Alarm system via landline phone and PIR motion sensor. A sensational anti-intrusion telephone system!
TEL-ALARM is a telephone, a motion sensor, and a microphone at the same time and you can use it as an ordinary landline telephone, until you decide to treat it as a monitoring system. Simply enter any telephone number you choose and turn on the motion sensor.
Once the sensor is on, the telephone is ready to detect any intruder entering the room and call you at the number you dialed in. Upon answering that call, you are able to listen in to the sounds in that room via the amplified microphone. The listening time is about 30 seconds, then the phone disconnects and instantly starts up again to detect.
TEL-ALARM works with any landline phone device and it is simply connected to the line itself which acts as a communication channel for the alarm.
The TEL-ALARM circuitry requires an AC adapter (provided) to be plugged into any standard 110V wall outlet.
The absence of this power adapter doesn't cause any serious problem but only a lower power. You can connect your TEL-ALARM to any existing phone line like another ordinary phone.
The TEL-ALARM motion sensor is Passive Infrared Technology (PIR). The passive infrared sensor detects changes in the room's heat signature due to occupant motion. The range is in excess of 30 feet at which point the width is about 20 feet, creating about a 45 degree wedge beyond the sensor origin (see the picture on the right).
The hidden condenser microphone is amplified to insure that sounds are heard in the best way.
