i-PRO S8543 vs i-PRO S8543L: Specification Comparison
Both the WV-S8543 and WV-S8543L are i-PRO 12MP multi-sensor outdoor fixed IP cameras sharing the same triple 1/2.7-inch CMOS sensor array, 170° panoramic field of view, 2.5x motorized optical zoom, and identical physical footprint. A buyer cross-shopping these two models is typically deciding between the base S8543 and its 'L' (Low-light / IR) variant, which adds built-in IR illumination. This comparison is driven entirely by the provided specifications.

How do the imaging specs compare?
Both cameras share a triple 1/2.7-type CMOS sensor array at 3×4MP (12MP combined), 30 fps, 2688×1520 per-sensor H.265 resolution, and a 2.9–7.3 mm motorized zoom lens delivering 2.5x optical and up to 10.5x extra zoom. Minimum illumination is listed at 0.12 lx (B&W) for both, and maximum dynamic range is 108 dB (Super Dynamic On, Level 31) on both units. The WV-S8543 does not list an IR LED; it states '—' under IR LED Light. The WV-S8543L specifies an IR LED rated at 20 m at 30 IRE and 15 m at 50 IRE, and its minimum illumination measurement carries the qualifier '(B&W, 50IRE, F2.0)'—a more precisely documented condition.
DORI performance is identical across both datasheets: Detect 45.1 m (Wide) / 136.5 m (Tele), Observe 18.0 m / 54.6 m, Recognize 9.0 m / 27.3 m, Identify 4.5 m / 13.6 m. The S8543L provides AI analytics enumerated as eight named types (AI Video Motion Detection, AI Privacy Guard, AI Face Detection, AI People Detection, AI Vehicle Detection, AI Non-Mask Detection, AI Occupancy Detection, AI Scene Change Detection). The S8543 describes its analytics as 'AI video analytics with 8 detection types' but does not individually enumerate them in the provided specs. Both run on the Ambarella CV2 SoC.
What about installation and environment?
Physically, both cameras are identical: dome form factor, ø300 mm × 90 mm (H) body, 3.1 kg (6.83 lbs), aluminum/stainless steel/PC resin construction, IP67/IP66 (IEC 60529), NEMA 4X (UL50E), IK10 impact resistance, and wind resistance up to 40 m/s (~89 mph). Operating temperature is −40 to +60 °C with 10–100% humidity (non-condensing) for both, and both include the same anti-condensation system (Temish element + heater + moisture absorption gel).
Power consumption differs: the WV-S8543 is rated at PoE+ at 17.3 W, while the WV-S8543L is rated at PoE+ (IEEE 802.3at) at 25.4 W—an 8.1 W increase attributable to the IR illuminator. Both require a PoE+ (802.3at / Class 4) switch or injector. Installers should verify that existing PoE+ infrastructure has sufficient per-port power budget for the S8543L, particularly in high-density deployments. Adjusting angle is ±125° pan, ±10°–+105° tilt, ±90° yaw, and ±30° twist on both.
Which fits your VMS and analytics better?
Both cameras support ONVIF Profiles G, M, S, and T and are compatible with iPad, iPhone, and Android terminals. Network interface is 10/100/1000Base-T (RJ-45) on both. Simultaneous user capacity is up to 24 users on both. Supported protocols (IPv4/IPv6 stack including RTSP, MQTT, SNMPv1/v2/v3, 802.1X, LLDP) are materially identical across both specifications. Edge storage uses microSDXC on both.
Security posture shows a minor difference: both list FIPS 140-2 Level 3 and NXP SE050F secure element, but the S8543L additionally notes a GlobalSign certificate, while the S8543 spec references HTTPS and 802.1X in the security field without mentioning GlobalSign. Audio is bidirectional on both (3.5 mm stereo mic input and line output, G.726/G.711 compression); the S8543L explicitly labels its audio transmission mode as 'Interactive (Full duplex)' while the S8543 lists 'Off/Mic input/Audio output/Half duplex/Full duplex' as selectable modes. Alarm I/O: the S8543 specifies 3 alarm inputs, 2 alarm outputs, and 1 aux output; the S8543L states '3× Alarm IN/OUT terminals' without breaking out separate input and output counts in the provided spec field.
Which should you choose: the S8543 or the S8543L?
Our take: The WV-S8543L is the stronger choice when deployments require active IR illumination for low-light or no-light coverage. The defining spec delta is the S8543L's built-in IR LED rated at 20 m (30 IRE) / 15 m (50 IRE), versus no IR LED on the S8543. This directly impacts nighttime image quality without relying on ambient light. The trade-off is power draw: the S8543L consumes 25.4 W (PoE+ 802.3at) compared to the S8543's 17.3 W—an 8.1 W per-port increase that must be budgeted against switch or injector capacity. The S8543L also enumerates eight AI analytics types by name in its specification, providing clearer documentation of the analytics stack. In environments with adequate ambient illumination—parking structures with lighting, city centers, or illuminated perimeters—the S8543's lower power draw makes it the more infrastructure-efficient option. Both models are otherwise mechanically and functionally identical.

Frequently Asked Questions
Which should you choose: the S8543 or the S8543L?
The WV-S8543L is the stronger choice when deployments require active IR illumination for low-light or no-light coverage. The defining spec delta is the S8543L's built-in IR LED rated at 20 m (30 IRE) / 15 m (50 IRE), versus no IR LED on the S8543. This directly impacts nighttime image quality without relying on ambient light. The trade-off is power draw: the S8543L consumes 25.4 W (PoE+ 802.3at) compared to the S8543's 17.3 W—an 8.1 W per-port increase that must be budgeted against switch or injector capacity. The S8543L also enumerates eight AI analytics types by name in its specification, providing clearer documentation of the analytics stack. In environments with adequate ambient illumination—parking structures with lighting, city centers, or illuminated perimeters—the S8543's lower power draw makes it the more infrastructure-efficient option. Both models are otherwise mechanically and functionally identical.
Is the S8543 or S8543L better for low-light or nighttime use?
The WV-S8543L is specified with a built-in IR LED rated at 20 m (30 IRE) / 15 m (50 IRE), making it the documented choice for low-light or complete darkness scenarios. The WV-S8543 lists no IR LED in its specification. Both show the same minimum illumination of 0.12 lx (B&W), but without IR illumination the S8543 depends on available ambient light to reach that threshold.
Will my existing PoE+ switch support both cameras?
Both cameras require PoE+ (IEEE 802.3at), but power draw differs: the WV-S8543 is rated at 17.3 W and the WV-S8543L at 25.4 W. A standard 802.3at port provides up to 30 W, so both are within spec. However, if you are calculating total switch power budget across many ports, the S8543L's additional 8.1 W per camera is a meaningful factor in high-density installations.
Do both cameras support the same AI analytics and VMS integrations?
Both run on the Ambarella CV2 SoC and support ONVIF Profiles G, M, S, and T. Both are described as having 8 AI detection types. The S8543L's specification explicitly enumerates all eight by name (including AI Non-Mask Detection, AI Occupancy Detection, AI Privacy Guard, and others); the S8543 specification states '8 detection types' without individually naming them in the provided data. Buyers requiring confirmed support for a specific detection type should verify against i-PRO's full datasheet before specifying either model.
