Among the products offered by the Chinese company JosIndustrial there are GSM and fixed line alarm systems. End of December 2010 I ordered the system J-h830gsm2, system which was delivered to me beginning January 2011. With this system, theoretically guaranteed for one year, I met many of the problems that the company JosIndustrial do not take into consideration in the sense that the Customer Support representative does not even reply to the E-mails the emails I have sent. The major functional problems encountered are the following:
- A French version of the system is announced and was shipped, but only an installation manual in a very bad English language was part of the shipment
- The product does not conform to the accompanying manual. It is therefore impossible to install it by following the procedure described in this manual to the letter.
- The product is supposed to transmit SMS messages, characterizing the detected alarm, through the GSM network to a pre-recorded mobile number. The initialization of this function, although recognized as good by the system, does not give the expected effects; the pre-recorded number is called, but no SMS or message is transmitted.
- The product is supposed to convey a message of pre-recorded alarm through the fixed telephone network, to pre-recorded fixed or mobile phone numbers. This function is unusable because before listening to the message the called party must know that * has to be dialed when the called party, who may be a neighbor, does not even know that it is an alarm system that calls or if a friend is calling. It will therefore hang up and think that it is an error in numbering as nobody seems to be on the calling side..
- The system can be controlled remotely by SMS or a line fixed message. This requires to specify after how many rings the system must accept the call. Unfortunately, this number of rings is the same for the Alarm box specific GSM number and for your fixed line number. The consequence is that: either the alarm box accepts the call to late and the calling administrator is connected to your call answering machine that doesn’t understand the commands that are for your Alarm panel, or the call is answered to soon and the calling party, connected right away to the Alarm panel that sends the password request message, will not understand why and what password he/she has entered before talking to the called party; in this case the fixed line can’t be shared anymore between the Alarm system and the family. The only way to work around this problem is to subscribe to a second line dedicated to your alarm system.
- There are other functions that don’t work as specified in the system; we could bypass these functions by adding our own developed electronic circuits to Alarm system.
