The DS-2CD2386G2-IU supports a maximum resolution of 3840 × 2160, which is 8 MP. That gives you the extra image detail buyers usually want when they are trying to capture clearer faces, vehicles, or activity across a wider scene. The datasheet also lists multiple stream resolutions, including 3200 × 1800, 2688 × 1520, 1920 × 1080, and 1280 × 720. So whether the priority is full-detail recording or a lighter live stream, the camera gives you flexible output options.

Yes, the datasheet confirms that the -U version includes a built-in microphone. It specifically lists “Built-in microphone for real-time audio security (-U)” and also shows “Built-in Microphone -U: Yes” in the interface section. Audio details are also provided, including mono sound, supported codecs, and sampling rates. That matters for buyers who want more context around an event instead of relying on video alone.

Yes, this model supports PoE. The datasheet lists PoE: 802.3af, Class 3, along with a power range of 36 V to 57 V and maximum PoE consumption of 6.8 W. It also supports 12 VDC ± 25% through a coaxial power plug if that is preferred for the installation. For many buyers, PoE is useful because it can simplify cabling by allowing power and data through the network connection.

Yes, the datasheet states that the camera is rated IP67 for water and dust resistance. It also lists an operating temperature range of -30 °C to 60 °C (-22 °F to 140 °F) with humidity up to 95% non-condensing. Those specifications make it a strong fit for outdoor environments where weather exposure is a real concern. The housing is also listed as metal, which adds to the camera’s durability.

The datasheet highlights Powered-by-DarkFighter technology for low-light performance. It lists minimum illumination as 0.003 Lux in color at F1.6 with AGC on, and 0 Lux with IR in black and white mode. The camera also includes an IR illuminator with smart supplement light, 850 nm wavelength, and an IR range of up to 30 meters. In practical terms, that gives buyers a camera designed to keep producing usable video when lighting conditions drop.

Yes, this is one of the key reasons buyers look at this model. The datasheet says AcuSense technology focuses on human and vehicle target classification, and it lists perimeter protection features including line crossing detection, intrusion detection, region entrance detection, and region exiting detection. It also notes that motion detection includes human and vehicle target classification. That helps reduce less useful alerts and keeps attention on the activity most buyers actually care about.

Yes, the camera has built-in on-board storage support. The datasheet lists a micro SD/SDHC/SDXC slot with capacity up to 512 GB. It also mentions NAS support and auto network replenishment (ANR), which gives additional recording flexibility. For buyers who want edge recording at the camera, this is an important feature because it can add redundancy or reduce dependence on constant network recording.

The datasheet lists fixed focal lens options in 2.8 mm, 4 mm, and 6 mm. It also provides the field of view for each option, with the 2.8 mm lens offering the widest angle and the 6 mm lens offering a narrower, more focused view. That gives buyers a way to choose based on coverage needs rather than trying to force one lens into every scenario. The available model section confirms that the DS-2CD2386G2-IU comes in 2.8/4/6 mm variants.

Yes, the camera supports 120 dB true WDR. The datasheet specifically mentions clear imaging against strong back light using 120 dB true WDR technology. This matters in areas like entryways, storefronts, garages, or loading doors where bright daylight and darker shaded areas appear in the same scene. It helps the camera retain more useful detail instead of forcing buyers to choose between blown-out highlights and dark shadows.

The datasheet lists several optional accessories for mounting and installation. These include the DS-1276ZJ-SUS corner mount, DS-1275ZJ-SUS vertical pole mount, DS-1271ZJ-140 pendant mount, DS-1273ZJ-140B wall mount, DS-1273ZJ-140 wall mount, and DS-1280ZJ-PT6 junction box. That gives buyers flexibility to adapt the same camera to different installation surfaces and layouts. It is helpful when the mounting environment is already decided and the camera needs to fit the site instead of the other way around.
