i-PRO S35402-F2L vs i-PRO X35402-F2L: Specification Comparison
Both the i-PRO WV-S35402-F2L and WV-X35402-F2L are 4MP fixed outdoor dome cameras sharing the same sensor, lens, IR illuminator, and PoE power budget. They target different deployment contexts: the S-series is positioned as a general-purpose outdoor AI dome, while the X-series adds railway and vehicle-grade environmental certifications. This comparison examines imaging capability, environmental and installation characteristics, and analytics and integration features to help integrators and IT buyers select the right unit for their application.

How do the imaging specs compare?
Both cameras use an approximately 1/2.8-type CMOS sensor with a 5.12 mm (H) × 3.84 mm (V) scanning area, a 2.4 mm fixed focal length lens at F2.1, and a 121° horizontal field of view (16:9). Dynamic range is identical at 132 dB maximum with Super Dynamic on at level 31. IR illumination is specified identically on both: 14 m at 30IRE and 10 m at 50IRE. Minimum B&W illumination is 0.06 lux on both models. The X35402-F2L additionally specifies a color minimum illumination of 0.07 lux; the S35402-F2L spec sheet does not list a separate color minimum illumination figure.
On resolution, the S35402-F2L specifies a native output of 2688×1520 (approximately 4MP at 16:9). The X35402-F2L lists resolutions of 2560×1440 and 1920×1080 in 16:9 mode, and 2048×1536 and 1280×960 in 4:3 mode; a single maximum pixel count equivalent to 2688×1520 is not stated in the provided X-series specs. DORI distances are identical across both units: Detect 29.0 m, Observe 11.6 m, Recognize 5.8 m, Identify 2.9 m. Both use the Ambarella CV25M SoC, extra zoom up to 4.0× at 640×360, and identical shutter range of 1/10000 s to 16/30 s. Frame rate is listed as 'High' for the S35402-F2L and explicitly as 25/30 fps for the X35402-F2L; the underlying capability is expected to be equivalent but only the X-series spec quantifies it.
What about installation and environment?
Physical form factor and power requirements are identical: both measure 109 mm (W) × 53 mm (H) × 119 mm (D), weigh approximately 475 g, draw a maximum of 8.6 W via PoE (IEEE 802.3af, PoE Class 0), and share the same aluminum die-cast white / PC resin clear finish with a tamper-resistant enclosure. Both achieve IP66 (IEC 60529), Type 4X (UL50E), NEMA 4X, and IK10 (IEC 62262) ratings, with wind resistance up to 40 m/s (~89 mph). Humidity tolerance is 10–100% (non-condensing) on both.
The key environmental difference is operating temperature. The S35402-F2L is rated -40 °C to +50 °C (power-on range -20 °C to +50 °C), whereas the X35402-F2L is rated -40 °C to +60 °C with no stated power-on restriction cited in the provided specs. That 10 °C higher upper limit and the X-series' additional railway and vehicle certifications — EN50155, JIS E 5006, IEC62236, and EN50121 — make the X35402-F2L the specified choice for transit rolling-stock or industrial enclosures subject to elevated temperatures. For standard outdoor building perimeter applications within the +50 °C ceiling, both units are otherwise installation-equivalent.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, M, S, and T; the same browser set (Edge, Firefox, Chrome); IPv4 and IPv6 protocol stacks including RTSP, SRTP, MQTT, SFTP, and SNMPv1/v2/v3; up to 14 simultaneous users; and microSDXC edge storage up to 512 GB. Audio compression is identical: G.726 (ADPCM) at 32/16 kbps and G.711 at 64 kbps. VMD covers 4 areas, SCD covers 1 area, and privacy masking allows up to 8 zones on both models.
AI analytics differ slightly in stated scope. The S35402-F2L lists AI Video Motion Detection plus Face, People, and Vehicle Detection. The X35402-F2L lists AI motion, face, people, vehicle, mask, and occupancy detection — explicitly adding non-mask detection and occupancy counting in its provided spec. AI Sound Classification (Gunshot, Yell, Vehicle horn, Glass break) is listed on both. Security posture is substantially the same — FIPS 140-2 Level 3, HTTPS, IEEE 802.1X — but the X35402-F2L additionally calls out NXP EdgeLock SE050F secure element and a pre-installed GlobalSign device certificate, which the S35402-F2L spec does not enumerate. Alarm action sets are comparable, with the X-series spec explicitly noting SD card recording as an alarm action.
Which should you choose: the S35402-F2L or the X35402-F2L?
Our take: The X35402-F2L is the stronger choice when the deployment involves rail vehicles, transit cabins, or industrial environments where temperatures can reach +60 °C or where EN50155/EN50121 compliance is a contract requirement. Against the S35402-F2L, the X-series gains a 10 °C higher upper operating limit (+60 °C vs +50 °C), adds explicit railway certifications (EN50155, JIS E 5006, IEC62236, EN50121), and extends the on-device analytics set to include non-mask detection and occupancy counting — all at identical physical size, weight, PoE power draw, lens, IR range, and dynamic range. It also carries a longer warranty (5 years vs 3 years per provided specs). For general-purpose outdoor perimeter surveillance on buildings where temperatures stay within +50 °C and transit certifications are not required, the S35402-F2L covers the same imaging and AI baseline at a likely lower acquisition cost, though no pricing data was provided for either model.

Frequently Asked Questions
Which should you choose: the S35402-F2L or the X35402-F2L?
The X35402-F2L is the stronger choice when the deployment involves rail vehicles, transit cabins, or industrial environments where temperatures can reach +60 °C or where EN50155/EN50121 compliance is a contract requirement. Against the S35402-F2L, the X-series gains a 10 °C higher upper operating limit (+60 °C vs +50 °C), adds explicit railway certifications (EN50155, JIS E 5006, IEC62236, EN50121), and extends the on-device analytics set to include non-mask detection and occupancy counting — all at identical physical size, weight, PoE power draw, lens, IR range, and dynamic range. It also carries a longer warranty (5 years vs 3 years per provided specs). For general-purpose outdoor perimeter surveillance on buildings where temperatures stay within +50 °C and transit certifications are not required, the S35402-F2L covers the same imaging and AI baseline at a likely lower acquisition cost, though no pricing data was provided for either model.
Is the S35402-F2L or X35402-F2L better for low-light performance?
Based on the provided specifications, both cameras share the same B&W minimum illumination of 0.06 lux and identical IR illumination of 14 m at 30IRE / 10 m at 50IRE. The X35402-F2L additionally specifies a color minimum illumination of 0.07 lux; the S35402-F2L spec does not state a separate color figure. Neither camera has a specified low-light advantage over the other based on available data.
Can I use the X35402-F2L on a bus or train, and does the S35402-F2L qualify for that too?
The X35402-F2L is explicitly specified to EN50155, JIS E 5006, IEC62236, and EN50121 — the railway and vehicle EMC/environmental standards commonly required for rolling-stock procurement. Its operating temperature also extends to +60 °C. The S35402-F2L spec sheet does not list any of those railway certifications, and its upper operating limit is +50 °C. For transit vehicle deployments where those certifications are contractually required, only the X35402-F2L is specified to meet them.
Do both cameras support edge storage and the same VMS integrations?
Yes. Both support microSDXC up to 512 GB for on-camera recording, ONVIF Profiles G, M, S, and T for broad VMS compatibility, and the same IPv4/IPv6 protocol stack including RTSP, MQTT, and SFTP. The X35402-F2L spec explicitly lists SD card recording as an alarm action; the S35402-F2L spec lists email, HTTP, and TCP alarm notification without separately calling out SD recording in that section, though both carry microSD slots.
