Tech lawyer Luke Scanlon from Pinsent Masons law firm said security could be an issue if this technology is software-based.
"'Detect and avoid' systems rely on software and given the current climate of hacking and data breaches, it is very important that co-ordinated efforts are made to ensure that systems are put in place which are given the highest level of assurance in terms of security," he said.
"Once these standards are agreed by technical experts, arguments to support the creation of commercial drone services beyond the line of sight will gain more support in the ongoing regulatory reform discussions and forums currently taking place."
Amazon said it would not launch the service until it was able to "demonstrate safe operations".
The US Federal Aviation Authority (FAA) has strict criteria for commercial drone use and some American politicians have called for the setting up of a drone register.
The FAA estimates that by 2020 there will be around 30,000 commercial drones and many more civilian devices in use in America.
