Grandstream's GDS3725/3726/3727 smart IP video door stations represent the evolution in access control and security systems, combining high-definition IP camera, IP intercom, and comprehensive access control system functions. With Full HD 1080p resolution, an advanced AI ISP image processor, and artificial intelligence-based behavior analysis capabilities, these devices offer precise identification up to 3 meters even in low-light conditions. They integrate 13.56MHz and 125kHz RFID readers, support multiple entry methods (PIN, IC/ID cards, NFC, BLE, APP, QR code), and feature IK10 vandal resistance with IP66 protection for demanding outdoor installations.
