The department has historically been known to quickly embrace new technologies. The Marine Bureau began in 1933 with the gift of an 18-foot Chris Craft mahogany speedboat from the residents of
Manhasset Bay. The Aviation Bureau followed a year later with the gift of a Stinson airplane from wealthy county residents. The aircraft was grounded by World War II, but the air unit was revived in 1968 with the purchase of four helicopters to assist in pursuits and medical evacuations. The elite Highway Patrol Bureau, which covers the
Long Island Expressway and the
Seaford-Oyster Bay Expressway and includes motorcycle officers, was founded in 1935. All police vehicles are now equipped with computer keyboards, and, since 1973, air conditioning. In addition to these units, the department also maintains many features, such as a Detective Bureau, a police academy, a mounted unit, an arson/bomb squad, a hostage negotiation team, a citizen-based
auxiliary police program, a bureau of special operations (SWAT and anti-crime combined) and an
Emergency Services Unit (ESU), that are usually found only in the police departments of large cities. The department has also adopted its own system for computerized tracking of crime information known as NASSTAT, now called Strat-Com. Traffic safety is a major department priority, given Nassau's relative lack of public transportation and its perpetually clogged roads and highways. A unique feature of the department is its
Children's Safety Town, an actual village built to 1/3 scale that includes paved streets, two intersections equipped with traffic signals, an overpass, two tunnels, a simulated railroad crossing and 21 buildings. Managed by the department's Traffic Safety Unit, it allows the NCPD to teach traffic and bicycle safety to grade schoolers under controlled conditions. In July 2025, the department went a step further and opened its "Training Village," a model neighborhood that aims to train officers based on realistic scenarios. The village has about 10 buildings, including a warehouse, gas station and grocery store. The idea for the village came about when the department realized that classroom and academy-based training wasn't adequately preparing officers for the unpredictable realities of daily police work. The village allows trainers to stage a wide variety of incidents, from active shooter and hostage situations to more routine disturbances. In 1989, concerned about the increasingly heavy weaponry being carried by criminals, the NCPD was among the first police departments in the country to trade their venerable 6 shot .38
Smith & Wesson revolvers for the 15-round, nine-millimeter
SIG P226 semi-automatic pistol. In 2009, the department announced it is switching over to the
SIG P229 and
SIG P226, chambered for .40 S&W with the
Double Action Kellerman (DAK) trigger and integral accessory rail as the new standard firearm. In September 2023, the NCPD began transitioning to the Glock Model 45, chambered in 9mm. Also, officers are re-equipping with expandable batons to replace the straight wooden nightstick. In 1995, the NCPD became the largest police department in the country to that time, and the first in New York State, to allow its officers to work a steady 10- or 12-hour shift, rather than a rotating 8-hour shift commencing at a different time each week. In early 2007, the NCPD announced that 207 marked patrol vehicles would be equipped with Global Positioning System (GPS) devices, allowing "live" views of the location of all active units. In late 2006, the department undertook "Operation Gotcha," deploying
a new technology that scans the license plate numbers of passing vehicles directly into a mobile crime computer, allowing the immediate apprehension of drivers operating vehicles with expired licenses, suspended registrations or with outstanding arrest warrants. The technology allows the scanning of literally thousands of plates in a single shift.

Glock 45 9mm Police vehicles In the 1990s, the department exclusively used
Ford Crown Victorias and
Chevrolet Caprices as their main patrol cars.
Mounted units used
Chevrolet Suburbans. In 2003, the department switched to the 2000–2005
Chevrolet Impala 9C1. The Ford Crown Victoria was still purchased, albeit in smaller quantities. The department favored the "CVPI" due to the
rear-wheel drive and
V8 configuration. The department switched back to the Crown Victoria in 2006. Few Impalas are still in service in 2019. Model year 2006–2010
Dodge Chargers were tested for highway patrol use. The
Dodge Charger was a performance leader; however, due to maintenance costs, the department did not use many and few are still in service as of 2018. The department tried
Chevrolet Tahoes in 2010 and they were given to certain sectors. The vehicle proved to be a strong patrol car with good all-weather capability and was a valuable asset during
Hurricane Sandy. The
Chevrolet Caprice 9C1 was tried out in 2014 and was given to precincts and highway patrol. The mounted unit operates Chevrolet Tahoes and Suburbans. Highway patrol utilizes the Ford Police Interceptor, Ford Crown Victoria, Chevrolet Caprice and Dodge Charger. The Auxiliary Police unit uses a variety of ex-marked Nassau County Police cars, the majority of which being Ford Crown Victorias and Chevrolet Impalas. Nassau County Highway Patrol now utilizes 2021-2022 Dodge Chargers and Late model Chevrolet Tahoes for patrol. Nassau County ended up switching to the
Ford Utility Interceptor as their main choice for
RMP. Today, the
Ford Utility Interceptor is the most widely used car in the fleet. Image:NCPD Patrol Vehicle.jpg|
