-D02U is also rated at 3MP; however, its published specifications do not disclose sensor size, lens focal length, minimum illumination figure, WDR capability, or IR range, making a direct imaging comparison on those parameters impossible.
On compression, the B412 supports H.265, H.264 (Baseline/Main/High), and MJPEG, giving downstream NVR and storage systems flexibility in codec selection and bandwidth management. The BL320-D02U specification lists H.264 only; H.265 support is not documented. For buyers with mixed lighting, high-contrast scenes, or long-range identification requirements, the B412's published numbers—145dB WDR, 60m IR, 10× optical zoom, and 0.003 lux color sensitivity—represent a significantly richer imaging specification than what is documented for the BL320-D02U.
What about installation and environment?
Both cameras carry an IP66 ingress-protection rating, confirming resistance to dust ingress and high-pressure water jets, and both use standard RJ-45 PoE connectivity. The B412 adds an IK10 impact-resistance rating—the highest standard IEC 62262 classification—which the BL320-D02U specification does not list. The B412's operating temperature range is documented at −40°C to 60°C (−40°F to 140°F), covering extreme cold and heat; no operating temperature range is published for the BL320-D02U.
Power input for the B412 is listed as both DC 12V and PoE++ (IEEE 802.3bt), with a note of 'High PoE (IEEE 802.3at)' also appearing in the spec set—buyers should confirm the actual power draw with ACTi to ensure switch compatibility. The BL320-D02U is listed simply as 'PoE' with no 802.3 class specified. Mounting options for the B412 include wall, ceiling, pole, and rack; the BL320-D02U specification documents wall mount only.
Which fits your VMS and analytics better?
The ACTi B412 declares ONVIF conformance across Profiles S, G, T, and M, covering live streaming, on-board recording, metadata/analytics streaming, and device management respectively. PTZ control is documented via Visca, Pelco-D, Pelco-P, and ACTi URL commands. Edge analytics listed include VMD (video motion detection), People Counting, and Smoke Detection. Audio capabilities include a built-in microphone, mic-in, line-in, and line-out. On-board storage is not explicitly stated in the provided specifications.
The Geovision BL320-D02U states ONVIF compliance but does not specify which ONVIF Profiles are supported. Two-way audio is listed, though input/output connector details are not provided. No edge analytics are documented for the BL320-D02U. On-board storage is not mentioned in its specification set. For installations requiring analytics at the edge, multi-profile ONVIF, or PTZ control protocol flexibility, the B412's documented feature set is substantially more detailed than the BL320-D02U's published specifications allow buyers to evaluate.
Which should you choose: the B412 or the BL320-D02U?
Our take: The B412 is the stronger choice when documented imaging performance, environmental resilience, and edge intelligence are the primary evaluation criteria. Three concrete spec deltas illustrate the gap: first, the B412 publishes a 145dB WDR rating and a 0.003 lux color minimum illumination against a 60m 940nm IR range, while the BL320-D02U discloses none of those figures; second, the B412 carries an IK10 impact rating and a −40°C to 60°C operating envelope versus no IK rating and no temperature range on the BL320-D02U; third, the B412 declares ONVIF Profiles S, G, T, and M plus VMD, People Counting, and Smoke Detection analytics, while the BL320-D02U lists ONVIF compliance without profile specifics and no analytics. If the BL320-D02U has competitive specs in these areas, they are absent from the published datasheet. Choose the BL320-D02U only after confirming those specifications directly with Geovision and verifying VMS profile compatibility for your platform.

Frequently Asked Questions
Which should you choose: the B412 or the BL320-D02U?
The B412 is the stronger choice when documented imaging performance, environmental resilience, and edge intelligence are the primary evaluation criteria. Three concrete spec deltas illustrate the gap: first, the B412 publishes a 145dB WDR rating and a 0.003 lux color minimum illumination against a 60m 940nm IR range, while the BL320-D02U discloses none of those figures; second, the B412 carries an IK10 impact rating and a −40°C to 60°C operating envelope versus no IK rating and no temperature range on the BL320-D02U; third, the B412 declares ONVIF Profiles S, G, T, and M plus VMD, People Counting, and Smoke Detection analytics, while the BL320-D02U lists ONVIF compliance without profile specifics and no analytics. If the BL320-D02U has competitive specs in these areas, they are absent from the published datasheet. Choose the BL320-D02U only after confirming those specifications directly with Geovision and verifying VMS profile compatibility for your platform.
Is the B412 or BL320-D02U better for low-light performance?
Based on published specifications, only the ACTi B412 documents low-light figures: 0.003 lux in color mode at F1.6 and 0 lux with its 940nm IR LEDs active at a 60m range. The Geovision BL320-D02U does not publish a minimum illumination value or IR range in its available specifications, so a data-driven low-light comparison cannot be made for that model. Confirm BL320-D02U low-light specs directly with Geovision before selecting for night-time or poorly lit deployments.
Will either camera work with my existing 802.3af PoE switch?
The ACTi B412 specification references both PoE++ (802.3bt) and 'High PoE (IEEE 802.3at)'; buyers should verify the camera's actual power draw with ACTi to confirm whether a standard 802.3af (15.4W) port is sufficient or whether an 802.3at (30W) or 802.3bt (60–90W) port is required. The Geovision BL320-D02U is listed only as 'PoE' with no 802.3 class specified, so its switch requirements should also be confirmed with Geovision before purchase.
Do both cameras support analytics like motion detection or people counting?
The ACTi B412 documents VMD (video motion detection), People Counting, and Smoke Detection as on-board edge analytics. The Geovision BL320-D02U's published specifications list no edge analytics capabilities. If analytics at the edge are required for your deployment, only the B412 has documented support; the BL320-D02U would require verification with Geovision or reliance on server-side VMS analytics.
