is a very economical unit. If you only need basic security, this is the one for you. Easy installation; basic protection; no monitoring fees; all encompassed in 1 unit will call 5 designated numbers(phone, mobile, pager) automatically as soon as it detects an intrusion or the early stages of fire, and inform the receiver of what is being detected by way of 2 different recorded messages('Intrusion', 'Fire'). In addition, you can monitor the surrounding area by activating the microphone by a phone call, even from a distance. If you are certain that there is an intrusion, you can scare the burglar away with your own voice, through the speaker on the device. This item can be armed, disarmed, reset all by means of a telephone. You can even program in your cell phone number.
Note: The SSC-210 is a single unit model which connects to your existing telephone line.
