PLEASE done waste your money. Maybe a good deal here and there but as the saying goes "You get what you pay for " I've had this system for a couple of years now and since day one I have had issues. The app sucks, the cameras just keep disconnecting. I purposely put my cameras out of reach and purposely hardwired the power so I wouldn't have to get to cameras to recharge batteries, but ALL I DO is have to get to the cameras to resynch them OVER and OVER and OVER and they never stay connected. Maybe a day or 2 if I am lucky. My cameras are ALL within 15 ft of DVR and without many walls or obstructions, I have a great router and wifi and yet they still disconnect all the time. Every time I look at my app, frozen or disconnected cameras, loading and loading. So basically useless cause I every time I need it for something it FAILS ME. I have called tech support several time and that is pretty much useless. Last time I called I got someone in Philippines that I knew more about the system than they did. I have resynched so many times that I just give up for a few months and then try again. I have checked firmware…etc. Most recently (this weekend) I took all my cameras inside near the DVR, resynch them all to the system, make sure all the settings I want are there, cameras working, can see them on app and monitor, I then take them one at a time to install spot and I walk literally like 10ft with no obstruction and it loses connection. I did a WIFI survey with ipads, cell phones, laptops and wifi signal is super strong. Its just these cameras and system are pure junk and waste of peoples money and time. I now have a system with 3 cameras, hundreds of dollars invested, hundreds of hours of my time trying to get it to work correctly and reliably and it is NOT working AT ALL. None of the cameras will stay connected at this point. Please do your research and find a different system so you dont waste your valuable money and most of all your TIME!
