Method Apparatus and System of Remote Monitoring
Embodiments of the present invention provide a method, apparatus and system of remote monitoring. The apparatus according to some demonstrative embodiments of the invention may include a camera positioned to capture an image within a field of view including a monitored area; a transmitter to transmit data corresponding to the image over a communication channel during a transmission time period; and a blocking arrangement to selectively block at least part of the field of view during at least part of said transmission time period, in a conspicuous manner. Other embodiments are described and claimed.
1 . A monitoring unit comprising:
a camera positioned to capture an image within a field of view including a monitored area;
a transmitter to transmit data corresponding to said image over a communication channel during a transmission time period; and
a blocking arrangement to selectively block at least part of said field of view during at least part of said transmission time period, in a conspicuous manner.
2 . The monitoring unit of claim 1 , wherein said blocking arrangement is to selectively block at least part of said field of view based on a control signal indicating said data is being transmitted over said channel.
3 . The monitoring unit of claim 2 , wherein said blocking arrangement comprises:
a shutter to be positioned in at least first and second positions, said shutter, when in said first position, at least partially blocks said field of view; and
a controller to controllably move said shutter between said first and second positions based on said control signal,
wherein a difference between said first and second positions is conspicuous to an observer in said monitored area.
4 . The monitoring unit of claim 3 comprising a position maintainer to maintain said shutter in a selected one of said first and second positions independently of said control signal.
5 . The monitoring unit of claim 2 , wherein said blocking arrangement comprises a controller to controllably move said camera between at least first and second positions based on said control signal, wherein when in said first position, said camera has a field of view not including at least part of said monitored area, and wherein a difference between said first and second positions is conspicuous to an observer in said monitored area.
6 . The monitoring unit of claim 5 , wherein said first and second positions comprise first and second orientations about a rotation axis of said camera, said controller is able to controllably rotate said camera between first and second orientations.
7 . The monitoring unit of claim 6 , wherein when in said first orientation, said camera is directed towards a predetermined surface.
8 . A method of monitoring an area comprising:
positioning a camera to capture an image within a field of view including a monitored area;
transmitting data corresponding to said image over a communication channel during a transmission time period; and
selectively blocking at least part of said field of view during at least part of said transmission time period, in a conspicuous manner.
9 . The method of claim 8 comprising generating a control signal indicating said data is being transmitted over said channel, wherein said selectively blocking comprises selectively blocking at least part of said field of view based on said control signal.
10 . The method of claim 9 comprising:
controllably moving a shutter between first and second positions based on said control signal,
wherein said shutter, when in said first position, at least partially blocks said field of view, and wherein a difference between said first and second positions is conspicuous to an observer in said monitored area.
11 . The method of claim 10 comprising maintaining said shutter in a selected one of said first and second positions independently of said control signal.
12 . The method of claim 9 comprising controllably move said camera between at least first and second positions based on said control signal, wherein when in said first position, said camera has a field of view not including at least part of said monitored area, and wherein a difference between said first and second positions is conspicuous to an observer in said monitored area.
13 . The method of claim 12 , wherein said first and second positions comprise first and second orientations about a rotation axis of said camera, and wherein controllably moving said camera comprises controllably rotating said camera between first and second orientations.
14 . The method of claim 12 , wherein when in said first orientation, said camera is directed towards a predetermined surface.
15 . A monitoring system comprising:
a monitoring station; and
at least one monitoring unit comprising:
a camera positioned to capture an image within a field of view including a monitored area;
a transmitter to transmit to said monitoring station over a communication channel, data corresponding to said image during a transmission time period; and
a blocking arrangement to selectively block at least part of said field of view during at least part of said transmission time period, in a conspicuous manner.
16 . The monitoring system of claim 15 , wherein said blocking arrangement is to selectively block at least part of said field of view based on a control signal indicating said data is being transmitted over said channel.
17 . The monitoring system of claim 16 , wherein said blocking arrangement comprises:
a shutter to be positioned in at least first and second positions, said shutter, when in said first position, at least partially blocks said field of view; and
a controller to controllably move said shutter between said first and second positions based on said control signal,
wherein a difference between said first and second positions is conspicuous to an observer in said monitored area.
18 . The monitoring system of claim 17 comprising a position maintainer to maintain said shutter in a selected one of said first and second positions independently of said control signal.
19 . The monitoring system of claim 16 , wherein said blocking arrangement comprises a controller to controllably move said camera between at least first and second positions based on said control signal, wherein when in said first position, said camera has a field of view not including at least part of said monitored area, and wherein a difference between said first and second positions is conspicuous to an observer in said monitored area.
20 . The monitoring system of claim 19 , wherein said first and second positions comprise first and second orientations about a rotation axis of said camera, said controller is able to controllably rotate said camera between first and second orientations.
21 . The monitoring system of claim 20 , wherein when in said first orientation, said camera is directed towards a predetermined surface.
