Question: How can I tell which direction the camera is pointed?
Answer: The camera is set in the home position. This is the position used most frequently by the staff in the traffic control center. We have a typical morning scheme and afternoon scheme which automatically sends all cameras to pre-set directions. Generally speaking, these automatic settings keep the cameras pointed so that the heaviest traffic flow is oncoming or heading toward the camera. When there is no incident to monitor, the cameras are usually zoomed out and pointing in peak flow traffic direction. The cameras can be rotated 360 degrees as well as zoomed, panned and tilted.

Question: I was in an accident near one of your cameras. Do you have a video tape of the accident?
Answer: We do not regularly record our camera feeds for archiving. No tapes will be kept.

Question: What hardware/software do I need to view the traffic camera images?
Answer: You need a PC that is networked to a standard telecommunication line, LAN, WAN with an Internet connection and you need Web browser software loaded on your PC (either Internet Explorer 4.x or Netscape 4.x browsers are required). No other software is required because the JAVA applet will be downloaded to your browser or monitoring PC.

Question: How often are the camera images updated?
Answer: Camera images should update automatically every 15 seconds.

Question: Are the cameras able to read vehicle license plates and monitor traffic speeds?
Answer: The cameras are not able to read vehicle license plates and do not have sensors to detect traffic speeds. Cameras are strictly for traffic management use only, not for law enforcement.

Question: What are the benefits of the video cameras?
Answer: Some of the benefits of the video cameras include:

In addition to the benefits listed above, current technology has a potential to provide other monitoring capabilities we will be looking into as we test our first installations.

Question: How do the camera images get from the field to my monitor?
Answer: The cameras are connected by a Category 5 cable to a server located out in our buillding. The server transmits the images from the camera to an web server by using standard Internet Protocol. The end user is then able to view the images by logging on to the Web site.

Question: Your page uses JavaScript, how can I tell if it is enabled?
Answer: JavaScript is required to refresh the images. Most browsers have JavaScript enabled by default. To enable or check your JavaScript settings:
