Flock, the US surveillance firm, is rolling out new safeguards to prevent police misuse of its technology which, its founder and chief executive admits, should have happened sooner.
Police have used Flock to track romantic partners , external and stalk strangers, leading to growing public backlash against the company. It has also been used to find stolen cars and missing people.
Asked whether it had taken Flock too long to protect tens of thousands of its cameras, licence plate readers and drones from police abuse, Garrett Langley said: "Yeah... yes."
Flock is cutting the number of days most data is retained, from 30 days to seven and abnormal searches and uses will also automatically be flagged.
Flock cameras have been used by police to not only track former and current romantic partners, but in one case, even a woman who had had an abortion , external .
Police across the US have quit , external or been fired , external for misuse of the technology.
A man in Indiana recently told local news he found out through a public records request that police had set a Flock alert , external for his vehicle, despite not being suspected of any wrongdoing.
At least 50 cities have this year cut ties with Flock , external due to a public backlash.
However, Langley told the BBC that another 16 cities that had turned off Flock services have in the last three months come back to the company. Generally, it's running at a 7:1 ratio of new customers to lost customers, he said.

Langley said that, just six months ago, he asked in a meeting of the company's board why there seemed to be a growing public focus on Flock.
This was around the time that Amazon's Ring, a doorbell camera firm, cancelled a partnership with Flock after an outcry over a Super Bowl advert which sparked concern about unwanted surveillance.
"Historically, my point of view as a chief executive of a private company was, I don't know if I should be making these decisions. I don't know if it's my job to say how long data should be retained," Langley said.
He added that he has come to agree with groups like the American Civil Liberties Union and the Electronic Frontier Foundation that police should need an active case number to search Flock's data.
"They're right. I think it should be required."
He added: "Our employees and communities have said loud and clear, they expect companies like Flock to have a stronger point of view as the expert. I resisted that because I didn't want to have that responsibility."
Cooper Quintin of the EFF described Flock's new changes as "piecemeal, voluntary, and reversible" updates that "fall short" of meaningful protection of peoples' privacy.
"Simple safety 'feature updates' can and will be circumvented", Quintin said. "Invasive searches like [automated license plate reader] database queries must require a judicial warrant."
Langley says he has now accepted responsibility for more control over the uses of Flock. At the same time as he is strengthening Flock's safeguards, he is pitching his company's products as crucial to combatting crime and improving policing in the US.
Cities that don't use Flock are effectively choosing "to be less safe", he claimed.
Nevertheless, he does not deny…
