ACTi A422 vs i-PRO U1542LA: Specification Comparison
This comparison covers two 4MP outdoor motorized-varifocal bullet cameras aimed at commercial surveillance installations: the ACTi A422 and the i-PRO WV-U1542LA. Both share a 2688×1520 resolution, 1/2.7-inch CMOS sensors, H.265/H.264/MJPEG compression, IK10 impact resistance, and RJ-45 network connections. Key differentiators span IR range, dynamic range, zoom ratio, power class, audio capability, edge storage, and operating temperature envelope—factors that matter significantly depending on the installation environment and VMS ecosystem.

How do the imaging specs compare?
Both cameras produce 4MP (2688×1520) at 30 fps from a 1/2.7-inch CMOS sensor. The A422 delivers a 5x optical zoom over a 2.7–13.5 mm focal range, while the WV-U1542LA offers a 2.5x optical zoom across 2.9–7.3 mm (extendable to 3.3x at 1920×1080). For scenes requiring tighter reach, the A422's broader zoom ratio provides more flexibility without repositioning the camera.
Low-light performance diverges substantially. The A422 achieves a minimum illumination of 0.003 lux in color and 0 lux with IR active, backed by an 850 nm IR illuminator rated to 85 m. The WV-U1542LA requires 0.3 lux in color and 0.12 lux in B&W, with IR limited to 20 m. Dynamic range also differs: the A422 specifies Extreme WDR at 150 dB, whereas the WV-U1542LA lists a maximum of 102 dB (Super Dynamic, level 31). These gaps are meaningful in high-contrast or very low-light outdoor scenes.
What about installation and environment?
The A422 carries an IP68 ingress rating, offering continuous submersion resistance beyond the IP66/IP67 threshold. The WV-U1542LA is rated IP66, Type 4X (UL50E), and NEMA 4X, providing strong water and dust protection with certified wind resistance up to 40 m/s (approximately 89 mph)—a rating the A422 spec sheet does not include. Both achieve IK10 impact resistance. Operating temperature for the A422 spans -40°C to 60°C, versus -30°C to 50°C for the WV-U1542LA, giving the A422 a wider thermal envelope for extreme-cold or high-heat deployments.
Power requirements differ in class: the A422 spec sheet references both PoE Class 3 (802.3af) and PoE++ (802.3bt), which should be confirmed with ACTi before switch selection. The WV-U1542LA operates on standard PoE 802.3af (Class 0, 7.2 W), compatible with the widest range of existing PoE infrastructure. The A422 is heavier at 1,410 g versus the WV-U1542LA's 860 g, and supports pole and corner mount types; the WV-U1542LA's mount options are not detailed in the provided specs.
Which fits your VMS and analytics better?
For VMS integration, the A422 supports ONVIF Profile S, G, T, and M. The WV-U1542LA supports Profile G, S, and T; Profile M compliance is not stated in the provided specs. Both cameras support two-way VMS recording via Profile G. The A422 includes two-way audio (line-in, line-out); the WV-U1542LA's audio input and output fields are listed as not specified, so audio capability should not be assumed without vendor confirmation.
On-camera analytics differ in depth: the A422 incorporates a dedicated Deep Learning Processing Unit (DLPU) supporting deep learning-based analytics alongside Video Motion Detection. The WV-U1542LA provides VMD (4 areas) and Scene Change Detection—rules-based, without a stated deep learning engine. Edge storage is available only on the WV-U1542LA, which accepts microSDXC up to 512 GB, enabling local recording or buffering independent of NVR connectivity; the A422 does not specify edge storage in the provided specs. Warranty periods are 3 years for the A422 and 5 years for the WV-U1542LA.
Which should you choose: the A422 or the U1542LA?
Our take: The A422 is the stronger choice when long-range IR coverage, high dynamic range, and deep-learning analytics are the primary requirements; the WV-U1542LA is preferable when edge storage, a longer warranty, and simpler PoE infrastructure are the priority. On imaging reach, the A422's 85 m IR versus the WV-U1542LA's 20 m IR is a decisive advantage for large parking areas or perimeter applications. Dynamic range is 150 dB (A422) versus 102 dB (WV-U1542LA), a meaningful gap in high-contrast scenes such as loading dock entrances with mixed daylight and shadow. Temperature tolerance extends to -40°C on the A422 versus -30°C on the WV-U1542LA, relevant for unheated northern installations. Conversely, the WV-U1542LA's 512 GB microSDXC edge storage and 5-year warranty reduce long-term infrastructure and support cost, and its 802.3af-only power draw ensures compatibility with legacy PoE switches without verifying 802.3bt support.

Frequently Asked Questions
Which should you choose: the A422 or the U1542LA?
The A422 is the stronger choice when long-range IR coverage, high dynamic range, and deep-learning analytics are the primary requirements; the WV-U1542LA is preferable when edge storage, a longer warranty, and simpler PoE infrastructure are the priority. On imaging reach, the A422's 85 m IR versus the WV-U1542LA's 20 m IR is a decisive advantage for large parking areas or perimeter applications. Dynamic range is 150 dB (A422) versus 102 dB (WV-U1542LA), a meaningful gap in high-contrast scenes such as loading dock entrances with mixed daylight and shadow. Temperature tolerance extends to -40°C on the A422 versus -30°C on the WV-U1542LA, relevant for unheated northern installations. Conversely, the WV-U1542LA's 512 GB microSDXC edge storage and 5-year warranty reduce long-term infrastructure and support cost, and its 802.3af-only power draw ensures compatibility with legacy PoE switches without verifying 802.3bt support.
Does either camera support local SD card recording?
Only the i-PRO WV-U1542LA supports onboard edge storage, accepting microSDXC cards up to 512 GB and microSDHC up to 32 GB. The ACTi A422 does not specify edge storage in the provided specifications, so local recording capability cannot be assumed for that model without confirming with ACTi directly.
Can I use these cameras with my existing PoE switches?
The i-PRO WV-U1542LA is rated at 7.2 W and operates on standard IEEE 802.3af PoE (Class 0), which is compatible with virtually all managed and unmanaged PoE switches. The ACTi A422 spec sheet references both PoE Class 3 (802.3af) and PoE++ (802.3bt); you should confirm the actual power draw with ACTi before assuming 802.3af compatibility to avoid underpower situations.
Which camera handles very dark or nighttime outdoor conditions better?
The ACTi A422 has a significantly lower minimum illumination—0.003 lux in color and 0 lux with IR active—and an IR range of 85 m at 850 nm. The i-PRO WV-U1542LA requires 0.3 lux in color (0.12 lux in B&W) and its IR illuminator reaches only 20 m. For large unlit outdoor areas, the A422 provides materially better low-light reach based on the specifications provided.
