How bright are the screens? Can you see them in the daytime?
The digital LED screens are as bright as most roadside digital billboards. Brightness levels are often quoted in candelas per square meter or NITs (the terms are interchangeable). An ordinary TV has a brightness level of approximately 350 - 500 cd/m2. The outdoor screens used at your bank's ATM or the fast food drive through measure approximately 1500 cd/m2. The P6 LED displays used by Spark have a brightness level of 6500 cd/m2. Take a good look at the photos and especially the video clips on this web site. You'll notice that almost all of the photos are taken on fully sunny days. This is intentional, to demonstrate the visibility of the Spark LED display systems.
Can I play video, like TV or movies, on the screens.
Yes. If you're looking for an answer about the technical ability of the displays to show video, that answer is also yes. However, LED screens are not like a regular TV and they require special components to show live video. That component is called a video processor, and it's included with all digital video truck bodies products from Spark (optional on vMod systems).
How does one deliver ad content to the screens?
Regular (non moving video) ads are created in JPG format and are stored on a media player, which is a small box connected to the video processor, which in turn is connected to the LED screens. The standard media player has a slot for an SD card and it's easy to add/delete the ad files on your personal computer, however, most Expo and vMod configurations include remote administration, which includes a live 3G/4G Internet connection and software that includes the ability to create custom playlists of ads which can be uploaded live to the truck while it is on the road.
What is location-aware advertising, and why is it important?
We engineered a GPS based advertising solution that allows you to define geo-zones on a map, and when the truck enters any one of the zones, it can automatically switch all of the advertising. This has valuable implications for advertising sales. For example, if there are certain parts of your city where residents speak a different language, it's possible to create alternate language versions of your ads, and when the truck drives into that neighborhood, the ads will instantly change to the other language without any action by the driver. Another example shows how to use the location aware feature to benefit a group of allied businesses. In your city, there may be a dozen different insurance agencies all operating under the same brand, each serving a unique part of the metro area. Since they all contribute a portion of their revenue into a cooperative advertising pool, the pool funds can only be spent on advertising the benefits everyone in the coop group. You could contract with the group for the entire metro area, and as the truck drives around, the appropriate ad for the agent in that part of town, where the truck is currently driving, will be displayed.
