For a very long time, the greatest hurdle to successful digital signage was the cost of the hardwre, and by hardware I mean the screen technology. Now you can head to your local bricks-and-mortor or online retailer and pickup a screen for a relatively small amount of coin. Sweet.
However, there are some traps to watch out for.
The cheap domestic stuff is designed to operate 6 hours a day, and it's expected failure rate is generally tied into the warranty period - this is called design obsolecence. All first year engineering students learn about this. Is your store open longer than 6 hours per day? Oh, and forget about the warranty - that vaporised as soon as you installed the screen in a commercial environment. Worth the risk? Not sure, add that to the risk matrix and see if it is acceptable.
Domestic screens always include a digital receiver. I have lost count of the number of times that store screens are playing sport, or B&B, or something other than the store promotions. If you have multiple outlets you need to make sure that your staff are not doing you a dis-service by "flicking the channel over to the cricket".
What sits behind the screen? A solid state media player, solid state computer, the spare PC from out the back, is it running Windows, iOS, Android, Lynix? What about the driving software? Is it easy to use? Do you need a degree to change something? Are you allowed to change anything? Is there any thrid party advertising? Is it complementary or is it a competitor?
What looks cheap to setup usually looks like a cheap setup.
If you have decided to take the digital plunge, partner with someone that is going to guide you along the way. Oh, and by the way, your teenage child may be all keen to do the setup
for you, but may not be as committed to the cause as you are.
If you do go it alone, what ever you do, do not have the screen switched off during operating hours. Play something relevent, even if it is a cooking DVD if you are a food outlet. Nothing shouts success more than at blank screen - NOT.
