i-PRO S35402-F2LG vs i-PRO X35402-F2L: Specification Comparison
Both the i-PRO WV-S35402-F2LG and WV-X35402-F2L are 4MP compact dome IP cameras sharing the same 2.4mm fixed lens, 1/2.8-type CMOS sensor, Ambarella CV25M SoC, and IP66/IK10-rated aluminum die-cast housing. They target the same resolution class and camera type, making them direct cross-shop candidates. The comparison focuses on where they diverge: low-light sensitivity, operating temperature ceiling, railway/vehicle certifications, and hardware security posture—differences that matter for vertical-specific deployments such as transit, rail, and high-security facilities.

How do the imaging specs compare?
Both cameras deliver 4MP at 25/30 fps across identical resolution modes (2560×1440, 1920×1080, 1280×720 in 16:9; 1280×960 and 2048×1536 in 4:3) and share the same 2.4mm fixed lens at F2.1, providing 121° horizontal field of view, DORI distances (Detect 29.0m, Identify 2.9m), and a maximum 132 dB Super Dynamic range. The lens, aperture, focus range (0.7m to ∞), extra zoom (4.0× at 640×360), and image adjustment capabilities—adaptive black stretch, BLC/HLC 0–31, fog compensation 0–8, AGC 0–11—are identical between models.
Low-light performance is where the two diverge. The S35402-F2LG specifies 0.19 lx color at 30 IRE and 0.27 lx at 50 IRE, with 0.16 lx in B&W mode and 0 lx with IR active. The X35402-F2L specifies 0.07 lx color and 0.06 lx B&W; no 30/50 IRE breakout is provided in its supplied spec. On IR range, the S35402-F2LG datasheet notes 10m at 50 IRE and 14m at high mode, while the X35402-F2L spec lists IR LED range as 14m/10m max—the same LED hardware—though the derived marketing copy assigns the X model 14m at 30 IRE and 10m at 50 IRE. Both cameras include AI Sound Classification (Gunshot, Yell, Vehicle horn, Glass break) and the same AI Video Analytics suite: motion, face, people, vehicle, mask/non-mask, and occupancy detection.
What about installation and environment?
The two cameras share the same physical form factor: 109mm (W) × 53mm (H) × 119mm (D), approximately 475g, aluminum die-cast housing with tamper-resistant enclosure, IP66 (IEC 60529), NEMA 4X/Type 4X (UL50E), and IK10 (IEC 62262) impact resistance. Wind resistance is rated to 40 m/s (≈89 mph) on both. PoE power (IEEE 802.3af compliant) and maximum power draw of 8.6W are identical, and both use a single RJ45 10BASE-T/100BASE-TX interface. Adjusting angles are the same: pan −45° to +45°, tilt 0° to +90°, yaw −90° to +90°.
The operating temperature ceiling is the most concrete installation differentiator. The S35402-F2LG is rated −40°C to +50°C, while the X35402-F2L extends to −40°C to +60°C—a 10°C higher ceiling. Additionally, the X35402-F2L carries explicit railway and vehicle certifications (EN50155, JIS E 5006, IEC62236, EN50121) that are absent from the S35402-F2LG spec. The S35402-F2LG finish is described as aluminum die cast white/smoke; the X35402-F2L finish is aluminum die cast white with PC resin clear bubble. Operating humidity is 10%–100% (no condensation) on both.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, M, S, and T; identical IPv4 and IPv6 protocol stacks including RTSP, SRTP, MQTT, SFTP, SNMPv1/v2/v3, IEEE 802.1X, and DiffServ; up to 14 simultaneous users; microSDXC/SDHC/SD up to 512GB edge storage; alarm actions via email, HTTP, TCP, and SD card recording; mobile compatibility with iOS 8.0+ and Android; and the same browser support (Edge, Firefox, Chrome). Audio compression (G.726 ADPCM 32/16 kbps, G.711 64 kbps) and built-in microphone are present on both. Setup menu languages are identical (9 languages). The S35402-F2LG spec explicitly lists VMD across 4 areas and SCD across 1 area; the X35402-F2L lists the same.
The X35402-F2L adds a hardware-level security layer absent from the S35402-F2LG spec: FIPS 140-2 Level 3 compliance via an NXPR EdgeLock SE050F secure element, a pre-installed GlobalSign R device certificate, digest authentication, and host authentication, in addition to the brute-force protection and IEEE 802.1X shared by both. The X model also explicitly lists Smart Coding (Variable GOP 1–16s, Fixed GOP 60s option); this feature is not listed in the S35402-F2LG spec. For VMS integrations requiring zero-trust device identity or government/transit compliance mandates, the X35402-F2L's hardware security module is a material differentiator.
Which should you choose: the S35402-F2LG or the X35402-F2L?
Our take: The X35402-F2L is the stronger choice when the deployment demands railway/vehicle certification, a higher ambient temperature ceiling, or hardware-rooted cybersecurity compliance. Concretely: its operating temperature ceiling is 60°C versus 50°C for the S35402-F2LG; its minimum color illumination is 0.07 lx versus 0.19 lx (at 30 IRE) for the S-series; and it adds FIPS 140-2 Level 3 hardware security and EN50155/JIS E 5006/EN50121 transit certifications that the S35402-F2LG spec does not list. The S35402-F2LG, sharing the same sensor, lens, SoC, AI analytics, ONVIF profile set, PoE budget, and IP66/IK10 ratings, is appropriate for standard commercial and industrial outdoor deployments where transit certifications and the hardware secure element are not required. Select the X35402-F2L for transit, rail, or regulated-security environments; the S35402-F2LG for conventional perimeter or facility surveillance where those requirements are absent.

Frequently Asked Questions
Which should you choose: the S35402-F2LG or the X35402-F2L?
The X35402-F2L is the stronger choice when the deployment demands railway/vehicle certification, a higher ambient temperature ceiling, or hardware-rooted cybersecurity compliance. Concretely: its operating temperature ceiling is 60°C versus 50°C for the S35402-F2LG; its minimum color illumination is 0.07 lx versus 0.19 lx (at 30 IRE) for the S-series; and it adds FIPS 140-2 Level 3 hardware security and EN50155/JIS E 5006/EN50121 transit certifications that the S35402-F2LG spec does not list. The S35402-F2LG, sharing the same sensor, lens, SoC, AI analytics, ONVIF profile set, PoE budget, and IP66/IK10 ratings, is appropriate for standard commercial and industrial outdoor deployments where transit certifications and the hardware secure element are not required. Select the X35402-F2L for transit, rail, or regulated-security environments; the S35402-F2LG for conventional perimeter or facility surveillance where those requirements are absent.
Is the S35402-F2LG or X35402-F2L better for low-light performance?
Based on the supplied specifications, the X35402-F2L specifies a lower minimum color illumination—0.07 lx versus 0.19 lx at 30 IRE for the S35402-F2LG—and a lower B&W minimum of 0.06 lx versus 0.16 lx. Both models include IR LEDs rated at 14m (high) / 10m (medium) and reach 0 lx with IR active per the S-series spec; the X-series spec does not explicitly list a 0 lx IR figure. On the available spec data, the X35402-F2L has the advantage in passive low-light sensitivity.
Can either camera be used in railway or vehicle applications?
Only the X35402-F2L lists explicit railway and vehicle certifications: EN50155, JIS E 5006, IEC62236, and EN50121. The S35402-F2LG spec does not include these certifications. If your deployment requires compliance with those standards—common in rolling stock, buses, or trackside enclosures—the X35402-F2L is the only option of the two supported by the provided specifications.
Do both cameras support the same edge analytics and VMS integration features?
Yes, in most respects. Both share ONVIF Profiles G/M/S/T, the same AI analytics set (motion, face, people, vehicle, mask, occupancy, sound classification), VMD (4 areas), SCD (1 area), up to 512GB microSDXC edge storage, and identical protocol stacks. The X35402-F2L additionally specifies Smart Coding (Variable GOP) and FIPS 140-2 Level 3 hardware security with a pre-installed device certificate—features not listed in the S35402-F2LG spec. For standard VMS integration without those requirements, both cameras are equivalent.
