Why sirens?
A siren extends your surveillance system from being able to see to also affect and disturb unauthorised people. The aim of a siren is to intimidate unauthorised persons to the point of interrupting their intrusion attempt and attracting attention. As the siren is connected directly to an IP camera, it can be controlled both locally via your system and remotely if the system is connected to the internet. In addition, it can be activated automatically if your camera supports it.
