i-PRO X86531-Z2 vs i-PRO X86531-Z2-1: Specification Comparison
Both the i-PRO WV-X86531-Z2 and WV-X86531-Z2-1 are 22MP outdoor AI PTZ dome cameras sharing the same SKU family. They target the same market segment: wide-area surveillance requiring long-range PTZ coverage, edge AI analytics, and harsh-environment resilience. The comparison below focuses on documented specification differences—primarily in AI analytics scope, housing finish, alarm action capabilities, and a few imaging parameter details—to help installers and IT buyers determine which variant better suits a specific deployment.

How do the imaging specs compare?
Both models use the same quad 1/2.7-inch CMOS plus one 1/2.8-inch CMOS sensor array, sharing identical scanning area (5.12 × 3.84 mm H×V), 144 dB maximum dynamic range (Super Dynamic adjustable 0–31), adaptive black stretch (0–255), maximum AGC gain (0–11), DNR (0–255), and the same 21x motorized optical zoom with a 4.0–84.6 mm focal length covering 3.7°–77° horizontal field of view. Minimum illumination is specified at 0.006 lux B&W (F1.6) for both; Product A lists this at an implied 1/30s shutter condition while Product B explicitly states 1/30s. Product A's datasheet card references 0.011 lux color; Product B's datasheet card also lists 0.011 lux color—both are consistent.
The shutter range is expressed differently: Product A states a maximum shutter of 1/10000s (15 fps mode), while Product B states 1/10000s to 16/30s, providing a more complete range. Identification range at tele is 118.9 m / 390 ft for Product A and 118.9 m for Product B—identical. Observe range differs in the provided specs: Product A lists 18.1 m / 59.4 ft while Product B lists 475.5 m / 1,560.2 ft; this discrepancy appears to be a documentation variant rather than a physical difference, and buyers should verify against the respective official datasheets. Frame rate, resolution options (3072×2304 down to QVGA), and extra digital zoom (4.0×–31×) are identical across both models.
What about installation and environment?
Both cameras share identical environmental and mechanical ratings: IP67/IP66 (IEC 60529), Type 4X (UL50E), NEMA 4X compliant, IK10 impact resistance (IEC 62262), and wind resistance up to 40 m/s (~89 mph). Operating temperature is –40°C to +55°C with 10–100% humidity (non-condensing) and Temish anti-condensation element on both. Dimensions (ø250 mm × 195 mm H) and weight (approximately 3.8 kg) are identical.
Power input is PoE++ (IEEE 802.3bt) at 35.6 W for both—PoE Class 5. Both use dual RJ45 connectors supporting 10/100/1000 BASE-T. The primary physical distinction is the housing finish: Product A (Z2) is specified as aluminum die cast and stainless steel, while Product B (Z2-1) adds PC resin to that material list and is described as black finish versus the Z2's unspecified (white per the color field) finish. Both share identical PTZ mechanics: 360° endless pan, –15° to +195° tilt, 256 preset positions, and pan/tilt speeds up to 500°/s preset.
Which fits your VMS and analytics better?
Both models support ONVIF Profiles G, M, S, and T; H.265/H.264 (CBR/VBR) and MJPEG compression with Smart Coding (GOP control, Smart VIQS, Smart P-picture); up to 24 simultaneous users; IPv6 protocol suite including MQTT, SNMPv1/v2/v3, 802.1X, and FIPS 140-2 Level 3 security. Edge storage supports microSD/microSDHC/microSDXC up to 512 GB on both. Mobile compatibility (iOS 8.0+, Android) and browser support (Edge, Firefox, Chrome) are identical.
The most substantive integration difference is in AI analytics scope. Product A (Z2) specifies AI Video Motion Detection, Face Detection, and People Detection. Product B (Z2-1) specifies AI Video Motion Detection, Face Detection, and Vehicle Detection—replacing People Detection with Vehicle Detection as a named class. Both support identical AI sound classification (gunshot, yell, vehicle horn, glass break) and VMD (4 areas), SCD (1 area), and audio detection. Alarm actions differ: Product A lists email, HTTP, and TCP notifications plus SD recording; Product B lists email, HTTP, and TCP notifications only—SD recording as an alarm action is not listed in Product B's spec. Audio input impedance is specified as 2 kΩ for Product A; Product B specifies –51 to –38 dB sensitivity instead. GUI language support is listed as 9 named languages for Product A and '9 languages' (unnamed) for Product B.
Which should you choose: the X86531-Z2 or the X86531-Z2-1?
Our take: The WV-X86531-Z2 is the stronger choice when People Detection and alarm-triggered SD recording are required workflow elements. The Z2 explicitly names People Detection among its AI analytics classes and lists SD card recording as an alarm action—neither appears in the Z2-1's provided specifications. Conversely, the WV-X86531-Z2-1 explicitly includes Vehicle Detection as a named AI class and adds PC resin to its housing materials with a black finish, which may suit certain aesthetic or thermal requirements. Core imaging performance is effectively identical: both deliver 144 dB dynamic range, 0.006 lux B&W minimum illumination, 21x optical zoom, dual PoE++ at 35.6 W, IP67/IP66/IK10 ratings, and –40°C to +55°C operation. Buyers integrating with a VMS that relies on people-counting or occupancy workflows should confirm analytics API support with their VMS vendor before selecting the Z2-1, as People Detection is not listed in its provided spec.

Frequently Asked Questions
Which should you choose: the X86531-Z2 or the X86531-Z2-1?
The WV-X86531-Z2 is the stronger choice when People Detection and alarm-triggered SD recording are required workflow elements. The Z2 explicitly names People Detection among its AI analytics classes and lists SD card recording as an alarm action—neither appears in the Z2-1's provided specifications. Conversely, the WV-X86531-Z2-1 explicitly includes Vehicle Detection as a named AI class and adds PC resin to its housing materials with a black finish, which may suit certain aesthetic or thermal requirements. Core imaging performance is effectively identical: both deliver 144 dB dynamic range, 0.006 lux B&W minimum illumination, 21x optical zoom, dual PoE++ at 35.6 W, IP67/IP66/IK10 ratings, and –40°C to +55°C operation. Buyers integrating with a VMS that relies on people-counting or occupancy workflows should confirm analytics API support with their VMS vendor before selecting the Z2-1, as People Detection is not listed in its provided spec.
Is the WV-X86531-Z2 or WV-X86531-Z2-1 better for low-light performance?
Based on the provided specifications, both cameras are rated identically for low-light: 0.006 lux B&W at F1.6 and 0.011 lux color. Neither model has a specified IR illuminator range (both list IR LED as '—'). Low-light performance is not a differentiator between these two models per the available specs.
Can the WV-X86531-Z2-1 record to an SD card on alarm trigger?
Per the provided specifications, the Z2-1's alarm actions are listed as email, HTTP, and TCP notifications only—SD card recording as an alarm action is not listed. The Z2 explicitly includes SD recording as an alarm action. Buyers who require alarm-triggered local recording should select the Z2 or verify the Z2-1's full firmware capabilities directly with i-PRO.
What is the physical difference between the WV-X86531-Z2 and WV-X86531-Z2-1?
The primary specified physical difference is the housing finish and materials. The Z2 is listed as aluminum die cast and stainless steel (housing color: white per spec). The Z2-1 adds PC resin to the material list and is described as aluminum die cast (black), stainless steel, and PC resin. Dimensions, weight, IP/IK ratings, and PTZ mechanics are identical between the two models.
