I have the model before this one I think.I use a Telstra data sim card. (My choice of provider) you can pay a years worth for around $130 a year or monthly at $30.I got the 40 gb card. In two years I’d be lucky to have used 10gig. But the more you use it the more data you need.It will operate live to the app if it’s placed in an area where your phone can get data reception. (Not the same as call reception where it will operate with one bar) For example, when choosing a location to install camera,use your mobile phone to choose a location where the best DATA reception is.Like if you can play YouTube your cam will work too.It’d say a spot where you can get at least 3 bars.It will work off 2, but May cut in and out at times.It charges off solar panel. Which hasn’t failed me even on cloudy and rainy days for weeks on end. So if you have any trouble shooting issue to do with battery power it may be a faulty panel because they will work and charge the cam under the poorest of conditions.With age, the Antennas on mine fell off. They got brittle. But the camera still operates and connects to wifi in the paddock anyway.Mine has survived 3 major storms. Of 200 Kim winds, hail and rain.It’s survived the sun. And the worst elements imagined. It still going.Due to being Chinese made and not entirely secure privacy, use camera in places where surveillance is not encroaching on your most private areas yeah. Great for farms and Locations you need to keep an eye on activity while you’re off location.The app works fine. You can view and use it easily on your phone.Picture quality is up there with the best.Night vision is good too.Has two way communication via camera, so it you see someone walking past your camera you can talk to them via the app.The camera swivels around almost 200 or more degrees. So you can see all around the place. You can zoom in from far away, but off course it may pixelate from long distance.Overall for the price, it’s good value for basic surveillance.
