Bluetooth webcam
The camera does the trick, no one is able to see the hidden camera and thinks it's a handset for a mobile phone. During the day, the camera records clearly and the details from the cards are for reading an important matter.
For a hidden camera, I rate it very good.
The biggest disadvantage is the lack of a signal warning in the handset that the webcam is discharged, which prevents further recording. If there was a signal, you can immediately hear in your ear that the webcam is not working and you don't know when the camera turned off, which is difficult in important matters and you can lose a lot.
Audio recording sound poor if you are indoors within 2.5 meters. The farther, the worse and even not understandable conversations. Weak or low microphone sensitivity and not all conversations can be understood.
Poor recording quality in the evening.
The recording time of the webcam is about 40 minutes and sometimes even shorter with different charges.
