Pelco SRXP4-2V10-IMD vs Pelco SRXP4-3V10-IMD: Specification Comparison
Both the Pelco SRXP4-2V10-IMD and SRXP4-3V10-IMD belong to the Sarix Professional 4 Series and are 2MP (1920×1080) indoor fixed dome cameras sharing the same IK09 vandal rating, PoE Class 3 power, ONVIF Profile S/T/G/M compliance, and 1/2.8-inch progressive scan CMOS sensor. The comparison centers on meaningful differences in lens range, WDR performance, low-light sensitivity, and on-camera analytics capability—factors that will drive the selection decision for integrators specifying indoor surveillance deployments.

How do the imaging specs compare?
Both cameras share a 1/2.8-inch progressive scan CMOS sensor at 2MP (1920×1080) with a maximum frame rate of 60 fps and H.264/H.265/Smart Compression video encoding. The SRXP4-2V10-IMD offers a wider motorized varifocal lens range of 3.4–10.5 mm, delivering a horizontal field of view from 101° down to 31°. The SRXP4-3V10-IMD uses a narrower 4.4–9.3 mm motorized varifocal lens, covering 32–109° HFOV. Both support remote zoom and autofocus, but the -2V10 provides greater flexibility at the wide end for open-space coverage.
On dynamic range, the SRXP4-3V10-IMD holds an advantage with 130 dB SureVision WDR versus the SRXP4-2V10-IMD's 126 dB (WDR on). In low-light performance, the SRXP4-3V10-IMD reaches 0.003 lux monochrome minimum illumination, compared to 0.005 lux monochrome for the SRXP4-2V10-IMD; both are rated at 0.01 lux color. The -2V10-IMD specifies a signal-to-noise ratio greater than 50 dB, 3D noise reduction, P-Iris control, and a 83 dB WDR-off dynamic range—these parameters are not stated in the -3V10-IMD specification sheet.
What about installation and environment?
Both cameras are rated for indoor use, share IK09 vandal impact resistance, and are powered via PoE Class 3. Both use an RJ45 connector over CAT5 or higher cabling and share a white dome housing. IP66 is referenced in the SRXP4-2V10-IMD specs; the SRXP4-3V10-IMD spec sheet lists IP66 in the product data as well. Storage temperature for the SRXP4-3V10-IMD is specified as -10°C to +70°C (14°F to 158°F); an equivalent operating or storage temperature range is not stated in the SRXP4-2V10-IMD specification data provided. The SRXP4-2V10-IMD lists wall, ceiling, pole, pendant, and corner mount types; the SRXP4-3V10-IMD lists wall, ceiling, and pendant. Both cameras support image rotation including 90°/180°/270° and corridor mode per the -2V10-IMD spec; this is not explicitly listed for the -3V10-IMD.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile S, T, G, and M compliant and support IPv4, IPv6, HTTP, HTTPS, DNS, NTP, RTSP, RTP, TCP, UDP, and DHCP. Both provide microSD/SDHC/SDXC onboard storage up to 1.5 TB per the SRXP4-2V10-IMD spec; the SRXP4-3V10-IMD lists microSD support without specifying a maximum capacity in the provided data. Both carry 1 GB RAM and 512 MB Flash. The SRXP4-2V10-IMD specifies audio as G.711 PCM 8 kHz and Opus with line-level I/O, plus alarm in/alarm out external I/O and a USB 2.0 port. The SRXP4-3V10-IMD notes microphone support but does not specify audio codec or I/O type in the provided specs.
On analytics, the SRXP4-3V10-IMD specifies a substantially richer on-camera Smart Analytics suite: Person/Vehicle Detection, Directional Violation, Loitering, Beam Crossing, Crowd Detection, and Tamper Alert. The SRXP4-2V10-IMD lists Pixel Motion Detection and Classified Object Detection only. Integrators deploying rule-based behavioral analytics at the edge without a dedicated VMS analytics license will find the -3V10-IMD the more capable platform. The SRXP4-2V10-IMD is the appropriate choice when analytics processing is handled by the VMS and the priority is broad lens coverage or line-level audio I/O.
Which should you choose: the SRXP4-2V10-IMD or the SRXP4-3V10-IMD?
Our take: The SRXP4-3V10-IMD is the stronger choice when on-camera behavioral analytics, marginally better low-light performance, and higher WDR headroom are the primary requirements. It delivers 130 dB SureVision WDR versus 126 dB on the -2V10-IMD, reaches 0.003 lux monochrome versus 0.005 lux, and includes a six-rule Smart Analytics engine—Person/Vehicle Detection, Directional Violation, Loitering, Beam Crossing, Crowd Detection, and Tamper Alert—where the -2V10-IMD offers only Pixel Motion and Classified Object Detection. Conversely, the SRXP4-2V10-IMD is the correct pick when a wider lens range is needed (3.4–10.5 mm versus 4.4–9.3 mm, yielding up to 101° HFOV versus 109° on the -3V10-IMD at wide end per respective specs), when line-level audio I/O or alarm I/O is required at the camera, or when the VMS will provide analytics and edge cost must be minimized. Both cameras are rated PoE Class 3, IK09, and ONVIF Profile S/T/G/M.

Frequently Asked Questions
Which should you choose: the SRXP4-2V10-IMD or the SRXP4-3V10-IMD?
The SRXP4-3V10-IMD is the stronger choice when on-camera behavioral analytics, marginally better low-light performance, and higher WDR headroom are the primary requirements. It delivers 130 dB SureVision WDR versus 126 dB on the -2V10-IMD, reaches 0.003 lux monochrome versus 0.005 lux, and includes a six-rule Smart Analytics engine—Person/Vehicle Detection, Directional Violation, Loitering, Beam Crossing, Crowd Detection, and Tamper Alert—where the -2V10-IMD offers only Pixel Motion and Classified Object Detection. Conversely, the SRXP4-2V10-IMD is the correct pick when a wider lens range is needed (3.4–10.5 mm versus 4.4–9.3 mm, yielding up to 101° HFOV versus 109° on the -3V10-IMD at wide end per respective specs), when line-level audio I/O or alarm I/O is required at the camera, or when the VMS will provide analytics and edge cost must be minimized. Both cameras are rated PoE Class 3, IK09, and ONVIF Profile S/T/G/M.
Is the SRXP4-2V10-IMD or SRXP4-3V10-IMD better for low-light corridors?
The SRXP4-3V10-IMD has a slight edge in low light: its specified monochrome minimum illumination is 0.003 lux versus 0.005 lux for the SRXP4-2V10-IMD, both measured under comparable conditions. Color minimum illumination is 0.01 lux for both models. The -3V10-IMD also carries a higher WDR rating (130 dB SureVision versus 126 dB), which helps in high-contrast lobby or entrance lighting conditions.
Does either camera support on-camera analytics without a VMS license?
Yes—the SRXP4-3V10-IMD includes a specified on-camera Smart Analytics suite covering Person/Vehicle Detection, Directional Violation, Loitering, Beam Crossing, Crowd Detection, and Tamper Alert, which run at the edge without requiring a VMS analytics license. The SRXP4-2V10-IMD specifies only Pixel Motion Detection and Classified Object Detection on-camera; more advanced rule-based analytics would need to be handled by the connected VMS.
Which model gives a wider field of view for open areas?
The SRXP4-2V10-IMD provides a wider field of view at the broad end of its zoom range: its 3.4–10.5 mm motorized varifocal lens covers 101° horizontal at the wide end. The SRXP4-3V10-IMD uses a 4.4–9.3 mm lens rated at up to 109° HFOV per its spec sheet. Note that the SRXP4-2V10-IMD's wider focal-length range (3.4 mm start versus 4.4 mm) provides greater flexibility for both wide-area and zoomed-in coverage in a single lens, which is an advantage in variable-layout environments.
