What safeguards does the Ministry of Transportation take to prevent stale images from appearing on the BC HighwayCams site and DriveBC?
A. When images are transmitted to our server from the cams, they are electronically monitored. If an image is not being transmitted, or if the same stale image is being transmitted repeatedly, our monitors detect this and send our technicians an alert. Images that do not update after an hour automatically change to a faded image with the words “Transmission Delayed”. Stoppages like this are often caused by interupted communications, but other factors can also cause an image to appear “stale”. After 24 hours, if the image has not updated, the cam is manually “turned off” on the website and replaced with a message. This is to prevent users from being misinformed by a stale image. To minimize browser caching, which could cause your browser to display an old image when you open the site, the web pages have been set to update automatically every two minutes. That does not necessarily mean a new image will appear every two minutes — just that the page will reload the most recent image avail
