Assistant Commissioner of NSW Police, Michael Corboy, told local media that the system will "change the culture" on the state's roads.
For the first three months, drivers caught illegally using a cell phone will get a warning, after that offenders will receive steep fines and penalty points on their driver's license.

The cameras employ artificial intelligence to overview photos and detect illegal employ of the devices, in step with Transport for NSW, and authorities device to maintain 135 million footage of vehicles per year.
The state wants to cut the number of road fatalities by 30% by 2021, Reuters said.
This morning, the Hit Network's AB & Ben asked NSW Roads & Transport Minister Paul Toole every question about the new mobile phone detection cameras, including what exactly drivers can and can't do.
All other functions, such as video calling, using social media and photography, playing audio while driving are only legal if a driver has parked their vehicle outside of traffic.More news: Jaguars QB Gardner Minshew to start vs. Chargers
"Independent modelling has shown these cameras could prevent around 100 fatal and serious injury crashes over five years", Carlon said. Officials said that a trial of the technology earlier in the year had caught more than 1,00,000 drivers illegally using a phone at the wheel.
Unlike with speed cameras, there will be no warning signs to alert drivers to the presence of the mobile detection cameras. After the three months, you'll be slapped with a $344 fine if you're caught, or a $457 fine in a school zone. In both cases, drivers will also receive penalty points.
"There is strong community support for more enforcement, with 80 per cent of people surveyed supporting use of detection cameras to stop illegal mobile phone use", Carlon added.
Around 10 fixed and portable cameras have been switched on around the state, with 45 cameras expected to be operational within the next four years.More news: Taliban hostage: Navy SEALS 'missed us only by hours' during rescue attempts
