Big Brother: Celebrity Edition, 8 PM on Ch. 7 and

Ch. 12: Celebrity editions of the competition have been staged in foreign versions, but never in the American one ... until now. Familiar faces including Omarosa Manigault, singer-actor Mark McGrath, Keshia Knight Pulliam (“The Cosby Show”) and Ross Mathews become housemates in this new round, which will play out on multiple nights over several weeks instead of all summer. All of the show’s usual elements will be present, including Head of Household contests and evictions — and Julie Chen as host.

Animals With Cameras, A Nature Miniseries, 8 PM on Ch. 16 and Ch. 48; 1 AM

on Ch. 16 and Ch. 48: In this new three-part series, many of the creatures featured actually are outfitted with cameras ... the idea of the program being that their perspective serves as the “lens,” to enable viewers to see the world through the point of view of the showcased animals. In this first episode, cheetahs, seals and baboons are among those serving as guides — though they may be more concerned with their own survival than with serving the audience.

Channel Zero: Butcher’s Block, 10 PM on SYFY;

3 AM on SYFY: Inspired by Kerry Hammond’s creepypasta chiller “Search and Rescue Woods,” this horror anthology series opens a new tale with the season premiere “Insidious Onset,” which introduces Olivia Luccardi (“It Follows”) as Alice, an idealistic young woman who looks forward to moving to the city. When she and Zoe (Holland Roden, “Teen Wolf ”) arrive in the metropolis, however, they soon notice several eerie disappearances that seem to be tied to a mysterious staircase in a sketchy neighborhood. Brandon Scott and Rutger Hauer also star.
