Pelco SRXE4-2V12-EBT-IR1 vs Pelco SRXE4-4V9-EBT-IR1: Specification Comparison
Both the Pelco SRXE4-2V12-EBT-IR1 and the SRXE4-4V9-EBT-IR1 are 4MP outdoor bullet cameras from the Sarix Enhanced 4 Series, targeted at perimeter and fixed-scene surveillance. They share a common platform—same sensor class, same lens range, same compression stack—making them direct cross-shop candidates for integrators specifying IP bullet cameras. The comparison below examines where the two models diverge across imaging, installation, and integration criteria, drawing exclusively from the provided specifications.

How do the imaging specs compare?
Both cameras share a 1/1.8-inch progressive-scan CMOS sensor, a 2560×1440 (4MP) maximum resolution at 60 fps, and a 4.4–9.3 mm motorized varifocal lens covering a 32–109° HFOV. WDR is rated identically at 130 dB SureVision, minimum color illumination is 0.003 lux on both, and both reach 0 lux with 850 nm IR illumination. On these core imaging parameters the two models are spec-identical per the provided data.
One notable discrepancy exists in the sensor size field: both products list '1/1.8 inch progressive scan CMOS' as the primary Sensor Type, yet both also carry a secondary field listing '1/2.8" CMOS' under Image Sensor Size. This internal inconsistency appears in the supplied specifications for both models equally and cannot be resolved without manufacturer clarification. Product B additionally lists a separate Lens Focal Length field of '2.8–12 mm,' which conflicts with the shared '4.4–9.3 mm' motorized varifocal spec; that field appears to be a data entry artifact rather than a confirmed optical difference.
What about installation and environment?
Ingress protection is identical on both: IP66, IP67, IP68 (2 m for 2 hours), IPX9K, and NEMA 4X. Both are rated IK11 for impact resistance at the camera level, although both also carry an IK09 Vandal Rating field—an internal inconsistency present in both spec sets. Operating temperature is -50°C to +65°C on both, noted as requiring PoE+ or external power at the extremes. Product B adds a secondary NEMA Rating field citing 'TS2 Sec 2.2.7–2.2.9, IK10,' which conflicts with the primary IK11 rating and cannot be resolved from the provided data alone.
Power input shows a divergence in labeling: Product A lists PoE Class 3 (802.3af, max 15.4 W), while Product B lists PoE+ (802.3at) in a dedicated field and also references '12/24 Vdc' as an alternative in its enrichment data—neither of which appears in Product A's specs. Product B also lists physical dimensions (309 mm × 133 mm × 133 mm) and mount types (wall, pole, corner), data absent from Product A's provided specifications. Both units share white housing and an outdoor environment rating.
Which fits your VMS and analytics better?
ONVIF compliance is identical: both carry Profile S, Profile T, Profile G, and Profile M, ensuring broad VMS compatibility. 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. Both are NDAA Section 889 and TAA compliant, and both carry the same cybersecurity stack—FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X.
On-board storage via microSD is specified for both. Product B's supplied specs include an Audio field noting 'Microphone supported' and a Memory field listing '4 GB RAM, 4 GB Flash,' neither of which is present in Product A's provided specifications. Video compression options are listed as H.265, H.264, and Motion JPEG on both, with Product B additionally referencing Pelco Smart Compression technology and an idle scene mode in its Bandwidth field. Both carry a 5-year warranty.
Which should you choose: the SRXE4-2V12-EBT-IR1 or the SRXE4-4V9-EBT-IR1?
Our take: The SRXE4-4V9-EBT-IR1 is the stronger documented choice when physical mounting flexibility, explicit PoE+ power budget, and on-board audio capability are decision criteria—though buyers should confirm these against the official datasheet, as the underlying spec sheets show significant overlap. Concretely: Product B specifies PoE+ (802.3at) where Product A lists only PoE Class 3 (802.3af), which matters for long cable runs or when powering supplemental accessories; Product B includes microphone support and 4 GB RAM / 4 GB Flash on-board compute not listed for Product A; and Product B provides physical dimensions (309 × 133 × 133 mm) and explicit mount-type options (wall, pole, corner) absent from Product A's specs. Where the specs are identical—4MP at 60 fps, 130 dB WDR, 0 lux IR, IP68 / IK11, FIPS 140-3 Level 3, full ONVIF suite, 5-year warranty—neither model holds an advantage. Verify conflicting internal fields (IK10 vs IK11, 1/1.8" vs 1/2.8" sensor, 4.4–9.3 mm vs 2.8–12 mm lens) against Pelco's official datasheets before specifying.

Frequently Asked Questions
Which should you choose: the SRXE4-2V12-EBT-IR1 or the SRXE4-4V9-EBT-IR1?
The SRXE4-4V9-EBT-IR1 is the stronger documented choice when physical mounting flexibility, explicit PoE+ power budget, and on-board audio capability are decision criteria—though buyers should confirm these against the official datasheet, as the underlying spec sheets show significant overlap. Concretely: Product B specifies PoE+ (802.3at) where Product A lists only PoE Class 3 (802.3af), which matters for long cable runs or when powering supplemental accessories; Product B includes microphone support and 4 GB RAM / 4 GB Flash on-board compute not listed for Product A; and Product B provides physical dimensions (309 × 133 × 133 mm) and explicit mount-type options (wall, pole, corner) absent from Product A's specs. Where the specs are identical—4MP at 60 fps, 130 dB WDR, 0 lux IR, IP68 / IK11, FIPS 140-3 Level 3, full ONVIF suite, 5-year warranty—neither model holds an advantage. Verify conflicting internal fields (IK10 vs IK11, 1/1.8" vs 1/2.8" sensor, 4.4–9.3 mm vs 2.8–12 mm lens) against Pelco's official datasheets before specifying.
Is the SRXE4-2V12-EBT-IR1 or the SRXE4-4V9-EBT-IR1 better for low-light performance?
Based on the provided specifications, low-light performance is identical on both models: 0.003 lux minimum color illumination and 0 lux with 850 nm IR illumination. Neither model has a documented advantage in low-light sensitivity per the supplied specs.
Can both cameras be powered by a standard 802.3af PoE switch?
Product A is listed at PoE Class 3, which is within the 802.3af (15.4 W) envelope. Product B is listed as PoE+ (802.3at, up to 30 W), suggesting it may require an 802.3at switch for full-feature operation—particularly at temperature extremes where additional power is noted. Confirm with Pelco's official datasheet before switch selection.
Do both cameras support the same VMS platforms?
Yes, per the provided specs. Both carry ONVIF Profile S, T, G, and M compliance, meaning they are compatible with any ONVIF-conformant VMS. Both are also NDAA Section 889 and TAA compliant, qualifying them for federal and government deployments.
