HAC-B1A21-0360B Cooper Camera

The DH-HAC-B1A21 is an Analog HD Cooper series bullet system camera manufactured by Dahua. It uses the latest 1/2.7" 2MP Progressive Scan CMOS image sensor, allowing for recording in 2Mpx resolution. Various adjustment settings are included, including DWDR and 2DNR, which guarantee optimal image quality. Additionally, it is equipped with a 3.6mm lens and an illuminator 20m infrared range for 24/7 surveillance The camera is also IP67 rated, making it resistant to harsh weather conditions.

We present HAC-B1A21, an innovative monitoring camera that is perfect for use in any safety environment. This camera provides a maximum of 30 frames per second with a resolution of 1080p, which allows you to get clear, sharp images. It can also be switched between CVI/CVBS/AHD/TVI to ensure compatible compatibility. Contains a 3.6 mm permanent lens (optional 2.8 mm and 6 mm) for optimal covering, and its max. IR length is 20 m with smart IR for excellent visibility at night. In addition, a camera with an IP67 class has been designed as resistant to dust and water, which makes it ideal for external applications. Finally, HAC-B1A21 is easy to install and use thanks to the 12 VDC input.

Multi-system technology

---

The Dahua camera belongs to the innovative series of devices that allow you to work in four different monitoring systems - CVI, TVI, AHD and CVBS. This solution is extremely convenient, especially because of the possibility of connecting the camera to completely independent end devices, working in any of the mentioned systems. The work system is changed via the camera OSD or UTC PFM820 controller.

Menu OSD

---

The HAC camera is distinguished by a fast and easy configuration process of all settings and modifications. The device is equipped with an intuitive, transparent OSD menu, which allows you to instantly change the available image capture parameters directly from the level of the synchronized recorder by appropriate calling. The modern screen menu guarantees a remote modification of the monitoring system settings without the need for physical interference with a single camera. Access to the interface itself can be initiated thanks to the COC (Control Over Coax) function. The camera serves 11 languages ​​for the OSD menu (Chinese, English, French, German, Spanish, Portuguese, Italian, Japanese, Korean, Russian and Polish).

Illumination of the area

---

The camera is equipped with infrared illuminator with a range of operation of up to 20 meters. The LED provides an infrared light bundle that illuminates the monitoring area at night.

Comparison of focal length lenses

---

The camera also has a comparison of 3.6mm focal lenses, which allows you to instantly include in monitoring structures without having to undertake additional assembly activities.

IP67 tightness class

---

The high quality of the housing confirms the provision of the IP67 security class with the device.

Protection

---

Input voltage tolerance is ± 30%, allowing the use of cameras in the conditions of unstable power supply. In addition, the camera has a security of up to 4 kV.

Noise reduction system - 2D NR

---

The noise reduction system allows you to maintain image transparency in a situation of variable signal strength level. In practice, this function protects the recordings against the occurrence of so -called The smoking effect and allows you to maintain detailed and crystal clear video recordings.

DWDR - Digital dynamic range

---

Technique based on software, which allows easier identification of objects located in the dark areas of the image by using gamma correction (retains natural shadows and lighting - as opposed to a simple change in brightness or contrast). DWDR is a cheaper and worse WDR variety.

BLC - Backlight compensation

---

The function allows you to eliminate the resulting effect when the camera is directed towards a strong light source, i.e. when the first plan becomes dark and not legible. Compensation consists in brightening the first plan, unfortunately also at the expense of the background, which also becomes brighter. Generally, the function improves image quality.

HLC - High light compensation

---

The algorithm detects image points that are strongly lit and then masks them enabling effective observation. HLC mode is extremely useful when observing underground parking lots. It allows you to read the license plates numbers that are covered with "bright stains" from the headlights.

Smart lighting function

---

The intelligent lighting function allows you to change basic image parameters, such as exhibition, contrast or brightness. The signal processor analyzes the image on an ongoing basis and immediately after detecting the x -ray reduces the power of the infrared illuminator. Thus, the image becomes more pronounced and the x -rays disappear.

Privacy masks

---

Using the characteristics of the camera with the function of privacy zones, it is real to adapt the method of functioning of the observation system to the spatial specificity and safety requirements of a specific installation site. Thanks to the privacy mask system, it is possible to freely determine the image fragments that will be excluded from the video supervision.

AWB - Automatic White Balance

---

The intelligent system of automatic white balance enables reproduction of video material while maintaining the natural proportions of white shades. The AWB function analyzes the camera's work environment and automatically adjusts the image parameters.
