CCTV camera-sky

ask from the company you bought from, that is better... is there any manual for you to operate? regards, Sky

yes, that is the difference between Hybrid and non Hybrid DVR, what matters most is the camera, ip or analog. but there is also 3 in 1 intelligent IVR, DVR+HVR+NVR, with video analysis functions. do you know about this? thanks, sky

DVR 8204? you even don't have a drive software? usually DVR can both use IE or firefox i come from China, but i don't know this item No.

Never used Dahua cards so I can not help. But I have installed and sold quite a few Hik cards, and I have never had a single one fail or give me problems, so I do wonder why anyone would think that they are "very badly crafted cards"... both hik and dahua products sell well abroad

yes, if there is a camera in your house, it can see you, can you also can see it. even if it's a hidden camera. just take easy

NVR means network video recorder, for wireless installation. as for DVR, now SVR(standalone DVR) is common used, D1 resolution, record playback. both have its advantages. But if used in office or buildings, DVR is better.
