IP camera Hikvision DS-2CD2043G2-LIZ2UY/SL(2.8/4mm) Model: DS-2CD2043G2-LIZ2UY/SL(2.8/4mm) Application. 4 MP AcuSense Smart Hybrid Light tube network camera with motorized adjustable lens; 2.8/4 mm lens in one design, point varifocal type (with variable focal length); Corrosion-resistant design (NEMA 4X) increased reliability; Smart Hybrid Light integrated IR illumination and white light, 3 lighting modes; Crystal clear sound thanks to two microphones in a matrix arrangement (Arrayed Dual-Mic); Classification of people and vehicles based on deep learning algorithms; Water and dust resistance (IP67); Hikvision Active deterrence Application SMB segment (small and medium businesses). For companies in the SMB sector, cameras with active deterrence are a very practical solution. They allow the protection of objects without the presence of physical protection,; they ensure an immediate response to the intruder, the light and sound signal can discourage action before the event occurs,; thanks to the detection of people and vehicles, the system sends notifications in real time, which shortens the reaction time of the owner or security services,; they reduce the number of false alarms, the system knows when it is a real threat (person/vehicle), and when, for example, it is leaves in the wind or an animal. ; A camera with active deterrence can be used, for example, in: warehouses, company parking lots, loading stations, company halls, shop fronts, company headquarters, i.e. where protection is needed without the constant presence of personnel.
