Is this Invitation to Hell (1984)...?
From TV Tropes:
Invitation To Hell is a 1984 American horror movie for television by Wes Craven.
Tech engineer Matt Winslow (Robert Urich) has moved to a new town due to a lucrative job offer along with his family: wife Patricia 'Pat' Winslow (Joanna Cassidy) and his children Chrissy (Soleil Moon Frye) and Robbie (Barret Oliver). After settling in, various people in his social circle start pressuring him to join the Steaming Springs Country Club, which is run by one Jessica Jones (Susan Lucci), who is not quite what she seems...
The protagonist, Matt Winslow, works for a tech company developing a new type of spacesuit with a helmet that can scan the environment. In particular, it can distinguish between humans and non-humans, and presents this information on an on-screen display within the helmet. The antagonists in the film are identified as "non-humans" but are actually demons.
