Pelco SRXE4-2X33-EBT-IR1 vs Pelco SRXE4-4V9-EBT-IR1: Specification Comparison
Both the Pelco SRXE4-2X33-EBT-IR1 and SRXE4-4V9-EBT-IR1 belong to the Sarix Enhanced 4 Series and are 4MP outdoor bullet cameras sharing a motorized varifocal lens, 60 fps capability, and identical ingress protection ratings. This comparison is intended for installers and IT buyers evaluating the two models side by side. Because the core imaging hardware is nearly identical across both SKUs, the meaningful differences lie in mounting options, certified approval listings, and a few datasheet-reported details that may affect deployment context.

How do the imaging specs compare?
Both cameras use a 1/1.8-inch progressive scan CMOS sensor delivering 2560 x 1440 (4MP) at up to 60 fps. Each model shares the same 4.4–9.3 mm motorized varifocal lens with a 32–109° HFOV, F1.4 aperture, 130 dB SureVision WDR, and a minimum illumination of 0.003 lux color / 0 lux IR. Video compression options are identical: H.265, H.264, and Motion JPEG. No spec distinction between the two models is present for sensor size, frame rate, WDR rating, or low-light threshold based on the provided data.
IR illumination on both is specified at 850 nm with 0 lux IR capability, indicating full IR cut-filter operation. The SRXE4-2X33-EBT-IR1 datasheet references an approximately 70 m IR range via a dedicated IR1 module callout; the SRXE4-4V9-EBT-IR1 specification does not state a numeric IR throw distance. Buyers requiring a confirmed IR range figure should note that only the SRXE4-2X33-EBT-IR1 provides this detail in the supplied specifications.
What about installation and environment?
Ingress protection is identical across both models: IP66, IP67, IP68 (2 m for 2 hr), IPX9K, and NEMA 4X. Both carry an IK11 impact rating and an operating temperature range of -50°C to +65°C with PoE+ or external power. Storage temperature is stated as -10°C to +70°C on both. Power input for both is PoE+ (802.3at), and both list PoE Class 3. The SRXE4-4V9-EBT-IR1 additionally notes compatibility with 12/24 Vdc external power in its marketing callout; the SRXE4-2X33-EBT-IR1 specification does not explicitly list a DC voltage alternative in the provided data.
Mounting options differ between the two models. The SRXE4-2X33-EBT-IR1 lists Wall, Pole, Corner, and Rack mount types. The SRXE4-4V9-EBT-IR1 lists Wall, Pole, and Corner only — Rack mount is not specified for it. Physical dimensions are only provided for the SRXE4-4V9-EBT-IR1: 309 mm x 133 mm x 133 mm (12.16" x 5.23" x 5.23"); the SRXE4-2X33-EBT-IR1 dimensions are not stated in the supplied specifications. Weight is not provided for either model. Certifications differ slightly: the SRXE4-2X33-EBT-IR1 lists UL, cUL, CE, RoHS, RCM, UKCA, NOM, KC, BIS, BSMI; the SRXE4-4V9-EBT-IR1 lists UL, cUL, CE, RoHS, RCM, UKCA, NOM, KC, BIS — BSMI certification is absent for the SRXE4-4V9-EBT-IR1 in the provided data.
Which fits your VMS and analytics better?
Both cameras carry identical ONVIF compliance: Profile S, Profile T, Profile G, and Profile M. Edge analytics are the same on both: Smart Analytics covering Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. On-board storage via microSD is supported on both. Audio input is described as microphone supported on both. Cybersecurity posture is identical: FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X. Both are NDAA Section 889 and TAA compliant, and both carry a 5-year warranty. No VMS-specific integrations beyond ONVIF are cited in the provided specifications for either model.
Which should you choose: the SRXE4-2X33-EBT-IR1 or the SRXE4-4V9-EBT-IR1?
Our take: The SRXE4-2X33-EBT-IR1 is the stronger choice when rack-mount deployment, BSMI certification for Taiwan-market compliance, or a confirmed 70 m IR throw distance are project requirements. Specifically: (1) the SRXE4-2X33-EBT-IR1 is the only model in the provided specs listing a Rack mount type, making it suitable for panel or enclosure mounting scenarios the SRXE4-4V9-EBT-IR1 does not cover; (2) BSMI approval appears only on the SRXE4-2X33-EBT-IR1, which matters for Taiwan-regulated deployments; (3) an IR range of approximately 70 m is documented only for the SRXE4-2X33-EBT-IR1 — the SRXE4-4V9-EBT-IR1 does not state a numeric figure in the supplied data. Where physical dimensions are needed for cutsheet or conduit planning, only the SRXE4-4V9-EBT-IR1 provides confirmed measurements (309 mm x 133 mm x 133 mm). For standard wall, pole, or corner outdoor bullet deployments with no regional BSMI or rack-mount requirement, both models are functionally equivalent across all other cited specifications.

Frequently Asked Questions
Which should you choose: the SRXE4-2X33-EBT-IR1 or the SRXE4-4V9-EBT-IR1?
The SRXE4-2X33-EBT-IR1 is the stronger choice when rack-mount deployment, BSMI certification for Taiwan-market compliance, or a confirmed 70 m IR throw distance are project requirements. Specifically: (1) the SRXE4-2X33-EBT-IR1 is the only model in the provided specs listing a Rack mount type, making it suitable for panel or enclosure mounting scenarios the SRXE4-4V9-EBT-IR1 does not cover; (2) BSMI approval appears only on the SRXE4-2X33-EBT-IR1, which matters for Taiwan-regulated deployments; (3) an IR range of approximately 70 m is documented only for the SRXE4-2X33-EBT-IR1 — the SRXE4-4V9-EBT-IR1 does not state a numeric figure in the supplied data. Where physical dimensions are needed for cutsheet or conduit planning, only the SRXE4-4V9-EBT-IR1 provides confirmed measurements (309 mm x 133 mm x 133 mm). For standard wall, pole, or corner outdoor bullet deployments with no regional BSMI or rack-mount requirement, both models are functionally equivalent across all other cited specifications.
Is the SRXE4-2X33-EBT-IR1 or SRXE4-4V9-EBT-IR1 better for low-light performance?
Based on the provided specifications, both cameras are identically rated for low-light performance: 0.003 lux color and 0 lux IR minimum illumination, with 850 nm IR illumination and 130 dB SureVision WDR on each. The SRXE4-2X33-EBT-IR1 datasheet cites an approximately 70 m IR throw range; no equivalent numeric distance is provided for the SRXE4-4V9-EBT-IR1 in the supplied specs. If confirmed IR range is a decision factor, the SRXE4-2X33-EBT-IR1 has the documented advantage.
Can either camera be powered by something other than PoE?
The SRXE4-4V9-EBT-IR1 marketing callout references compatibility with 12/24 Vdc external power in addition to PoE+ (802.3at). The SRXE4-2X33-EBT-IR1 provided specifications list PoE+ only and do not explicitly state a DC voltage input alternative. Installers requiring non-PoE power should verify with Pelco's datasheet directly for the SRXE4-2X33-EBT-IR1 before assuming PoE-only deployment.
Do both cameras support the same regional certifications and compliance marks?
Nearly, but not entirely. Both carry UL, cUL, CE, RoHS, RCM, UKCA, NOM, KC, and BIS certifications along with NDAA Section 889 and TAA compliance. The SRXE4-2X33-EBT-IR1 additionally lists BSMI certification, which is required for Taiwan-market deployments; BSMI does not appear in the SRXE4-4V9-EBT-IR1 certifications as provided. All other compliance marks are identical between the two models.
