Maybe all of you who have been looking somehow into surveillance know that usually investigators like voice recorders rather than bug transmitters. I suppose that most of them believe a bug transmitter may fit investigational needs in a better way. Anyway let’s see here the difference between the two kind of devices.
When it is better using a bug transmitter
Certainly one of the biggest problems found in bug using concerns power supply, I mean giving the device a continuous power especially if it must be used for many days straight. Think for example to those situation in which you have to go back and retrieve the transmitter in order to change batteries. Thus in such case it would be best to connect the bug to the mains so that you will not have to worry anymore about it. Are you agree? Another benefit is to provide real time monitoring by using a GSM bug as well as to easily hide the transmitter thanks to the circuit miniaturization. Hence no time or distance limits...
