i-PRO S66600-Z3L vs i-PRO X66600-Z3S: Specification Comparison
Both the i-PRO WV-S66600-Z3L and WV-X66600-Z3S are 6MP outdoor PTZ dome cameras sharing the same 1/2.8-type CMOS sensor, 30x motorized optical zoom lens, and Ambarella CV22 SoC. They target perimeter surveillance installers who need long-range AI-assisted PTZ coverage. This comparison examines the meaningful differences in low-light performance, IR range, power draw, I/O configuration, protocol support, and warranty term to help integrators and IT buyers select the right unit for their deployment.

How do the imaging specs compare?
Both cameras use the same 1/2.8-type CMOS sensor (5.57 × 3.13 mm scanning area), the same 4.5–135 mm motorized lens at 30x optical zoom (up to 78x extra zoom at 1280×720), and produce identical DORI figures: Detect 110.8 m wide / 3050.4 m tele, Identify 11.1 m wide / 305.0 m tele. Maximum dynamic range is 132 dB on both (Super Dynamic On, Level 31), aperture ranges from F1.8 (wide) to F4.7 (tele) on both, and both share the same shutter range of 1/30–1/10000 s with maximum shutter extension to 16 s.
Low-light performance is where the models diverge. The S66600-Z3L is specified at 0.13 Lux (Color, 30IRE) for minimum illumination, whereas the X66600-Z3S is specified at 0.1 Lux (BW, 50IRE, F1.8, 1/30s) — note the S model's figure is color-mode and the X model's is B&W mode, so a direct numerical comparison must account for different test conditions. IR range is a more significant differentiator: the S66600-Z3L lists an IR LED range of 280 m (High) / 200 m (Medium), while the X66600-Z3S spec sheet lists 3.0 m as the IR distance in the structured spec fields (with the marketing tagline citing 20–30 m), making the S66600-Z3L's IR illumination reach substantially greater per the available specifications.
What about installation and environment?
Both cameras share the same physical envelope — φ167 mm × 205 mm (H), dome radius SR 77.5 mm, approximately 3 kg without attachment — and both carry IP66 water/dust resistance, IK10 impact resistance, NEMA-TS2 certification, and wind resistance up to 40 m/s (≈89 mph). Operating temperature range is identical: –50 °C to 60 °C ambient (power-on range –30 °C to +60 °C). Both use the same RJ45 10/100Base-TX interface and are PoE++ Class 6.
Power draw differs: the S66600-Z3L is rated at 45.9 W, while the X66600-Z3S is rated at 37.8 W — a difference of 8.1 W that matters when budgeting PoE++ switch port capacity over a large deployment. The S66600-Z3L also specifies DC 54 V as an alternative power input; the X66600-Z3S spec lists only PoE++ 37.8 W without mentioning an alternate DC input. Both have a tamper-resistant enclosure and aluminum/stainless-steel/polycarbonate construction (the X model specifies aluminum die-cast specifically).
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, M, S, and T, and both support H.265, H.264, and MJPEG at identical resolution steps (3328×1872 down to 320×180) with up to 14 simultaneous users. Both carry AI analytics including motion, face, people, and vehicle detection, plus AI sound classification (gunshot, yell, vehicle horn, glass break). The S66600-Z3L lists eight AI detection types explicitly; the X66600-Z3S describes AI motion, privacy, face, people, and vehicle detection. Both include VMD (4 areas), SCD (1 area), up to 32 privacy zones, 8 VIQS zones, Active ClearSight, image stabilization via built-in gyro, and the same pan/tilt speeds (700°/s preset pan, 500°/s preset tilt).
Protocol and I/O differences are relevant for integration depth. The X66600-Z3S explicitly lists SRTP, MQTT, and NTCIP in its IPv4 protocol stack — protocols not listed for the S66600-Z3L in the provided specs. For I/O, the S66600-Z3L provides 4 alarm terminals (2 IN, 1 OUT, 1 AUX OUT) and 4× 3.5 mm audio inputs plus 1 audio output; the X66600-Z3S provides 3 alarm I/O terminals (IN1/IN2/IN3, OUT) and a single 3.5 mm stereo audio input plus mono audio output. On-board storage: the S66600-Z3L references microSDXC support; the X66600-Z3S specifies 64 GB–512 GB microSDXC or 4 GB–32 GB microSDHC with explicit recording modes (Manual, Alarm, Schedule, Backup). Warranty is 3 years for the S66600-Z3L and 5 years for the X66600-Z3S per the provided specs.
Which should you choose: the S66600-Z3L or the X66600-Z3S?
Our take: The S66600-Z3L is the stronger choice when long-range IR illumination is the primary requirement: its specified IR range of 280 m (High) dwarfs the X66600-Z3S's spec-listed 3.0 m IR distance, making it the clear selection for large open perimeters or parking areas where darkness extends beyond 30 m. Conversely, the X66600-Z3S draws 37.8 W versus the S66600-Z3L's 45.9 W — a meaningful 8.1 W saving per port in dense PoE++ deployments — and it adds SRTP, MQTT, and NTCIP to its protocol stack, which benefits smart-city traffic and IoT-integrated platforms. The X66600-Z3S also carries a 5-year warranty versus the S66600-Z3L's 3-year term. For installations prioritising deep IR coverage and maximum low-light reach, specify the S66600-Z3L; for lower power budgets, broader protocol ecosystems, or sites requiring NTCIP compliance, the X66600-Z3S is the better fit.

Frequently Asked Questions
Which should you choose: the S66600-Z3L or the X66600-Z3S?
The S66600-Z3L is the stronger choice when long-range IR illumination is the primary requirement: its specified IR range of 280 m (High) dwarfs the X66600-Z3S's spec-listed 3.0 m IR distance, making it the clear selection for large open perimeters or parking areas where darkness extends beyond 30 m. Conversely, the X66600-Z3S draws 37.8 W versus the S66600-Z3L's 45.9 W — a meaningful 8.1 W saving per port in dense PoE++ deployments — and it adds SRTP, MQTT, and NTCIP to its protocol stack, which benefits smart-city traffic and IoT-integrated platforms. The X66600-Z3S also carries a 5-year warranty versus the S66600-Z3L's 3-year term. For installations prioritising deep IR coverage and maximum low-light reach, specify the S66600-Z3L; for lower power budgets, broader protocol ecosystems, or sites requiring NTCIP compliance, the X66600-Z3S is the better fit.
Is the S66600-Z3L or X66600-Z3S better for low-light and night coverage?
Based on the provided specifications, the S66600-Z3L has a substantially longer IR range — 280 m (High) versus the X66600-Z3S's spec-listed 3.0 m IR distance — making it the stronger choice for scenes requiring IR illumination at range. Minimum illumination figures use different test conditions (S model: 0.13 Lux Color/30IRE; X model: 0.1 Lux BW/50IRE), so they are not directly comparable without identical test parameters.
Does either camera support MQTT or NTCIP for smart-city or traffic integration?
Yes — the X66600-Z3S explicitly lists SRTP, MQTT, and NTCIP in its IPv4 protocol stack per the provided specs. These protocols are not listed for the S66600-Z3L in the specifications provided, so if your VMS or traffic management platform requires MQTT or NTCIP, the X66600-Z3S is the confirmed choice.
Which camera puts less load on a PoE++ switch, and does the warranty differ?
The X66600-Z3S draws 37.8 W versus the S66600-Z3L's 45.9 W — a savings of 8.1 W per port, which adds up across a large installation when sizing PoE++ switches and cabling. On warranty, the X66600-Z3S carries a 5-year warranty while the S66600-Z3L carries a 3-year warranty, per the specifications provided.
