Geovision VD321-D01U vs Geovision VD3400-001U: Specification Comparison
The Geovision VD321-D01U and VD3400-001U are both 3MP vandal-proof PoE dome cameras targeting indoor/outdoor fixed-installation surveillance. Both share the same resolution class, dome form factor, IR night vision, ONVIF compatibility, and PoE power delivery. The key differentiators are impact rating, ingress protection level, WDR capability, and lens configuration — factors that meaningfully affect site suitability, image quality under mixed lighting, and field-of-view flexibility. This comparison draws solely from the provided specification data for each model.

How do the imaging specs compare?
Both cameras deliver 3MP resolution and include built-in IR for low-light and nighttime imaging. The VD321-D01U lists IR and Built-in IR as its night-vision mechanism with no further IR range or minimum illumination figures provided in the supplied specs. The VD3400-001U similarly lists IR and Day/Night mode, indicating an ICR (infrared cut filter) mechanism for color-to-monochrome switching, but no minimum illumination value or IR range distance is specified for either model — buyers should consult the individual datasheets for those figures.
The VD3400-001U carries a significant imaging advantage in mixed-lighting environments: it includes WDR Pro (also listed as WDR), which is absent from the VD321-D01U spec set. WDR is critical for scenes with simultaneous bright and dark zones — entryways, parking structures, and window-facing angles. On lens flexibility, the VD3400-001U specifies a 3–9 mm varifocal lens, allowing field-of-view adjustment at installation; the VD321-D01U provides no lens or focal-length specification in the supplied data, so its lens configuration is unknown from these specs alone.
What about installation and environment?
Both cameras are rated IP66 or better for water and dust ingress. The VD321-D01U carries an IP66 rating, protecting against powerful water jets. The VD3400-001U steps up to IP67, adding protection against temporary immersion up to 1 meter — a meaningful difference for ground-level, flood-prone, or washdown-intensive deployments. On impact resistance, the VD321-D01U is explicitly rated IK10 (and listed as IK10+ in certifications), the highest standardized vandal-resistance rating. No IK rating is listed for the VD3400-001U in the provided specs, leaving its impact resistance unquantified from this data.
Both cameras support ceiling and wall mounting in a dome form factor and are powered exclusively via PoE over standard RJ-45 — no auxiliary power input is specified for either. No operating temperature range, PoE class, or physical dimensions are included in the provided specifications for either model; installers should verify thermal ratings from datasheets before deploying in extreme-temperature environments.
Which fits your VMS and analytics better?
Both cameras declare ONVIF compatibility — the VD321-D01U lists 'ONVIF' and the VD3400-001U lists 'ONVIF compatible' — enabling integration with any ONVIF-conformant VMS without proprietary drivers. Neither model lists edge analytics, on-board storage (SD card slot), audio input/output, or alarm I/O in the provided specifications. Buyers requiring these features should consult the full datasheets, as absence from this spec set does not confirm the features are absent from the hardware. No codec, frame rate, or compression format data is provided for either unit in these specs.
Which should you choose: the VD321-D01U or the VD3400-001U?
Our take: The VD321-D01U is the stronger choice when physical security of the camera itself is the primary concern: it carries a confirmed IK10 (IK10+ certified) vandal-resistance rating, while the VD3400-001U provides no IK rating in the supplied specs. Conversely, the VD3400-001U is the better fit for challenging optical environments and versatile coverage zones: it adds WDR Pro (absent on the VD321-D01U), a 3–9 mm varifocal lens for adjustable field of view (versus no lens spec on the VD321-D01U), and a higher IP67 ingress rating versus IP66 on the VD321-D01U. If the install site involves backlit scenes, wide focal-length variability needs, or occasional immersion risk, the VD3400-001U's optical and sealing specs are the differentiators. For high-impact-risk environments where the camera housing itself may face deliberate physical attack, the VD321-D01U's certified IK10 rating is the deciding factor.

Frequently Asked Questions
Which should you choose: the VD321-D01U or the VD3400-001U?
The VD321-D01U is the stronger choice when physical security of the camera itself is the primary concern: it carries a confirmed IK10 (IK10+ certified) vandal-resistance rating, while the VD3400-001U provides no IK rating in the supplied specs. Conversely, the VD3400-001U is the better fit for challenging optical environments and versatile coverage zones: it adds WDR Pro (absent on the VD321-D01U), a 3–9 mm varifocal lens for adjustable field of view (versus no lens spec on the VD321-D01U), and a higher IP67 ingress rating versus IP66 on the VD321-D01U. If the install site involves backlit scenes, wide focal-length variability needs, or occasional immersion risk, the VD3400-001U's optical and sealing specs are the differentiators. For high-impact-risk environments where the camera housing itself may face deliberate physical attack, the VD321-D01U's certified IK10 rating is the deciding factor.
Is the VD321-D01U or VD3400-001U better for low-light performance?
Based on the provided specs, both cameras include built-in IR night vision. The VD3400-001U additionally lists Day/Night mode, indicating an ICR filter for true color-to-monochrome switching, and includes WDR Pro for high-contrast scenes. The VD321-D01U does not list WDR or Day/Night mode in its specs. Neither model provides a minimum illumination figure or IR range distance in the supplied data — consult the individual datasheets for those values before making a final low-light decision.
Which camera is more vandal-resistant?
The VD321-D01U specifies IK10 impact resistance and carries an IK10+ certification — IK10 is the highest standardized rating under IEC 62262, corresponding to 20 joules of impact energy. The VD3400-001U provides no IK rating in the supplied specifications, so its impact resistance level cannot be confirmed from this data. For sites where deliberate physical attack on the camera is a known risk, the VD321-D01U's certified IK10+ rating is the verifiable choice.
Can either camera work with my existing ONVIF-compatible NVR?
Yes — both the VD321-D01U and VD3400-001U declare ONVIF compatibility, which allows integration with any ONVIF-conformant NVR or VMS without proprietary drivers or software. Both also use standard PoE over RJ-45, eliminating the need for separate power runs. Neither model lists proprietary VMS requirements in the provided specs, so either should integrate into a standard ONVIF-based system.
