According to the datasheet, the DS-2CD2343G2-I(U) delivers a maximum resolution of 2688 × 1520, which equals 4 megapixels. This resolution provides clear and detailed images suitable for identifying people, vehicles, and activity in monitored areas. Higher resolution also allows for better digital zoom without losing critical detail. This makes the camera effective for both real-time monitoring and recorded evidence review.

Yes, the datasheet confirms that this model uses Hikvision AcuSense technology powered by deep learning algorithms. It supports human and vehicle targets classification for motion detection and perimeter protection. This allows the camera to focus on meaningful events rather than irrelevant motion like rain or shadows. As a result, alarm accuracy and efficiency are significantly improved.

The “-U” version of the DS-2CD2343G2-I(U) includes a built-in microphone, as stated in the datasheet. This enables real-time audio monitoring in addition to video recording. Multiple audio compression formats and sampling rates are supported. Audio can provide additional context for security events when enabled and legally permitted.

The datasheet lists a minimum illumination of 0.005 lux in color mode and 0 lux with infrared enabled. The built-in IR illuminator provides night vision with a range of up to 30 meters. An ICR cut filter automatically switches between day and night modes. This ensures reliable imaging around the clock, even in complete darkness.

Yes, the camera supports 120 dB Wide Dynamic Range (WDR), according to the datasheet. WDR helps balance bright and dark areas within the same scene. This is especially useful in entrances, loading bays, or areas with direct sunlight. It ensures subjects remain visible instead of appearing silhouetted.

The datasheet lists two fixed lens options: 2.8 mm and 4 mm. The 2.8 mm lens provides a wider field of view, while the 4 mm lens offers more focused coverage. Horizontal fields of view range from 103° (2.8 mm) to 84° (4 mm). This allows installers to choose the lens that best fits the surveillance area.

Yes, the camera includes a built-in microSD card slot as specified in the datasheet. It supports microSD cards with capacities of up to 512 GB. This allows for local video storage directly on the camera. Onboard storage can be useful for redundancy or standalone recording scenarios.

The datasheet indicates support for H.265, H.264, H.265+, and H.264+ video compression. These formats help reduce bandwidth and storage requirements while maintaining image quality. H.265+ and H.264+ are especially useful for long-term recording. This makes the camera more efficient for network and storage planning.

Yes, the camera is rated IP67 for water and dust resistance, as stated in the datasheet. This rating makes it suitable for outdoor environments exposed to rain and dust. The aluminum alloy housing adds durability for long-term use. However, the datasheet notes that it has no specific anti-corrosion protection.

The camera can be powered either by 12 VDC or via Power over Ethernet (PoE). It supports IEEE 802.3af PoE, Class 3, according to the datasheet. Maximum power consumption is listed as up to 7 W when using PoE. This flexibility simplifies installation and reduces the need for additional power outlets.
