Six fire engines and around 40 firefighters were called to a fire on The Hale in Chingford.
A garage, an outbuilding and two motorbikes were destroyed. A small part of the ground floor of two houses were also damaged by fire. There were no reports of any injuries.
The Brigade's Control Officers took the first of almost 70 calls to the fire at 2047 and used GoodSam to live stream incident footage from smart phone cameras to provide better situational awareness.
When a 999 call is received by the Brigade, the caller may be asked if they would like to provide a live video stream of the scene using their smartphone. The Control Officer will send a text message with a secure, one-time-use link that opens a live stream direct from the phone to the Control room.
Fire crews from Walthamstow, Woodford, Chingford, Leyton and surrounding fire stations attended the incident, which was under control by 2133.
The cause of the fire is under investigation.
