Device for sending image data from camera to CCTV network
First Claim
1. An imaging device, comprising:
- a camera lens formed from infrared transmitting material;
an infrared sensor, wherein the infrared sensor and the camera lens together record infrared images;
an image processing circuit including a compression circuit that outputs compressed image signal data corresponding to the recorded infrared images;
a microcontroller that controls circuits, including the image processing circuit;
a storage device that stores image signal data, including compressed image signal data;
a network adapter that communicates with a networked device capable of serving files via an internet-protocol address;
a first transmission mode routine that sends single image data files via a connection-oriented protocol, said connection oriented protocol employing a first packet header type; and
a second transmission mode routine that streams image data files employing a second packet header type having less data than said first packet header type.

Abstract
An integrated Internet camera includes, as embedded components contained within the camera body and controlled by a microcontroller, at least a network interface device for connecting to the Internet, a transport control device for packetizing according to Internet protocols, a file transfer device for communicating with a destination user directory on the Internet, and a transmission initiating device for initiating the connection and transfer operations of the file transfer device and transport control device. The network interface device may be a modem, network adapter, or adapter for connection to the Internet. Upon capturing the digital image, the camera initiates a connection to the Internet, connects to the destination user directory, and uploads the digital images. Thereafter, the digital images are available to authorized (or any) user having access to the Internet.
