More mysterious drones were spotted “pacing back and forth” above New Jersey, new video shows — as government officials assured Garden State residents that there’s nothing to fear.

The footage, captured by a New Jersey mom and shared on X, shows blinking lights buzzing over Bergen County on Sunday night.

“They’re just pacing back and forth going very slow,” the mom said in the clip.

“It doesn’t sound like a plane… no, no, it’s too quiet. That’s a drone,” she said, adding that she counted five or six flying machines hovering overhead.

The spate of drone sightings across New Jersey has raised alarms among locals — who in recent weeks have filmed and posted countless videos of the unidentified aircraft to social media — and left local officials scratching their heads.

But even as the sightings continue to confound authorities, Gov. Phil Murphy said residents need not worry — the drones pose “no known threat to the public at this time,” he wrote last week in a social media statement.

“We are actively monitoring the situation and in close coordination with our federal and law enforcement partners on this matter,” he added.

That provided little comfort to the frazzled residents of the Garden State, including Rachel Campos-Duffy, wife of Sean Duffy, President-elect Donald Trump’s next nominee for transportation secretary.

“If you live in Morristown, Mendham, Summit, Bedminster, Far Hills — that whole area, that’s all you’re talking about,” she told Ainsley Earhardt on Fox & Friends on Monday, referencing a cluster of wealthy Morris County suburbs.

“I think what you’re seeing is, first of all, no answers — whatever the governor put out was a non-answer, and it didn’t make me feel any better,” Campos-Duffy said.

“And I don’t feel good — they’re flying low. They’re not up high like an airplane. They’re flying low, you can see them. And they’re large. They’re huge. These are not hobby drones.”

“People are outraged,” she added. “Three weeks, no answers.”

The feds have said they are looking into the mysterious sightings that began on Nov. 18, when cops first responded to calls about them hovering over Morris County.

Since then, drones have appeared in the night over homes, neighborhoods and military installations across the state.

“Unfortunately, we don’t have many answers, and we don’t want to guess or hypothesize about what’s going on,” FBI spokeswoman Amy J. Thoreson told NJ.com on Wednesday.

“We are doing all we can to figure it out.”

Meanwhile, conspiracy theorists are doing their best to fill in the gaps.

Some say criminals are using the drones to case houses for future robberies, while others say they might be the eyes and ears of terrorists lurking in our midst, according to NJ.com.

Still others say the Chinese or other hostile foreign nations are controlling the devices — while some go off the deep end completely and claim aliens have engineered the whole thing.

Although cops haven’t commented on the slew of silliness, Pramod Abichandani, a professor who directs the Advanced Air Mobility Lab at New Jersey Institute of Technology in Newark, told the outlet those explanations are unlikely.

If the drones had a nefarious purpose, he said, they probably wouldn’t be so loud and visible.

“It would be extremely careless on the part of people who are working for foreign powers to just expose themselves like that,” Abichandani said, adding that the machines probably belong to commercial or US military operators.

“It takes an incredible amount of competence to do something nefarious with drones.”

There have already been real-world consequences for the mechanical joyrides — such as when one of the drones disrupted a medevac helicopter set to airlift a patient.

The scores of sightings also led the Federal Aviation Administration to restrict drone flights over Picatinny Arsenal in Morris County and the Trump National Golf Club in Somerset.

“It’s a complete mystery,” Mark Chiarolanza, spokesman for the Morris County Sheriff’s Office, told NJ.com.

“The best way we’re going to figure this out is if somebody can get a good, solid picture of these things,” he said, adding that some of the drones’ large size indicates a recreational group isn’t behind this.

“We can’t knock these things out of the sky,” he continued.

Meanwhile, more drones were spotted above Staten Island Thursday, prompting politicians to urge the feds to figure out their origin, according to the Staten Island Advance.

People have seen them in eight counties since they were first spotted — from Bergen in the east to Hunterdon in the west, and near the Pennsylvania border — according to the Bergen Record.
