Specifications<\/div>\n
\n

Dahua Pinhole IP 2MP 2.8mm – video surveillance camera IPC-HUM4231S-L4-S3 supports intelligent functions, such as tripwire and intrusion, and provides clear details in high contrast brightness environments. The light and dark area can achieve sharp video even in high brightness or backlight shadow environments. Dahua IPC-HUM4231S-L4-S3 allows \u00b130% input voltage tolerance and is widely applicable in outdoor environments with unstable voltage.<\/p>\n

Dahua Pinhole IP 2MP 2.8mm video surveillance camera also uses a number of advanced features including security authentication and authorization, access control protocols, trust protection, and encrypted transmission and storage. These technologies improve the camera’s defense against external cyber threats and prevent malicious programs from accessing the device.<\/p><\/div>\n
