i-PRO S35402-F2LG vs i-PRO X35402-F2LM: Specification Comparison
Both the i-PRO WV-S35402-F2LG and WV-X35402-F2LM are 4MP fixed compact dome IP cameras sharing the same sensor size, focal length, SoC, and physical form factor. They target different deployment environments: the S35402-F2LG is a general-purpose outdoor dome, while the X35402-F2LM carries railway and transit certifications. This comparison examines where their imaging performance, environmental ratings, connectivity, and analytics capabilities diverge so integrators can select the right model for their application.

How do the imaging specs compare?
Both cameras use an approx. 1/2.8-type CMOS sensor with a 2.4 mm fixed lens, 121° horizontal field of view, F2.1 aperture, and identical DORI distances (Detect 29.0 m, Identify 2.9 m). Frame rate is 25/30 fps on both, and both achieve 132 dB dynamic range at Super Dynamic level 31. The key low-light difference is significant: the X35402-F2LM specifies 0.07 lx color and 0.06 lx B&W, versus 0.19 lx color at 30 IRE and 0.16 lx B&W on the S35402-F2LG — roughly 2.7× more sensitive in color and approximately 2.7× more sensitive in B&W.
IR illumination also differs. The X35402-F2LM specifies a single maximum IR range of 14 m (46 ft). The S35402-F2LG lists two IR power levels: 14 m high and 10 m medium, with the product card citing 10 m at 50 IRE as its headline figure. Both cameras reach 0 lx B&W with IR active. The X35402-F2LM also explicitly lists Smart Coding (Variable GOP 1–60 s, frame-rate control) as a spec; this is not listed for the S35402-F2LG.
What about installation and environment?
The two cameras share identical physical dimensions (109 mm W × 53 mm H × 119 mm D), weight (approx. 475 g), IP66/NEMA 4X/Type 4X water and dust rating, IK10 impact resistance, and wind resistance up to 40 m/s. Both are PoE-powered at 8.6 W max. The lower operating-temperature bound is identical at -40°C, but the X35402-F2LM is rated to +60°C versus +50°C for the S35402-F2LG, a meaningful 10°C headroom advantage in high-heat enclosures. The X35402-F2LM also notes a -20°C power-on temperature floor.
The network connector is a critical installation difference: the S35402-F2LG uses a standard RJ45, while the X35402-F2LM uses an M12 connector — the industrial locking connector required in railway, transit, and vibration-prone environments. Integrators must account for M12-to-RJ45 adapters or M12-terminated cable runs on the X model. The X35402-F2LM additionally carries railway/vehicle certifications: EN50155, JIS E 5006, IEC62236, EN50121, IEC61373, and EN45545 — none of which are listed for the S35402-F2LG.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, M, S, and T; H.265/H.264 with constant and variable bit rate; up to 14 simultaneous users; microSDXC/SDHC/SD local storage up to 512 GB; and the same audio compression codecs (G.711, G.726 ADPCM). Both include VMD (4 areas), SCD (1 area), audio detection, and AI sound classification (Gunshot, Yell, Vehicle horn, Glass break). The S35402-F2LG enumerates its AI analytics explicitly: AI Motion, Face, People, Vehicle, Mask, and Occupancy Detection. The X35402-F2LM states '7 detection types' without individually naming them in the provided spec data.
The X35402-F2LM lists explicit security certifications absent from the S35402-F2LG spec sheet: FIPS 140-2 Level 3, Device Certificate, and brute-force protection. Protocol support differs slightly — the S35402-F2LG lists a broader IPv6 protocol stack (SMTP, DNS, NTP, SNMPv1/v2/v3, DHCPv6, RTP, MLD, SFTP, MQTT, and others), while the X35402-F2LM's listed IPv6 stack is narrower (TCP/IP, UDP/IP, HTTP, HTTPS, SNMPv3 only per the provided spec). Both cameras support SD card recording as an alarm action; the S35402-F2LG spec explicitly lists this, while the X35402-F2LM alarm action spec states Email, HTTP, TCP notification and does not list SD card recording as an alarm action in the provided data.
Which should you choose: the S35402-F2LG or the X35402-F2LM?
Our take: The X35402-F2LM is the stronger choice when deploying in railway, transit, or high-vibration environments — the S35402-F2LG is the stronger choice for standard commercial or industrial outdoor installations where an RJ45 connection is required and the named AI analytics list matters. Three concrete spec deltas drive this: (1) low-light sensitivity — the X35402-F2LM achieves 0.07 lx color vs. 0.19 lx on the S35402-F2LG, a roughly 2.7× advantage; (2) operating temperature ceiling — +60°C vs. +50°C on the S model; (3) network connector — M12 (X model) vs. RJ45 (S model), which determines cabling compatibility entirely. The X model further adds FIPS 140-2 Level 3 certification and six railway standards (EN50155, EN45545, etc.) not present on the S model. Choose the S35402-F2LG for conventional IP infrastructure with RJ45 patch cabling and explicit analytics labeling; specify the X35402-F2LM for transit, rolling stock, or cybersecurity-regulated deployments.

Frequently Asked Questions
Which should you choose: the S35402-F2LG or the X35402-F2LM?
The X35402-F2LM is the stronger choice when deploying in railway, transit, or high-vibration environments — the S35402-F2LG is the stronger choice for standard commercial or industrial outdoor installations where an RJ45 connection is required and the named AI analytics list matters. Three concrete spec deltas drive this: (1) low-light sensitivity — the X35402-F2LM achieves 0.07 lx color vs. 0.19 lx on the S35402-F2LG, a roughly 2.7× advantage; (2) operating temperature ceiling — +60°C vs. +50°C on the S model; (3) network connector — M12 (X model) vs. RJ45 (S model), which determines cabling compatibility entirely. The X model further adds FIPS 140-2 Level 3 certification and six railway standards (EN50155, EN45545, etc.) not present on the S model. Choose the S35402-F2LG for conventional IP infrastructure with RJ45 patch cabling and explicit analytics labeling; specify the X35402-F2LM for transit, rolling stock, or cybersecurity-regulated deployments.
Is the S35402-F2LG or X35402-F2LM better for low-light performance?
Per the provided specs, the X35402-F2LM is the better low-light performer. It is rated at 0.07 lx color and 0.06 lx B&W, compared to 0.19 lx color (at 30 IRE) and 0.16 lx B&W on the S35402-F2LG. Both cameras reach 0 lx with IR active. The X model's IR range is also specified at 14 m maximum with no medium/low setting listed, while the S model lists 14 m high and 10 m medium.
Can I use a standard RJ45 cable with the X35402-F2LM?
No. The X35402-F2LM specifies an M12 connector for its network interface, not RJ45. The S35402-F2LG uses a standard RJ45 connector. If your infrastructure uses standard patch cables, you will need an M12-to-RJ45 adapter or M12-terminated cable for the X model. This is an installation-critical difference that affects conduit, junction box, and cable procurement.
Does the X35402-F2LM meet railway certifications that the S35402-F2LG does not?
Yes. The X35402-F2LM lists EN50155, JIS E 5006, IEC62236, EN50121, IEC61373, and EN45545 as railway/vehicle application certifications. None of these are listed in the provided spec data for the S35402-F2LG. If your project requires EN50155 or EN45545 compliance for rolling stock or trackside installation, only the X35402-F2LM meets that requirement based on the available specifications.
