HAC-EW2501-0140B

The DH-HAC-EW2501 camera is a modern device used in video surveillance systems, belonging to the groundbreaking Panoramic series by Dahua. The camera is designed to monitor wide areas and captures videos using a 1/2.8" 5MP Progressive Scan CMOS sensor. The footage is enhanced with the presence of starlight sensitivity, WDR, 2D / 3D NR and a 1.4mm fisheye lens. In addition, the camera is accompanied by an infrared illuminator with a range of 10m and a microphone for 24/7 surveillance.

We present the HAC-EW2501, a perfect security solution for each property. This high -quality safety camera has 1/2.8 "5megapixel CMOS converter with progressive scanning, a panoramic fisheye lens and a maximum speed of 20FPS@5MP. It also contains a built -in microphone and offers advanced functions such as 120DB TRUE WDR, Starlight, 2D & 3D No. I Max. Ir Length 10m, Smart Ir. All this is powered by DC12V, thanks to which HAC-EW2501 is an ideal solution of all-in-one safety. Provide your company or home thanks to HAC-EW2501.

Fisheye camera application

Dahua DH-HAC-WIN2501 is a panoramic HDCVI camera, whose properties make it an advanced, indispensable element of simple monitoring solutions. They will successfully implement the need to expand any monitoring system. The possibilities of recording the image in a resolution of 5MPX and the use of an efficient image converter meant that the camera adapts to the complex observation environment as much as possible and will allow the implementation of precise video protection of secured places.

Wbudowane menu OSD

---

The camera stands out from the competition with a quick and easy configuration process of the entire 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. This possibility is a very convenient solution that ensures comfort of service and high work efficiency. Access to the interface itself can be initiated thanks to the COC (Control Over Coax) function.

Panoramic fisheye lens

---

The camera is equipped with a panoramic Fisheye lens with factory focal size. The configured 1.4mm lens allows you to instantly turn on the camera into the monitoring structures.

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.
