The partnership running the current system in Rhyl, Prestatyn and Rhuddlan say it is not sustainable and has agreed to pass it to Cheshire West and Chester council.
The scheme will see 32 prioritised cameras beamed to England.
If anything is spotted, officers will alert North Wales Police immediately.
The system in the towns was run and funded by Denbighshire council until 2015.
County council spending cuts saw it passed to a partnership of Denbighshire, three town councils and North Wales Police about a year ago for a trial period.
In the last 12 months, the cameras have been operational 24 hours a day but have not been monitored full-time, with crime figures in the area remaining much the same.
The network's server at Rhyl police station is said to be beyond its serviceable lifetime and, with a replacement costing about Â£80,000, grants are being sought.
The partnership board prioritised 32 cameras in the three towns according to their importance in tackling crime and disorder and their contribution to the community.
Ranked as lower priority, the remaining 48 cameras will not be repaired or replaced if they break.

Nottinghamshire Police were present when the man fell from a building in the Radford area of Nottingham on Friday evening.
A witness told the Nottingham Post he survived the first fall before running to another flat and falling again.
Police are not treating the death of the man, in his mid-30s, as suspicious.
Officers were called to Waterloo Road at about 19:30 GMT.

The 80ft (24.3m) structure will be located on a raised part of the seafront in Redcar, at the site of the former Leos night club.
It will have a viewing platform, a studio, galleries and a cafe.
Work is due to start on the town's sea defences in early 2011, and the construction of the vertical pier is set to begin in the autumn.
Councillor Sheelagh Clarke, cabinet member for culture, leisure and tourism, said: "The public told us that they wanted to see unique attractions in Redcar that do not replicate those of other resorts.
"The vertical pier will create a point of interest to attract people to Redcar and re-ignite interest in the town as a place to visit."
The monitoring of CCTV cameras in three north Wales towns will be handed across the border to Chester.
