This review is from: Q-See QS408-5 8 Channel H.264 Smart Recording DVR with Pre-Installed 500GB Hard DriveCustomer review from the Amazon Vine™ Program (What's this?)
I bought my first q-see DVR (digital video recorder) about 3 years ago right here on amazon.com. It was known as a "PENTAPLEX" which meant you could do 5 things at the same time - record live video from multiple channels, backup the hard disk, view video remotely over the internet, view video locally on a TV set, and search through recordings to find out who took your recycle bin full of cans. Pentaplex and Triplex are names given as to how many activities the unit can do simultaneously.That unit is still running after driving the neighborhood drug dealers out of their rent free abandoned home (and having them arrested numerous times - it povided key evidence of license plate numbers, video of drug deals going down, spousal abuse -- you name it the police department got it. For that matter the PD could log in over the internet to check up on who was there if they wanted to)I live on a 2 block long road full of modern quiet 4500 sq ft homes, and across from me was a 60 year old 931 sq ft original house that had become the neighborhood drug hangout - a place to go smoke a bowl, ride your motorcycle through the front door of the house and out the back, to hook up with the homies, etc. It definitely did not fit in - the crime rate rose - the house adjacent to the drug house was robbed 5 times in 3 months. Both me and my next door neighbor installed MONITORED alarms and we formed our own neighborhood watch. His was a .357 and mine was a 9mm.The Q-see was instrumental in getting rid of the trash. It provided numerous photographic enlargements of license plates, video evidence used in court to convict the individual squatting there, and more 30 second drive by drug deals than I could count, happening every 3-5 minutes right in front of my house.I installed 8 cameras covering every angle possible, 2 PTZ (pan-tilt-zoom - like the casino's use) domes that I could controll remotely over the internet to see what is going on if I was not home, and motion detectors, microphones - all of this was OVERT meaning it was blatant that you were on camera if you came nearby - I had to put up a sign because legally I could not record voice without notifying the people (video is OK) due to wiretapping laws that are outdated, so I put my sign on the 60 year old tree in front of my house warning people they were under video and audio surveilance. In 3 months we had the dealers out, the rightful owners back, they had to demolish the house because it was so badly damaged, and then they built a brand new 4500 sq ft home in keeping with the neighborhood.About Q-seeQ-see brings the $12,000 DVR that the casinos use to catch card cheats down to the price a homeowner can afford. I recommend any home first install a MONITORED alarm system and make it BLATANT that one is in place (big bell box outside in a conspicuous place) - this will rid yourself of 90% of the crime because criminals know where to look for these and when they find them, they walk on to your neighbor's house to rob instead. After an alarm comes video evidence of WHO did WHAT and WHEN with PROOF. Q-see gives you this.What do all the numbers mean? What is H.264?When dealing with video (which is inherently analog) and you go to digitize it, you would normally find yourself swamped in data, because video is 30 pictures per second, each 740x480, full color (or b&W at night with IR vision cameras). Imagine a 1.3 megapixel camera taking 30 pictures per second - your memory card would be full in a couple minutes at the most.The broadcast industry faced the same problem when the FCC mandated that they "go digital" recently - there was not enough room on a channel to put raw high definition television. So they did what we do on our PCs when we have a bunch of files - they compressed them. This process is known as coding and decoding and is abbreviated CODEC for those of us who dont like to type alot. MANY codecs exist - divx, h.264, h.263, mjpeg, etc. H.264 however crams the best quality picture into the smallest amount of disk space. It's used by the satellite providers to give you more channels than they could without it. Best of all, it's free. No royalties to pay.You're going to hear alot about frames per second. 1 video channel is 30 frames per second. That's for one camera. If you have 8 cameras, then it 8 times 30 or 240 frames per second that your 8 camera DVR must record (if you want smooth free flowing video like you are accustomed to on TV) - now you don't need free flowing video - you can cut from 30 to 15 frames per second and still get reasonably smooth video. The point is that any DVR has a limit as to how many FPS (Frames per Second) it can record. You get to decide which cameras get the best picture, and which ones only take 2 pictures per second (as an example) if you do not have 240 frames per second.The second number to throw at you is resolution. VGA is 640x480 and is about VHS quality. HD is 1920x1080 and will blow your mind af...
