Police Appeal For Footage
15 May 2019, 11:16 | Updated: 15 May 2019, 11:19
The appeal came as officers set up a facility allowing members of the public to send mobile phone and dash cam footage directly to the inquiry team.
Ms Faulds, 39, from Kilmarnock, was last seen on the evening of April 28 in Monkton, Ayrshire.
A man has appeared in court charged with her murder.
Ms Faulds' body has not yet been found and police have been concentrating their efforts to find her in the area of Barrhill, particularly along the A714 road between Girvan and Newton Stewart.
Detectives have been working with specialist search advisers and forensic officers as they try to locate her.
Meanwhile, the force helicopter is now being used to help map out the large search area from above to enable a more systematic search.
Officers said they are still interested in tracing the movements of two black cars on the A714 - a Mercedes and a Jaguar.
The Mercedes was seen on Monday April 29, while the Jaguar was sighted the following day.
In a statement, the force said: "Detectives believe the movements of these cars are central to the investigation and are appealing for the public's help in trying to find out more about them."
Police Scotland has also created an online link to allow people to send them any relevant video from their mobile phone or dash cam.

Detective Chief Inspector Martin Fergus, the officer leading the investigation, said: "What Emma's family is going through is unimaginable and our priority is to find her.
"I am thankful to members of the public who have been in touch and have provided us with valuable information which has led us to explore this area.
"I believe the A714 route is key to helping us find Emma and I am appealing again to those who use this route regularly, please take time to think back and consider if you saw a Mercedes or Jaguar car on this road or parked up somewhere, or even off road.
"If you have dash cam footage, please take the time to go through and check it. You may not realise it but you could have captured footage of the vehicles in these locations which could provide us with vital information and assist us in finding Emma."
Ross Willox appeared at Ayr Sheriff Court on Friday charged with murder and attempting to defeat the ends of justice.
The 39-year-old, of Ayrshire, made no plea and was remanded in custody.
