Pelco SRXE4-2V12-EBT-IR1 vs Pelco SRXE4-2X33-EBT-IR1: Specification Comparison
Both the Pelco SRXE4-2V12-EBT-IR1 and SRXE4-2X33-EBT-IR1 are 4MP outdoor bullet cameras from the Sarix Enhanced 4 Series, sharing the same resolution class, form factor, and general feature set. A buyer selecting between them is comparing two fixed cameras with integrated IR illumination and motorized varifocal lenses aimed at perimeter and outdoor surveillance. The key differences surfaced in the provided specifications center on minimum illumination figures, PoE class designation, and certain supplementary certifications and electrical ratings—worth examining closely before specifying either unit.
In This Guide
How do the imaging specs compare?
Both cameras share a 4MP (2560×1440) 1/1.8-inch progressive scan CMOS sensor with a maximum frame rate of 60 fps, a motorized varifocal lens at 4.4–9.3 mm, and an HFOV of 32–109 degrees. WDR is rated at 130 dB SureVision on both models, and both support H.265, H.264, and Motion JPEG compression. The aperture is F1.4 on both units per the provided specifications.
The minimum illumination figures diverge in the product data: the SRXE4-2V12-EBT-IR1 is specified at 0.003 lux color / 0 lux IR, while the SRXE4-2X33-EBT-IR1 datasheet entry includes an additional figure of 0.001 lux mono / 0 lux with IR. Both list integrated 850nm IR illumination with approximately 70 m range. The SRXE4-2X33-EBT-IR1 also lists a secondary focal length range of 2.8–12 mm under a separate spec field, which conflicts with the shared 4.4–9.3 mm primary lens spec; buyers should verify the correct lens specification against the product datasheet before ordering.
What about installation and environment?
Both cameras carry identical ingress protection ratings of IP66, IP67, IP68 (2 m for 2 hours), IPX9K, and NEMA 4X, and share an IK11 impact rating. Operating temperature is specified as -50°C to +65°C (with PoE+ or external power) on both units. Both are rated for outdoor deployment. The SRXE4-2X33-EBT-IR1 lists additional certifications of UL, cUL, CE, RoHS, RCM, UKCA, NOM, KC, BIS, and BSMI, as well as a NEMA TS2 Sec 2.2.7–2.2.9 and IK10 rating in a separate spec field; these supplementary certifications are not listed in the provided data for the SRXE4-2V12-EBT-IR1.
Power input differs between the two models as documented: the SRXE4-2V12-EBT-IR1 is listed as PoE Class 3 (802.3af), while the SRXE4-2X33-EBT-IR1 is listed as PoE+ (802.3at). This distinction has direct infrastructure implications—PoE+ requires a switch port capable of delivering up to 30 W, whereas Class 3 PoE requires only up to 15.4 W. Both list mounting options of wall and pole; the SRXE4-2X33-EBT-IR1 additionally lists corner and rack mount in its spec data. Dimensions and weight are not provided for either model.
Which fits your VMS and analytics better?
Both cameras offer identical ONVIF compliance: Profile S, Profile T, Profile G, and Profile M. The analytics suite is the same on both: Smart Analytics including Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert. On-board storage via microSD is supported on both. Cybersecurity features are identical across both models: FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, and 802.1X. Both carry NDAA Section 889 and TAA compliance.
Audio capability is noted explicitly for the SRXE4-2X33-EBT-IR1 as 'Microphone supported'; the SRXE4-2V12-EBT-IR1 lists 'Audio Analytics' as part of its analytics package but does not separately enumerate microphone hardware in the provided spec fields. The SRXE4-2X33-EBT-IR1 also lists 4 GB RAM and 4 GB Flash under a memory spec field; equivalent memory specifications are not present in the SRXE4-2V12-EBT-IR1 data. Both carry a 5-year warranty and connect via RJ-45 (listed for SRXE4-2X33-EBT-IR1; Ethernet listed for SRXE4-2V12-EBT-IR1).
Which should you choose: the SRXE4-2V12-EBT-IR1 or the SRXE4-2X33-EBT-IR1?
Our take: The SRXE4-2X33-EBT-IR1 is the stronger choice when the installation requires PoE+ infrastructure, broader international certifications, or explicit microphone hardware confirmation. Per the provided specifications, the SRXE4-2X33-EBT-IR1 is rated for PoE+ (802.3at) versus PoE Class 3 on the SRXE4-2V12-EBT-IR1—a meaningful difference for switch port planning and power budgeting. The SRXE4-2X33-EBT-IR1 also documents a lower minimum illumination figure (0.001 lux mono vs. 0.003 lux color) and adds a broader certification list including UL, CE, RoHS, and UKCA not enumerated in the SRXE4-2V12-EBT-IR1 data. However, both models are otherwise functionally equivalent on sensor size, resolution, WDR, lens range, IR distance, analytics, ONVIF profiles, cybersecurity posture, ingress protection, operating temperature, and warranty. Buyers whose switch infrastructure is limited to 802.3af and who do not require the extended international certifications may find the SRXE4-2V12-EBT-IR1 sufficient; confirm the correct lens specification (4.4–9.3 mm vs. the conflicting 2.8–12 mm field) with Pelco before finalizing either order.

Frequently Asked Questions
Which should you choose: the SRXE4-2V12-EBT-IR1 or the SRXE4-2X33-EBT-IR1?
The SRXE4-2X33-EBT-IR1 is the stronger choice when the installation requires PoE+ infrastructure, broader international certifications, or explicit microphone hardware confirmation. Per the provided specifications, the SRXE4-2X33-EBT-IR1 is rated for PoE+ (802.3at) versus PoE Class 3 on the SRXE4-2V12-EBT-IR1—a meaningful difference for switch port planning and power budgeting. The SRXE4-2X33-EBT-IR1 also documents a lower minimum illumination figure (0.001 lux mono vs. 0.003 lux color) and adds a broader certification list including UL, CE, RoHS, and UKCA not enumerated in the SRXE4-2V12-EBT-IR1 data. However, both models are otherwise functionally equivalent on sensor size, resolution, WDR, lens range, IR distance, analytics, ONVIF profiles, cybersecurity posture, ingress protection, operating temperature, and warranty. Buyers whose switch infrastructure is limited to 802.3af and who do not require the extended international certifications may find the SRXE4-2V12-EBT-IR1 sufficient; confirm the correct lens specification (4.4–9.3 mm vs. the conflicting 2.8–12 mm field) with Pelco before finalizing either order.
Is the SRXE4-2V12-EBT-IR1 or SRXE4-2X33-EBT-IR1 better for low light?
Based on the provided specifications, the SRXE4-2X33-EBT-IR1 lists a lower minimum illumination of 0.001 lux mono / 0 lux with IR, compared to 0.003 lux color / 0 lux IR on the SRXE4-2V12-EBT-IR1. Both deliver 0 lux performance with their integrated 850 nm IR illuminators at approximately 70 m range, so the practical difference in full IR mode is not spec-documented. Verify the mono vs. color sensitivity distinction against the official datasheets.
Can I power either camera from a standard 802.3af PoE switch?
The SRXE4-2V12-EBT-IR1 is specified at PoE Class 3, which is compatible with standard 802.3af switches (up to 15.4 W per port). The SRXE4-2X33-EBT-IR1 is specified as PoE+ (802.3at), which requires a switch port capable of delivering up to 30 W. Using an 802.3af-only switch with the SRXE4-2X33-EBT-IR1 may result in reduced functionality or failure to power on; confirm power requirements with Pelco before installation.
Do both cameras support the same analytics and ONVIF profiles?
Yes, per the provided specifications, both cameras support identical analytics—Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert—and the same four ONVIF profiles: Profile S, Profile T, Profile G, and Profile M. Both also share the same cybersecurity stack (FIPS 140-3 Level 3, TPM, Secure Boot, HTTPS, 802.1X) and carry NDAA Section 889 and TAA compliance, making them equivalent for VMS integration and federal procurement eligibility.
