Dahua Eyeball IP 4MP 2.8mm – video surveillance camera IPC-HDW2431T-AS-S2 features more efficient video decoding capability, which saves bandwidth and storage space. The Starlight technology on-board provides color images even in dimly lit scenarios. Dahua smart encoding technology provides high-quality video and savings in storage and transmission.<\/p>\n

The Eyeball IP 4MP 2.8mm camera captures vivid images even under the most intense contrast conditions. True WDR (120 dB) optimizes both overexposed and dark areas for perfect video. By adopting large pixel sensors and smart algorithms to process images, the camera provides unparalleled performance even in dimly lit environments. Dahua IPC-HDW2431T-AS-S2 Eyeball IP 4MP 2.8mm also supports advanced authentication, authorization and encryption technologies for transmission and storage to ensure data security, as well as smart video analytics features such as tripwire (line-crossing) and intrusion.<\/p><\/div>\n
