Question: do all traffic lights have a red light camera

Answer: No, Since the early 1990s, red light cameras have been used in the United States in 26 U.S. states and the District of Columbia. Within some states, the cameras may only be permitted in certain areas. For example, in New York State, the Vehicle and Traffic Law permits red light cameras only within cities with a population above 1 million (i.e. New York City), Rochester, Buffalo, Yonkers, and Nassau and Suffolk Counties. In Florida, a state law went into effect on 1 July 2010, which allows all municipalities in the state to use red light cameras on all state-owned rights-of-way and fine drivers who run red lights, with the aim of enforcing safe driving, according to then-Governor Charlie Crist. The name given to the state law is the Mark Wandall Traffic Safety Act, named for a man who was killed in 2003 by a motorist who ran a red light. In addition to allowing the use of cameras, the law also standardizes driver fines. Major cities throughout the US that use red light cameras include Atlanta, Austin, Baltimore, Baton Rouge, Chicago, Dallas, Denver, Los Angeles, Memphis, New Orleans, New York City, Newark, Philadelphia, Phoenix, Raleigh, San Francisco, Seattle, Toledo, and Washington, D.C. Albuquerque has cameras, but in October 2011 local voters approved a ballot measure advising the city council to cease authorizing the red light camera program. The City of Albuquerque ended its red light program on 31 December 2011.
