Hi all, I am recently new to the forum and looking for any advice or help some of u can give. I recently purchased a “Sannce" dvr with a 4 channel or I call them 4 cameras with a 1tb hardrive. I have installed the cameras and I have it ran to my phone but the ? Is how am I protected?, and does anyone have or installed one of these that are familiar with them or someone give me feedback on wether I purchased a decent system. Cause the manuels r a joke and I basically hooked it up finding info out thru ppl or reading and gathering info on th internet. But I don't understand how the recording works and sometimes when I mash some keys on the dvr remote my tv will turn off or turn the volume up or display the input or menu options on the side. But any answers to these or basic feedback would b greatly appreciated. Thanks!!!!!
