ACTi A423 vs i-PRO S15600-V2LN: Specification Comparison
Both the ACTi A423 and i-PRO WV-S15600-V2LN are 6MP outdoor fixed bullet cameras with motorized varifocal lenses, IR illumination, and H.265/H.264/MJPEG compression — a pairing a buyer would legitimately cross-shop for perimeter or entrance surveillance. The comparison below covers imaging performance, physical installation requirements, and VMS/analytics integration, drawing exclusively from the manufacturer specifications provided for each model.

How do the imaging specs compare?
The ACTi A423 uses a 1/2.4" sensor resolving 3864×2192 and delivers a 5× motorized optical zoom spanning 2.7–13.5 mm, giving it notably wider focal reach than the i-PRO WV-S15600-V2LN, whose 1/1.8" sensor outputs a maximum resolution of 3328×1872 and uses a 2×motorized zoom (4.3–8.6 mm, 53°–104° FOV). The larger physical sensor on the i-PRO captures more light per pixel; its minimum illumination is listed at 0.03 lux (B&W, 50 IRE, F1.5, 1/30s), while the A423 achieves 0.003 lux in color and 0 lux with IR active — a ten-fold advantage in stated color sensitivity.
For WDR, the A423 claims 150 dB Extreme WDR against the i-PRO's maximum of 132 dB Super Dynamic (at Level 30+, 15 fps). IR range also favors the A423 at 85 m (850 nm), versus 70 m (30 IRE) / 50 m (50 IRE) for the i-PRO. Both cameras run at 30 fps maximum. The i-PRO additionally documents DORI detection distances (Wide detect: 52 m, Tele detect: 133.5 m), which the A423 spec sheet does not provide, making direct lensed-range comparison at DORI criteria impossible.
What about installation and environment?
The A423 carries an IP68 ingress rating — full dust-tight and continuous submersion protection — and IK10 vandal resistance, operating from −40°C to +60°C. The i-PRO WV-S15600-V2LN is rated IP66 and NEMA 4X (powerful water jets, not submersion) plus IK10, with the same −40°C to +60°C operating range (though its spec notes power-on activation requires −30°C or above). The i-PRO also specifies wind resistance up to 40 m/s (~89 mph) and an active anti-condensation system (Temish element + heater + moisture absorption gel); the A423 spec does not document equivalent wind or condensation specifications.
Power differs meaningfully: the A423 lists PoE++ (802.3bt) Class 3 and DC 12V as its power sources and states a 95 W maximum PoE wattage — buyers should verify this against their switch budgets. The i-PRO is powered by 802.3af PoE (Class 0) or DC 12V at 1.0 A, a far lower budget compatible with standard PoE switches without 802.3bt support. Physically, the A423 measures 297.1×96.2×91.5 mm; the i-PRO is ø133×133×383 mm (approx. 2.4 kg). The A423 supports pole and corner mounts per spec; the i-PRO supports ceiling, wall, and specific pan/tilt/yaw adjustment ranges.
Which fits your VMS and analytics better?
Both cameras are ONVIF-compliant across Profiles S, G, T, and M, so either will integrate with standard VMS platforms. The i-PRO WV-S15600-V2LN adds an Ambarella CV22 SoC with documented AI analytics including AI Video Motion Detection, AI Sound Classification (gunshot, yell, vehicle horn, glass break), Scene Change Detection, up to 14 simultaneous ONVIF streams, and FIPS 140-2 Level 3 / NXP SE050F hardware security — a notably deeper analytics and cybersecurity stack than the A423 spec documents. The A423 lists Deep Learning (DLPU) and VMD analytics but does not specify an SoC or enumerate specific AI object classes.
Audio support is two-way on both cameras; the i-PRO exposes 3.5 mm stereo jacks for mic input and audio output with G.726, G.711, and AAC-LC compression, while the A423 lists line-in/line-out. The i-PRO specifies 3 alarm inputs, 1 alarm output, and 1 AUX output on external I/O terminals; the A423 spec does not enumerate discrete alarm terminal counts. On-board storage: the i-PRO supports SDXC/SDHC/SD with multiple recording modes (manual, alarm, schedule, network-failure backup); the A423 spec as provided does not document an SD card slot. Security certifications differ: the i-PRO holds UL 62368-1, c-UL, CE, FCC Part 15, and FIPS 140-2 Level 3; the A423 lists UL Taiwan IoT Cybersecurity Certification only.
Which should you choose: the A423 or the S15600-V2LN?
Our take: The A423 is the stronger choice when the installation demands maximum zoom range, deeper IP ingress protection, or extreme low-light color sensitivity. Its 5× optical zoom (2.7–13.5 mm) versus the i-PRO's 2× (4.3–8.6 mm) provides significantly more standoff distance flexibility; its IP68 rating exceeds the i-PRO's IP66 for wash-down or flood-prone environments; and its stated minimum illumination of 0.003 lux in color versus the i-PRO's 0.03 lux gives a ten-fold edge in ambient low-light performance. However, the i-PRO WV-S15600-V2LN is the better fit for installations on standard 802.3af PoE infrastructure — it draws power within 802.3af Class 0 limits, whereas the A423 requires 802.3bt PoE++ capable switches. The i-PRO also offers a documented AI sound classification engine, FIPS 140-2 Level 3 hardware security, SD card on-board recording, and a 5-year warranty versus the A423's 3-year warranty — advantages for enterprise and government deployments prioritizing edge analytics, cybersecurity compliance, and longer service coverage.

Frequently Asked Questions
Which should you choose: the A423 or the S15600-V2LN?
The A423 is the stronger choice when the installation demands maximum zoom range, deeper IP ingress protection, or extreme low-light color sensitivity. Its 5× optical zoom (2.7–13.5 mm) versus the i-PRO's 2× (4.3–8.6 mm) provides significantly more standoff distance flexibility; its IP68 rating exceeds the i-PRO's IP66 for wash-down or flood-prone environments; and its stated minimum illumination of 0.003 lux in color versus the i-PRO's 0.03 lux gives a ten-fold edge in ambient low-light performance. However, the i-PRO WV-S15600-V2LN is the better fit for installations on standard 802.3af PoE infrastructure — it draws power within 802.3af Class 0 limits, whereas the A423 requires 802.3bt PoE++ capable switches. The i-PRO also offers a documented AI sound classification engine, FIPS 140-2 Level 3 hardware security, SD card on-board recording, and a 5-year warranty versus the A423's 3-year warranty — advantages for enterprise and government deployments prioritizing edge analytics, cybersecurity compliance, and longer service coverage.
Is the A423 or S15600-V2LN better for low-light color imaging?
Based on the provided specifications, the ACTi A423 has a lower stated minimum illumination — 0.003 lux in color versus the i-PRO WV-S15600-V2LN's 0.03 lux (B&W, 50 IRE). The A423 also specifies 0 lux operation with IR active and an 85 m IR range versus the i-PRO's 70 m (30 IRE). On paper, the A423 has a meaningful low-light advantage, though the i-PRO's larger 1/1.8" sensor versus the A423's 1/2.4" sensor may affect real-world performance in ways not captured by lux ratings alone.
Can I power either camera from a standard 802.3af PoE switch?
The i-PRO WV-S15600-V2LN is specified as PoE 802.3af (Class 0) compatible, so it will power from any standard 802.3af switch. The ACTi A423 lists PoE++ (802.3bt) Class 3 and a 95 W maximum PoE wattage, which requires an 802.3bt-capable switch or injector — a standard 802.3af switch may not supply sufficient power. Confirm with your switch's per-port PoE budget before deploying the A423.
Which camera has stronger AI analytics and cybersecurity features?
The i-PRO WV-S15600-V2LN documents a more extensive AI and security stack: its Ambarella CV22 SoC supports AI Video Motion Detection and AI Sound Classification (gunshot, yell, vehicle horn, glass break), and it carries FIPS 140-2 Level 3 and NXP SE050F hardware security certifications. The ACTi A423 lists Deep Learning (DLPU) and VMD but does not specify an SoC, enumerate AI object classes, or list FIPS certification. For deployments requiring documented edge AI sound detection or government-grade hardware security, the i-PRO spec is more complete as provided.
