The dual sensor design allows for more flexible installation and easier adaptation to the required zones.
The free SmartZone mobile app is used for settings.
Suitable for monitoring homes, villas, factories, computer rooms, shops, hotels, office buildings, banks and many other places for possible intrusion.
