Selection notes

• The cited datasheet covers a family of dome cameras. Confirm the complete model, lens, colour, hardware and firmware before selection.
• These details apply to DS-2CD2183G2-LIS2U non-T, non-SKD member only. Confirm the supplied configuration; the -S interface and -2U audio specifications apply to the corresponding suffixes.
• Lens-specific FOV, depth and DORI values apply only to the selected lens. DORI and lighting ranges are references, not field identification guarantees.
• Third stream is available under certain settings only. Card encryption and health detection require a high-end compatible Hikvision card.
• External line audio does not establish an included or built-in speaker. Check external audio/alarm loads, power and the actual recorder configuration.
• Match the full ordering code when requesting a quote. Lens, colour, T, SKD and regional versions must be confirmed separately.
• Use the power figures shown for this LIS2U model. The lower -LI(T) values belong to a different version.
• Enclosure ratings do not establish coastal or chemical-corrosion suitability. Mounting parts, cards and package contents require confirmation.
• ISD supplies products only. Confirm stock, price, lead time, local warranty and the actual supplied configuration separately.
