i-PRO S66300-Z3 vs i-PRO X66300-Z3S: Specification Comparison
Both the i-PRO WV-S66300-Z3 and WV-X66300-Z3S are 2MP outdoor PTZ dome cameras from i-PRO's S-series and X-series lines respectively. They share the same sensor size, optical zoom range, pan/tilt mechanics, and PoE++ power class, making them genuine cross-shop candidates for installers evaluating which tier fits a given deployment. This comparison examines imaging capabilities, environmental and installation factors, and integration features strictly from the provided specifications.

How do the imaging specs compare?
Both cameras use an approximately 1/2.8-type CMOS sensor with a 5.57 × 3.13 mm scanning area, a 32x optical zoom (4.25–136 mm, F1.6–F4.4), and an extended 48x zoom at 1280×720 resolution. Minimum illumination is specified at 0.006 lux for both units. Dynamic range reaches a maximum of 144 dB on both models when Super Dynamic is enabled at level 31. Frame rate tops out at 60 fps at 1920×1080 for both cameras. DORI figures are identical across all four tiers: Detect wide 60.3 m / tele 1833.2 m; Identify wide 6.0 m / tele 183.3 m.
A notable difference is the angular field-of-view specification detail: the S66300-Z3 provides both horizontal (2.4°–65°) and vertical (1.4°–39°) FOV figures, while the X66300-Z3S lists only a 65° wide horizontal figure for 16:9 mode and a 51° wide figure for 4:3 mode—vertical FOV at tele end is not provided in the X-series spec. The X66300-Z3S additionally specifies 4:3 mode resolutions (1280×960 and 2048×1536), which the S66300-Z3 spec does not list. Both carry a built-in gyro-based image stabilizer and Active ClearSight. Shutter speed ranges are equivalent at 1/60–1/10000 (60 fps mode).
What about installation and environment?
Both cameras share the same physical footprint: φ167 mm × 205 mm (H), dome radius SR 77.5 mm, and an approximate weight of 3 kg without attachment. Both use aluminum die-cast construction with a polycarbonate dome and a tamper-resistant enclosure rated IK10 (IEC 62262). Operating temperature range is identical at –50°C to +60°C, humidity 10–100% (non-condensing), and wind resistance up to 40 m/s (~89 mph).
Both units carry IP66 water and dust resistance. The S66300-Z3 spec explicitly lists NEMA 4X and Type 4X certifications; the X66300-Z3S spec lists NEMA-TS2 under Other Standards and IP66 under Water and Dust Resistance, but the X-series product attribute field also lists 'IP66, NEMA 4X'—both appear to carry the NEMA 4X rating per their attribute data. Power consumption for both is PoE++ at 37.8 W (IEEE 802.3bt Class 6). Network interface on both is 10Base-T / 100Base-TX via RJ45.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, M, S, and T, and both are compatible with Microsoft Edge, Firefox, and Google Chrome for browser-based access. Both support up to 14 simultaneous users, identical audio compression options (G.726, G.711, AAC-LC), and full-duplex audio transmission. AI analytics coverage overlaps substantially: both detect motion, faces, people, vehicles, non-mask, and occupancy. The S66300-Z3 spec explicitly names 'AI Scene Change Detection' as a distinct AI analytics function; the X66300-Z3S lists standard Scene Change Detection (SCD) separately, though AI-flagged listing does not appear in its AI analytics enumeration. The S66300-Z3 also explicitly lists 'AI Non mask Detection' and 'AI Occupancy Detection' in the AI analytics field, while the X66300-Z3S lists these in the general analytics attribute field.
The X66300-Z3S specification details a broader IPv4 protocol list, explicitly adding SRTP, MQTT, and NTCIP to the standard suite—none of these three are listed in the S66300-Z3 provided spec. MQTT support is significant for IoT/edge integration and NTCIP for traffic-system interoperability. The X66300-Z3S also explicitly documents SD card capacity range (64 GB–512 GB microSDXC / 4 GB–32 GB microSDHC) and lists all four SD recording modes (Manual, Alarm pre/post, Schedule, Backup-on-network-failure) for both H.265/H.264 and JPEG. The S66300-Z3 spec references microSDXC support without stating a capacity ceiling. Smart Coding on the X66300-Z3S adds a 'Frame rate control' GOP option not listed for the S66300-Z3. Both provide 3 alarm inputs and 1 alarm output, 3.5 mm audio in/out, and support FIPS 140-2 level 3 and 802.1X per the S66300-Z3 spec; the X66300-Z3S does not explicitly list FIPS 140-2 level 3 in the provided specification.
Which should you choose: the S66300-Z3 or the X66300-Z3S?
Our take: The X66300-Z3S is the stronger choice when the deployment requires broader protocol integration—specifically MQTT for IoT platforms, SRTP for encrypted RTP streams, or NTCIP for traffic-management systems, none of which appear in the S66300-Z3 specification. The X66300-Z3S also documents explicit microSDXC capacity support up to 512 GB and adds a Frame rate control GOP mode absent from the S66300-Z3 spec. Conversely, the S66300-Z3 explicitly carries FIPS 140-2 level 3 certification—a hard requirement for many federal and critical-infrastructure deployments—which is not listed in the X66300-Z3S provided specification. Both cameras are otherwise nearly identical: same 2MP/60 fps sensor, 32x optical zoom, 144 dB WDR, 0.006 lux minimum illumination, IK10/IP66 housing, PoE++ 37.8 W, and ONVIF G/M/S/T. Choose the S66300-Z3 for FIPS-mandated environments; choose the X66300-Z3S for IoT-integrated or traffic-system deployments requiring MQTT or NTCIP.

Frequently Asked Questions
Which should you choose: the S66300-Z3 or the X66300-Z3S?
The X66300-Z3S is the stronger choice when the deployment requires broader protocol integration—specifically MQTT for IoT platforms, SRTP for encrypted RTP streams, or NTCIP for traffic-management systems, none of which appear in the S66300-Z3 specification. The X66300-Z3S also documents explicit microSDXC capacity support up to 512 GB and adds a Frame rate control GOP mode absent from the S66300-Z3 spec. Conversely, the S66300-Z3 explicitly carries FIPS 140-2 level 3 certification—a hard requirement for many federal and critical-infrastructure deployments—which is not listed in the X66300-Z3S provided specification. Both cameras are otherwise nearly identical: same 2MP/60 fps sensor, 32x optical zoom, 144 dB WDR, 0.006 lux minimum illumination, IK10/IP66 housing, PoE++ 37.8 W, and ONVIF G/M/S/T. Choose the S66300-Z3 for FIPS-mandated environments; choose the X66300-Z3S for IoT-integrated or traffic-system deployments requiring MQTT or NTCIP.
Is the S66300-Z3 or X66300-Z3S better for low-light performance?
Based on the provided specifications, both cameras are equal in low-light performance. Both use the same approximately 1/2.8-type CMOS sensor, both specify a minimum illumination of 0.006 lux, and both achieve a maximum 144 dB dynamic range with Super Dynamic enabled at level 31. No specification difference distinguishes one from the other on low-light metrics.
Does the X66300-Z3S support more VMS and IoT integrations than the S66300-Z3?
Based on the provided specifications, the X66300-Z3S lists MQTT, SRTP, and NTCIP in its IPv4 protocol suite—protocols not present in the S66300-Z3 specification. MQTT enables integration with IoT and edge-management platforms; NTCIP is used in transportation and traffic-management systems. Both share ONVIF Profiles G, M, S, and T. If your VMS or infrastructure relies on any of those three additional protocols, the X66300-Z3S is the documented choice.
Which camera is required for a FIPS 140-2 compliant deployment?
The S66300-Z3 specification explicitly lists FIPS 140-2 level 3 certification. The X66300-Z3S provided specification does not list FIPS 140-2 level 3. If FIPS 140-2 level 3 is a hard compliance requirement for your project—common in federal, defense, or critical-infrastructure deployments—the S66300-Z3 is the model with that documented certification based on the specs provided.
