Hikvision DS-K2M061 Secure Door Control Module

DS-K2M061 closes a well-known access-control weakness: if the lock wiring is reachable outside the secure area, the door can be opened by simply shorting the contacts. The module sits inside the protected perimeter and takes over lock control, so shorting the external line does nothing. It connects to and is powered by Hikvision access controllers and installs above a false ceiling or in a junction box near the door. A must-have where access control has to resist deliberate attacks, not just everyday use.
