i-PRO U1542LA vs Pelco SRXE4-2X33-EBT-IR1: Specification Comparison
Both the i-PRO WV-U1542LA and the Pelco SRXE4-2X33-EBT-IR1 are 4MP fixed outdoor bullet cameras designed for perimeter and area surveillance. This comparison examines how they differ across imaging capability, environmental ruggedness, power requirements, and platform integration — the factors that most influence specification and procurement decisions for installers and IT buyers evaluating outdoor fixed camera deployments.

How do the imaging specs compare?
The Pelco SRXE4-2X33-EBT-IR1 carries a larger 1/1.8-inch progressive-scan CMOS sensor versus the i-PRO WV-U1542LA's approximately 1/2.7-inch CMOS. That larger sensor directly enables the Pelco's superior low-light performance: 0.003 lux color and 0 lux with IR active, compared to the i-PRO's 0.3 lux color and 0.12 lux B&W. The Pelco also delivers 130 dB WDR via SureVision, while the i-PRO achieves a maximum 102 dB dynamic range with Super Dynamic enabled at level 31. Maximum frame rate favors the Pelco at 60 fps versus the i-PRO's 30 fps at 2688×1520.
On optics, the i-PRO uses a 2.9–7.3 mm motorized varifocal lens providing 44–103° horizontal field of view, with 2.5x optical zoom and extra optical zoom up to 3.3x at 1080p. The Pelco uses a 4.4–9.3 mm motorized varifocal covering 32–109° horizontal field of view — a narrower minimum angle but a wider maximum angle. The Pelco's specified IR illumination reaches approximately 70 m (per datasheet card), while the i-PRO's integrated IR LED is rated to 20 m. The Pelco's maximum aperture is F1.4; the i-PRO's is F2.0 (wide) to F3.0 (tele), further contributing to the low-light gap.
What about installation and environment?
The Pelco SRXE4-2X33-EBT-IR1 offers substantially broader environmental ratings: IP66, IP67, IP68 (2 m for 2 hours), and IPX9K, all with NEMA 4X, compared to the i-PRO WV-U1542LA's IP66 and NEMA 4X. Impact resistance also favors the Pelco at IK11 versus the i-PRO's IK10. Operating temperature range is wider on the Pelco at -50°C to +65°C (with PoE+ or external power) versus the i-PRO's -30°C to +50°C — a meaningful difference for extreme-climate deployments. The i-PRO additionally specifies wind resistance to 40 m/s (~89 mph) and an anti-condensation Temish element, neither of which appears in the Pelco's provided specs.
Power requirements differ: the i-PRO WV-U1542LA draws 7.2 W on PoE IEEE 802.3af (Class 0), which means standard 802.3af switches are sufficient. The Pelco SRXE4-2X33-EBT-IR1 requires PoE+ (802.3at, Class 3), demanding a PoE+ capable switch or injector at each drop — a switch-budget and cable-run consideration. The i-PRO weighs approximately 860 g; weight and dimensions for the Pelco are not provided in the supplied specifications. Both cameras are white-housing outdoor bullet form factors. The i-PRO specifies ceiling and wall mounting with defined pan/tilt/yaw ranges; the Pelco lists wall, pole, corner, and rack mounting.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profile S, T, and G. The Pelco SRXE4-2X33-EBT-IR1 additionally carries ONVIF Profile M, which adds metadata streaming for analytics interoperability. The Pelco's edge analytics are substantially broader: Person/Vehicle Detection, Direction Violation, Loitering, Beam Crossing, Crowd Detection, Audio Analytics, and Tamper Alert are listed. The i-PRO WV-U1542LA's specified analytics are Video Motion Detection (up to 4 areas) and Scene Change Detection (1 area). Both support microSD local storage; the i-PRO specifies up to 512 GB microSDXC.
On cybersecurity, the Pelco specifies FIPS 140-3 Level 3, TPM, and Secure Boot in addition to HTTPS and 802.1X — a significantly higher cryptographic assurance level. The i-PRO lists device certificate authentication, HTTPS, 802.1X, and SNMPv1/v2/v3 but does not claim FIPS 140-3 or TPM in the provided specs. Audio support differs: the i-PRO WV-U1542LA specifies an audio input but no compression or output in the provided specs (audio compression and transmission mode fields are blank); the Pelco notes microphone support. The i-PRO also specifies MQTT and LLDP protocol support and IPv6, and ships with an eight-language GUI. The Pelco carries NDAA Section 889 and TAA compliance; the i-PRO's provided specs do not state these.
Which should you choose: the U1542LA or the SRXE4-2X33-EBT-IR1?
Our take: The SRXE4-2X33-EBT-IR1 is the stronger choice when the deployment demands extreme low-light sensitivity, broader IP submersion protection, or government-grade cybersecurity compliance. Key spec deltas: the Pelco achieves 0.003 lux color versus the i-PRO's 0.3 lux — a 100× sensitivity advantage — and its IR reach of approximately 70 m triples the i-PRO's 20 m. The Pelco also extends temperature operation to -50°C versus -30°C and adds IP67/IP68/IPX9K submersion ratings the i-PRO does not carry. The WV-U1542LA is the better fit where standard PoE 802.3af infrastructure is already deployed and cannot support PoE+, where a 7.2 W power budget matters, or where the IK10 shock rating and IP66/NEMA 4X envelope are sufficient — it costs less to switch-provision per port and supports a wider optical zoom range (2.5x–3.3x). NDAA/TAA requirements automatically direct selection to the Pelco.

Frequently Asked Questions
Which should you choose: the U1542LA or the SRXE4-2X33-EBT-IR1?
The SRXE4-2X33-EBT-IR1 is the stronger choice when the deployment demands extreme low-light sensitivity, broader IP submersion protection, or government-grade cybersecurity compliance. Key spec deltas: the Pelco achieves 0.003 lux color versus the i-PRO's 0.3 lux — a 100× sensitivity advantage — and its IR reach of approximately 70 m triples the i-PRO's 20 m. The Pelco also extends temperature operation to -50°C versus -30°C and adds IP67/IP68/IPX9K submersion ratings the i-PRO does not carry. The WV-U1542LA is the better fit where standard PoE 802.3af infrastructure is already deployed and cannot support PoE+, where a 7.2 W power budget matters, or where the IK10 shock rating and IP66/NEMA 4X envelope are sufficient — it costs less to switch-provision per port and supports a wider optical zoom range (2.5x–3.3x). NDAA/TAA requirements automatically direct selection to the Pelco.
Is the i-PRO WV-U1542LA or the Pelco SRXE4-2X33-EBT-IR1 better for low-light performance?
The Pelco SRXE4-2X33-EBT-IR1 is substantially better for low light. Its specified minimum illumination is 0.003 lux color and 0 lux with IR active, versus 0.3 lux color and 0.12 lux B&W for the i-PRO. The Pelco's larger 1/1.8-inch sensor and F1.4 aperture versus the i-PRO's approximately 1/2.7-inch sensor and F2.0–F3.0 aperture explain much of that gap. The Pelco's IR illumination also reaches approximately 70 m compared to the i-PRO's 20 m.
Can I power the Pelco SRXE4-2X33-EBT-IR1 from my existing 802.3af PoE switch?
Based on the provided specs, the Pelco SRXE4-2X33-EBT-IR1 requires PoE+ (802.3at, Class 3), which delivers up to 30 W at the switch port. Standard 802.3af switches are rated to only 15.4 W per port and are not specified as compatible. The i-PRO WV-U1542LA, by contrast, operates on standard PoE 802.3af (Class 0) at 7.2 W, making it directly compatible with existing 802.3af infrastructure.
Which camera is better suited for federal or government projects requiring NDAA and TAA compliance?
The Pelco SRXE4-2X33-EBT-IR1 is the only one of the two that explicitly states NDAA Section 889 and TAA compliance in the provided specifications. It also carries FIPS 140-3 Level 3 certification, TPM, and Secure Boot — requirements commonly mandated on government networks. The i-PRO WV-U1542LA's provided specs do not list NDAA Section 889, TAA compliance, or FIPS 140-3 certifications.
