Be notified rapidly of any event protecting your people, equipment, and facility with support multiple alarms for intrusions, tampering, timeouts, duress, and more.


With an internal storage battery through power supply means that even with outages your equipment remains operational. Even in larger power
failures, data can be saved permanently offering the ultimate protection and
archiving. Supports online upgrades and watchdog mechanisms ensuring operational stability.


Optiview’s CAS-4SA2 supports storing up to 100,000 users and up to 500,000 card-swiping records. With so many authentication and authorization user and recorders, no matter the size of the organization, or installed access control devices your data is always secure with multiple layers of protection.


Control access to an area in a way that allows only one door open at a time. Multi-door interlocking prevents a second door from being opened until the first door is closed and locked. This technology is perfect for clean rooms, and detention centers.


This technology allows your access control system to prevent a device from reading a specific card or code a second time until it’s left that area again first. This is seen at preventing nefarious access to an area by requiring entrance and exit access.


Require a specified group or select users to establish a sequence or pair to unlock a specified door or entrance.


Remotely open and unlock doors without the need of being on site. When connected to a security camera using our remote monitoring software, you can allow a security guard to review access before remotely granting access.
