First Claim
1. A system for imaging a scene, comprisingan optical head havinga plurality of digital imaging sensors for generating image data arranged such that a first imaging sensor having a first field of view is adjacent to a second imaging sensor having a second field of view, and the first field of view of the first imaging sensor at least partially overlaps the second field of view of the second imaging sensor;
- a processor connected to the optical head and having circuitry for receiving digital image data from each digital imaging sensor, andan analog communication port for converting the digital image data into an analog data stream suitable for delivery over an analog data path.

Abstract
The systems and methods described herein provide imaging systems for imaging a scene. The imaging system includes an optical head, a processor, and an analog communication port. The processor receives captured digital image data from the optical head. The processor sends the image data to the analog communication port to generate an analog video stream that is protocol compatible with typical closed-circuit television (CCTV) networks, such as PAL or NTSC. The imaging system has a physical interface that allows the system to plug into a conventional CCTV network. To generate a video stream that is protocol compatible with the CCTV network, the analog communication port may down sample the digital image data to generate a PAL or NTSC compatible image. The down sampled digital image data is converted to a compliant analog signal and delivered over the physical layer of the CCTV network for display on a conventional television monitor.
