Mega-Pixel IP Cameras
You've mentioned Mega-Pixel IP Cameras a few times. What are they all about?
Mega-Pixel IP cameras provide all the benefits of IP cameras but, depending upon the number of pixels delivered (1.3, 2.0, 3.0, 5.0 or beyond) they provide multiple times the resolution of standard analog or IP cameras.
It is our opinion that if it were not for two things...
1. Many government specifications (where cost is seldom a high
priority) mandate the use of IP ONLY equipment, and,
2. The advent of Mega-Pixel IP Technology...
there would be very little application for IP ONLY systems.
That said, following are dramatic examples of the image quality that Mega-Pixel IP cameras deliver.

That said, following are dramatic examples of the image quality that Mega-Pixel IP cameras deliver.
CASE STUDY 1
We recorded video with virtually identical fields of view from two cameras. The images (left column) are from a hi-res, 540 horizontal line analog camera recorded at 85,000 pixels per frame. The photos (right column) are from a 2.0 Mega-Pixel IP camera recorded at 2,000,000 pixels per frame.

The IP camera delivered about 24x the analog camera's resolution.
 Hi Res (540 line) Analog at 252x240
84,480 pixels per frame |
 2.0MP IP
2,000,000 pixels per frame |
At first glance one does not really see any significant difference in the two pictures - one may even conclude the analog camera provides better color definition and a more "realistic" picture. The value of resolution becomes apparent when we "zoom in" on each image.

The difference in resolution becomes dramatic when one tries to zoom in on a subject. The left image quickly blurs (becomes pixilated) because there just isn't enough data points to maintain clear, crisp image quality - forget reading the nameplate on the French door label. Conversely, the IP camera on the right shows grain detail on the wood frame and the sign (even some of the smaller letters) are completely legible. In fact, what we could not read in the upper image pair now (after zoom) becomes crystal clear.
CASE STUDY 2
The real benefit of Mega-Pixel IP imagery is realize when a post recording image is zoomed in to determine additional detail that may not have been recognized initially. The photo below was excerpted from video footage recorded at a recent trade show.

The two gentlemen engaged in conver-sation are about 15 feet from the camera.

Did you notice the "Maytag Commercial Laundry" sign in the upper right corner of the picture?  |
Expanding the main photo 2x - 2.5x we cannot read the notes sketched on the pad in the left gentleman's hand but we do get better definition of both subject's clothing, facial tones, etc.
Finally, with the original picture expanded to about 10X we begin to see some degradation of the image quality but not before we get a clear facial image detailing contours, blemishes, hair color etc.
CASE STUDY 3
We copied the picture below from recorded history on one of our convenience store customers' hybrid systems.

It is a bit subtle... but did you notice the field of view this camera provides? The entire retail floor of this C-Store is captured in this single image! Not only that (remember MP-IP cameras provide much greater resolution), consider the detail (below) that was taken from the data in this photo.

 The detail that each of the secondary images provides is exceptional - possibly even nicer than many of the very best
|
analog cameras - before any post-recording zoom!
CASE STUDY 4
Similar to #3 above, we've copied the picture below from recorded history on another of our convenience store customers' hybrid systems.
Again... a bit subtle... notice the relatively wide field of view... much of the retail floor and the entire transaction zone of this store is captured in this single image! Not only that, consider the detail (below) that was taken from the data in this photo.

The "post recorded zoom" on each of these images is approximately 5x. Notice each image is crisp, clear and there is virtually zero pixalation.
Analog cameras - even when recorded at the highest resolution pixelate after about |
2x post-recording zoom. The original image (Case 4 - big picture) was 3.0 Mega-Pixel.
