An almost one-minute CCTV clip released on Thursday shows the fugitive sporting a red cap and blue and yellow work gear, while casually vaping outside Lake Cargelligo police station on January 22.
In accompanying images, police point to a number of tattoos on his arm including a distinctive demonic image.
The footage was disclosed after NSW Police Commissioner Mal Lanyon pledged to find the fugitive, who has been on the run for a week after a deadly alleged domestic violence-related shooting spree.
Ingram allegedly killed three people, including his pregnant former partner Sophie Quinn and her aunt Nerida Quinn, in the western NSW town of Lake Cargelligo hours after the police station visit.
Family friend Leisa-Ann Kilby, who knew Sophie when she was a child, said she was still coming to grips with her death.
"She was just a fun, loving girl who loved her dogs. She was a typical country girl, just enjoying life," she told AAP.
"It's going to take a long time to come to terms with it."
The 50-year-old early childhood educator has organised a fundraiser for Sophie's family which had topped $16,000 by Thursday afternoon.
Specialist riot squads are being deployed to assist in the search, which has entered its second week, and all leads are being investigated, police say.
"I want to make sure that not only are you safe, but you feel safe," Mr Lanyon said.Â
"You will continue to see a significant policing presence until such time as we put Mr Ingram before the court."
Assistant Commissioner Andrew Holland said there had only been one reported sighting of Ingram, although police were investigating the lead of a motorcyclist who didn't stop for officers.
The white getaway ute the 37-year-old had been driving could be hidden, he noted.
The earlier tip-off, from Sunday morning, led investigators to focus on the areas surrounding the remote outpost of Mount Hope, a former mining town about 90km northwest of Lake Cargelligo.
Police warned they would arrest and prosecute anyone helping the experienced council worker to access food and water amid a heatwave across the outback region.
The tricky terrain with ample hiding spots between sheds and vast properties, some of which exceed 160 square kilometres in size, is posing challenges for officers.
"All members of the community should exercise extreme caution," Mr Holland said.
"They need to be aware that there is a gunman on the loose in their area."
Ms Quinn, 25, and her friend John Harris, 32, were killed when bullets were fired into a dark hatchback on Lake Cargelligo's Bokhara St about 4.20pm.
Soon after, her 50-year-old aunt was shot dead at a home on Walker St, a two-minute drive away.
Kaleb Macqueen, 19, was also shot at the home but survived with serious injuries.
Suspicion and tensions are high as the search for the alleged triple killer grips the town of about 1100 people and surrounding region.
The openness of the terrain, particularly compared to the alpine-country search for fellow fugitive Dezi Freeman in Victoria, should allow police to conduct a more thorough search for longer, according to one expert.
Domestic and family violence remained a scourge on the community and its eradication was a personal focus, the state police commissioner said.
"A tragedy like this brings domestic and family violence into the picture even more," Mr Lanyon said.
