Spy Telephone Voice Recorder monitoring on fixed - line communications

This high technology product is a recording equipment specially designed for monitoring on fixed-line telephone communications. Besides recording the conversation contents of the incoming and outgoing calls, it can also record the corresponding telephone numbers, replay the record content with a special player on the PC and check the number information. 
By using a micro SD card as the record storage medium, this equipment can record and work independent of the PC. In a  micro SD  card with the capacity of 1G, about 37 hours of conversation can be recorded. 
The recording files can be encrypted and cannot be replayed until the correct password is entered, which greatly increases the confidentiality of the recording files. With the simple and convenient file playback retrieval operation, the recording files can be selected for playback according to the time order or telephone number order. 
The most prominent advantage of this product is that it can realize monitoring on the remote terminal and duplicate recording files in a remote way. 
Another advantage of this product is that no external power supply is required and the product can work by the built-in lithium battery which is recharged through the connecting telephone line. In this way, the embarrassing situation that the product cannot work in case power failure when the external power supply is used can be avoided. 
This device also has the auto-answer function. With a small volume, light weight and disguised appearance, it is suitable for monitoring on fixed-line telephone communications by special users
