Description
DH-HAC-HFW1500TL-A-S2 is a modern tube camera, prepared to work in Analog HD vision systems. It is part of the groundbreaking Lite series by Dahua, responsible for 24/7 supervision of places and facilities. It has a 1/2.7" 5MP Progressive Scan CMOS sensor, capable of delivering 5Mpx recordings. Starlight, DWDR, and 2DNR technologies are features included in the device that improve image quality. It has a 3.6mm lens and an infrared illuminator with a range of 80m, which guarantees constant surveillance, additionally includes a microphone and is waterproof according to the IP67 specification.
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).
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.
