i-PRO S22500-V3LG vs i-PRO X25500-V3LN: Specification Comparison
Both the i-PRO WV-S22500-V3LG and WV-X25500-V3LN are 5MP fixed dome cameras sharing the same 1/2.8-type CMOS sensor, 3.1x motorized varifocal lens (2.9–9mm), and 30fps frame rate—making them direct cross-shop candidates for buyers choosing between an IK10 indoor vandal dome and a hardened outdoor dome. The key differentiators are deployment environment (indoor vs. outdoor rated), IR throw distance, PoE class, SoC generation, and operating temperature range.

How do the imaging specs compare?
Both cameras deliver 5MP resolution at 30fps with a maximum 3072×2304 (4:3) or 3072×1728 (16:9) output, the same 1/2.8-type CMOS sensor, identical 2.9–9mm focal length at f/1.3–f/2.5, and identical 132dB maximum dynamic range (Super Dynamic on, Level 31). Shutter speed ranges differ slightly: the S22500-V3LG spans 1/30–1/10000 s while the X25500-V3LN spans 1/60–1/10000 s. The X25500-V3LN also specifies a maximum shutter of 1/4000 s. DORI distances are nearly identical at tele (Identify: 20.7m/68.1ft for both); at wide, the X25500-V3LN has a marginal edge (Identify 4.9m vs. 4.7m).
The most consequential imaging difference is IR range: the S22500-V3LG specifies 25m maximum IR illumination, while the X25500-V3LN reaches 70m (230ft)—a 2.8× advantage for perimeter or long-corridor applications. Minimum illumination is specified differently across the two datasheets: the S22500-V3LG lists 0.15 lux color / 0.12 lux B&W (F1.3), while the X25500-V3LN lists only 0.02 lux (B&W, IR LED); direct color-mode comparison is not possible from available specs. The X25500-V3LN also adds an image stabilizer (on/off, 30fps mode only) and a higher extra-zoom ceiling of 12.4x vs. 9.3x at 640×360 resolution. The X25500-V3LN runs on an Ambarella CV52 SoC versus the CV22 in the S22500-V3LG, a newer chip generation.
What about installation and environment?
The S22500-V3LG is rated for indoor use only with no IP ingress rating specified; it carries IK10 impact resistance (IEC 62262). Operating temperature is −10°C to +50°C (power-on: 0°C to +50°C) with 10–90% humidity (no condensation). It draws up to 12W and accepts DC 12V or PoE IEEE 802.3af (PoE Class 0). The body is aluminum die-cast with a polycarbonate dome, weighing approximately 800g (1.77 lbs) at ø129.5mm × 102.5mm (H).
The X25500-V3LN is designed for outdoor deployment, rated IP66/IP67 (IEC 60529), NEMA 4X (UL50E), and IK10 (IEC 62262) with a 50J shock rating (IEC 60068-2-75) and wind resistance up to 40m/s (~89mph). Operating temperature spans −40°C to +55°C (power-on: −30°C to +55°C) with 10–100% humidity (no condensation)—a dramatically broader envelope. It requires PoE+ IEEE 802.3at (Class 4) at up to 14.2W max; DC 12V is also supported. The body is aluminum die-cast with stainless steel and PC resin, weighing approximately 1.1kg (2.43 lbs) at ø154mm × 105mm (H). Both units carry identical safety certifications (UL62368-1, c-UL, CE, IEC62368-1); EMC differs at EN55032 Class B (S22500-V3LG) vs. Class A (X25500-V3LN).
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, M, S, and T; up to 14 simultaneous users; H.265/H.264/MJPEG compression; microSDXC up to 512GB on-board storage; G.726, G.711 audio compression; full-duplex audio; 3x alarm inputs and 1x AUX output; VMD (4 areas) and SCD (1 area); and privacy masking up to 8 zones. The X25500-V3LN adds AAC-LC audio compression and specifies TCP alerts as an alarm action not listed for the S22500-V3LG. IPv6 protocol support differs: the S22500-V3LG lists MQTT and RTSP under IPv6, while the X25500-V3LN includes DHCPv6 and MLD.
Both cameras specify AI analytics including face, vehicle, and sound classification (gunshot, yell, vehicle horn, glass break). The S22500-V3LG lists AI Motion, Face, and Vehicle Detection explicitly; the X25500-V3LN specifies '8 detection types' under AI Video Analytics without enumerating all eight in the provided spec. The S22500-V3LG carries FIPS 140-2 Level 3 certification with NXP EdgeLock SE050F secure element, a hardware security credential not listed for the X25500-V3LN in the provided specs; the X25500-V3LN lists Secure Boot as a feature, which is not explicitly listed for the S22500-V3LG. Both support signed firmware and HTTPS encryption.
Which should you choose: the S22500-V3LG or the X25500-V3LN?
Our take: The X25500-V3LN is the stronger choice when the installation is outdoor or in any environment requiring weatherproofing, extended temperature coverage, or long-range IR illumination. Its IP66/IP67/NEMA 4X rating versus no IP rating on the S22500-V3LG makes the X25500-V3LN the only viable option for exterior deployment. IR throw is 70m vs. 25m—a 2.8× advantage that directly affects perimeter coverage area. The temperature floor drops to −40°C vs. −10°C, covering cold-climate outdoor sites entirely outside the S22500-V3LG's envelope. The tradeoff is PoE+/Class 4 (14.2W) vs. PoE/Class 0 (12W), which requires verifying switch port budgets. The S22500-V3LG is the correct choice for indoor vandal-resistant applications where FIPS 140-2 Level 3 hardware security certification is a compliance requirement and standard PoE infrastructure is already in place.

Frequently Asked Questions
Which should you choose: the S22500-V3LG or the X25500-V3LN?
The X25500-V3LN is the stronger choice when the installation is outdoor or in any environment requiring weatherproofing, extended temperature coverage, or long-range IR illumination. Its IP66/IP67/NEMA 4X rating versus no IP rating on the S22500-V3LG makes the X25500-V3LN the only viable option for exterior deployment. IR throw is 70m vs. 25m—a 2.8× advantage that directly affects perimeter coverage area. The temperature floor drops to −40°C vs. −10°C, covering cold-climate outdoor sites entirely outside the S22500-V3LG's envelope. The tradeoff is PoE+/Class 4 (14.2W) vs. PoE/Class 0 (12W), which requires verifying switch port budgets. The S22500-V3LG is the correct choice for indoor vandal-resistant applications where FIPS 140-2 Level 3 hardware security certification is a compliance requirement and standard PoE infrastructure is already in place.
Is the S22500-V3LG or X25500-V3LN better for low-light performance?
The X25500-V3LN specifies a minimum illumination of 0.02 lux (B&W, IR LED) and a 70m IR range, versus the S22500-V3LG's 0.15 lux color / 0.12 lux B&W and 25m IR. On the available specs, the X25500-V3LN has a lower B&W illumination floor and substantially longer IR throw, making it the stronger performer in dark or large-area scenes. Note that the S22500-V3LG's color-mode floor (0.15 lux) cannot be directly compared to the X25500-V3LN since its specs do not list a separate color-mode illumination figure.
Can I use the S22500-V3LG outdoors if I install it in an outdoor enclosure?
The S22500-V3LG carries no IP ingress rating per the provided specifications, so i-PRO does not rate it for direct outdoor exposure. Installing it inside a third-party outdoor enclosure may be physically possible but would fall outside the manufacturer's specified operating conditions. For any outdoor application, the X25500-V3LN is the factory-rated choice at IP66/IP67 and NEMA 4X.
Do both cameras work with the same PoE switches, or does one require an upgrade?
The S22500-V3LG requires standard PoE (IEEE 802.3af, up to 12W, Class 0), which any 802.3af-compliant switch port can supply. The X25500-V3LN requires PoE+ (IEEE 802.3at, up to 14.2W, Class 4); a switch port that only delivers 802.3af (15.4W budget but Class 0 negotiation may limit output) may not reliably power it. Verify that each X25500-V3LN port on your switch is rated for 802.3at Class 4 before deployment.
