'Warm and fuzzy' may not be the first adjectives that come to mind when you think of surveillance footage, but Coca-Cola's new ad hinges on feel-good footage from an unlikely source.

"People tend to associate security cameras with negative events, but we wanted to disprove that assumption by demonstrating the abundance of happy events and actions they capture," said Martin Mercado, the creative director behind the ad.

The video montage opens with cameras looking around like innocuous, even curious creatures as the 1977 hit Give a Little Bit plays in the background.

Several scenes show people stealing kisses, attacking friends with hugs, doing good deeds and putting themselves in harm's way to help strangers.

The ad had the desired effect on many Youtube viewers, many of who said the it made them tear up.

"Faith in humanity: restored," said riverwater252.

"So positive. As always Coca cola knows how to make people smile," said link4smile.

But others took issue with the ad - and its corporate backer.

"Oh Coke... You try to be so clever by making cameras and people being constantly watched seem appealing," said ShanaSkydancer.

"This is a part of subliminal persuasion. Coca cola has nothing to do at all with the video but they want us to create a feeling of love/happiness in our minds and associate it with Coca Cola: their product," said shekharsvilla.

"Aw, Big Brother, I love you too," said YllwMonky456...
