Hikvision DS-2CD2043G2-I 4MP AcuSense Bullet Camera with Human Vehicle Detection

Yes. The DS-2CD2043G2-I is a 4MP AcuSense fixed bullet network camera, and the datasheet lists a maximum resolution of 2688 × 1520. It also supports up to 25 fps at 2688 × 1520 in 50 Hz mode and up to 30 fps at 2688 × 1520 in 60 Hz mode. That matters because it gives buyers a good balance between image detail and smooth playback for everyday security use. It is a strong fit when you want clearer footage than basic 1080p without jumping into a much heavier bandwidth class.

The datasheet lists three fixed lens options: 2.8 mm, 4 mm, and 6 mm. Each option changes the field of view, with 2.8 mm giving the widest horizontal view at 103°, 4 mm giving 84°, and 6 mm narrowing down to 52°. That matters because buyers usually want to choose between broader area coverage and a tighter, more focused image. In practical use, 2.8 mm is often better for wide scenes, while 6 mm is more useful when you need more distance detail on a narrower target area.

Yes. The datasheet shows minimum illumination of 0.005 Lux in color at F1.6 with AGC on, and 0 Lux with IR on. It also lists an IR range of up to 40 meters, which helps the camera continue monitoring when visible light drops. That matters because many buyers are really asking whether the camera will still produce usable footage after dark, not just whether it technically has night vision. For driveways, entry points, and building perimeters, that extra IR range can make a real difference.

Yes. This model is part of Hikvision’s AcuSense family, and the datasheet says it focuses on human and vehicle targets classification based on deep learning. It also lists motion detection with human and vehicle targets classification, plus perimeter protection features like line crossing detection and intrusion detection with human and vehicle classification support. That matters because it helps reduce less useful alerts from general movement. For buyers, that usually means fewer nuisance notifications and a better chance of catching activity that actually matters.

Yes. The main stream supports H.265, H.264, H.264+, and H.265+, while the sub-stream supports H.265, H.264, and MJPEG. The datasheet also lists a video bit rate range of 32 Kbps to 8 Mbps. That matters because better compression can help reduce storage usage and bandwidth demand, especially when multiple cameras are recording at the same time. For buyers building out a larger system, that can make the camera much easier to manage long term.

The standard DS-2CD2043G2-I does not list a built-in microphone in the available model name, but the datasheet does show that the -U version does. Specifically, it states “-U: Built-in microphone: Yes,” along with audio compression, sampling rate, and noise filtering details for the -U model. That matters because buyers sometimes compare the -I and -IU versions and assume they are the same. If audio is important for the installation, the datasheet points to the DS-2CD2043G2-IU rather than the standard -I model.

Yes. The interface section lists built-in microSD storage support up to 512 GB. The datasheet also mentions NAS storage and auto network replenishment, which gives buyers more than one way to handle recording. That matters because some users want direct edge recording on the camera, while others want backup recording if the network path is interrupted. It adds flexibility and can help reduce the risk of missing footage.

Yes. The datasheet lists IP67 protection, which means the camera is water and dust resistant for outdoor environments. It also shows startup and operating conditions from -30 °C to 60 °C with humidity up to 95% non-condensing. That matters because outdoor buyers want to know whether the camera can handle rain, dust, and temperature swings without being treated like an indoor-only unit. The one limitation the datasheet mentions is that this model has no specific anti-corrosion protection for harsher specialized environments.

It supports both. The datasheet lists 12 VDC ±25% with reverse polarity protection, and it also supports PoE under IEEE 802.3af Class 3. Maximum power consumption is listed as 6 W on 12 VDC and 7 W on PoE. That matters because PoE can simplify installation by carrying power and data over one cable, while 12 VDC gives another option when PoE is not available. For most buyers, that flexibility makes the camera easier to fit into existing systems.

The datasheet lists one optional accessory: the DS-1280ZJ-XS junction box. That matters because buyers often want to know whether there is a clean mounting solution for cable management and installation. A junction box can help make the final install look more professional and better protected. It is especially useful when the camera is being mounted in exposed outdoor locations where cable termination needs extra protection.
