Average Reviews:
(More customer reviews)I was looking for a DIY alarm system that uses GSM dialer since I don't have a landline. The reviews seem to be good for these kind of systems from AAS, except from a few reviewers. I decided to go with the most expensive one because I wanted to have the extra sensors, wireless sirens, and remote keypad. Here are the pros and cons:
Pro:
1. The instruction manual is very easy to follow. You can request a soft copy of the instruction manual before you buy the system.
2. It is a two-unit system. One is the main unit and the other is the GSM dialer. This design is more flexible. If I decided to get a landline later, I can use the main unit to connect to my landline.
3. Communication with the seller is easy and quick.
Con:
1. As other reviewers mentioned, the delay time to arm the system is in minute increment. Note, if you use the remote keyless to arm the system, it arms the system immediately. The delay only works if you arm the system from the main unit.
2. When alarm activated, the sensor number that triggers the alarm only displays on the main unit for 30 seconds. Then, it disappears. I wish that it stays there until I erase it so that I know which sensor triggers the alarm.
3. Not cheap.
Tip: The double sided tapes on the sensors do not hold well. I use velcro instead and it works better. This will allow me to easily remove the sensor from the door/window to change the battery at a later date.

The GSM Terminal replaces the typical landline and works like a cell phone. As most mobile phones utilize a SIM card to wirelessly transmit through the cellular network so does the Cellular GSM Terminal. SIM cards may be purchased as a prepaid card or on a monthly basis from your cellular carrier such as AT&T and T-Mobile. The GSM Alarm System comes with a built-in backup battery pack and the GSM Terminal has the option of a UPS Back-up Battery power adapter to maintain continuous fuctioning in case of power outages and interruptions. The GSM Alarm does not interfere with Wi-Fi applications. The Cellular Alarm System will call to mobile phones, landline phones and broadband phones. The Cellular Alarm System comes with an integrated Automatic Dialer with a stored memory capacity for six phone numbers[up to 21 digits in length] and for a recorded message. When the Wireless GSM Alarm System is triggered. it will call each of the pre-stored numbers and deliver the pre-recorded message. When the system calls, the receiver will be able to listen and monitor the premises through the phone.
