Pelco SRXE4-2V12-EMD-1 vs Pelco SRXE4-4V29-EMD-IR1: Specification Comparison
Both the Pelco SRXE4-2V12-EMD-1 and SRXE4-4V29-EMD-IR1 are 4MP outdoor dome cameras from the Sarix Enhanced 4 Series, sharing the same sensor platform, lens assembly, and form factor. The primary differentiator between these two models is their low-light strategy: the -2V12-EMD-1 relies on a high-sensitivity color/B&W sensor, while the -4V29-EMD-IR1 integrates active IR illumination for true 0-lux operation. Installers evaluating these models are effectively choosing between passive low-light performance and active IR night vision.

How do the imaging specs compare?
Both cameras share identical core imaging hardware: a 1/1.8-inch progressive scan CMOS sensor, 2560x1440 maximum resolution at up to 60 fps, a 4.4–9.3 mm motorized varifocal lens covering 32–109° HFOV, F1.4 aperture, and 130 dB SureVision WDR. H.265, H.264, and Motion JPEG compression are supported on both models.
The decisive imaging difference is low-light capability. The SRXE4-2V12-EMD-1 achieves 0.003 lux in color mode and 0.001 lux in black-and-white mode using passive sensor sensitivity alone, with no IR illuminator listed. The SRXE4-4V29-EMD-IR1 also achieves 0.003 lux in color, but extends to 0 lux with active IR illumination at 850 nm — enabling operation in total darkness. The IR model's B&W floor is listed as 0 lux IR rather than the 0.001 lux B&W figure provided for the non-IR variant.
What about installation and environment?
Environmental and mechanical specs are identical across both models. Both carry IP66, IP67, IP68 (2 m for 2 hr), IPX9K, and NEMA 4X ingress ratings, IK11 impact resistance, and an operating temperature range of -50°C to +65°C when powered via PoE+ or external supply. Both are white dome housings with identical stated dimensions: 182 mm × 132 mm (base), with larger pendant/recessed configurations also specified.
Power input is PoE+ (802.3at) on both units, listed as PoE Class 3. Supported mount types are identical: wall, ceiling, pole, pendant, corner, and recessed. On-board memory is specified as 4 GB RAM and 4 GB Flash on both, with microSD listed for edge storage on both models.
Which fits your VMS and analytics better?
ONVIF compliance is identical: both models support Profile S, Profile T, Profile G, and Profile M. The analytics suite is also identical on both: Smart Analytics covering Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. Audio input (microphone supported) is listed for both. Cybersecurity credentials are identical — FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X — as are compliance approvals: NDAA Section 889 and TAA. Both carry a 5-year warranty and identical certifications including UL, cUL, CE, RoHS, RCM, UKCA, NOM, KC, and BIS.
Which should you choose: the SRXE4-2V12-EMD-1 or the SRXE4-4V29-EMD-IR1?
Our take: The SRXE4-4V29-EMD-IR1 is the stronger choice when the deployment environment includes periods of complete darkness or minimal ambient light, because its integrated 850 nm IR illuminator enables true 0-lux operation versus the SRXE4-2V12-EMD-1's 0.001-lux B&W floor under passive sensitivity alone. In all other measured specifications — sensor size, resolution, frame rate, WDR, lens, IP/IK ratings, operating temperature, PoE class, analytics, ONVIF profiles, and cybersecurity certifications — the two cameras are spec-for-spec identical. The SRXE4-2V12-EMD-1 is a reasonable alternative for sites with consistent ambient or supplemental lighting where the 0.001 lux passive B&W floor is sufficient and the absence of an IR illuminator reduces potential IR wash-out on nearby surfaces. Both models are equally suited to TAA/NDAA-compliant government deployments and environments requiring FIPS 140-3 Level 3 credential management.

Frequently Asked Questions
Which should you choose: the SRXE4-2V12-EMD-1 or the SRXE4-4V29-EMD-IR1?
The SRXE4-4V29-EMD-IR1 is the stronger choice when the deployment environment includes periods of complete darkness or minimal ambient light, because its integrated 850 nm IR illuminator enables true 0-lux operation versus the SRXE4-2V12-EMD-1's 0.001-lux B&W floor under passive sensitivity alone. In all other measured specifications — sensor size, resolution, frame rate, WDR, lens, IP/IK ratings, operating temperature, PoE class, analytics, ONVIF profiles, and cybersecurity certifications — the two cameras are spec-for-spec identical. The SRXE4-2V12-EMD-1 is a reasonable alternative for sites with consistent ambient or supplemental lighting where the 0.001 lux passive B&W floor is sufficient and the absence of an IR illuminator reduces potential IR wash-out on nearby surfaces.

Is the SRXE4-2V12-EMD-1 or SRXE4-4V29-EMD-IR1 better for low light?
The SRXE4-4V29-EMD-IR1 is better for low-light or zero-light conditions. Its integrated 850 nm IR illuminator brings minimum illumination to 0 lux with IR active. The SRXE4-2V12-EMD-1 reaches 0.001 lux in B&W mode using passive sensor sensitivity but has no IR illuminator listed in its specifications, making it less suitable for scenes with no ambient light at all.
Do both cameras support the same analytics?
Yes. Both the SRXE4-2V12-EMD-1 and SRXE4-4V29-EMD-IR1 are specified with identical Smart Analytics: Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. There is no analytics differentiation between the two models based on the provided specifications.
Are both cameras TAA and NDAA compliant?
Yes. Both models list NDAA Section 889 compliance and TAA compliance in their approvals, along with identical cybersecurity credentials including FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X. Both also carry a 5-year warranty. There is no compliance or security differentiation between the two models per the provided specifications.
