Pelco SRXE4-6V9-EMD-1 vs Pelco SRXE4P-4V9-EMD-IR1: Specification Comparison
Both the Pelco SRXE4-6V9-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 general form factor. A buyer evaluating either unit is choosing between two fixed-lens IP domes targeting hardened outdoor deployments with government-grade cybersecurity. The key differentiating factors are the low-light illumination approach — passive low-light on the -6V9 versus active 850 nm IR illumination on the -IR1 — and the inclusion of a discrete IR module on the -IR1 variant.

How do the imaging specs compare?
Both cameras share a 1/1.8-inch progressive scan CMOS sensor producing 2560 x 1440 (4MP) at up to 60 fps, with a 4.4–9.3 mm motorized varifocal lens covering 32–109° HFOV and an F1.4 aperture. WDR is identical at 130 dB SureVision on both units. Video compression options are also the same: H.265, H.264, and Motion JPEG.
Low-light performance is where the two diverge. The SRXE4-6V9-EMD-1 specifies a minimum illumination of 0.003 lux color and 0.001 lux monochrome (B/W), relying on the sensor's native sensitivity without active IR. The SRXE4P-4V9-EMD-IR1 specifies 0.003 lux color but lists 0 lux IR, indicating active 850 nm IR illumination — the product page cites an approximate 70 m IR range. The -6V9-EMD-1 does not have a specified IR illuminator range per the provided specs; monochrome sensitivity is listed at 0.001 lux B/W.
What about installation and environment?
Both units carry identical environmental ratings: IP66, IP67, IP68 (2 m for 2 hours), IPX9K, and NEMA 4X, with an IK11 impact rating and an operating temperature range of −50°C to +65°C when powered via PoE+ or external supply. Dome housing color is white on both. Both support the same mounting configurations — wall, ceiling, pole, pendant, corner, and recessed — and share identical physical dimensions: 182 mm × 132 mm (dome) or 219 mm × 198 mm (with surface mount base).
Power input is listed as PoE (PoE Class 3) for both units in the structured specs, with the product page for the -IR1 also noting 12/24 Vdc as an alternative input. The -6V9-EMD-1 structured specs do not explicitly list 12/24 Vdc as a power option. Installers requiring a non-PoE DC power feed should verify the -6V9-EMD-1 datasheet directly before specifying.
Which fits your VMS and analytics better?
Both cameras are ONVIF Profile S, T, G, and M compliant, ensuring broad VMS compatibility. Edge analytics are identical across both SKUs: Smart Analytics including Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. Audio input (microphone supported) and microSD edge storage are present on both. Memory is listed at 4 GB RAM and 4 GB Flash on both units.
Cybersecurity credentials are the same on both: FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X. Both carry NDAA Section 889 and TAA compliance. Neither unit presents a differentiator in VMS integration or analytics capability based on the provided specifications; selection between the two on these criteria should rest solely on low-light and illumination requirements.
Which should you choose: the SRXE4-6V9-EMD-1 or the SRXE4P-4V9-EMD-IR1?
Our take: The SRXE4P-4V9-EMD-IR1 is the stronger choice when the deployment site has periods of complete or near-zero ambient light and the 0 lux IR capability with approximately 70 m active illumination range is required. The SRXE4-6V9-EMD-1, by contrast, relies on passive sensor sensitivity down to 0.001 lux monochrome — adequate for scenes with residual ambient light but insufficient in true zero-light conditions. On every other measurable spec, the two cameras are identical: same 4MP 2560 x 1440 sensor, same 4.4–9.3 mm motorized varifocal lens, same 130 dB SureVision WDR, same IP66/67/68 and IK11 ratings, same −50°C to +65°C operating range, same FIPS 140-3 Level 3 cybersecurity, and the same five-year warranty. Specify the -IR1 for zero-ambient-light perimeter or parking applications; specify the -6V9 where some ambient light is always present and a discrete IR illuminator is undesirable.

Frequently Asked Questions
Which should you choose: the SRXE4-6V9-EMD-1 or the SRXE4P-4V9-EMD-IR1?
The SRXE4P-4V9-EMD-IR1 is the stronger choice when the deployment site has periods of complete or near-zero ambient light and the 0 lux IR capability with approximately 70 m active illumination range is required. The SRXE4-6V9-EMD-1, by contrast, relies on passive sensor sensitivity down to 0.001 lux monochrome — adequate for scenes with residual ambient light but insufficient in true zero-light conditions. On every other measurable spec, the two cameras are identical: same 4MP 2560 x 1440 sensor, same 4.4–9.3 mm motorized varifocal lens, same 130 dB SureVision WDR, same IP66/67/68 and IK11 ratings, same −50°C to +65°C operating range, same FIPS 140-3 Level 3 cybersecurity, and the same five-year warranty. Specify the -IR1 for zero-ambient-light perimeter or parking applications; specify the -6V9 where some ambient light is always present and a discrete IR illuminator is undesirable.
Is the SRXE4-6V9-EMD-1 or SRXE4P-4V9-EMD-IR1 better for low-light performance?
The SRXE4P-4V9-EMD-IR1 is better suited to zero-ambient-light conditions because it includes an active 850 nm IR illuminator rated at approximately 70 m range and lists 0 lux minimum illumination in IR mode. The SRXE4-6V9-EMD-1 achieves 0.001 lux monochrome sensitivity through sensor design alone, without an IR illuminator, making it suitable for low-light but not true zero-light environments.
Do both cameras meet federal procurement requirements like NDAA and TAA?
Yes. Both the SRXE4-6V9-EMD-1 and the SRXE4P-4V9-EMD-IR1 are listed as NDAA Section 889 compliant and TAA compliant in the provided specifications. Both also carry FIPS 140-3 Level 3, TPM, and Secure Boot cybersecurity credentials, which are commonly required in federal and DoD deployments.
Can both cameras be powered by PoE, and do they support auxiliary DC power?
Both cameras list PoE (Class 3) as their primary power input. The SRXE4P-4V9-EMD-IR1 product page also notes 12/24 Vdc as an alternative input. The provided specifications for the SRXE4-6V9-EMD-1 do not explicitly confirm 12/24 Vdc support; verify the published datasheet before designing a non-PoE installation around that model.
