Specifications<\/div>\n
Dahua Pinhole IP 4MP 2.8mm – video surveillance camera IPC-HUM4431S-L5 is widely used in hidden settings or small environments, such as banks or advertising screens. This pinhole camera realizes higher encoding efficiency than H.265 and H.264, provides high-quality video, and reduces storage and transmission costs.<\/p>\n

With advanced image processing functions and the optics used, Dahua Starlight technology can provide clear and colorful video even in low-light environments. Dahua Pinhole IP 4MP 2.8mm IPC-HUM4431S-L5 uses various security technologies including security authentication and authorization, access control protocols, secure protection, and encrypted transmission and storage. These functions also enhance the camera defense against external cyber threats and prevent suspicious programs from accessing the device.<\/p><\/div>\n
