I've been having this camera on our construction site for a few months now.
Battery - stayed at 100% since then with the help of solar panels.
Nightvision - clear without almost no light in my area. Built-in light can be useful too.
Mic - The 2-way audio works quite loud (much louder than a speakerphone on a mobile).
Data usage: I got a 30GB plan for 90 days. With daily camera viewing several times a day it hasn't used even 1GB yet. I think more power could be used if we use the built-in light and record many videos. For live viewing, data usage is very minimal.

I wouldn't recommend if you want to move this into a WiFi network later, as this works only with a SIM card.

This battery is a marvel! I do a lot of professional video shooting and the shots that need to be taken are - very often - far from power sources... So I plug my camera into a fake D-TAP battery, my lighting back-up etc... This battery has not one, but two D-TAP outputs, a PB interface, a USB-C port (PD Fast Charge) and a USB-A port. In short, everything you need for mobility and of course a V-Mount attachment to put it on standard supports. So it doesn't have a very small format if we compare it to classic power banks for the same capacity but on a camera it fits perfectly (and it's not exactly the same use). It makes my shooting so much easier that even when I have access to power, I use the battery to avoid running cables. I knew K&F Concept well for the quality of its photo filters, but the same care is given to this battery.

This wireless outdoor surveillance camera works where Wi-Fi and power are not available. With a NANO SIM card, the camera is only activated when it has detected a moving object. This reduces data consumption.
