What about XGA (Extended Graphics Array) isn't that an analog video signal at 1024x768?

No higher resolution cameras or recorders? Any other opinions?

Welcome!

Well... So what happens when the DVR is behind a outward swinging steel door in a locked basement which has a remote offsite backup?

What on Earth does that mean?

Hmmm... 1/4'' what CCD CMOS? May be just a crap camera.

What do you think of the quality difference? This is some man putting flyers on the property Comparison: 480tvl Sony Super HAD (3.6mm camera mounted approximately 5 feet above garage door ) vs. 700tvl Sony Effio (Vari-focal camera mounted under garage door frame)

Welcome

What do you think of this story? http://www.silive.com/news/index.ssf/2008/08/new_heights_for_invasion_of_pr.html

You have to show us some behind the scenes work... This little casino wont let you? Just joking by the way. Correctamundo! No IP infrastructure, no budget (would cost millions) and nowhere to put the necessary switching equipment. Wouldn't go full IP at this point anyway - PTZ latency is a deal killer, for one; unproven long-term reliability, for two; consistent 30fps frame rate, for three and low light performance for four. Closely watching SLOC.

It was joke. We know analog sometimes is better in low light as rory emphasize. This is why rory always emphasize price does not mean better performance.

Rory; Would you make the casino switch back to analog when you get the job? Just kidding by the way.

Makes sense. Can you show us some example pictures? Think about it again. Let's say you have one camera at each end of a north/south aisle. A customer enters from the north. The camera at the south end will see their face. If another customer enters the aisle from south. The camera at the north end will see their face. Maybe if they entered, turned around and immediately exited the aisle, it would be difficult to ID them but if they just walk less than 1/4 of the way down the aisle, their face will be ID-able. By the way, the cameras don't have to be at exactly the end; they can be maybe 1/8 to 1/10 of the way or so from the end. The closer they are to the center of the aisle, the less zoom they will need. However, the less the zoom, the longer the aisle will appear to be (people at the opposite end will appear smaller) and the less likelihood of ID'ing them. The key to this working well is to adjust the zoom so that the aisle width fills the horizontal frame at the halfway mark.

True But when people enter isle their head is usually up and looking forward, as a person exits the face usually looks down and to the side. No?

Its not very neighborly and surely wont make the relationship better.

This is what I though: Cameras in middle looking towards fronts (entrance) of isles will capture faces of persons entering. Camera in front and back will capture back of person.

Cameras are also often criss-crossed at big chain supermarkets in the center of each isle. Its much better for the cameras to be somewhere in the middle of the isle then in the end. Interesting. What does the "zoom effect" do to the rest of the image? Is the rest of the image focused? Like the closer range sections. If I have to I will put two cameras in but I was hoping to only use one. It works in our casino. You are actually focusing on the more distant objects and using the camera at one end to see the opposite end. I assume that light levels would come into play, though. Our hallways have 4x48" flourescent fixtures spaced about every 12 feet or so. With the irises closed down so much, focus becomes far less critical. I call it the "vertigo effect", as in the Alfred Hitch**** movie.

Agreed! Mini bullet IP Cameras exist? Show us please!

Let the person choose. Don't only offer what you would get.

Why?

So is it not good?

Whats this then? http://www.ebay.com/itm/Arecont-AV-2100M-2MP-CAMERA-/300616836031

rory why cant i send you a PM?

Maybe on eBay: Never tried it though. http://www.ebay.com/itm/WIFI-IR-IP-Camera-CMOS-3MP-Waterproof-LED-Night-Vision-/320704167392 you might just get a 1.3mp for that sort of money.
