How do the imaging specs compare?

The QNO-8080R uses a 1/2.8" CMOS sensor delivering 2592×1944 (5MP) at 30fps, with a motorized varifocal lens spanning 3.2–10mm (3.1× zoom ratio) and a maximum aperture of F1.6 at the wide end. Its horizontal field of view runs from 101° (wide) down to approximately 31° (tele). Minimum illumination is rated at 0.15 Lux in color mode and 0 Lux with the 850nm IR LEDs active, which provide a stated IR range of 30m (98.4ft). WDR is specified at 120dB. The i-PRO WV-X15501-Z1L is also a 5MP outdoor bullet, but its datasheet entry lists a fixed 4.7mm focal length alongside a separately listed 10× optical zoom—these two values are not fully reconciled in the provided specs, so buyers should confirm the actual optical configuration with i-PRO before purchase. IR is described as OptimizedIR at 850nm; specific IR range distance and minimum illumination figures are not present in the provided specification set.

On WDR, the QNO-8080R gives a hard number—120dB—while the i-PRO spec sheet uses the label 'Forensic WDR' without a dB rating in the supplied data. The QNO-8080R's DC auto iris, ICR-based day/night switching, and SSNR digital noise reduction are fully documented. The i-PRO lists image stabilization and OptimizedIR as features, and its broader operating temperature range (−40°C to +60°C versus the QNO-8080R's −30°C to +55°C) may indicate a more ruggedized optical assembly, though underlying sensor size is not specified in the provided i-PRO data.

What about installation and environment?

Both cameras carry IP66 weatherproofing and IK10 vandal resistance ratings, making both suitable for exposed outdoor mounting. The QNO-8080R is powered by PoE IEEE 802.3af (Class 3), drawing a maximum of 9.5W and a typical 7.3W—compatible with standard PoE switches without budget PoE or mid-span injectors. The i-PRO WV-X15501-Z1L specifies PoE++ (802.3bt, Class 4), meaning it requires a PoE++ capable switch or injector; installers must budget for compatible infrastructure. The QNO-8080R operating temperature range is −30°C to +55°C; the i-PRO is rated −40°C to +60°C, offering a wider thermal envelope on both ends.

The QNO-8080R's physical dimensions are ø91×322.9mm at 1,190g (2.62 lb), constructed from aluminum in a dark grey housing. Pan/tilt/rotate adjustment ranges are documented at 0°–360° / 0°–100° / 0°–360°. The i-PRO lists wall and bracket mount types; its dimensions are noted as variable depending on sunshade position, and weight is not present in the provided spec data. The QNO-8080R also lists an optional back-box accessory (SBO-126B). The i-PRO spec notes NEMA 4X compliance in the marketing tagline, though this does not appear explicitly in its structured spec fields.

Which fits your VMS and analytics better?

The QNO-8080R supports ONVIF Profile S/G/T, Hanwha's SUNAPI (HTTP API), and the Wisenet open platform. On-board analytics include motion detection, tampering, defocus detection, virtual area (intrusion/enter/exit), and virtual line (crossing/direction). It provides one alarm input and one alarm output, with edge storage up to 128GB via microSD/SDXC. Audio is not listed in the provided QNO-8080R specs. The i-PRO WV-X15501-Z1L supports ONVIF Profile S/T/G and is explicitly listed as compatible with Milestone XProtect and Axis Camera Station in its spec data—a detail absent from the QNO-8080R's provided specs. i-PRO's analytics cover intrusion detection, line crossing, and object classification, and the unit lists audio support with a built-in microphone, expanding its use in applications requiring audio capture. Both cameras support microSD edge storage; the i-PRO's maximum SD capacity is not specified in the provided data.

Security hardening documentation is more comprehensive in the QNO-8080R spec set: it lists 802.1X authentication (EAP-TLS, EAP-LEAP, EAP-PEAP MSCHAPv2), SRTP, WSS, SD card partition encryption, device certificate (Hanwha Private Root CA), digest authentication, and brute-force attack prevention. The i-PRO specifies signed firmware and secure boot as security features. Both list HTTPS encryption. The i-PRO's operating system is listed as Android in the provided spec data; implications for VMS client or edge app deployment should be confirmed with the manufacturer.

Which should you choose: the QNO-8080R or the X15501-Z1L?

Our take: The QNO-8080R is the stronger choice when the installer needs a fully documented imaging chain, known PoE Class 3 power budget, and a richer on-paper security posture at a standard PoE infrastructure cost. Its 120dB WDR rating, 0.15 Lux / 0 Lux IR sensitivity, and 30m IR range are concretely specified, while the i-PRO's equivalent figures are absent from the provided data. The QNO-8080R's PoE Class 3 (max 9.5W) is compatible with any standard 802.3af switch, whereas the i-PRO's PoE++ Class 4 requirement adds infrastructure cost or complexity. Conversely, the i-PRO WV-X15501-Z1L is the preferable pick when audio capture is required (built-in mic, documented audio input), when the site demands a wider operating temperature range (−40°C to +60°C vs. −30°C to +55°C), or when the VMS environment is Milestone XProtect or Axis Camera Station, for which i-PRO lists explicit compatibility. Buyers should obtain the full i-PRO datasheet to resolve the focal length ambiguity before finalizing either selection.
