My power cable was removed by accident from the DVR and once powered back on, the cameras are not showing any images as well as all of my data stored within the hardrive from the past, has been lost. I am not sure why this has happened and this is not the first time. I previously owned an older model of this DVR and again once switched off, the problems then start to occur and eventually it failed to function at all so had to buy a new one. Please can I get some assistance with this matter. Also, I am working from within the UK, just for reference.
