This paper presents a device for the blind people that provide navigation and real time monitoring. The key idea behind the development of the device relies on providing navigation using GPS receiver with user required location names announcement and user relatives or a remote operator can provide real time assistance by monitoring the video transmitted by a RF camera. The RF camera at the user side acts as a transmission section continuously transmits video streams to RF receiver, acts as a receiving section. The RF receiver with antenna receives the video streams and displays it on the computer monitor using XGA TV box. The receiving video on the computer also contains the audio of the user. By hearing the audio of the user in the video, user relatives or a remote operator provides immediate assistance by identifying the user current staying locations and surroundings during the emergency conditions such as need of any medical help or in unsafe situations
