D1 vs. CIF?

[mistabob22 0]

I already bought one of those complete systems before reading here that they are not the best. I have a q-see model QT2124 that has 24 channels (not that I plan on using that many cameras but it is what came in the package deal). I realized that it only records in CIF. The 13 cameras it came with (1 PTZ) are 600 TVL. Should I be concerned that the image quality will not be good enough in CIF (I haven't hooked it up yet)? I've seen some DVRs that do D1 but at 7.5 fps. Does the reduced framerate on D1 make the image look choppy? Should I make an attempt to exchange it? I already spent $1000 on this system. Am I stuck with paying much more for a better system? Thanks for any help.

You're definitely not getting the full quality the cameras are capable of.

I'd send it back and get something in an Dahua, personally.

That depends. You're paying extra for a 24-channel machine, for starters, and you know you won't use that many channels. You're paying extra for a PTZ that may or may not be of any real use to you besides "toy" factor. You may have spent money on cameras that won't be sufficient for the various places you plan to put them. You're better off to send the whole lot back and then pick-and-choose the DVR and cameras that will suit your particular needs. It may end up costing a little more... it may actually end up costing less. But look at it this way: what's the REAL cost of a system that doesn't do what you need?

Very valid points. I really couldn't see much of a difference between the 7.5 and 30. Is that the same for all cameras/DVRs or just the Samsung. I have very limited knowledge on the subject but I would have thought that there would be a significant difference between the two. And any ideas on where to get good cameras for a good price if I were to build my own or do you also suggest Dahua for cameras as well? Thanks again.

CIF is to save hard drive space.

D1 is maximum resolution for analog DVRs.

 

Most DVRs show a D1 resolution but actually compress recordings to CIF making D1 Useless. You need a D1 recording @ 30 FPS for full benefits.

I agree too. How many cameras do you really need, first off?

What DVR do YOU offer which can record in TRUE D1 resolution ?

Thanks guys. I've already returned it. I'm eyeing another system that claims to be full D1 recording at 30 fps. From the webpage: (Full D1 Recording Resolution: Broadcast-quality D1 704x480 pixel resolution, 480 FPS Total (30FPS per camera x 16 cameras). This about what I need? I probably won't use any more than 10 cameras at some point down the road. Thanks again for all the help.

hi 704x480 is not D1 ........... also make sure your not just looking at display resolution. which is not its true recording rate

HDSecurityStore's comment is kind of scary to me. Sure, D1 (or close: 704x480 4CIF) is far superior to CIF quality. Recording at 30fps is basically a useless over-working of your DVR's HD unless you -really- need it (think moving cars, casino hands).

 

I set my home channels for 7FPS D1 (really 4CIF), and set the driveway to 10FPS. If you don't know what to do, set it for 10-15, just not 30 - thats crazy.

I read something on this forum a long time ago that I completely agree with: "you're recording events, not making a movie" (who originally said that here?) and I repeat it to my clients all the time. For me, 6fps-8fps seems to be a sweet spot. I don't go higher than that, but sometimes I'll set a camera or two on 3fps depending on the environment and what's being captured, such as an area where the client wants coverage, but is not critical.

Casino hands move 30fps?

You got that one about right except here in UK police recommend 12fps in high risk areas. The reason is that there are more opportunities to capture a still of a subject's face. 3-6 fps in a workshop where staff are monitored mainly so that help can be available in the case of an accident etc.Small Motor Garage workshops etc.

thats a shame

Nice thread, I joined the forum after reading it.

 

Got a very very basic CIF "brand" "model" K404AV generic dvr running. Lots of issues with trying to get motion detection working somewhere in between all or nothing. lol. I'm interested in quality cameras in some locations and ok with basic stuff in others. Interested in leaning and sharing what it takes to get good results.

 

When my beat up outdoor chop saw worth about $30 was taking a month ago on just before lunch on a Monday during the day I decided I had enough. I suspect a transient that lives at a neighbors.
