Pelco SRXE4-2V12-EMD-1 vs Pelco SRXE4P-4V9-EMD-IR1: Specification Comparison
Both the Pelco SRXE4-2V12-EMD-1 and the SRXE4P-4V9-EMD-IR1 are 4MP outdoor dome cameras from the Sarix Enhanced 4 Series, sharing the same sensor class, resolution, and form factor. A buyer evaluating either unit is choosing between two FIPS 140-3 Level 3 cybersecurity-hardened fixed domes for demanding outdoor deployments. The primary differentiators are the illumination approach—passive low-light versus active IR—and minor lens configuration differences. Both carry NDAA Section 889 and TAA compliance, making them candidates for federal and government-regulated installations.

How do the imaging specs compare?
Both cameras share a 1/1.8-inch progressive scan CMOS sensor outputting 2560 x 1440 at up to 60 fps, with a 130 dB SureVision WDR rating and H.265 / H.264 / Motion JPEG compression. The SRXE4-2V12-EMD-1 uses a 4.4–9.3 mm motorized varifocal lens covering a 32–109° HFOV, and its minimum illumination is listed as 0.003 Lux color / 0.001 Lux B/W—the B/W figure indicating passive Day/Night switching capability without active IR.
The SRXE4P-4V9-EMD-IR1 carries the same 4.4–9.3 mm motorized varifocal lens and the same 32–109° HFOV. Its minimum illumination is listed as 0.003 Lux color / 0 Lux IR, and the product data references an IR1 module with approximately 70 m range at 850 nm, enabling true zero-lux operation when IR illumination is active. The SRXE4-2V12-EMD-1 datasheet does not specify an IR range or an active IR emitter; its 0.001 Lux B/W figure reflects passive sensitivity rather than IR-assisted night vision.
What about installation and environment?
Both cameras carry identical ingress and impact ratings: IP66, IP67, IP68 (2 m for 2 hr), IPX9K, and NEMA 4X, plus an IK11 impact rating. Both operate across the same temperature range of -50°C to +65°C with PoE+ or external power. Both are dome form-factor units with identical published dimensions of 182 mm × 132 mm (dome) or 219 mm × 198 mm (with shroud), and both support wall, ceiling, pole, pendant, corner, and recessed mounting configurations.
Power input for both is listed as PoE (Class 3) in the primary specs, with the SRXE4P-4V9-EMD-IR1 datasheet additionally noting 12/24 Vdc as an alternative power source. The SRXE4-2V12-EMD-1 spec data does not explicitly list 12/24 Vdc as an alternative—buyers requiring hardwired DC power should verify against the full Pelco datasheet for that model. Both units are white-housing outdoor domes.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile S, T, G, and M compliant, and both carry identical Smart Analytics feature sets: Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. Both support microphone input and microSD edge storage. Both use Pelco Smart Compression technology with an idle-scene mode for bandwidth management. From a VMS integration and analytics standpoint, no functional difference is evident in the provided specifications.
Both cameras share the same cybersecurity stack: FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X. Both carry NDAA Section 889 and TAA compliance. Certifications listed for both include UL, cUL, CE, RoHS, RCM, UKCA, NOM, KC, and BIS. Both carry a 5-year warranty. There is no specification difference in VMS compatibility, analytics capability, or compliance posture between the two models.
Which should you choose: the SRXE4-2V12-EMD-1 or the SRXE4P-4V9-EMD-IR1?
Our take: The SRXE4P-4V9-EMD-IR1 is the stronger choice when reliable zero-lux night imaging is required, because it incorporates an active IR1 module rated at approximately 70 m range at 850 nm, enabling 0 Lux IR minimum illumination versus the SRXE4-2V12-EMD-1's 0.001 Lux B/W passive sensitivity—a meaningful gap in unlit or intermittently lit environments. The SRXE4-2V12-EMD-1 does not specify an active IR emitter in the provided data, making it dependent on ambient light for low-light performance. Beyond illumination, the SRXE4P-4V9-EMD-IR1 also explicitly lists 12/24 Vdc as an alternative power source, while the SRXE4-2V12-EMD-1 spec data does not confirm this option. All other decision-relevant specifications—sensor, resolution, frame rate, WDR, lens, analytics, ONVIF profiles, IP/IK ratings, temperature range, cybersecurity, and compliance—are identical between the two models. Choose the SRXE4-2V12-EMD-1 only if ambient light conditions are adequate and an IR emitter is unnecessary.

Is the SRXE4-2V12-EMD-1 or SRXE4P-4V9-EMD-IR1 better for low-light or no-light conditions?
The SRXE4P-4V9-EMD-IR1 is better for low-light and zero-lux conditions. Its specs list an IR1 module with approximately 70 m range at 850 nm and a minimum illumination of 0 Lux IR. The SRXE4-2V12-EMD-1 achieves 0.001 Lux B/W through passive Day/Night switching; no active IR emitter is specified for that model in the provided data.
Do both cameras meet NDAA Section 889 and TAA requirements for government deployments?
Yes. Both the SRXE4-2V12-EMD-1 and the SRXE4P-4V9-EMD-IR1 are listed as NDAA Section 889 compliant and TAA compliant. Both also carry FIPS 140-3 Level 3 cybersecurity validation, TPM, and Secure Boot—specifications relevant to federal and regulated-sector procurement.
Can either camera be powered by 12 or 24 Vdc instead of PoE?
The SRXE4P-4V9-EMD-IR1 spec data explicitly lists PoE+ or 12/24 Vdc as power options. The SRXE4-2V12-EMD-1 spec data provided lists PoE (Class 3) as the power type without explicitly confirming 12/24 Vdc. Buyers requiring DC hardwire for the SRXE4-2V12-EMD-1 should verify against Pelco's full published datasheet.
