The i23S is an SIP voice intercom access control product developed specifically for industry users' needs based on VoIP phone technology, using standard IP/RTP/RTSP protocols for transmission. It well inherits the advantages of VoIP phones such as high stability and carrier-grade sound quality, and is perfectly compatible with all current mainstream SIP-based IPPBX/softswitch/IMS platforms. With an IP65 protection rating, it effectively prevents dust and water splashing. Integrating remote door opening, password unlocking, card swiping, and indoor switch control, the i23S offers high cost-effectiveness and serves as an ideal choice for customers.
