Specification:Professional alarm kitRecommended degree 2Ethernet and GPRS communication868 MHz wireless jewelerUp to 100 wireless devicesMobile application and PC softwareAjax StarterKit wireless alarm kit:- 1 central hub- 1 MotionProtect alarm- 1 DoorProtect alarm- 1 SpaceControl remote controlWireless alarm center for professional installations, both residential and commercial. Communication is via Ethernet and / or GPRS. The supervised bidirectional link of detectors and accessories is made by radio frequency following its own protocol, jeweler, in the 868 MHz band, obtaining grade 2 certification.The wireless link achieves high reliability thanks to its advanced Jeweler protocol with high security AES encryption. The exclusive system of instantaneous and intelligent supervision detects the inhibition of the signal by identifying the determined time of inactivity and in turn allows to reduce the maintenance costs succeeds in extending the use of the battery life of the detectors without compromising the safety . The wireless signal is able to cover distances of up to 2 km in an open space. It also includes features to facilitate installation, such as Smart-Bracket or simple connection of detectors to the alarm system.It allows up to 100 wireless zones, which allows these devices to be grouped up to 9 different groups, on the different actions of arming, partial arming or disarming can be carried out. These Ajax wireless devices have different possible configurations, such as 24 hour zone, zone with entry or exit delay ...The AJ-HUB has an AC 110-250 V power input as well as a rechargeable backup battery that lasts up to 15 hours.Ethernet communication is its main advantage for remote access, both for the user and for the installer, as it allows its connection through the software for PC AJAX PRO Desktop and mobile applications for iOS and Android Ajax Security Systems (end user) and AJAX PRO: Tool for Engineers (professionals). With these applications, it is possible to configure the entire system, manage users and their permissions, add devices, group them into rooms and change their configuration. Using the cloud is compatible with dynamic IP addresses without the need to open ports. Ajax users will enjoy many benefits as you can receive reliable and instant notifications in both desktop software and mobile apps.In addition to the Ajax alarm system, from the mobile app, you can add up to 10 IP cameras or video recorder channels to be able to check the live video feed.
