Pelco SRXE4-2V12-EMD-IR1 vs Pelco SRXE4-6V9-EMD-1: Specification Comparison
Both the Pelco SRXE4-2V12-EMD-IR1 and the SRXE4-6V9-EMD-1 are 4MP outdoor dome cameras from the Sarix Enhanced 4 Series, sharing the same 1/1.8-inch progressive scan CMOS sensor, identical 4.4–9.3 mm motorized varifocal lens, and the same NDAA/TAA compliance posture. The key differentiator between these two models is infrared illumination: the SRXE4-2V12-EMD-IR1 carries a built-in 850 nm IR emitter enabling operation at 0 Lux, while the SRXE4-6V9-EMD-1 has no stated IR capability and bottoms out at 0.001 lux monochrome.

How do the imaging specs compare?
Both cameras share an identical imaging foundation: a 1/1.8-inch progressive scan CMOS sensor, 2560×1440 (4MP) maximum resolution, 60 fps maximum frame rate, and 130 dB SureVision WDR. The F1.4 aperture and 4.4–9.3 mm motorized varifocal lens providing 32–109° HFOV are likewise identical across both models, so daytime and high-contrast imaging performance is effectively equivalent.
Low-light performance is where the two diverge. The SRXE4-2V12-EMD-IR1 integrates an 850 nm IR illuminator and achieves 0 Lux minimum illumination in IR mode (with 0.003 Lux color sensitivity), making it capable of imaging in complete darkness. The SRXE4-6V9-EMD-1 specs state 0.003 Lux color and 0.001 Lux monochrome minimum illumination but list no IR illuminator and no 0 Lux capability. The IR model's specs note 0.001 Lux mono sensitivity as well, but the critical differentiator is the active IR emitter enabling true zero-lux operation on the -IR1 variant.
What about installation and environment?
Environmental and mechanical specs are identical for both models. Both carry IP66, IP67, IP68 (2 m for 2 hr), IPX9K, and NEMA 4X ingress protection, along with an IK11 impact rating and an IK09 vandal rating. The operating temperature range of −50°C to +65°C (with PoE+ or external power) applies equally to both, making either unit suitable for extreme cold-weather deployments.
Power requirements are the same: both are PoE Class 3 units supporting PoE+ (802.3at). Both share identical RJ-45 connectivity and the same published physical dimensions of 182×132 mm (DxH) in standard configuration. Mounting options — wall, ceiling, pole, pendant, corner, and recessed — are identical per the specs provided. No weight data is specified for either model.
Which fits your VMS and analytics better?
Both cameras are identical in VMS and protocol integration: ONVIF Profile S, T, G, and M compliance is present on both, ensuring broad compatibility with third-party video management systems. Cybersecurity credentials are also shared — FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X — along with H.265, H.264, and Motion JPEG compression and Pelco Smart Compression technology for bandwidth management.
Edge analytics and audio capabilities are specified as identical: both models include Smart Analytics covering Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. Both support a microphone and provide microSD edge storage. No difference in on-board memory (4 GB RAM, 4 GB Flash), certifications (UL, cUL, CE, RoHS, RCM, UKCA, NOM, KC, BIS), or warranty (5-year) is indicated in the provided specifications.
Which should you choose: the SRXE4-2V12-EMD-IR1 or the SRXE4-6V9-EMD-1?
Our take: The SRXE4-2V12-EMD-IR1 is the stronger choice when the deployment site experiences periods of complete or near-complete darkness and no supplemental lighting is available. The sole documented differentiator between these two cameras is IR illumination: the -IR1 variant carries an integrated 850 nm IR emitter that drives minimum illumination to 0 Lux, versus the SRXE4-6V9-EMD-1's floor of 0.001 Lux monochrome with no IR emitter specified. Every other spec — sensor, lens, WDR (130 dB), frame rate (60 fps), ingress protection (IP66/67/68/IPX9K/NEMA 4X), impact rating (IK11), operating temperature (−50°C to +65°C), PoE class, analytics suite, ONVIF profiles, cybersecurity posture, and warranty — is identical per the provided data. Choose the SRXE4-6V9-EMD-1 only if the site has adequate ambient or supplemental lighting and you want to avoid the added draw of an active IR emitter.

Frequently Asked Questions
Which should you choose: the SRXE4-2V12-EMD-IR1 or the SRXE4-6V9-EMD-1?
The SRXE4-2V12-EMD-IR1 is the stronger choice when the deployment site experiences periods of complete or near-complete darkness and no supplemental lighting is available. The sole documented differentiator between these two cameras is IR illumination: the -IR1 variant carries an integrated 850 nm IR emitter that drives minimum illumination to 0 Lux, versus the SRXE4-6V9-EMD-1's floor of 0.001 Lux monochrome with no IR emitter specified. Every other spec — sensor, lens, WDR (130 dB), frame rate (60 fps), ingress protection (IP66/67/68/IPX9K/NEMA 4X), impact rating (IK11), operating temperature (−50°C to +65°C), PoE class, analytics suite, ONVIF profiles, cybersecurity posture, and warranty — is identical per the provided data. Choose the SRXE4-6V9-EMD-1 only if the site has adequate ambient or supplemental lighting and you want to avoid the added draw of an active IR emitter.
Is the SRXE4-2V12-EMD-IR1 or SRXE4-6V9-EMD-1 better for low-light or no-light conditions?
The SRXE4-2V12-EMD-IR1 is better for low-light and no-light conditions. Its integrated 850 nm IR illuminator enables 0 Lux minimum illumination, meaning it can produce usable images in complete darkness. The SRXE4-6V9-EMD-1 bottoms out at 0.001 Lux monochrome and has no IR illuminator specified, so it requires some ambient light to function.
Do these two cameras have different ONVIF profiles or VMS compatibility?
No. Both cameras support identical ONVIF profiles — Profile S, Profile T, Profile G, and Profile M — per the provided specifications. VMS integration requirements and cybersecurity credentials (FIPS 140-3 Level 3, TPM, Secure Boot, 802.1X) are also identical, so neither model offers an advantage in VMS or network security integration.
Can either camera handle extreme cold-weather or harsh outdoor environments?
Yes, both cameras are rated identically for harsh environments: IP66, IP67, IP68 (2 m for 2 hr), IPX9K, NEMA 4X, IK11 impact resistance, and an operating temperature range of −50°C to +65°C (with PoE+ or external power). Neither model has an environmental advantage over the other based on the provided specifications.
