Hi, I'm looking for a hidden cam with power supply operating 24/7 reliable and with ftp and ddsn features.
I have a lot of doubts.
I tried some cameras in the past but for wireless ones sometimes the audio signal cuts off.
I've seen there are a lot of cameras on market but without brand and I don't know which I can trust on it.
Actually it would be enough for me only a microphone without video but it seems to me that there aren't devices with only audio signal.
Maybe it would be better only...
