Lately, we’ve been introducing you to some of the folks who work around here, not only to provide you with a better idea of what we do as a ministry, but also to give you a better idea of who we are personally and the diverse group it takes to keep you safe as you travel the province’s highways.
Today we’re talking with Steve Drew, our Senior Electrical Standards Technologist. We also like to call him “the webcam guy”. He does a lot more than that, but when it comes to webcams, he’s the man. Here’s what he had to say about his work with our webcams.
What is your role with the ministry’s webcams?
My role centers on the installation. Beginning with site selection and ending with supervising the installation where necessary. Site selection can be quite involved as it requires considering input from Regions, Districts, and the general public on things like safety, traffic volumes power availability and the like.
I also procure and manage equipment and services, including cameras, communications equipment, solar-power systems, electrical contractors and BC Hydro work.
I also look after some of the technicalities, such as:
- Designing and implementing a telemetry system (that’s a system that produces an automated transmission of data over long distances) to provide remote monitoring and control of solar-powered systems.
- Integrating temperature data into webcam displays.
- Exploring the possibility of including additional weather information such as wind speed, relative humidity, etc.
- Looking into other ways webcam sites may be used to provide additional functionality such as: Broadcasting road condition through localized low-power radio; Environmental monitoring; Traffic data collection, etc.
My job involves a lot of other things aside from the webcams, but during the last few years, the ministry has implemented an accelerated program where we install at least 30 new sites each year (our current counts is 258 and growing!). From April to October, my time is almost totally dedicated to the webcam program. An average day during this time could involve:
- Investigating possible site locations and conducting site surveys. This often means I’m travelling and consulting with local staff and electrical contractors to see if the site is suitable and what technology would be best to use.
- Managing and coordinating the installation with the electrical contractor or with other ministry staff.
- Supervising a solar webcam installation.
- Obtaining cost estimates and quotes.
What are the different technologies the ministry uses for its webcams?
- Cameras: We use several different models of IP-based cameras, both fixed and Pan-Tilt-Zoom.
- Communications: Could be cellular, land-line, satellite, and integration into the cellular network by passing a signal from a mountaintop repeater to the cellular network.
- Illumination: In remote locations where there is no roadway lighting, infra-red illuminators are used to provide light for the camera image. The light is invisible to the human eye so motorists are not surprised by a light suddenly turning on.
- Custom Telemetry Systems: This was developed in-house to provide telemetry data, alarm, and control to solar powered systems.
Who maintains the webcams?
Almost all webcam maintenance is done by the electrical contractors. These folks are brought in to maintain the many complex electrical systems in place that support our technological growth. Technical support is provided by ministry Electrical Engineering Center staff, myself, and the Radio & Electronics group at selected sites.
What do you find most challenging/rewarding
The most challenging has been getting solar powered sites using satellite communication to perform reliably in high-snowfall areas of the province. Each year improvements are made, and I anticipate excellent reliability when final updates are completed this year. Overcoming these difficulties, along with the success of solar powered sites in operation at remote northern regions of the province, I find the most rewarding. Examples of such sites include the Granisle camera on Highway 118, Bowron River on Highway16, but mostly the camera at the BC-Yukon border on Highway 37.
