This is an automatic, single line, telephone recorder that not only records both incoming and outgoing calls on the line but it records the time and date of those calls and also the number dialed and the incoming callers number (if caller ID is available).

Simply connect this to any extension on the line and insert a compatible micro SD card (supplied with 2Gb) and you are ready to go.  Because of the fact that it records onto SD cards (up to 8Gb supported) you can simply and quickly remove recordings without interrupting the status by replacing the card whenever necessary or possible.  An 8Gb card will store an amazing 300 hours of telephone conversations.

This unit has its own internal power source which is recharged by the phone line as and when it is not being used so that it can keep itself going for weeks, months and even years and even if there is going to be excessive daily use the included power supply can be used.

There is also encrypted password protection which means that if it is discovered and the card analyzed no one will be able to hear any of your recordings, this is only possible with the correct password.

For playback you simply remove the SD card, connect it to a computer and with the supplied software listen to the recordings in your own time.
