Savannah Guthrie revealed in a desperate new plea for help that her family’s $1 million reward for any information that leads to the return of her mother, Nancy Guthrie, will be paid in cash, and the tipster can remain anonymous.

The “Today” show star shared a clip of the NBC program on Friday that explained how anyone with key information about the 84-year-old grandma’s disappearance can submit a tip and collect the reward without revealing their identity.

If authorities are able to track down Nancy Guthrie based on the tip, the tipster can meet with the family at an agreed-upon “neutral location,” such as a post office, and claim the seven-figure prize.

An ID is not required.

The Pima County Sheriff’s Department confirmed it is probing new surveillance video from a neighbor's home that showed vehicles driving by around the time Nancy Guthrie was kidnapped nearly a month ago.

The Ring camera footage, obtained by Fox News, shows a car passing a residence 2.5 miles from Guthrie’s Tucson home around 2:30 a.m. Feb. 1 — about the time police believe the 84-year-old grandmother was abducted.

The FBI is also aware of the video, ABC News reported, although it's unclear whether it will be of any help to the ongoing investigation into the missing mother of “Today” show star Savannah Guthrie.

Investigators made their final sweep of Nancy Guthrie’s home on Wednesday, and are expected to allow the family to return to the property.

Authorities have yet to identify any suspects in the baffling case.

Terrified Arizona residents are rushing to build panic rooms after the kidnapping of Nancy Guthrie — who has still not been found nearly a month after she was snatched from her Tucson home.

Kevin Hand, who specializes in break-in-resistant "safe rooms" at Sportsman Steel Safes in the Grand Canyon State, told the Daily Mail his business has been flooded with calls of late to quickly install thick steel doors and secret hiding rooms in people’s homes.

“There has been a huge spike in calls and business since the Guthrie case," Hand told the paper, noting that many people are scared they could be ripped from their beds, never to be seen again.

Sportsman Steel Safes has built heavy-duty doors and safe rooms for wealthy clients in Texas and California for decades — but now middle-class families in Arizona have emerged as his newest customers, with consultations already booked for weeks, he said.

The abduction of Guthrie, the 84-year-old mother of “Today” show star Savannah Guthrie, has “people thinking, ‘What would we do if someone broke in tonight?’” Hand said.

“People don't want this to happen to them or their families, and they're realizing maybe it can,” he added.

The FBI reported more than 1,500 tips have come in since Savannah Guthrie announced the reward to find her missing mother, Nancy, was increased to $1 million.

Earlier this week, Savannah made her public plea asking for help to find her mom, who went missing on Jan. 31. She was reported missing on Feb. 1 after she didn't show up to a church service.

“She may be lost, she may already be gone … if this is what is to be, then we will accept it,” she said. “But we need to know where she is. We need her to come home.”

A man was arrested for a DUI outside Nancy Guthrie’s Arizona home after allegedly driving by “50 to 100 times” while looking at a photo of the missing grandmother on his phone. This bizarre incident occurred as the FBI scaled back its investigation into the disappearance of Guthrie, who was reported missing on Feb. 1.

The FBI is pulling back much of its Nancy Guthrie team from Tucson to the larger office in Phoenix, and the local sheriff is working to hand Nancy’s house back to her family for good — suggesting the investigation is entering a new phase.

While some agents will remain in Tucson, where the mother of “Today” show host Savannah Guthrie, 54, was abducted on Feb. 1, many investigators are returning to Phoenix to work on the case from there, sources with knowledge of the investigation told ABC News.

It’s been more than three and a half weeks since after the 84-year-old went missing, and there are still no suspects.

New surveillance video from one of Nancy Guthrie’s neighbors captured several cars driving nearby her Tucson home the night authorities believe she was kidnapped.

The footage, obtained by Fox News Digital, was recorded on a street-facing Ring camera at a home in the Catalina Foothills neighborhood roughly seven minutes away from Guthrie’s one-acre property.

The time stamps in the minute-long video shows clips recorded a dozen cars driving by between 12:30 a.m. and 6 a.m. MST on Feb. 1 – the day Guthrie was reported missing. Investigators believe she was abducted between those hours.

During that window, 12 cars passed in front of the home. It’s not clear if any vehicle drove past the house more than once that night.

The FBI is relocating its Nancy Guthrie command post from Tucson to Phoenix, where it has its largest office in Arizona, more than three and a half weeks after the 84-year-old’s abduction.

While some agents will remain in Tucson, where the mother of “Today” show co-host Savannah Guthrie, 54, went missing early Feb. 1, many operatives are returning to Phoenix to work on the case from there, sources with knowledge of the investigation told ABC News.

The person responsible for abducting Nancy Guthrie may have left behind a bigger digital footprint than first thought, even if they attempted to erase or conceal evidence.

"The loudest evidence can be the lack of evidence," Heather Barnhart, a forensic expert who helped solve the Idaho student murders, told Fox News Digital.

"[Killer Bryan] Kohberger literally created bookends around the crime by turning off his device," Barnhart said. "So in addition to all the clearing and other things that he prepped for to erase his digital footprint, the fact that right before the murder, his phone was turned off, and then within like 40 minutes or so after it was turned back on, kind of gave us that tunnel to look down here."

Small clues, like a device being off, movement or tower pings can give investigators clues.

"If the person prepped, they wouldn't ping that tower, but if they went ahead of time and scoped it out or planned, they would have," Barnhart said. "And then you can also look for entry and exit. And then proximity pings, because eventually you're going to turn your phone back on."

Even if the perpetrator didn't connect to WiFi, digital touches could provide evidence in the event a device is found.

"With Bryan Kohberger, he disabled cellular, disabled Wi-Fi and turned off his phone," Barnhart said. "That is extreme measures to not have a digital footprint. So he really took all the steps but still made a mistake … We hope in Nancy Guthrie, that whoever has her made a mistake and that we can uncover that footprint."

The development signals that the investigation into the 84-year-old’s abduction is at a standstill as she’s now been missing for 25 days and authorities have yet to identify any suspects in the baffling case.

The feds arrived at Guthrie’s Tucson house on Wednesday morning, spending more than two hours at the million-dollar property.

A parking ban is set to go into effect Thursday for several streets in the area surrounding Nancy Guthrie's Tucson, Arizona, home, the Pima County Sheriff's Department announced Wednesday afternoon.

The no parking zone in the missing 84-year-old's neighborhood is meant to "protect public safety and relieve area residents from chaotic conditions caused by a large media and social media streamer presence in the area," a notice on the county's website says.

Earlier Wednesday, the FBI spent several hours in and out of Guthrie's million-dollar house at Catalina Foothills Estates. In a sign that the investigation into her disappearance is at a standstill, feds were there to do one last sweep for evidence before deciding whether family can return to the property, sources told The Post.
