After the uber-heated discussion in our lab last night about how the Toshiba PTZ camera is completely obsolete, loads of indegenous abuses were thrown at me. Hence, the dormant blogger in me booted up to life and here is my first sweet post....
The small cameras that the team saw are similar to this one:
http://www.theimagingsource.com/en_US/products/oem-cameras/usb-ccd-color/dfm21bu04/
DFM 21BU04
Dimensions H: 50.6 mm, W: 50.6 mm, L: 50 mm
Mass 265 g
Supply voltage 4.5 to 5.5 VDC
Current consumption approx 500 mA at 5 VDC
So lets take this as an example and proceed...
Some of its drawbacks are average image quality,no inbuilt autofocus(cause images to be very blurry and the objects in the image are thus difficult to extract from background),no light sensitivity detector (clouds,air densities will change the amount of light entering the camera lens), the camera lens has to be manually changed for different focal lengths testing (focal length depends on the working distance,object height and width and CCD format,moreover there are standard lenses, our requirement is 59.96 mm (WD=250ft Object H=10ft CCD type=1/4"),there is a 60 mm lens available on this site but whether it will be sufficient can only be commented on after testing few lenses within this range.)
If the respective departments think the mechanical and electrical requirements are well under limits then I still wouldn't mind working with this camera. Moreover, a better quality digital camera has already been ordered,hence,if the team again decides to throw some unnecessary heavy custom abuses at me ,there will be no hardware constraints in switching back.
And thus I would like to end this post with a humble and happy note by thanking everyone for their kind and ever-ready support.
Thank You
