The lockbox contains a microcomputer used in the processes of validating preapproved credentials. One method of obtaining access to the lockbox is by user carrying only an identification card, the lockbox scanning the identification card and transmitting its data to the lockbox's server for validation via an internal cell phone modem's connection through cell towers. The lockbox is also capable of capturing video and audio recordings, storing and categorizing the recordings into data such as traffic or noise levels over varying periods of time; and such data can be transferred to a user's cell phone upon the owner's approval. Additionally, the lockbox is powered by a solar panel power source, making it self-sustaining.
