i-PRO S4576LA vs i-PRO S4576LMA: Specification Comparison
The i-PRO WV-S4576LA and WV-S4576LMA are both 12MP AI-enabled outdoor fisheye dome IP cameras from i-PRO, sharing the same 1/2-type CMOS sensor, 1.4 mm fixed fisheye lens, 183° horizontal and vertical field of view, and 14 m IR illumination. They target the same perimeter and wide-area surveillance use cases and are powered identically via PoE 802.3af. This comparison examines where the two models diverge across imaging performance, installation and environmental tolerance, and VMS integration and analytics capability.

How do the imaging specs compare?
Both cameras share the same 1/2-type 12MP CMOS sensor, 1.4 mm focal length, f/1.9 maximum aperture, and 183°×183° angular field of view. Minimum illumination is identical at 0.3 lx (color) and 0.04 lx (B&W). Dynamic range is specified at a maximum of 84 dB on both units with WDR/Super Dynamic at level 31. The S4576LMA explicitly lists its ceiling-mode output resolution as 2992×2992 (fisheye) and 2560×1920 (PTZ dewarped view); the S4576LA spec does not list discrete resolution figures in the provided data. IR illumination range is rated at 14 m on both models.
The most concrete imaging difference is frame rate: the S4576LMA is specified at 30 fps, while the S4576LA is specified at 25 fps. Image compensation wording also differs slightly—the S4576LA lists 'Adaptive black stretch, BLC, fog, HLC, DNR,' while the S4576LMA lists 'Adaptive BLC, Fog, HLC, DNR,' omitting explicit mention of adaptive black stretch. Both use the same Ambarella CV22 SoC. Operating temperature affects IR performance on the S4576LA: its spec states -40°C to +50°C with IR on and -40°C to +60°C with IR off; the S4576LMA lists a single -40°C to +60°C range with no IR-state distinction.
What about installation and environment?
Both cameras carry IP66 (IEC 60529), NEMA 4X (UL50), IK10 (IEC 62262), and 50 J shock resistance (IEC 60068-2-75), and both include a Rosahl anti-condensation element and wind resistance rated to 40 m/s (~89 mph). Power input is identical: DC 12V 1.1A or PoE IEEE 802.3af (Class 0). The S4576LMA provides explicit physical dimensions (ø154 mm × 60.3 mm H, dome radius 35 mm) and a stated mass of 880 g; the S4576LA lists mass as 880 g (plate) or 1.3 kg (bracket) but does not provide body dimensions in the provided spec data.
Railway compliance differs: the S4576LMA is listed as EN45545 compliant in addition to EN50155-TX; the S4576LA lists EN50155-TX only, with no EN45545 mention in the provided specs. Finish materials also differ—the S4576LA is described as aluminum die cast with a polycarbonate dome, while the S4576LMA is listed as aluminum, stainless steel, and polycarbonate. Mount types listed for the S4576LA include wall, ceiling, and rack; the S4576LMA lists wall and ceiling only (rack not stated in the provided specs). Both offer a fixing angle adjustment of -5°, 0°, or +5°.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, M, S, and T; H.265/H.264 with CBR/VBR; JPEG at 10 image quality steps; and mobile compatibility with iOS and Android. Both carry identical AI analytics packages: AI-VMD, AI People Counting for 360° fisheye, AI Privacy Guard for 360° fisheye, AI Scene Change Detection, and AI Sound Classification (Gunshot, Yell, Vehicle Horn, Glass Break). VMD supports 4 areas and SCD supports 1 area on both models. Privacy zone masking allows up to 8 zones on both. Both include 3× Alarm IN, 1× Alarm OUT, and 1× AUX OUT terminals. The S4576LA specifies smart coding options including GOP control and Auto VIQS; these are not listed in the provided S4576LMA spec data.
Audio I/O is present on both: mic/line input and audio output via 3.5 mm jack. The S4576LA specifies audio compression codecs explicitly (G.726 ADPCM at 16/32 kbps, G.711 at 64 kbps). The S4576LMA spec does not list codec options in the provided data. The S4576LA specifies a maximum of 14 concurrent users; no concurrent user limit is stated in the provided S4576LMA spec data. Both support microSD edge storage. The S4576LA lists alarm actions as email, HTTP, TCP notification, and SD recording; the S4576LMA lists email, HTTP, and TCP notification—SD recording as an alarm action is not stated in the provided S4576LMA spec data. Both support signed firmware and HTTPS encryption. GUI languages are listed as 9 named languages on the S4576LA and '9 languages' (unnamed) on the S4576LMA.
Which should you choose: the S4576LA or the S4576LMA?
Our take: The S4576LMA is the stronger choice when maximum frame rate and the broadest rail-compliance certification matter most, while the S4576LA better suits deployments that need explicit smart-coding controls and SD-triggered alarm recording. The S4576LMA is specified at 30 fps versus the S4576LA's 25 fps—a meaningful delta for motion-blur-sensitive analytics. The S4576LMA adds EN45545 railway fire-safety compliance not listed for the S4576LA. Conversely, the S4576LA spec explicitly documents GOP/Auto VIQS smart coding and SD card alarm-action recording, neither of which appears in the provided S4576LMA data. Operating temperature with IR active is specified at -40°C to +50°C for the S4576LA versus -40°C to +60°C (no IR-state caveat) for the S4576LMA, giving the LMA a stated 10°C advantage in hot IR-on deployments. Both deliver identical 12MP fisheye imaging, 14 m IR, 84 dB WDR, IP66/IK10 protection, and the full AI analytics suite.

Frequently Asked Questions
Which should you choose: the S4576LA or the S4576LMA?
The S4576LMA is the stronger choice when maximum frame rate and the broadest rail-compliance certification matter most, while the S4576LA better suits deployments that need explicit smart-coding controls and SD-triggered alarm recording. The S4576LMA is specified at 30 fps versus the S4576LA's 25 fps—a meaningful delta for motion-blur-sensitive analytics. The S4576LMA adds EN45545 railway fire-safety compliance not listed for the S4576LA. Conversely, the S4576LA spec explicitly documents GOP/Auto VIQS smart coding and SD card alarm-action recording, neither of which appears in the provided S4576LMA data. Operating temperature with IR active is specified at -40°C to +50°C for the S4576LA versus -40°C to +60°C (no IR-state caveat) for the S4576LMA, giving the LMA a stated 10°C advantage in hot IR-on deployments. Both deliver identical 12MP fisheye imaging, 14 m IR, 84 dB WDR, IP66/IK10 protection, and the full AI analytics suite.
Is the S4576LA or S4576LMA better for smooth motion capture?
Based on the provided specifications, the S4576LMA is rated at 30 fps versus 25 fps for the S4576LA. For motion-sensitive analytics or forensic review of fast-moving subjects, the S4576LMA's higher frame rate is the specified advantage.
Do both cameras work in extreme heat with IR illumination on?
Not identically per the provided specs. The S4576LA is specified at a maximum of +50°C ambient with IR on and +60°C with IR off. The S4576LMA lists a single operating range of -40°C to +60°C with no IR-state distinction. In sustained hot environments where IR must remain active, the S4576LMA's spec does not carry the +50°C IR-on ceiling stated for the S4576LA.
Are the AI analytics the same on both cameras?
Yes, based on the provided specifications. Both the S4576LA and S4576LMA include identical AI analytics: AI-VMD, AI People Counting for 360° fisheye, AI Privacy Guard for 360° fisheye, AI Scene Change Detection, and AI Sound Classification covering gunshot, yell, vehicle horn, and glass break. Both also support 4-area VMD, 8-zone privacy masking, and ONVIF Profiles G, M, S, and T.
