Can you run full time off a power supply plug in to the wall

Yes, this Remote Access Microphone can be plugged in for continuous operation.

If I hide this in my work office before I go home (5 to 10 miles away) will it record and would I be able to hear in real time on my phone? Also, if I'm not in my office,with just my phone can I turn it off and on?

Great question! This device will connect to the internet wirelessly. Once connected it can be accesed from anywhere using the app. (10 miles or another country!). When you are present and dont want to record, you can simply turn off the voice recorder manually.

Can I access voice activated recordings with my phone remotely, or can I only hear things "real time"?

Thanks for asking! This wifi access voice recorder lets access previous recordings and listen live. Please do note that playback through the app is greatly impacted by internet speed at both the recorder and your device as well as file size. For a more seamless experience we do recommend manual access to recorded data.

If the recorder is in a different location then you will it still work with live audio if it’s not connected to a wifi ? Or the WiFi is only used to connect the recorder to your app and for listening live ?

Thanks for reaching out. This remote access voice recorder requires connection to a wifi network that must be located in the same physical location of the voice recorder. The wifi connection must be available at all times.

What are the dimensions? Does the charging cable connect to 5V (i.e., USB), 12V, or wall outlet (120/240V)?

Thanks for reaching out! This voice recorder is a 5V unit with a USB port. It includes a USB cable so you can use a cube to plug to an outlet anywhere around the world. 
The physical approximate dimensions are: 2x1x0.5 inches.

Can I use WiFi connectivity and my iPhone to remotely turn this device on an off.

You can use home, office or dedicated hotspot wifi networks to connect this remote access voice recorder to the internet. Once connected you can manage recording and other features remotely from anywhere.

Can i stream the live audio from this device to my smartphone? In other words, if i want to hear in real time what my kids are saying while I'm at work, will this device support that functionality?

Hello there! The answer is yes. Please note that you need to have wifi at home in order to operate and remote access the live sound monitoring device.

Is this 5g capable? If found is it easily accessed? Mac compatible?

Thanks for asking! This remote listening device is not 5G compatible. You will need to use the standard 2.4 band in order to connect to your wifi. The App is found in the apple store. While it is meant for mobile device use, many MAC users can easily download the app and run it from the MACs.
