Abstract

Described is a method for registering and executing instructions in a video capturing device and to a door station. The method comprises receiving at a video capturing device a signal(s) representing a first input made using an authorized device, generating a graphical representation of the received signal(s), superimposing the graphical representation onto video captured by the video capturing device and streamed to the authorized device, receiving at the video capturing device, after the signal(s) representing an input made at the authorized device have been received and graphical representations have been generated and superimposed onto video captured by the video capturing device and streamed to the authorized device, a concluding signal representing a concluding input made using the authorized device, translating, in response to said concluding input, the received signal(s) into an instruction executable by the image capturing device, and executing the instruction resulting from the translation of the signal(s).

Claims

1. A method for registering and executing instructions in a video capturing device, comprising:

receiving at a communication interface of the video capturing device at least one signal representing a first input made using an authorized device,

generating at the video capturing device a graphical representation of the at least one received signal, superimposing at the video capturing device the graphical representation onto video captured by the video capturing device and streamed to the authorized device,

receiving at the video capturing device, after the at least one signal representing an input made at the authorized device have been received and graphical representations have been generated and superimposed onto video captured by the video capturing device and streamed to the authorized device, a concluding signal representing a concluding input made using the authorized device,

translating, in response to said concluding input, the received at least one signal into an instruction executable by the image capturing device, and

executing the instruction resulting from the translation of the at least one signal.

2. The method according to claim 1, wherein the instruction represented by the at least one signal is an operation requested by a user of the authorized device.

3. The method according to claim 1, wherein said received at least one signal represents a symbol inputted by an operator of the authorized device.

4. The method according to claim 2, wherein said received at least one signal represents a symbol inputted by an operator of the authorized device.

5. The method according to claim 3, wherein said superimposing of the graphical representation onto the captured video of the video stream includes changing pixel values for pixels forming the symbol in the video stream.

6. The method according to claim 2, wherein said superimposing of the graphical representation onto the captured video of the video stream includes changing pixel values for pixels forming a visual representation of said requested operation.

7. The method according to claim 1, wherein the received at least one signal and the received concluding signal are in the form of DTMF-signals.

8. The method according to claim 1, wherein a communication session between the video capturing device and the authorized device is a SIP-session (Session Initiation Protocol).

9. A method for controlling entry to an area, comprising:

the method for registering and executing instructions according to claim 1, wherein the video capturing device is a door station,

receiving, at the door station and before receiving at least one signal representing a first input made using the authorized device, an input representing a request for a communication session with an authorized device being authorized to grant entry to the area,

sending to the authorized device, in response to receipt of said input representing a request, a request for setting up the communication session, and

generating an entry control signal in response to the receipt of the at least one signal and the concluding signal from the authorized device.

10. The method according to claim 9, wherein the entry control signal is sent from the door station to a physical access controller controlling entry to said area.

11. The method according to claim 9, wherein the input that is representing a request for a communication session is generated by physical interaction with a device mounted in the door station.

12. The method according to claim 10, wherein the input that is representing a request for a communication session is generated by physical interaction with a device mounted in the door station.

13. The method according to claim 9, wherein the concluding signal received is a confirmation signal received from the authorized device in response to a confirmation input made at the authorized device.

14. A door station, comprising:

a camera for capturing images of person in front of the door station,

an input device for initiating communication with a controlling device,

lock output configured to carry a passage lock signal,

communication transceiver configured to sending video to the controlling device and receiving signals representing an instruction,

a video overlay device configured to generating a graphical representation of a signal received via the communication transceiver and overlay the video to be sent via the communication transceiver with the generated graphical representation, and

an instruction execution device configured to execute a received instruction in response to a concluding signal received at the transceiver, wherein said communication between the door station and the controlling device is a SIP-session (Session Initiation Protocol).

15. The door station according to claim 14, wherein the signal representing an instruction and the concluding signal are in the form of DTMF-signals.

16. The door station according to claim 14, wherein the lock output and transceiver is the same device.

17. The door station according to claim 14, wherein the lock output receives the passage lock signal from the controlling device.
