Bilic's claim comes after a report into referee mistakes said West Ham have been cost by eight mistakes by referees this season - which would have been enough to put them equal on points with third and fourth-placed Manchester City and Arsenal in the Premier League.
But while Bilic did not comment on the report, he did say it would be a good idea to help referees with more technology, provided it did not interfere with the flow of a game.
"For me there is no other option but technology," the former Croatia coach said.
"Although it has to be up to some limit.
"There is no pause or stop in the game and they are connected with watches or signals or whatever.
"It has to be the sort of technology which doesn't affect the game. Because if the game loses its flow, well I'd rather have these mistakes."
West Ham are eight points off the top four, trailing fifth-placed Manchester United by three, with four games remaining in their Premier League campaign
The London club's home run includes a clash against United - West Ham's last outing at Upton Park before moving to the Olympic Stadium ahead of next season.
