Who makes one? I notice with my Extreme Reg L1, during the day, it makes some excellent pictures I cant get with my Samsung SDC-415 cam's. I like the low lux settings on the Samsungs, but wondered about some higher res camera's.
-
I'm just looking for a higher res picture than the day night cam I have now. And that would perform as a day/night camera. I have enough light in the area to not require IR assistance. Bottom line, I'm totally happy with the Samsung SDC-415, I would just like a more detailed picture, or at least see what the price point is, and then determine how much its worth to me...
-
What about the extreme fmx800? I guess I should mention I'd still like to have color...
-
Is there a hi res camera that gives me the same resolution os the reg camera? (also with low light capability as the sdc-415). I dont need infra red, as I have low level light for the area, so the BW sens up on the Samsung camera works excellent. Its a good camera, I'd just like better resolution.
-
I tried the 80ft route and got almost 100% capture. I got a different lense, set at 20 ft ,because it has a slightly wide FOV. Capture rate 99%. Only failures in capture are due to old or dirty plates, as the Reg series are highly dependant on the IR reflectively of plates for night time capture.. Also some people use the plastic plate covers, which also deflect IR.

I wouldnt reccomend it. I found many-many bugs with it. Frame by frame playback still isnt useable, and motion detection at the dvr level is useless unless your coverage area is very small. Saving to DVD takes hours if any length of time is needed. Overall, for their "premium" DVR, I'm not impressed at all. Going from the search screen to exit the GUItakes 7 button presses. While they fixed mostof the bugs I've found, the frame playback bug makes it annoying and almost useless.

I noticed some posts pointing out a difference on these, but not how to identify which is which.(other than the 520 is techwin, and the 2391 is GVI) My installer initially suggested the SDC313, I looked at the SCC-B2305, and apparently the Samsung SDN-520 is well viewed here. I need a really good day night camera, switching to BW for nightime is fine. help?

I just got around today, to trying to copy some images onto the built in DVD recorder. I've got the stuff on my windows XP machine to read a UDF formated dvd, so I'm good there, but all the files on the disk are files, and there's nothing on the web about this extension (except about StarOffice) and nothing I can find to play them. any thoughts?
-
they all will do that. My $1k everfocus did that, and my $4k Samsung exactly the same. The motion detection is based upon the movement of a large object within the camera's FOV. So a bug flying close to the camera appears as a large moving object.
-
First we tried the neverfocus (POS!), and even the highest end Samsung (Techwin) DVR and both suffer from poor motion detection.It plain doesnt work until the object is darned near in front of the camera. It appears most of it has to do with object size versus field of view. On cameras with a narrow field of view, motion detection of larger objects isnt bad. On cameras covering a wide area, motion detection was almost useless. We would using external IR motion sensors to cover motion detection farther away from the cameras (appx 100ft). These two camera's with remote IR motion, are covering very wide areas of my residence. Is it just a limitation of the software? Its just odd that both units suffered almost the same lack of detection. The samsung just barely better and at 4x the price. Am I just expecting too much?
-
cars are traveling at 15-20mph. I'm running at (from what I can tell) 30ips. Damned Samsung only gives numbers from 1-15 for frame rate, and I still cant get them to tell me what they equate to yet.
-
I'm running sensitivity at the max. Cars are about 80-100 ft from the camera,traveling horizontal to the camera view. But yes, the motion detection is highly dependant on object size, which is why nothing is picked up unless they are right on top of the camera (within 20 ft). Both the everfocus and samsung exhibited the same lack of detection. Its just frustrating to have to use external motion detection on a 4k$ dvr. Even the other camera, with at 100ft of about the 100ft, cant pick up a car coming directly at it, until the car is within about 30ft.

Camera, Samsung SDC415 w/tamaron lense, dont know the lense size. DVR is the samsung SVR-1650. Trying to catch cars going by. FOV of the camera at 100ft is about 300ft maybe, or just under. I have a camera perpendicular to my long driveway (600ft), with this one camera covering maybe 250ft of of it. Need motion sense to catch cars going by (so horizontal movement). Its not a problem of too much movement, its not catching the cars going by at all without the external IR motion sense.

I have an STI 7100k enclosure with a samsung SDC415 camera in it. I had a yellow jacket get inside the enclosure trying to make a nest, and now there's a small spot on the lense I need to remove. (and yes, its on the lense, not the enclosure viewport). How do I remove the camera from the enclosure to clean it? Also any tips on proper lense cleaning would be appreciated.
-
I'm using not only the motion detection from the DVR, but external IR motion detection. The motion detection on the DVR was so poor on the wide angle coverage cameras, I needed to add external sensors (IR motion) in order to have any real motion detected coverage. Without the IR, someone had to be practically on top of the camera. (within 20ft) before motion detection occurred.

Any tips on how to properly clean the lense? I believe the lense is a tamaron

Of the Reg-L1 camera models, the max distance is 75 feet from camera to target point.
-
As noted above, you need the distances from camera to target point. The different LPR camera models, the further you get away, the narrower the FOV is. So you want the camera and target point to be as close as possible. This is because the FOV is much wider with the nearby camera. For example, I had a Reg-L1 camera with the 75mm setup, and at 66 ft, it had a FOV of not quite 6 feet. Now I was supposed to get the 16mm, and according to ExtremeCCTV a FOV of about 12 feet. I 'll know the answer this weekend, when we install the correct camera. Note, Extremecctv had an online calculator that will as you for distance from camera to target, distance from camera to centerline, and height of camera. These will help you pick the right model for your application. As an example, cam-target of 15 ft, lane center of 12 ft, and height of 10ft , puts me in the 16mm version of the L1.

I guess when you get one of the the first machines around you gotta expect bugs. While its a nice machine, it does have some serious bugs. The worst bug, is that you can cant rewind/ff through all events on only one camera. Only if those events for that camera are in the event list, in order. Any other camera events in between those, the unit appears to hang, screen goes blank when you rewind to the beginning, or ff to the end. Even the everfocus allowed that. While in event list, if you have an event occur while you are viewing or in the event list, occassionaly the unit hangs, or even bumps you back to live camera. And the UI has some serious usability issues, as if you go into the search screen, to get back to camera live takes about 7 keystrokes to get back to live camera. And dont even mention the save/no save option, and the double check dialog that pops up on save. (You have to get to exit, scroll to save or no save, if you select save, another dialog pops up to make sure (yes/no)). Yucky. On the otherhand, picture quality is excellent, video is smooth, and it is cool that I can put a KVM switch between my PC and the DVR,and switch the mouse/keyboard/LCD monitor, between them. (Although I havent yet, its doable). If I'm lucky, there will be a firmware update to fix these bugs...

What system for this application????
jeffpa replied to Wayne02's topic in General Digital Discussion
Because you'll need to sell some to get the system you are asking for. To get License plate recognition, that camera alone is 2400$. You can get so-so recognition from the Panasonic and Bosch cameras. Both are mentioned in the forums if you search. Cost around 600$ each. But if you want 100% LPR, thats the cost of that alone. Just to give you an idea, I used Samsung SDC-415 cameras (day/night) at a cost of 270$ each from my installer (and yes, I could order myself cheaper, but warranty and dealer handles issues was important to me for a first system). My DVR cost close to 4k (Samsung SVR-1650). Install time alone will long exhaust your 1k budget, depending on the installation. You can go cheap if you want, but then thats what you get, a cheap system. -
Linux is the battle cry of the anti microsoft crowd, windows is the still the predominant OS in businesses, and those same businesses dont need another IT department to cover Linux admin. And yes, the window UI's under Linux are not nearly as refined as Microsoft's UI. Programmers go where the cash is, and it isnt Linux.

It is far more effective if sent from a lawyers office. For a real punch, have the letter served to him. I had a neighbors kid on a dirt bike tearing up my field. Letters, cops, etc, none worked. A letter from my lawyer served to them took care of it.

I just installed the Samsung SDC-415's and luv'm. On super low lux mode, with some amount of existing light, they really perform great. Nuvico, GE DVRMCe, Dedictated Micro's, icrealtime, samsung (techwin) are all good dvr's.
