Background for Video delivery systems with wireless cameras
This document is about video delivery systems and techniques that use wireless cameras.
Network camera systems may be built on the Internet Protocol (IP), and can use Ethernet-based networking technology. Network camera systems have been replacing closed circuit television (CCTV), in some cases, due to several factors such as accessibility, ease of use, cabling scalability and lower costs of deployment and operation. Wireless network cameras systems, such as WiFi networks based on IEEE 8021.1 standards and emerging WiMAX networks based upon IEEE 8021.6 standards are becoming more popular and will soon be the most widely used platform for video surveillance applications.
An IP surveillance system may include IP cameras that are connected to a switch via twisted pair cabling. The network connection can also be made using wireless local area networking technology (LAN), such as the IEEE 802.11b standard. IP cameras can be configured to allow remote clients and observers to connect to the camera using standard TCP/IP interface standards like FTP or HTTP. IP-based network camera systems are possible to be built using components that can be purchased off the shelf (COTS) from a variety of suppliers.
This document discusses various aspects of video delivery systems using wireless camera and methods for providing such systems.
Systems, apparatuses and techniques for video delivery may include the following: A wireless camera placed in a wearable form factor with a battery, configured to generate a live video feed and a basestation in wireless communication with it. The base station is configured to receive and process the wireless video feed and to connect with the portal device. It can also be configured to transmit at least some of the processed video stream to remote clients.
Systems, apparatuses and techniques for video delivery may include a wireless camera that is placed in a wearable form factor. It can also include a battery to provide energy as well as a base station in wireless communications with the wireless camera. The wireless camera can be set up to create a video feed and to operate a radio to transmit at most a portion of it over a first wireless channel. A second radio can then operate in a polling mode to obtain information over a second wireless channels. The base station can receive the video feed from wireless camera. The base station can reserve the first channel wirelessly for the wireless camera. This means that the base station transmits information over the second channel to the wireless cameras to tell them to transmit on the first channel at a specific time. The base station can process the video feed and transmit the processed feed to a portal for remote viewing.
These, along with other aspects, may include one or more the following features. A base station can be set up to detect the existence of a wireless channel by transmitting a wireless signal to a nearby node within wireless range to cause it to cease transmitting wireless data messages to the wireless camera. The size of the wireless data message can be larger than the size of the signaling messages, e.g. by at least 100 to 1. A vehicle can be used to house one or more base station.
The wireless camera can have a first radio to transmit a minimum portion of the video feed over a first wireless channel and a second radio that uses polling mode to receive information over a second wireless channel. A burst transmission device can be included in the wireless camera to transmit information to the base station. The burst transmission units generate orthogonal frequency division modulation transmission symbols. The burst transmission units generates transmission symbols for data rates of up to 65 Mbps. The burst transmission device can generate transmission symbols for data rates exceeding 22 Mbps. Multiple output circuits can be included in the burst transmission unit. Each circuit may have a different power amplifier bias setting. Each output circuit can have a power amplifier or antenna matching circuitry. A wireless link condition can be used to configure the burst transmission unit to choose one of the output circuits that will allow data transmission. By transmitting on the first channel wirelessly, the base station can reserve the first channel for wireless cameras. The base station can transmit information over the second wireless channel to the wireless camera, instructing it to transmit on the first channel at a specific time. A user control can be added to the wireless camera to indicate interest to the base station. The wireless camera can be accessed by the video portal device, which generates a user notification based on access. A capacitor holding circuit can be added to the wireless camera to prolong battery life and allow for current surges when transmitting data to the base station. A direct-sequence spread frequency (DSSS) receiver can be added to the second radio of the wireless cam. The second radio can be set up to run continuously for longer periods than five hours and draw less than 50 microwatts per hour.
Systems, apparatuses and techniques for video delivery may include a wireless camera sensor that captures video, and a base station that operates a transceiver to detect a wireless channel. The base station transmits a wireless signal to a nearby node within wireless range to make the wireless channel unavailable. This causes the wireless camera to transmit a signal message to the wireless node indicating the availability of the channel. The base station can be set up to receive and process the video from the wireless camera, allowing remote viewing.
These, as well as other aspects, may include one or more the following features. The CSMA/CA protocol can be based on an 802.11 standard in some implementations. The size of the wireless data message can be larger than the size of the signaling messages, for example, at least 100 to 1. The wireless camera node can operate a receiver that is capable of receiving the signaling messages for one or more periods. This includes extended periods of video transmissions, which average less than 5%. To transmit wireless video data, the wireless camera node uses a 2.4GHz radio spectrum. To transmit the wireless video message, the wireless camera node can use Orthogonal Frequency domain Modulation (OFDM). The wireless camera can be powered from solar or battery power. You can arrange the wireless camera node in a wearable format. It can weigh less than 100g or less than 50g.
A wireless camera may include an image sensor to capture video and a radio to transmit the video to a basestation over a wireless channel. The base station can reserve the wireless channel by transmitting data on the channel. There is also a second radio that receives communications from the base stations. A controller is in communication with the controller and is configured to control the radio to transmit the video feed to the basestation in response to the signaling message. A second radio can be set up to work in a polling mode. This allows the receiver to receive a signaling message indicating the availability of the wireless channel.
Systems, apparatuses and techniques for video delivery include: obtaining video from one to many battery-powered and wearable wireless camera, each one of which includes an internal battery to provide power; transmitting the video to a basestation that is separate from the wireless cameras and in wireless communications with them; processing the video in the base station; and transmitting it for remote review.
These, along with other aspects, may include one or more the following features. Remote clients can be charged for access to the video portal and the ability to view video from one or more wireless cameras. The wireless transmission of the processed video can be used to transmit it to a portal. The video portal can issue a command to access the wireless camera. Operating the wireless camera can be used to send an alert to the user about the video portal’s accessibility. You can also transmit a message to reserve the wireless channel and send the video. Clear-to-send information (CTS) or self-signing information can be included in the message. The transmission of the processed video can be done to remote review.
