Audio Surveillance Equipment
The purpose of an audio surveillance device is to enable you to secretly listen into and record conversations that take place at a particular location or on a particular telephone line. These devices are divided into two main types:
1. Wireless i.e telephone transmitters
2. Wired devices i.e recorders, telecorders, wall contact microphones, wired microphones etc.
Telephone Surveillance Equipment
The most commonly used telephone surveillance equipment is transmitter. Clearly monitoring both sides of a telephone conversation, the discreet range of Phone Transmitters are easily installed on a telephone line, in a socket, or in the instrument itself. Telephone Transmitters are surveillance transmitters that become operational when the telephone is in use and give no indication of their presence to the telephone user.
Another most commonly used telephone surveillance equipment is telephone recorder. It connects to the phone line, your tape recorder's microphone input, and the recorder's remote control jack. It senses the voltage in the phone line and begins recording when the line drops to 5 volts or less.
Counter Surveillance Equipments
Counter surveillance is the practice of avoiding surveillance or making surveillance difficult.
