He said: "I have always felt that video evidence should be used after a game for disciplinary matters.
"You can find things, you can protect players for the next game."
"Everyone will see that players have to be careful, they will say 'I can't do this again because I could be banned on what the video shows'," he said.
"To me it is clear, you do not need to change the game, you just need to analyse what has happened.
"If players get banned for three games the first week it is done, then three games on the second week and more on the third, it will soon stop.
"It will take just a few weeks of this type of action and things will change very quickly."
Benitez continued, "I don't want to talk about just Ronaldo or Torres. Skilful players must be protected. We need to help referees and we need to look at the video afterwards to see what has happened.
"Players will then know that there are cameras watching them. The video is really important. You can make mistakes during a game, but the video will allow things to be analysed."
Benitez said: "It is different talking about using technology to judge goals, which Fifa has rejected. To use technology for incidents in a game is valid.
"If a referee gives a yellow card for a tackle, or a yellow card for use of the elbow, and then afterwards you can see the intent, then why can the decision not be changed?
"A referee can say he made a mistake. And the next time, the next player will not do the same."
