ACTi A88 vs Geovision VD321-D01U: Specification Comparison
Both the ACTi A88 and Geovision VD321-D01U are 3MP outdoor vandal-resistant IP dome cameras targeting perimeter and general surveillance deployments. This comparison examines how they stack up across imaging performance, physical installation requirements, and VMS/analytics integration—key decision points for installers and IT buyers evaluating fixed dome cameras in the same resolution class and form factor.

How do the imaging specs compare?
The ACTi A88 ships with a 1/2.8" sensor, a 2.85x optical zoom lens covering 2.8–8.0 mm, and a minimum illumination of 0.003 lux in color mode (0 lux in B/W with IR active). Its IR illuminators reach 30 m, and it supports Advanced WDR rated at 120 dB—a concrete figure that matters in scenes with mixed lighting such as building entrances or loading docks. Maximum frame rate is 30 fps across 2048×1536, 1920×1080, and 1280×720 resolutions.
The Geovision VD321-D01U is also specified at 3MP resolution with built-in IR, but its published specifications do not disclose sensor size, lens focal length, minimum illumination value, IR range distance, WDR capability or rating, or maximum frame rate. Buyers who require those figures for site design or NVR configuration will need to obtain them directly from Geovision's datasheet before making a final selection.
What about installation and environment?
Both cameras carry IP66 ingress protection and IK10 impact resistance, making them suitable for outdoor and vandal-prone environments. The Geovision spec sheet also lists an IK10+ designation in the Certifications field, though no numeric upgrade beyond IK10 is defined in the IEC 62262 standard—buyers should verify the exact test condition with Geovision. The A88 is rated for –20°C to 50°C (–4°F to 122°F); no operating temperature range is published for the VD321-D01U.
Power delivery on the A88 is specified as PoE IEEE 802.3af Class 3 or DC 12V, connecting via an RJ-45 pigtail. The camera weighs 363 g (0.8 lb) and supports wall, pole, pendant, and corner mounting. The VD321-D01U is confirmed PoE-powered and supports ceiling and wall mounting; PoE class, supply voltage options, connector type, and weight are not disclosed in the provided specifications.
Which fits your VMS and analytics better?
The ACTi A88 is ONVIF-compliant at Profile S, G, T, and Q—the broadest standard profile set, covering live streaming, recording, metadata, and discovery. It also includes on-board edge analytics: Video Motion Detection (VMD) and People Counting are listed in the specification. No audio specification or on-board storage (SD card) details are provided for the A88.
The Geovision VD321-D01U lists ONVIF compliance without specifying which profiles are supported, which matters for VMS integrators who depend on Profile G for edge recording or Profile T for H.265 metadata. No edge analytics, audio input/output, or on-board storage details are present in the provided specifications. Buyers integrating into Geovision's own GV-VMS platform should confirm native driver support separately.
Which should you choose: the A88 or the VD321-D01U?
Our take: The A88 is the stronger choice when imaging transparency and VMS breadth are required—but the VD321-D01U cannot be ruled out without a complete datasheet. Spec-to-spec, the A88 provides three concrete advantages: a published 120 dB Advanced WDR rating versus no WDR data for the VD321-D01U; a disclosed 0.003 lux color minimum illumination and 30 m IR range versus no equivalent figures for the Geovision; and ONVIF Profile S/G/T/Q compliance versus an unspecified ONVIF level. The A88 also adds People Counting and VMD analytics at the edge, which the VD321-D01U does not document. The A88's 2.85x optical zoom adds scene flexibility the fixed-lens (assumed) VD321-D01U cannot match. Choose the VD321-D01U only after Geovision confirms the missing specs meet your site requirements, or where an existing Geovision VMS ecosystem makes native integration the priority.

Frequently Asked Questions
Which should you choose: the A88 or the VD321-D01U?
The A88 is the stronger choice when imaging transparency and VMS breadth are required—but the VD321-D01U cannot be ruled out without a complete datasheet. Spec-to-spec, the A88 provides three concrete advantages: a published 120 dB Advanced WDR rating versus no WDR data for the VD321-D01U; a disclosed 0.003 lux color minimum illumination and 30 m IR range versus no equivalent figures for the Geovision; and ONVIF Profile S/G/T/Q compliance versus an unspecified ONVIF level. The A88 also adds People Counting and VMD analytics at the edge, which the VD321-D01U does not document. The A88's 2.85x optical zoom adds scene flexibility the fixed-lens (assumed) VD321-D01U cannot match. Choose the VD321-D01U only after Geovision confirms the missing specs meet your site requirements, or where an existing Geovision VMS ecosystem makes native integration the priority.
Is the A88 or VD321-D01U better for low-light performance?
Based on published specifications, the ACTi A88 has a documented minimum illumination of 0.003 lux in color mode and 0 lux in B/W with IR active, with an IR range of 30 m. The Geovision VD321-D01U lists built-in IR but provides no minimum illumination figure or IR distance in its published specs, so a direct low-light comparison cannot be made from available data alone.
Can both cameras work with third-party VMS platforms like Milestone or Genetec?
The ACTi A88 supports ONVIF Profile S, G, T, and Q, which are the profiles most commonly required by third-party VMS platforms for full feature integration. The Geovision VD321-D01U lists ONVIF compliance but does not specify which profiles are supported—confirm with Geovision or your VMS vendor before assuming full feature parity.
Do both cameras support outdoor installation without an additional housing?
Yes, both carry IP66 weatherproofing and IK10 vandal resistance as published specs, qualifying them for unprotected outdoor mounting. The ACTi A88 additionally specifies an operating temperature range of –20°C to 50°C. No operating temperature range is published for the Geovision VD321-D01U, so installers in extreme-temperature environments should verify that spec directly with Geovision.
