System Suggestions

[FredB 0]

Putting toghether a 6 camera system for a customer. He wants to be able to read the licence plates on the cars, so really high res. Parking lot with 2 entrances. 50 ' accross. Decent lighting at night. Wants remote viewing but probably wont work if you are recording in 740 X 480. Budget for equipment $2000 - 2500. 4 cameras outside. Those are the key ones.

 

Questions: What compression looks really best??? My experience would tell me Wavelet or MPEG-2.

 

Thinking about:

Tatung 17" with 700 Li

Some sanoy D/N

Maybe a Nuvico or Hunt DVR

 

It seems like you get a better b/w image with a good bullet camera verses a box camera. Box cameras usally looks way to grainy. Why is that.

 

Any suggestions

Depends on the Box Camera ... Exview no matter if it is box or bullet will go grainy in low light. But you can get away with a BW Bullet as the camera doesnt have to do much at all ... and no housing needed so the price is much lower. Just Stay away from the exview ones, look at maybe a Dome instead in High Res, like the WizKid WZ30. Im getting one of them to test for a night club here, and they are not expensive.

 

Samsung Techwin has VERY good pricing on an Exview Day Night. PM me or Herming, as hermin has actually used it.

 

To get licence plates, only if you zoom the camera in on the plate area and turn on BLC, or use a wide dynamic camera, they arent cheap though. Pano has a Wide Dynamic Day Night, or Samsung Techwin also, good prices. Then slow down shutter speed some.

 

All my Kalatel DVRs in the field are in High Res recording, and I can view them no matter what. But way over the budget!

 

Id definately use a 14 or 15" Color CCTV Tube Monitor though, if using a high res cam and need to see licence plates, faces, etc. LCDs are just too pixelised with BNC.

 

Sounds like you have a task at hand, picking cameras that will work properly, in that clients budget range.

H.264 is still best codec local and remote. Look at the ITU/ISO tests. It is clearly better.

[rory 0]

well anything Mpeg 4 ... though wavelet is still great remote quality, it requires a faster connnection as it is larger files ...

 

Mpeg4 is the best I have seen so far ...the Mpeg4 H.264 demo didnt impress me as much as they claim it is so great, didnt look any different, except for speed and maybe file size. For small size then yes it is the one. Course H.264 is the latest Mpeg 4 anyway .. right?

 

Ofcourse on a budget all these compressions fly out the window .. looking at Mjpeg at that budget..

I've been playing around with MPEG-4, WMV, and MJPEG in our beta and you can get all of them to equal quaility...if you're willing to trade space for quality. But from what I've observed it's going to be all about the camera.

What about 720 X 480 verses 640 X 480. Anyone actually see a difference??

 

Thinking about a Hunt DVR. Wavelet, 720 X 480, Quadplex, great remote viewing and remote. Has anyone tried them?? How is the recording quality?? They also have an 8 channel version with the same specs.

 

I am also doing a parking garage with 25 something cameras and I am really thinking about using 2 of theese, but like to get some opions first. No remote viewing, so recording quality is the main thing.

 

Opinons please

[rory 0]

yes, there is a difference ....

The best thing for you will probably be this:

Hunt DVR

but then the everfocus claims 720x480 .....but i doubt it, as it has a crap local image..

[FredB 0]

The I-view looks kind of interesting. The thing is that the system is mainly going to be used to watch people live, and i feel you get alot better live view on a standalone since here is no A/D D/A conversion taken place. However the system needs to have great recording quality to. Will only be recording by motion/events, so HD space is not really an issue.

 

I like the VPON for the "PC based " DVR's. easer to explain to the customer how to work it.

 

Hunt opinions please

I have to say that if you use a VCR with super VHS, that looks better then 90% of the DVR's out there. Probably tried 20 different DVR's and not really impressed by any of them.

kalatel is the best quality yet, but.... for a low end dvr, the powertellecom 4 ch from korea, is close..120pps too

here is my review on the PDVR-R4000

The 3200ASE is actually a Embedded XP system, and with 960fps, you get realtime viewing, and 240fps recording with no hesitation. In all honestly, when it comes to recording and Viewing speed and quality, a stand alone does have a chance against a PC based DVR. Expecially when it comes down to features.

 

Take a look at the Digi-1600XP, new unit from Iview, have sold several already to Casino's and banks, I even had a client with 4 Check Cashing places for over for them, because he liked the fact that the unit could record reatime in ALL channels, and since it is a triplex unit, you have no problems doing recording, viewing and playback at the same time. The system uses both wavelet and MPEG4, you can choose which one to use.

 

The units include a DVD-RW backup, and can be customized anywhere from 320G, up to 2 Terabytes!! The casino's ordered them with the 2 terabytes, and get around 45-50 days recording realtime. But then again, when you are talking pricing, it depends on the size of the HD, but they start retail at around $6000.00.

Hermin, with the Digi-1600Xp how many days recording would you get say on average using Mpeg4, 320GB and round the clock recording. Only thing i like with geovision is they use their own compression method, for one of my clients i gave him a gv800 for a bank, 380GB (400gbSATA before partition) and he was getting nearly 30 days recording no problem with it.

[qman 0]

Well, if you see, the GEO is a 120fps card, while the DIGI 1600XP is a full realtime, 480/480 system, so you are going to habe a much lower recording time like this, probably about 2-4 days, but this is set at the highest level, which is hardware MPEG4 compression at 8 megs. Now, we set the system, like a geo 800 setup, let's say, 16 channels, then we are talking about 7.5fps on each card, which translated to: 24 days recording. You can choose different resolutions and codec setting per each camera, so let's say that you want the teller and lobby cameras to record at a full 30fps, but the office and back of the bank you can set at 10fps. There is many options that you can choose with the system to make everything work the way you want it, but like any DVR, it's up to how you set the unit to operate that will ultimately tell how much recording time you are actually going to get. This is why the DIGI-1600XP goes out with 600Gigs of Hard Drive space minimum, plus the other thing is that there is only a realtime Viewing card available if you want to make a custom system, the highest 16 channel card that is currently available is the 120fps CP-1416ase XP.

 

Although I got a tip from taiwan that a 480fps card is on final debugging and beta testing, and that if everything goes well, it will be available at around the end on April, beginning of May.

 

But there is also one thing to consider to all of those GEO fans out there.

 

Look in this forum, and count how many users are having problems with a GEO based DVR, compared to let's say, not even ONE I-view complaint.

 

Granted that GEO has a much larger customer base than anyone else out there, but considering that over 50 thousand people visit this site regularly, and many unknown DVR card question have been posted, that's got to say something for I-view products.

 

By the way, the above estimate in recording time is for both NTSC, and PAL formats

and let's not add my favorite Video Insight card to the "no problem" list. I am very happy with it.
