Ambulances could be fitted with CCTV to protect paramedics from attack and help bring prosecutions.
The move is being considered by the East of England Ambulance Trust after a gang tried to force their way inside an ambulance in Ipswich last weekend.
Paramedics were treating two men near the railway station when a group of men tried to get inside their vehicle.
Trust spokesman Matthew Ware said cameras were now fitted to emergency vehicles in other parts of the UK.
He said: "It is not something which is currently on the agenda but, in common with all health, safety and security issues, it is regularly reviewed.
"We would have to weigh up how effective CCTV would be in preventing violent incidents and how it could be used while protecting patient confidentiality."
Mr Ware said it is unlikely that security cameras would have proved useful during the attack at Ipswich because all the violence took place outside the ambulance.
"It is questionable whether the types of people who generally cause problems - people under the influence of drink or drugs or those with psychiatric problems - would be deterred by CCTV," he said.
