Hanwha QNP-6250H vs Hanwha QNP-6320H: Specification Comparison
The Hanwha QNP-6250H and QNP-6320H are both 2MP outdoor PTZ dome cameras sharing the same 1/2.8" CMOS sensor, 1920×1080 resolution, and 60fps frame rate — a true cross-shop pair for installers specifying pan-tilt-zoom coverage at perimeter or wide-area sites. The primary differentiator is optical zoom ratio: 25x on the 6250H versus 32x on the 6320H. This comparison evaluates how that lens difference cascades into real-world detection distances, and whether any other specs diverge meaningfully for your project.

How do the imaging specs compare?
Both cameras share the same 1/2.8" CMOS sensor, 1920×1080 resolution at up to 60fps, identical minimum illumination of 0.05 Lux color / 0.005 Lux B/W, 120dB WDR, SSNR V digital noise reduction, Day/Night Auto(ICR), and a built-in gyro-based digital image stabilizer. The wide-end field of view is identical at H: 64.66°, V: 38.08°, and minimum object distance is the same (Wide: 1.5m, Tele: 2m). Backlight compensation features — BLC, HLC, WDR, SSDR — are identical across both models.
The key optical difference is zoom ratio: the QNP-6250H offers a 4.44–111mm / 25x optical lens (digital 32x, total 800x combined), while the QNP-6320H extends to 4.44–142.6mm / 32x optical (digital 32x, total 1024x combined). This directly impacts tele-end DORI distances per the provided specs: at Detect tier, the 6320H reaches 1,921.3m vs 1,471.3m for the 6250H; at Identify tier, 192.1m vs 147.1m. Wide-end DORI figures are identical. Aperture at the tele end differs slightly: F3.9 on the 6250H vs F4.4 on the 6320H, meaning the 6250H admits marginally more light at full zoom. Neither model lists IR illuminators or IR viewable length in the provided specs — both spec sheets indicate IR-related fields as None for built-in illumination hardware.
What about installation and environment?
Both cameras are rated IP66, IK10, and NEMA4X, and carry identical operating temperature ranges of -35°C to +55°C with 0–95% RH non-condensing, and storage temperature of -50°C to +60°C. Power input is PoE+ (IEEE 802.3at, Class 4) on both, with identical power draw: Max 23W, typical 14W. Physical dimensions and weight are identical: ø204.3×265mm and 2700g.
Mounting accessory compatibility is identical across both models: Hanging Mount SBP-156HMW, Wall Mounts SBP-156WMW and SBP-390WMW2, Pole Mount SBP-300PMW2, Parapet Mounts SBP-156LMW and SBP-300LMW, Corner Mounts SBP-156KMW and SBP-300KMW1, and Cabinet SBP-300NBW. The 6250H spec lists a ceiling mount assembly model reference (SBP-156HMW context); the 6320H describes the ceiling option as 'Ceiling mount assembly kit' without a specific part number in the provided spec. Both share RAL9003 white body/aluminum and black polycarbonate head construction.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profile S/G/T, Hanwha SUNAPI (HTTP API), and the Wisenet open platform, ensuring broad VMS compatibility. Network protocol support is identical on both: IPv4/IPv6, RTP, RTSP, HTTPS, SNMPv1/v2c/v3, SRTP (TCP/UDP Unicast), NTCIP1205, and more. Security features are substantially the same — firmware encryption, Digest Authentication, brute-force prevention, 802.1X (EAP-TLS/LEAP/PEAP), HTTPS/SRTP/WSS secure communication, IP address filtering, device certificate (Hanwha Techwin Root CA), and user/system/event audit logs. One noted difference: the QNP-6320H spec lists Data Protect as 'AES Encryption, ZIP Compression,' while the QNP-6250H spec lists 'Authentication & ZIP encryption' — the 6320H explicitly names AES.
Edge analytics are identical on both: directional detection, motion detection (8 zones, 8-point polygonal), Enter/Exit, tampering, virtual line, and audio detection via optional SPM-4210 I/O box. Auto tracking is supported on both. Neither model includes built-in audio input or output per the provided specs. Edge storage is identical: 1× Micro SD/SDHC/SDXC slot, max 256GB. RAM and flash are the same: 1GB RAM, 256MB Flash. Smart codec WiseStream II with 5-area manual mode is present on both. The QNP-6250H spec describes video quality adjustment as 'H.264/H.265/MJPEG bitrate control'; the QNP-6320H describes it as 'Bitrate level control' — functionally equivalent per the specs provided.
Which should you choose: the QNP-6250H or the QNP-6320H?
Our take: The QNP-6320H is the stronger choice when maximum tele-end detection range is the primary requirement. The 32x optical zoom (vs 25x on the 6250H) extends tele Detect range to 1,921.3m vs 1,471.3m — a 450m advantage — and Identify range to 192.1m vs 147.1m, a 45m gain. For sites demanding the longest reach from a single PTZ head (large perimeter, ports, campuses), that lens difference is decisive. The QNP-6250H's tele aperture of F3.9 vs the 6320H's F4.4 gives a marginal low-light edge at full zoom, which matters in poorly lit tele-end scenarios. All other decision-relevant specs — sensor, resolution, frame rate, WDR, DORI wide-end figures, power, environmental ratings, mounting, ONVIF compliance, edge storage, and analytics — are identical between both models per the provided specifications.

Frequently Asked Questions
Which should you choose: the QNP-6250H or the QNP-6320H?
The QNP-6320H is the stronger choice when maximum tele-end detection range is the primary requirement. The 32x optical zoom (vs 25x on the 6250H) extends tele Detect range to 1,921.3m vs 1,471.3m — a 450m advantage — and Identify range to 192.1m vs 147.1m, a 45m gain. For sites demanding the longest reach from a single PTZ head (large perimeter, ports, campuses), that lens difference is decisive. The QNP-6250H's tele aperture of F3.9 vs the 6320H's F4.4 gives a marginal low-light edge at full zoom, which matters in poorly lit tele-end scenarios.
