Security that can respond actively
Video surveillance and an alarm system do not have to serve only for reviewing events after the fact. Depending on the capabilities of the installed equipment, a particular event can trigger a notification or a linked function: switching on the lights, activating a siren, changing the position of the blinds or displaying information in the user interface.
Where the chosen equipment supports it, modern cameras and security systems can send a message or push notification with an image when a suspicious situation is detected. Such functions should be defined carefully so that responses are useful and predictable, without unnecessary alarms. Integration is an additional layer that links security equipment, but it does not replace a properly designed core security system.
