Abstract. Video streaming from cameras, closed-circuit television (CCTV),
smartphones and Internet-connected objects (ICO) largely contributes to big data
trafc on the Internet. Video streaming provides enormous amount of useful
information for delivery of efcient and effective services in smart cities. Modern
cities have large networks of surveillance cameras including CCTV, street cross-
ings and the like. In this paper we discuss the challenges of annotating and
retrieving video data streams from vehicle-mounted surveillance cameras. We also
propose and evaluate the CityWatcher application - an Android application for
recording video streams, annotating them with location, timestamp and additional
context in order to make them discoverable and available to authorized Internet of
Things applications. One of such applications is based on crowdsourced alerts to
city authorities about road problems, like potholes, cracks, trafcaccidents.These
alerts are driver-initiated and are rewarded through an incentive mechanism.
OpenIoT platform is used for infrastructure and development support.

1 Introduction

Digital pervasive video cameras can be abundantly found everywhere these days and
their numbers grow continuously. Sometimes we need a video-recording of some road
accident (or of some other event) to understand what happened and identify a driver
who may have been at fault. Many car owners, not only in Russia but elsewhere, use
Vehicle-Mounted Surveillance Cameras (VMSC, or in other words, car black boxes,
video registers or smartphones) for recording their driving and events of interest. These
video-recordings are potentially valuable sources of data. Drivers can use video
recording from their devices as evidence in case of a road accident. However, video
recordings from VMSC can

' t be retrieved by others and shared. Besides, using
