Pat,
I'm not a user of the system, but do have a little experience with digital imaging in the latent print field.
I assume that your agency is looking at this unit:
http://www.mideosystems.com/system_latent.asp
The first thing that I can comment on is that they need to turn the latents right side up in their demonstration!
Here is my opinion on these 'digital imaging solutions in a box'. Most are overpriced for what you get. Most of the features of these systems are available with common image processing applications like photoshop. Most offer subpar image capture solutions for the price. The benefit to these types of systems is the image storage and tracking capability (and that benefit is mostly to an agency with several examiners that doesn't have someone knowledgeable in computer networking to manage the database, or for a large agency that needs to distribute images to a wide variety of people outside of the latent print lab). Dont get me wrong, these systems have their place.
Here are some of the features listed from the MIDEO website and how they can be performed using Photoshop, plugins, and/or other windows applications:
"All acquired images are stored in a secure database that is password protected" - This can be accomplished by storing your evidentiary images on a server with Windows Server 2003.
"All images include an audit trail in order to maintain the integrity of the original" - A simple hash generation of original images by a number of free programs can perform the same task. If there is a question about the image integrity, hash the original again and compare the two.
"Latent print images can easily be printed at 1:1 and submitted to AFIS or side-by-side comparison" - Any digital image with a scale can be easily printed 1:1 with photoshop and most other image processing applications. I am unsure if they intend to print the images and then enter the printed image into AFIS. If so you are essentially making a copy of a copy of a copy. Ideally you would be able to import the processed digital image directly into AFIS, but it is unclear if this is possible with this system.
"Our latent print imaging system features a high resolution cooled 5 mega pixel camera..." - Thats nice, but you can get a 12 mega pixel camera body for around $4,500 or less (Nikon D2X). I regularly get image resolutions exceeding 2000 ppi with this camera. On top of that after talking to a member of SWGIT, the minimum recommended standards for comparative analysis image capture will be changing in the next revision (and I'll give you a hint that it's not getting lower). So a 5 megapixel camera may fall below SWGIT recommendations.
"The camera provides a full screen live display on a computer monitor" - I will admit that this is pretty cool and you can't do it with a Nikon D2X. But there are digital cameras on the market that have greater resolution than 5 mega pixels which offer a live preview of the photo.
Again, I am not trying to be overly critical of these systems. They have their place, but for the features that they offer they are generally grossly overpriced. For a lot less money you can get a very robust digital imaging system with better equipment.
You can buy a good digital imaging PC now for around $3,000 (Dell XPS 710's are right at $1500 or so). Adobe Photoshop CS3 extended is $1,000 from adobe, and likely less from a 3rd party vendor. 3rd party plugins for CS3 so that you can perform FFT and other processes, $1,500 (Clear ID from Ocean Systems and Fovea from Reindeer Graphics). Digital Camera is $4,500 if you go with the top of the line, and you can get really good quality cameras for half that. 24" Dell LCD monitors are going for around $500. SWGIT now recommends that evidentiary images be archived to RAID servers. You could probably set yourself up with a 10 terabyte server setup for $10-13K. An Epson 2400 for high quality prints will run you around $750, if you want to get crazy and go with a large format printer to print charts (up to 17" wide) you can get a Epson 4800 for around $2K.
Note all prices are estimates, I'm sure that they will double all prices listed above for government contracts...
So taking even estimating high, you can get yourself a really kick rear digital setup, that will do everything the Mideo system can and more for around $25K. I have no idea what they are charging for their system, so I dont know how that stacks up.
I dont have a dog in the hunt and dont sell any products listed above, but if I was starting from the ground up I wouldn't buy one of these canned systems. Feel free to PM me or email me if you have any other questions.
