Review the manufacturer-documented specifications for Hikvision DS-KIS621-S. Compare the system role, interfaces, mounting and power conditions using the exact model's technical table.
Product description
The manufacturer lists Resolution for Hikvision DS-KIS621-S as Main stream: 4MP(2688x1520P), 2MP(1920x1080P), 1MP(1280x720P) Sub stream: 2MP(1920x1080P), 1MP(1280x720P), 0.3MP(640x480P). Assess this specification alongside the component's role in the system; display, call and credential capacities are separate specifications.
Network protocol: TCP/IP, HTTP, HTTPS, FTP, DHCP, DNS, RTP, RTSP, NTP, IPv4, IPv6, UDP, WebSocket, WebSockets，ONVIF, SIP v2 (RFC3261). Check the manufacturer's model and interface compatibility when selecting the connected unit or module. Wire count alone does not establish IP or analog signalling; evaluate electrical connections and protocol conditions separately.
Power consumption: With Lock: < 20 W Without Lock: < 14 W. Plan installation and power against the technical table for this exact model. Interface support alone does not establish that an accessory, power supply or connected component is included; compare the package contents and installation documents.
