Hanwha QNP-6250H vs i-PRO S66300-Z3: Specification Comparison
Both the Hanwha QNP-6250H and the i-PRO WV-S66300-Z3 are 2MP outdoor PTZ dome cameras targeting professional IP video surveillance installations. Both deliver 1920×1080 resolution at 60 fps, IK10/IP66 weatherproofing, ONVIF compliance, and PoE power — making them direct cross-shop candidates for perimeter and wide-area monitoring projects where pan-tilt-zoom coverage, edge analytics, and network integration are key purchasing criteria.

How do the imaging specs compare?
Both cameras share a 1/2.8" CMOS sensor and a maximum 60 fps frame rate at 1920×1080. The QNP-6250H offers a 25x optical zoom with a 4.44–111 mm focal length and a maximum aperture of F1.6 (Wide)/F3.9 (Tele), while the WV-S66300-Z3 delivers a 32x optical zoom (extendable to 48x at 1280×720) across a 4.25–136 mm focal length at the same F1.6 (Wide)/F4.4 (Tele) aperture. The i-PRO's longer tele focal length and extra zoom tier give it a materially greater tele detection range: 1,833 m versus 1,471 m at 25 PPM on the DORI scale.
In low-light performance, the QNP-6250H specifies 0.05 lux color and 0.005 lux B/W with Auto ICR day/night switching. The WV-S66300-Z3 lists 0.006 lux as its minimum illumination figure without a separate color/B/W breakdown. WDR is 120 dB on the Hanwha versus a stated maximum of 144 dB (Super Dynamic Level 31) on the i-PRO. The Hanwha includes SSNR V digital noise reduction; the i-PRO offers a 0–255 adjustable DNR scale plus an Adaptive Black Stretch feature with a 0–255 range, adding more tuning granularity. Both include a built-in gyro-based digital image stabilizer and defog/fog compensation.
What about installation and environment?
Both units carry IP66 and IK10 ratings and are certified for outdoor use. The i-PRO WV-S66300-Z3 adds NEMA 4X and NEMA-TS2 certifications and specifies wind resistance up to 40 m/s (~89 mph), neither of which appears in the QNP-6250H spec sheet. Operating temperature ranges differ notably: the QNP-6250H is rated –35°C to +55°C, whereas the WV-S66300-Z3 is rated –50°C to +60°C — a wider envelope on both ends that may matter in extreme-climate deployments.
Power requirements diverge significantly. The QNP-6250H draws up to 23 W and requires PoE+ (IEEE 802.3at, Class 4). The WV-S66300-Z3 draws 37.8 W and requires PoE++ (Class 6), meaning existing PoE+ switches cannot power it without a midspan injector or infrastructure upgrade. The Hanwha body is aluminum (head polycarbonate), weighing 2,700 g at ø204.3×265 mm; the i-PRO is aluminum die-cast with a polycarbonate dome, weighing approximately 3,000 g at ø167×205 mm — more compact in diameter but heavier per unit volume. Both support ceiling, wall, pole, and parapet mounting; the Hanwha publishes specific accessory SKUs (e.g., SBP-156HMW, SBP-156WMW) in its spec sheet, while the i-PRO spec sheet does not list mount accessory part numbers.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile S/G/T compliant. The QNP-6250H additionally lists ONVIF Profile and Wisenet Open Platform SDK support with SUNAPI (HTTP API), and includes the NTCIP 1205 protocol — relevant for traffic and public-safety integrations. The i-PRO adds ONVIF Profile M, which covers metadata and analytics interoperability beyond what Profile S/G/T provide. The i-PRO's SoC is identified as an Ambarella CV25m; no SoC is specified for the Hanwha. On-board analytics depth differs: the WV-S66300-Z3 provides AI-classified video motion detection, face detection, people detection, vehicle detection, non-mask detection, occupancy detection, scene change detection, and AI sound classification (gunshot, yell, vehicle horn, glass break). The QNP-6250H covers directional detection, enter/exit, virtual line, tampering, and motion detection — solid but without named AI object classification.
Audio support is absent on the QNP-6250H (no audio compression listed; alarm output and audio clip play require an optional I/O box SPM-4210). The WV-S66300-Z3 ships with four 3.5 mm stereo audio inputs, one audio output, and supports G.726, G.711, and AAC-LC compression, enabling full duplex audio natively. Edge storage is microSD/SDHC/SDXC up to 256 GB on the Hanwha; microSDXC (capacity ceiling not stated in the provided spec) on the i-PRO. Security posture: the i-PRO cites FIPS 140-2 Level 3 compliance, which may be a requirement in federal or regulated-industry deployments; the Hanwha lists firmware encryption, Digest Authentication, 802.1X (EAP-TLS/LEAP/PEAP), and a pre-installed Hanwha Techwin Root CA device certificate, but does not claim FIPS 140-2.
Which should you choose: the QNP-6250H or the S66300-Z3?
Our take: The WV-S66300-Z3 is the stronger choice when maximum optical reach, advanced AI analytics, native audio, extreme-temperature tolerance, and FIPS 140-2 security compliance are priorities. Its 32x optical zoom (versus 25x) extends tele detection range to 1,833 m versus 1,471 m — a 25% improvement at the DORI detect threshold. Its dynamic range reaches 144 dB versus 120 dB, offering more headroom in high-contrast scenes. Operating temperature spans –50°C to +60°C versus –35°C to +55°C, a meaningful advantage in arctic or high-heat environments. However, the i-PRO demands PoE++ (Class 6, 37.8 W) rather than the QNP-6250H's PoE+ (Class 4, 23 W max), so existing PoE+ infrastructure will require injectors or switch upgrades. The QNP-6250H is the better fit where PoE+ infrastructure is already deployed, Wisenet/NTCIP integration is required, and budget or power-plant constraints favor lower draw.

Frequently Asked Questions
Which should you choose: the QNP-6250H or the S66300-Z3?
The WV-S66300-Z3 is the stronger choice when maximum optical reach, advanced AI analytics, native audio, extreme-temperature tolerance, and FIPS 140-2 security compliance are priorities. Its 32x optical zoom (versus 25x) extends tele detection range to 1,833 m versus 1,471 m — a 25% improvement at the DORI detect threshold. Its dynamic range reaches 144 dB versus 120 dB, offering more headroom in high-contrast scenes. Operating temperature spans –50°C to +60°C versus –35°C to +55°C, a meaningful advantage in arctic or high-heat environments. However, the i-PRO demands PoE++ (Class 6, 37.8 W) rather than the QNP-6250H's PoE+ (Class 4, 23 W max), so existing PoE+ infrastructure will require injectors or switch upgrades. The QNP-6250H is the better fit where PoE+ infrastructure is already deployed, Wisenet/NTCIP integration is required, and budget or power-plant constraints favor lower draw.
Is the QNP-6250H or WV-S66300-Z3 better for low-light performance?
The i-PRO WV-S66300-Z3 specifies a minimum illumination of 0.006 lux, compared to 0.05 lux color / 0.005 lux B/W on the Hanwha QNP-6250H. The i-PRO also achieves a higher stated maximum WDR of 144 dB (Super Dynamic Level 31) versus 120 dB on the Hanwha, giving it an edge in high-contrast, mixed-lighting scenes. Note that the two manufacturers measure and report illumination differently, so direct lux comparisons should be treated as indicative rather than absolute.
Can I power either camera from my existing PoE+ switch?
The Hanwha QNP-6250H is powered by PoE+ (IEEE 802.3at, Class 4) at a maximum of 23 W, so it is compatible with standard PoE+ switches. The i-PRO WV-S66300-Z3 requires PoE++ (Class 6) at 37.8 W, which exceeds the PoE+ standard. To power the WV-S66300-Z3 from a PoE+ switch, you would need a PoE++ midspan injector or a switch upgrade — a real infrastructure cost to factor into the project budget.
Which camera offers better built-in AI analytics — the QNP-6250H or the WV-S66300-Z3?
The i-PRO WV-S66300-Z3 provides a broader on-camera AI analytics suite: AI-classified video motion detection, face detection, people detection, vehicle detection, non-mask detection, occupancy detection, scene change detection, and AI sound classification for gunshot, yell, vehicle horn, and glass break — all processed on the Ambarella CV25m SoC. The Hanwha QNP-6250H offers directional detection, enter/exit detection, virtual line crossing, tampering, and motion detection, but does not specify AI object-class differentiation or sound classification in the provided specs.
