I would like to use fisheye cameras in a retail store. The area to be covered is 12 metres x 24 metres. I have not yet installed a fisheye so I'm looking for a general answer. Will I be able to "see" the whole area with 2 cameras? What is the maximum distance that is commonly used from the camera to the wall. I have had a look on the youtube videos and demos but none of them give a reference tgo the size of the room they are working with. Thanks Eric

Geovision has stopped TVOut support on their capture cards and are now suggesting the use of Digital Matrix instead. I want to have a TV monitor located about 30 metres away from the DVR in another room. Previously I would have used an RG59 cable with BNCs. How should I do that now? My understanding is that I need a long VGA cable, and set it up as a second monitor on the DVR. Maybe I should use VGA extenders over cat5 cable?? Or is there a better option? Either way the cost is much higher than before? Thanks Eric

Hi Everyone, The response has been really good so far. I also emailed Geovision and their reply is below. So between all of us, it sounds like if I need facial recognition I'll need to install at least 3 cameras, but for general surveillance I might be able to get away with 2. But it depends on the height as well. Obviously if someone else reads this posting they will need to make their own final judgements.

You can still view the objects beyond this area, but you may not be able to see all the details of the object. If you mount the camera higher, the distance between the object to the camera is further, therefore, the objects are going to be even smaller as well as the coverable area. For a 12m x 24m area, we would suggest you to install at least 3 cameras.

Thanks for the reply. That really is the question - what coverage can I expect with the camera since I can't just go arouund drilling holes throughout his building without some sort of idea if I am going to get 12 x 12 metres- I would like to use Geovision cameras but I'm open to other suggestions.
