Security cameras for monitoring employees computer screen

 Hello,

I had just setup a Q-See DVR 8-channel system for a customer's car dealership a couple weeks ago.  He uses the system to monitor what the employees are doing while he is at his home in another state.  

Everything thing looks good to him on the video stream over the internet.  However, the cameras will only let you see a blurred vision of what is on the employee computer screen.  He was wanting to swap out the cameras with ones that would focus more clearly on their screens (employees) however, give a wide enough angle to see a little of their surroundings at the same time.  Without making it too obvious he is watching what they are doing on the computers.

There has been allot of issues with porn, youtube, and facebook.   However, no one admits it was ever them. lol


Is there such a camera that costs under $200?  Would this be a matter of getting cameras with manual focus?

The DVR is a BNC connection.

Thanks for the help in advance!

Mike

I would use a monitoring software vs a camera to see what is going on with the network, good camera's can get pretty expensive but cost more that $200.  I used a software called SONAR or SPECTOR which will basically tell you everything the person is doing (chats, email, websites, keystrokes, programs used, etc).

It is actually really hard to detect the software, even as an tech.

Here are some sites if interested.

That is a very good point and it has been talked about.  However,  he is more into the cameras right now and so that means I have to stay with the original plan.  Using security cameras to do the job. That it shows this person was on this terminal looking at this website.  No gray area open

The camera that i would think might work is the one we use in our network department, we tested it with out drivers license and we can see it clear as day.  We have a Panasonic BB-HCM381A Network camera but as i stated above it costs way more that $200

That is a sweet looking camera!  Looked it up on google and it does have great zoom and features!  However, with a $800 price tag and needing about four of them (One for each location).  That could add up pretty quickly.

The resolution is impossible with wide angle and catching content on a computer monitor.  Even with a megapixel camera (3-4 times the cost of "standard"), you've got only ~1200 pixels width.

Assuming you have even a small 20-foot field of view, that's 1200/20 = 60 pixels per foot = 5 pixels per inch.  So, a 17-inch wide monitor would have 85 pixels, instead of 1024 or 1280 or more.

That also assumes you can see the monitor...which is rarely the case.  Wide-angle shots are typically overhead.  The screen height in frame would be 10-20 pixels tall, if visible around the user's head.
