Who is Worse, the Driver or the Camera Installer?

The person driving this car is certainly no rocket scientist, and has obvious problems navigating her vehicle.  But the real crime is the video camera that captures no clear image of the person’s face or car license plate. YouTube.

    Hi Steve,
    While the camera installer could certainly have produced a clearer image, it is not realistic to presume that anyone could have achieved a clear face image. (Also, let’s be fair and discount quality loose for encoding onto Youtube).
    This is fundamentally an issue of resolution relative to area surveilled.
    Two fundamental alternatives are available:
    – Decrease the field of view
    – Increase the resolution.
    Decreasing the field of view could dramatically increase the cost of the deployment. Maybe their is an economic return for this business to do so but the cost would increase by integer multiples.
    Increasing the resolution demands megapixel cameras. Using SWGIT standards and assuming the field of view is between 50 and 80 feet, this will require somewhere between 2000 and 2500 horizontal pixels to capture a clear image of a person’s face. This would entail a 3 or 5 megapixel camera.
    Best,
    John

    I’ll give you the YouTube encoding point, John.
    OK, so let’s install megapixel cameras…

    I’m using this painfully funny video clip to illustrate something I find to be very common in physical security: namely security systems delivering ineffective results. How many times have any of you seen blurry images from security cameras? A lot, I would guess. Or cameras with less than optimal field of view, focus, or resolution?
    Plenty, I’m sure.
    That’s because – as I’ve discovered – there is onften a disconnected between installer and customer.
    an installer may do a super job installing the camera in the parking lot that the customer requests. But WHY did the customer request it in the first place???
    Understanding what the customer truly wants, and not just what she SAYS she wants is the difference between good security and bad security.
