A Brooklyn man was sentenced Thursday to six months in jail for secretly recording “thousands of individuals” at a Nassau County sleep center and later destroying the evidence of his crime, officials said.
Sanjai Syamaprasad, 48, was accused of placing hidden cameras disguised as smoke detectors inside bathrooms at the Northwell Health Sleep Disorders Center in Great Neck, and in a public bathroom in the same building, according to the Nassau County District Attorney’s Office.
The scheme, which authorities said began in July 2023, ended in April 2024 after he was caught watching one of those videos at work.
Syamaprasad, who worked at the facility as a sleep technician at the time, would remove the cameras at the end of his shifts and transfer the images to an SD card.
A video obtained by the Daily News showed three round sticky tabs he appeared to have used to attach hidden cameras to a wall and a ceiling in one of the bathrooms.
In April 2024, NCDA detectives executed a search warrant at his Marine Park home and recovered multiple electronics, including phones, an SD card reader and three laptops.
Syamaprasad was arrested on April 25, 2024, after telling investigators that he “threw out the smoke detector in a garbage can at a CVS on Avenue U [and] broke up a small CD card and threw it in the same garbage pail.”
On July 15, 2025, Syamaprasad pleaded guilty to five counts of second-degree unlawful surveillance and two counts of tampering with physical evidence.
He was initially set to be sentenced to probation, but earlier this month, a judge said he would consider jail time.
On Thursday, Syamaprasad was sentenced to six months in jail followed by five months of probation. He will also be required to register as a sex offender.
While Nassau County District Attorney Anne Donnelly said she was hoping for a much harsher sentence, she noted that Syamaprasad will now experience the same treatment he inflicted on others.
“Sanjai Syamaprasad exploited these victims at their most vulnerable and he stole from them the security they are entitled to when seeking medical care,” she said. “Now, he will learn what it feels like to be watched, when correction officers are patrolling past his cell for the next six months.”
