Is battery life being used when not recording? Or will I have to charge every single day? Or can it last a couple days if not recording a lot?
Thanks for reaching out! For this voice recorder the battery is always active when in the ON position. Voice activation pertains to the recording of sound, however your battery will run for up to 23 hours and then will need to be recharged. If you need more operation time, you can plug the recorder to a power source (outler or external battery) and record. There are other recorders that will have longer battery life, however you may get less recording time.
Can this be used without being seen - if its hidden somewhere?
Hello! You can definately use this voice recorder discretely. It is small and light weight so you can get very creative on how you hide it. The battery will allow you about 23 hours of operation and if you can find a discrete place to connect to a power source (like with a wall charger ) you can record for as long as you have memory, which will be at the very least 1 week.
