The DS-2CD2087G2-LU delivers a maximum resolution of 3840 × 2160, which is 8 megapixels. According to the datasheet, this 4K resolution provides highly detailed images that are suitable for identifying people, vehicles, and fine scene details. The camera uses a 1/1.2" progressive scan CMOS sensor to achieve this level of image quality. This makes it ideal for applications where clarity and evidence-level detail are required. 

Yes, this camera is designed for 24/7 full-color imaging using Hikvision ColorVu technology. The datasheet states that it features an F1.0 super-aperture lens and a high-performance sensor to collect more light. It can capture color images down to 0.0005 lux, and even at 0 lux when the built-in white light is enabled. This allows consistent color detail day and night instead of switching to black-and-white. 

The DS-2CD2087G2-LU supports smart event detection based on deep learning technology. According to the datasheet, it can classify human and vehicle targets for motion detection. It also supports perimeter protection features such as line crossing, intrusion, region entrance, and region exiting. These capabilities help reduce false alarms caused by irrelevant motion. 

The DS-2CD2087G2-LU model does not include a built-in microphone. The datasheet notes that built-in audio is available only on the -U variant of this camera series. However, the -LU version focuses on high-quality video and smart detection features. Users requiring audio recording would need to select the appropriate variant. 

This camera is available with fixed focal lens options of 2.8 mm, 4 mm, or 6 mm. According to the datasheet, the 2.8 mm lens provides a 102° horizontal field of view, the 4 mm lens provides 88°, and the 6 mm lens provides 54°. All lenses use an F1.0 aperture to maximize light intake. These options allow flexibility depending on coverage and distance requirements.

Yes, the camera is designed for outdoor environments. The datasheet lists an IP67 rating, which indicates protection against dust and water ingress. It also supports operating temperatures from -30 °C to 60 °C (-22 °F to 140 °F). These specifications make it suitable for most standard outdoor installations.

Yes, the DS-2CD2087G2-LU includes a built-in memory card slot. According to the datasheet, it supports microSD, microSDHC, microSDXC, or TF cards with capacities of up to 512 GB. This allows video to be recorded directly on the camera without requiring an NVR. Local storage can also serve as backup recording if the network connection is lost. 

The camera supports several efficient video compression standards. The datasheet lists H.265, H.264, H.264+, and H.265+ for the main stream, with H.265, H.264, and MJPEG for sub-streams. These formats help reduce bandwidth and storage requirements while maintaining image quality. This is especially beneficial for long-term or high-resolution recording. 

The camera supports both 12 VDC power input and Power over Ethernet (PoE). According to the datasheet, it is compatible with IEEE 802.3af PoE, Class 3, with a maximum power consumption of 7.5 W. It also supports 12 VDC ±25% with reverse polarity protection. This dual-power support provides flexibility during installation.
