i-PRO S66600-Z3 vs i-PRO X66600-Z3LS: Specification Comparison
Both the i-PRO WV-S66600-Z3 and WV-X66600-Z3LS are 6MP outdoor PTZ dome cameras built on the same 1/2.8-inch CMOS sensor platform with identical 30x optical zoom lenses, Ambarella CV22 SoC, and PoE++ power. They target the same perimeter-surveillance and city-safety buyer segments. The key differentiators lie in the X66600-Z3LS's built-in long-range IR illumination (280 m), its explicit 60 fps frame rate rating, and minor differences in finish materials, I/O terminal labeling, and power draw.

How do the imaging specs compare?
Both cameras share an identical optical core: 1/2.8-inch CMOS sensor with a 5.57 × 3.13 mm scanning area, 4.5–135 mm focal length, F1.8–F4.7 aperture, 30x motorized optical zoom extendable to 78x at 1280×720, and a 2.5°–62° horizontal field of view. Minimum illumination is 0.1 lux (B/W) on both. Maximum dynamic range is 132 dB (Super Dynamic On, Level 31) on both. Resolutions up to 3328×1872 (6MP) and identical DORI distance figures are shared across the line.
The most significant imaging delta is IR illumination. The X66600-Z3LS specifies integrated IR LED illumination rated to 280 m at 30 IRE / 200 m at 50 IRE; the S66600-Z3 lists no built-in IR range in its specs — its IR Distance field shows only 3.0 m, which aligns with the lens focus near-limit, not an illuminator distance, suggesting no meaningful long-range IR emitter is specified for that model. The X66600-Z3LS also carries an explicit 60 fps frame rate specification; the S66600-Z3 lists frame rate as 'Variable' with no maximum fps value stated in the provided specs.
What about installation and environment?
Both cameras share the same mechanical envelope (φ167 mm × 205 mm H, dome radius SR 77.5 mm), approximate mass (≈3 kg without attachment), wind resistance (up to 40 m/s / ≈89 mph), IP66 water/dust ingress rating, IK10 impact resistance per IEC 62262, and an ambient operating range of −50 °C to 60 °C (power-on: −30 °C to 60 °C, 10–100% RH non-condensing). Both are PoE++ (IEEE 802.3bt) Class 6 devices. The X66600-Z3LS specifies 54 V / 45.9 W; the S66600-Z3 specifies 37.8 W — a 8.1 W higher draw on the X model, relevant for PoE budget planning on managed switches.
The S66600-Z3 explicitly lists a NEMA-TS2 and Type 4X enclosure rating; the X66600-Z3LS lists NEMA-TS2 and its IP Rating field shows IP66 / NEMA 4X. Both carry identical safety certifications: UL/c-UL (UL62368-1 / CSA C22.2 No.62368-1), CE, IEC62368-1, FCC Part 15 Class A, ICES-003 Issue 7, EN55032 Class A, and EN55035. The S66600-Z3 finish is aluminum die cast with polycarbonate dome; the X66600-Z3LS adds stainless steel to that material list.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile G / M / S / T compliant, support up to 14 simultaneous users, and run on the Ambarella CV22 SoC with identical AI analytics: AI motion, privacy masking, face, people, and vehicle detection, plus AI sound classification (gunshot, yell, vehicle horn, glass break). Both support H.265 / H.264 / MJPEG compression, Smart Coding GOP control, IPv4 and IPv6 protocol stacks including HTTPS, SRTP, MQTT, and NTCIP, and mobile access via iOS 8.0+ and Android. Both list image stabilization via built-in gyro sensor, 256 preset positions, auto-track / auto-pan / preset sequence / patrol auto modes, and FIPS 140-2 level 3 security (NXP EdgeLock SE050F) with GlobalSign device certificate.
Audio I/O differs in labeling detail: the S66600-Z3 specifies 4× 3.5 mm stereo audio inputs (−51 to −38 dB sensitivity) and 4 alarm terminals (IN/OUT); the X66600-Z3LS specifies 1× 3.5 mm stereo input and separately lists Alarm IN ×3, Alarm OUT ×1, and AUX OUT ×1 — a structurally different terminal count. On-board storage for the X66600-Z3LS explicitly details supported card capacities (64 GB–512 GB microSDXC / 4 GB–32 GB microSDHC) and recording modes (manual, alarm pre/post, schedule, network-failure backup); the S66600-Z3 lists only 'microSDXC memory card' without capacity bounds or recording-mode detail in the provided specs. Both are covered by a 5-year warranty.
Which should you choose: the S66600-Z3 or the X66600-Z3LS?
Our take: The X66600-Z3LS is the stronger choice when built-in long-range IR night vision is a project requirement. Its IR illuminators are rated to 280 m at 30 IRE — the S66600-Z3 provides no comparable long-range IR specification, making the X model the clear selection for unlit perimeter or parking environments. The X66600-Z3LS also carries an explicit 60 fps frame rate rating versus the S66600-Z3's unquantified 'Variable' fps, which matters for fast-moving target tracking or evidentiary-quality capture. However, the X model draws 45.9 W versus 37.8 W, an 8.1 W premium that can affect PoE switch budgets in dense deployments. If illuminated scenes, external lighting, or daytime-only operation remove the IR requirement, both cameras are otherwise specification-equivalent in sensor, optics, AI analytics, VMS integration, and environmental hardening.

Frequently Asked Questions
Which should you choose: the S66600-Z3 or the X66600-Z3LS?
The X66600-Z3LS is the stronger choice when built-in long-range IR night vision is a project requirement. Its IR illuminators are rated to 280 m at 30 IRE — the S66600-Z3 provides no comparable long-range IR specification, making the X model the clear selection for unlit perimeter or parking environments. The X66600-Z3LS also carries an explicit 60 fps frame rate rating versus the S66600-Z3's unquantified 'Variable' fps, which matters for fast-moving target tracking or evidentiary-quality capture. However, the X model draws 45.9 W versus 37.8 W, an 8.1 W premium that can affect PoE switch budgets in dense deployments. If illuminated scenes, external lighting, or daytime-only operation remove the IR requirement, both cameras are otherwise specification-equivalent in sensor, optics, AI analytics, VMS integration, and environmental hardening.
Is the S66600-Z3 or X66600-Z3LS better for low-light or nighttime surveillance?
Based on the provided specs, the X66600-Z3LS is the clear choice for low-light and nighttime use. It specifies integrated IR LED illumination rated to 280 m at 30 IRE / 200 m at 50 IRE. The S66600-Z3 lists no comparable IR range figure in its specifications — its 3.0 m IR Distance value corresponds to the lens minimum focus distance, not an illuminator range. If the scene has adequate external lighting, both cameras share the same 0.1 lux (B/W) minimum illumination threshold.
Will either camera strain my PoE switch budget more than the other?
Yes. The X66600-Z3LS is specified at 54 V / 45.9 W, while the S66600-Z3 is specified at 37.8 W. Both are PoE++ (IEEE 802.3bt) Class 6 devices, so both require a PoE++ capable port, but the X model draws approximately 8.1 W more per port. On a 24-port switch with a shared PoE budget, that difference becomes meaningful when deploying multiple units — verify per-port and total-switch PoE budgets before finalizing quantity.
Do both cameras support the same AI analytics and VMS integrations?
Yes, based on the provided specifications. Both cameras use the Ambarella CV22 SoC and list identical AI analytics: motion, privacy masking, face, people, and vehicle detection, plus AI sound classification for gunshot, yell, vehicle horn, and glass break. Both are ONVIF Profile G / M / S / T compliant and support the same browser and mobile client platforms. Protocol stacks — including HTTPS, SRTP, MQTT, and NTCIP — are listed for both models.
