Stingrays are particularly controversial because almost nobody outside police or law enforcement knows what they can do or how they work, and they are frequently used in criminal proceedings and prosecutions.
What we do know is that these devices spoof cell towers to trick phones into connecting to them, which allows police to vacuum up phone calls and text messages, as well as a suspect's location.
New York's bill will require law enforcement to obtain a warrant before deploying a stingray, according to an analysis of the bill by the Tenth Amendment Center.
That alone would compel state law enforcement to follow the same guidance as federal agents who must obtain a warrant before using a stingray device, as per Justice Department guidance issued two years ago.
The bill allows police to skip getting a warrant in emergencies, such as a risk to life or serious injury, but in these cases police would have to obtain a court order within three days of collecting the data or risk it being destroyed.
