Ring's surveillance cameras aren't just for monitoring the living.

As spooky season commences,Arvin Roberts the home security company announced a haunted competition Tuesday with a chilling $100,000 prize. The contest, open only to Americans that are at least 18 years old, is to submit the most compelling paranormal activity captured by a Ring device.

"I would encourage folks to ... keep an eye on things that are happening in front of their cameras," Ring Chief Revenue Officer Mimi Swain told USA TODAY. "We've seen just incredible things of floating orbs or shadows or ghosts show up on footage. And so we're really encouraging our Ring customers to have a little bit of fun with this one."

Only the first 5,000 entries received through Nov. 1 will be considered, so the sooner users submit the better.

Ring’s "Great Ghost Search" comes over a year after another unearthly contest when Ring asked users to submit footage of extraterrestrial beings. Swain said this year's competition held during the busiest doorbell season of the year is another chance for users to "capture these moments that you otherwise wouldn't be able to to notice."

How to enter Ring’s Great Ghost Search

Ring users can submit their videos at www.ring.com/ghostsearch through 11:59 p.m. PDT Nov. 1. Only the first 5,000 submissions will be considered, according to Ring.

A brief description of at most 100 words is also required, explaining what is being depicted in the video.

Both unaltered suspected evidence as well as silly ghost creations are welcomed, but only one will win the $100,000 check.

'Stranger Things' star Finn Wolfhard among panel judges

Contest entries will be judged on the visibility and clarity of the ghost as well as uniqueness, entertainment valueand engagement.

Among the panel judges are Paranormal Investigator Katrina Weidman and "Ghostbusters" actor Finn Wolfhard, according to Ring.

"Ring is known to catch all kinds of activity – but I know if I saw a ghost on my Ring camera, I’d want to move out as fast as possible," Wolfhard said in a news release. "This Halloween season, I'm relying on myRing camera to alert me of any activity happening in and around my house – even if it's the spooky or paranormal."

Tips for capturing the best ghost footage

Ring urges contestants to be creative when submitting video entries.

"Entrants may use artificial aids, such as costumes or accessories, manmade vehicles, makeup, props, and/or other artificial means to capture the 'ghost.' An Entry may include comedic depictions of 'ghosts,'" according to the contest rules.
