AHD cameras are capable of capturing high definition video surveillance at 720p and 1080p resolutions. AHD camera use coax cable to transmit HD video to DVRs.
 

WDR (Wide Dynamic Range) is used for capturing images of objects surrounded by a strong backlight, while still keeping the background visible. A typical use is capturing scenes indoors that have large windows in the background with lots of sunlight. WDR would enable you to capture both the indoor and outdoor/background scene clearly.
 

It depends on your recording setting, ex: resolution, frame rate, video quality..etc. You can go to our Everfocus website-> Support -> HDD Requirement calculator to get estimated storage number.
 

Launch MobileFocus App, then go to help of bottom menu bar, click User manual to read it. There are instructions for how to use MobileFocus

Check if the power supply system is properly connected and power cord and power cables are securely connected, and if something wrong with the HDD interface. Or you may check if your HDD is supported by referring to the specifications or descriptions.
