2.4Ghz Mini Wireless Camera

I eventually got one of these cameras via an Ebay seller. But how to you get the thing apart? is it just a case of prising the black ends off? I need to modify the power switch as this won't be accessible when my Robot's finished

@Gunner, just for the hec of it I ran Microsoft's .NET repair tool, which did correct some problems, but nothing that helped with the camera part of it. I totally understand that there will be some lag, but if the camera can only do 5fps using different software packages(EG Blue Iris) and that was in 320x240 mode, if I went to 160x120 mode the camera would get up to 20FPS but the image quality was horrible. I was going over some of the video tutorials and DJ'S camera you could clearly see that it is MUCH quicker than what I have. I don't remember seeing any option in ARC to change the resolution, but I don't know what resolution the software expects, or for that matter the highest frame rate at which it can process the video....

It could be a signal issue I suppose, right now my robot is less than 10 feet from the computer with the ARC software. I do have a couple Wifi routers and I disabled them just to test and the result was the same. About the only other thing I could do is just buy another camera and see how that does, or I guess I could find a small wifi camera and go that route instead...

@charleybot I found a simple viewer that helps me test cameras without any other fancy purposes that might complicate the results... it doesn't actually display real-time FPS, but when choosing resolution it does show approximate levels expected. Try this from Bustatech.com
WebCamViewer

@Gunner, thanks for the link for WebCamViewer, the camera works fine with it, and does not look like it's at 5FPS anymore, it actually looks like at least 10-15FPS. Just trying to figure out what to do if the camera is working correctly, however with ARC on 3 different pc's what else should I be looking for?

Thanks

@charleybot here is a silly question, but when using it on ARC are you aware there are two viewing modes, Processed Video and Realtime Video? The default, Processed, is slower and less sharp (lower resolution) then whatever the native signal from the camera is... this is done on purpose so things like motion, face and colour tracking work faster as they do not need the high resolution we like to see. The Realtime Video option should show you what your camera is actually doing.

Edit: it doesn't matter to ARC which mode you chose (it always used the Processed)... the options are for us for use when adjusting for tracking or just to watch what is going on.

@Gunner, not a silly question at all because at first the other day when I started with ARC, I didn't notice the tabs until I started seeing it put squares around objects I had it set to detect, from there for testing I have been going between the realtime and the processed, the processed I expect to be low quality, but the realtime I am still seeing low frame rates, the picture quality is there, just the fps is really low.

@Charleybot Well so much for simple fixes:P This is a harder one to resolve as things like computer speed, O/S, background processes and, of course, the program being used for viewing can all have an effect on one's perceived refresh rate (since neither program seem to have a FPS display that I can find).

As a simple and somewhat subjective test, I placed an analog clock in front of my wireless camera and watched the second hand move... flipping back and forth between ARC and WebCamViewer (at 640x480 30FPS setting) ... it seemed that the FPS is lower in ARC, but not really enough to degrade functionality confused

Perhaps you are recording at the same time? (not sure if that slows display down - EDIT: it does a little bit for me). I know at first I kept accidentally hitting the Start button myself... probably just because there is a small delay before seeing the picture and hey, the big button does say START and not RECORD:P

@Gunner, I appreciate your help with this, I am going to order another camera next week and see if there is any difference, hopefully there is, if not then I can't think of anything else to try. I did check to make sure that I was not recording at the same time and I wasn't, but now that I have paid attention to that button, I already hit it by accident a few times....

One other thing I am going to try(and that's if I can find the thing) is my Foscam Wifi camera, at least if that works good it's a start...

@Charleybot Glad to have been of some limited assistance:) I can say one thing that just came to me... when driving my Gunnerator bot around using it's POV (and the wireless cam) I have to be careful as the robot easily overdrives my visual awareness... Drive a bit, stop and wait for the cam to catch up, drive a bit more... like a mini Mars Rover:D Perhaps when other controls are being used, ARC focuses more on other processes then smooth video:) Makes sense as video is not likely its primary function... controlling everything else is:D

Take care!
