i-PRO X4573LM vs Pelco SRXF3-12360-ES: Specification Comparison
Both the i-PRO WV-X4573LM and the Pelco SRXF3-12360-ES are 12MP fisheye cameras designed for wide-area panoramic surveillance in outdoor environments. This comparison examines how two leading manufacturer platforms approach the same resolution class and camera type—hemispheric fisheye—across imaging performance, installation requirements, and integration capabilities. The comparison is intended to help installers and IT buyers select the right platform for their VMS ecosystem, analytics requirements, and infrastructure constraints.

How do the imaging specs compare?
The i-PRO WV-X4573LM uses a 1/2-inch CMOS sensor with a 1.4 mm focal length at F1.9 aperture, delivering 12MP at a native 2992×2992 resolution—a square fisheye frame suited to ceiling-mount dewarping. Its minimum illumination is rated at 0.02 lx color and 0.003 lx B/W (F1.9, max shutter 16/30s, AGC 11), and it includes on-board IR LEDs with a stated maximum irradiation distance of 10 m (33 ft). WDR is rated at 84 dB max, adjustable across 0–31 levels. Maximum frame rate is 30 fps at full resolution.
The Pelco SRXF3-12360-ES is specified with a 2.7 mm focal length at F2.5 aperture (an aperture field also lists F2.0—the spec data is internally inconsistent on this point), producing 12MP output at 3840×2160—a widescreen 16:9 format. Maximum frame rate at full resolution is 12.5 fps. Minimum illumination is listed as 0.10 lux, and the specs note Day/Night capability with IR and 850 nm wavelength, but no IR range distance is provided in the available specifications. WDR is listed as supported with a stated range of up to 83 dB, though the spec entry is listed informally as 'Off Upto83dB' without confirmed bit-depth or adjustment levels. Neither IR range nor an exact WDR methodology is formally documented in the provided spec set.
What about installation and environment?
Both cameras carry IP66 and IK10 ratings. The Pelco SRXF3-12360-ES additionally carries an IP67 rating, indicating full temporary immersion protection beyond the i-PRO's IP66 dust-tight/water-jet rating. IK10 on both units denotes 50-joule impact resistance. The Pelco unit specifies an operating temperature range of -40°C to +60°C. No operating temperature range is provided in the available specifications for the i-PRO WV-X4573LM.
Power requirements differ meaningfully. The i-PRO WV-X4573LM draws 13W and is powered by standard 802.3af PoE, meaning it operates within the 15.4W Class 0–3 budget available from any 802.3af-compliant switch port. The Pelco SRXF3-12360-ES requires PoE+ (802.3at, PoE Class 3), raising the infrastructure requirement to a PoE+ capable switch port. Mounting options for the i-PRO include wall and ceiling. The Pelco lists wall, ceiling, pole, pendant, and corner mounts, offering broader mechanical flexibility. Both are form-factored as fisheye/dome units suited for outdoor deployment. The Pelco's physical dimensions are stated as 6" × 6" × 2.81"; no dimensions are provided in the i-PRO spec set.
Which fits your VMS and analytics better?
The i-PRO WV-X4573LM declares ONVIF Profile G, S, and T compliance. Profile G adds on-board recording and retrieval interoperability not covered by S or T alone, which can be relevant for edge-recording workflows. The Pelco SRXF3-12360-ES declares ONVIF Profile S and Profile T—no Profile G is listed. The i-PRO includes bundled i-VMD (Intelligent VMD, Type 8) analytics alongside standard VMD. The Pelco offers Pelco Smart Analytics with 8 behavior detection modes; these analytics are proprietary and their interoperability with third-party VMS platforms beyond ONVIF is not specified in the provided specs.
For audio, the i-PRO WV-X4573LM provides an audio input for an external microphone. The Pelco SRXF3-12360-ES notes microphone support. Neither unit specifies a built-in microphone in the provided spec data. On-board storage: the Pelco spec lists microSD card support; no edge storage capability is listed in the available i-PRO spec data. Video compression on the i-PRO includes H.265 and H.264; the primary Pelco spec entry lists H.264 only, though a secondary spec field also lists H.265—this inconsistency is present in the source specifications and cannot be resolved from the data provided. HTTPS encryption is listed as supported on the Pelco; no encryption spec is listed for the i-PRO in the provided data. The Pelco carries a stated 5-year warranty; no warranty term is listed for the i-PRO in the available specifications.
Which should you choose: the X4573LM or the SRXF3-12360-ES?
Our take: The WV-X4573LM is the stronger choice when low-light performance and standard PoE infrastructure are the primary constraints. Its minimum illumination of 0.02 lx color (vs. 0.10 lx on the Pelco) is a five-fold advantage in dim environments, and its 13W 802.3af draw avoids the PoE+ switch investment the Pelco requires. The i-PRO also delivers 30 fps at full 12MP versus 12.5 fps on the Pelco—a critical differentiator for fast-movement scenes and forensic review. Its ONVIF Profile G support extends interoperability to on-board recording workflows that the Pelco's Profile S/T pairing does not cover. Conversely, the Pelco SRXF3-12360-ES offers an additional IP67 rating, a documented -40°C cold-temperature floor, a broader five-mount mechanical portfolio, on-board microSD edge storage, and a stated 5-year warranty—none of which are matched in the available i-PRO spec data. Platform teams standardized on Pelco VMS or requiring sub-zero operating temperatures should weigh the Pelco's environmental and warranty profile accordingly.

Frequently Asked Questions
Which should you choose: the X4573LM or the SRXF3-12360-ES?
The WV-X4573LM is the stronger choice when low-light performance and standard PoE infrastructure are the primary constraints. Its minimum illumination of 0.02 lx color (vs. 0.10 lx on the Pelco) is a five-fold advantage in dim environments, and its 13W 802.3af draw avoids the PoE+ switch investment the Pelco requires. The i-PRO also delivers 30 fps at full 12MP versus 12.5 fps on the Pelco—a critical differentiator for fast-movement scenes and forensic review. Its ONVIF Profile G support extends interoperability to on-board recording workflows that the Pelco's Profile S/T pairing does not cover. Conversely, the Pelco SRXF3-12360-ES offers an additional IP67 rating, a documented -40°C cold-temperature floor, a broader five-mount mechanical portfolio, on-board microSD edge storage, and a stated 5-year warranty—none of which are matched in the available i-PRO spec data. Platform teams standardized on Pelco VMS or requiring sub-zero operating temperatures should weigh the Pelco's environmental and warranty profile accordingly.
Is the WV-X4573LM or SRXF3-12360-ES better for low-light performance?
Based on the provided specifications, the i-PRO WV-X4573LM has a significant low-light advantage: its minimum illumination is rated at 0.02 lx color / 0.003 lx B/W, compared to 0.10 lx listed for the Pelco SRXF3-12360-ES. The i-PRO also specifies on-board IR LEDs with a 10 m maximum irradiation distance; the Pelco lists IR and Day/Night capability but does not provide an IR range distance in the available spec data.
Can I power either camera from a standard 802.3af PoE switch?
Only the i-PRO WV-X4573LM is specified for standard 802.3af PoE at 13W, which falls within the 15.4W budget of a standard PoE switch port. The Pelco SRXF3-12360-ES requires PoE+ (802.3at), which demands a PoE+-capable switch port. If your existing infrastructure is limited to 802.3af, the i-PRO is the compatible option without switch upgrades.
Which camera is better suited for extreme cold environments?
The Pelco SRXF3-12360-ES specifies an operating temperature range of -40°C to +60°C, making it explicitly rated for severe cold-weather deployments. No operating temperature range is listed in the available specifications for the i-PRO WV-X4573LM, so a direct cold-temperature comparison cannot be made from the provided spec data. Installers specifying for sub-zero environments should verify the i-PRO's cold-temperature rating directly with i-PRO before selection.
