Dahua IPC-HFW3241DF-AS-0280B-4G – WizSense Bullet IP Camera 2MP, IR 50 m, 4G

The Dahua IPC-HFW3241DF-AS-0280B-4G is an outdoor WizSense bullet IP camera designed for professional video surveillance at locations without access to a wired network. Thanks to its built-in 4G modem, the camera operates completely autonomously – all that is required is a SIM card and 12 V DC power. AI-powered detection functions (intrusion and tripwire detection with human/vehicle classification) minimise false alarms and ensure reliable protection in demanding environments.
