A man has been shot and killed after answering the front door of his Canberra home overnight.

Emergency crews were called to the Mansfield Place property in Phillip just before midnight after police received reports of shots being fired.

They found a 48-year-old man at the scene with a single gunshot wound. He was taken to hospital but later died.

He opened the front door, with the alleged killer firing a single shot before fleeing the scene.

Detectives from ACT Police and the AFP remain on the scene.

Criminal Investigations Detective Inspector Marcus Boorman said a woman was home with the man at the time of the shooting but was not injured.

"Detectives are investigating the circumstances of this incident; however, at this time the reason for the attack is yet to be established," he said.

"Police have identified evidence from the scene, all of which will be forensically examined.

"We've spoken to a number of witnesses in the area and would encourage anyone who has information about the shooting to come forward to police."

The shooting is hauntingly similar to the one in Stockton in NSW on Wednesday night when a 61-year-old grandmother was shot dead after answering her front door.

Stacey Klimovitch was shot and killed at her home near Newcastle about 8pm on Wednesday.

Police are urging people to come forward with any information they may have, including dashcam or security vision from the area.

It is understood Klimovitch had a brief argument with the shooter before the weapon was fired through the screen door.

The attacker fled on foot and remains on the run.

Speaking to 2GB's Ben Fordham, NSW Police Detective Superintendent Wayne Humphrey described the incident as a "targeted" shooting.

"A number of persons were spoken to, persons that could be termed 'persons of interest'," he said.

"At the moment there are no charges and everyone remains a suspect."

In a major development, he said police had footage they believed captured the suspect, but they were seeking more dashcam footage to help crack the case.

"We have some vision we think is the person, but we are (after) dashcam vision because that's the one that will pick the person up walking along the street that a house (CCTV) might miss," Superintendent Humphrey said.

Earlier, police said they had "a number of lines of inquiry".
