4 MP ColorVu bullet camera with sound and night lighting
This camera combines high image quality, color recording in low light, and analysis of people and vehicles. The compact bullet housing makes it suitable for facades, driveways, courtyards, and other areas where the camera direction needs to be clearly visible.
4 MP delivers clear images
The camera records in up to 2688 × 1520 pixels at up to 25 frames per second at 50 Hz. That gives you clear recordings where people, vehicles, and events are easier to see.
The higher resolution also makes it easier to zoom in on parts of the image when reviewing footage later.
Color images in very low light
ColorVu technology helps the camera keep colors even when there is very little light in the area. Colors can make it easier to distinguish, for example, clothing, vehicles, and other details.
When there isn’t enough normal light, the camera can use its built-in white light to continue delivering color recordings.
IR and white light up to 40 meters
The camera has both infrared light and white light with a range of up to 40 meters.
IR provides discreet black-and-white night recordings, while the white light can be used for color recordings. You can choose the lighting that best suits the area and the surveillance you want.
Three lighting modes
The camera supports several ways of using IR and white light. Among other things, it can record with IR, use white light, or switch between the light types depending on the chosen setup.
That gives you the option of discreet monitoring for everyday use and color recordings when you need more detail.
People and vehicle detection
The camera can distinguish between people and vehicles. This reduces the number of unnecessary alerts from things like animals, rain, leaves, and other movement in the image.
That gives you a clearer alarm history with more focus on relevant events.
Line crossing and area detection
The camera supports line crossing, intrusion, and movement into or out of defined areas.
For example, you can receive an alarm if a person or vehicle crosses a specific boundary or moves into an area that needs to be monitored.
Built-in dual microphone
The DS-2CD2047G3-LI2UY version has two built-in microphones that can record sound together with the video.
Audio can provide extra information about an event and make it easier to understand what happened at the scene.
Noise filtering
The camera can filter out some of the constant background noise from audio recordings. This can provide more usable sound in areas with ventilation, traffic, or other ongoing noise.
Lens for a wide or more focused overview
The camera is available with a 2.8 mm or 4 mm fixed lens. The 2.8 mm version gives the widest viewing angle and works well for areas close to the camera.
The 4 mm version gives a narrower image and shows the subject a little larger at longer distances.
Clear images in backlight
The camera can preserve more detail when there are both very bright and dark areas in the same image.
This is useful, for example, at entrances, gates, and facades, where sunlight, windows, or lamps can otherwise make people and vehicles hard to see.
Electronic image stabilization
Electronic image stabilization can reduce the effect of minor vibrations in the camera mount.
That can give a steadier image, for example in windy conditions or with vibrations from traffic and machinery.
Efficient video compression
H.265+ reduces the need for storage space and network bandwidth compared with older video formats.
The camera also supports H.265, H.264+ and H.264, so it can be used with many different recorders and platforms.
Local storage on microSD card
The camera supports microSD, microSDHC, and microSDXC cards up to 512 GB.
That means you can save recordings directly in the camera, either as primary storage in a smaller installation or as backup if the network goes down.
ANR in case of network failure
With ANR, the camera can store recordings locally if the connection to a compatible recorder is temporarily interrupted.
When the connection is restored, the missing recordings can be transferred to the recorder.
NAS support
The camera can save recordings to compatible network storage via NFS or SMB/CIFS.
This makes it possible to combine memory cards, network recorders, and NAS according to the needs of the installation.
PoE or 12 V power supply
The camera can be powered via PoE or 12 V DC. With PoE, both power and network run through the same cable.
This makes installation simpler, since a separate power supply does not necessarily need to be run to the camera.
Protected against rain and dust
The IP67 rating means the camera is protected against rain and dust and can be used outdoors.
The camera can operate at temperatures from minus 30 °C to 60 °C.
Extra corrosion protection
NEMA 4X protection gives the camera better resistance to corrosion than standard models.
That is an advantage in humid environments, coastal areas, and other installations where the camera is exposed to tougher conditions.
Metal housing
The camera’s front, housing, and bracket are made of metal.
This provides a solid build for both indoor and outdoor mounting.
Typical applications
This is a small bullet camera that mainly suits private homes. However, we always recommend a turret for outdoor use, as it is very robust.
Compatibility
Compatible Hikvision accessories can be found under the Accessories tab.
