Digifli screens show image files (aka "ads") like a digital picture frame. Each slide shows for approximately 11 seconds. Each screen is constantly rotating through all the slides assigned to that location.
Impression Count
Impressions are a count of how many times your slide is shown on a screen. For example, if your plan comes with 50,000  impressions, your campaign(s) will show at least 1700 times per day.
The impressions are distributed across all the locations you select. For example, if you select 10 locations, then your campaign will show a minimum of 170 times each day in each of those 10 locations.
10 locations x 170 impressions = 1700 impressions per day
If you reduce it to 5 locations, it will show twice as often (every 1.5 minutes instead of every 3 minutes) and still deliver 1700 impressions per day.
Campaigns Share Impressions
Impressions are equally distributed across your ads.
For example, if you only have one ad running then it will show 1700 times per day. If you have two campaigns running, (eg. two slides) then each slide will show approximately 850 times.
Your plan gives you a guaranteed number of impressions. These impressions are distributed across multiple locations and divided among your ads.
