The role of these stations is to detect any suspicious activity as it happens and respond accordingly.

Real-time alerts are critical for effective surveillance. When something out of the ordinary occurs, such as an unauthorized person entering a restricted area, the system sends an alert to the monitoring station. From there, security personnel can take immediate action to prevent potential threats or criminal activities before they escalate.

Remote access: With remote access capabilities, authorized users can monitor camera feeds from anywhere with an internet connection.

This feature allows business owners or managers to check on their property even when they’re not physically present.
