I have read all the threads and still have
I am new to this and have a few questions. I have a Q see analog 4 camera system now and want to upgrade. with IP cameras if there is a storm and your internet goes out do they still work with a monitor but no remote viewing ? are IP 4mp cameras that much clearer than IP 3mp cameras? the ones I have been looking at are 16 Channel HD Digital Security System with 8MP HD IP Bullet Cameras QC8816-8AU-3 or the Q-See 3MP HD 1080p Complete IP Surveillance System - 8 Bullet Cameras & 16 Channel NVR with 3 Terabytes and I quess is Q SEE ok ? it is the only brand I have ever used and I am not sure of the quality of the other brands I am not stuck on any certain brand Thanks! |

Internet failure will have no effect on the camera to dvr connection (they are wired to the dvr, and even if they were wireless, they would still operate on your wifi network, same as a printer, you wouldn't be able to Web surf but could still print from your computer) but you would lose Internet based remote viewing.
MP is just a measure of pixel density. Ever see a picture someone took with a digital camera and had enlarged to the point you could make out little dots comprising the image? That's pixel density. Think of it like this, on a 3mp image of your living room if it was a perfect square it would be a grid of 1,732 dots wide by 1,732 dots tall. On a 4mp it is 2,000 dots by 2,000 dots. Extra pixel density means 2 options, more detail, or a larger covered area at the original resolution (you can have the same amount of detail in a larger area). It is diminishing returns though, the difference from 1mp to 2mp is pretty huge, from 3mp to 4mp, not so much, your call. (As an example, 1080p television is about 2mp, to double the detail and go to 4k, it's about 8mp. See the problem?) |

See the problem?) great response. for the last question re: Q-See and brand quality, there a million choices much like another topic we discuss here often. I have used q-see analogs and they get the job done. With the mass amounts of product out there, you basically get what you pay for. I used cams from q-see to 5mp avigilon and many in between. I like the turn-key-ness of the two systems there, but if it were me, I'd be more apt to build it myself by selecting individual cameras for individual needs, and build the PC with a dvr software. |
