Newest Design WH-300 4G GSM SMS Contrller alarm with 2 digial inputs

THE WH-300 4G GSM controller is designed to remotely control a relay output on an
authorised incoming call. The unit will check the database of allowed users, reject the call
and only switch the relay if the user is on the authorised list.
THE 2 alarm inputs can also be used to detect any kinds of switched event such as an
alarm activation, door contacts, PIR detector, gate held open etc. The SMS can be
customised. The unit will send a customisable SMS notifcation to up to user phones on the
detected activity.
WITH superior reliability, configurability, easy remote management and 7-day phone
support, the WH-300 is not the cheapest available but it is most certainly one of the most
fully featured and reliable GSM remote control systems available.
