Descrizione
Specifications Dahua Pinhole IP 2MP 2.8mmvideo surveillance camera IPC-HUM4231S-L5-S3 is widely used in hidden settings or small environments, such as banks and advertising screens or billboards. This pinhole camera realizes higher encoding efficiency than H.265 and H.264, provides high-quality video, and reduces storage and transmission costs.
With advanced image processing technology and the optics used, Dahua Starlight technology can provide clear and colorful video even in low-light environments. Dahua IPC-HUM4231S-L5-S3 uses various security technologies including security authentication and authorization, access control protocols, secure protection, and encrypted transmission and storage. These technologies also enhance the camera defense against external cyber threats and prevent suspicious programs from accessing the device.
