Image Capture and Quality

Image Sensors

The camera has four '2 megapixel CMOS (Complementary Metal-Oxide Semiconductor) image sensors', effectively offering 8 megapixel functionality. The Bayer Mosaic RGB filter arranges the red, green, and blue color filters on a square 'photosensor grid', each 2 x 2 unit on the grid comprising two green, one blue, and one red filter. This ensures clear pictures with proper color differentiation.

Resolution

Each image sensor offers a resolution of 1600(H) x 1200(V) pixels, taking the total resolution to 6400(H) x 1200(V) - which means the AV8185 is a comfortable substitute for up to 24 analog cameras. The resolution windows down to a 32x32 pixels window.

Operation/Frame Rate

The camera supports video frame rates up to 88 fps at 800x600, 22 fps at 1600x1200, and 5.5 fps at 6400x1200. It is also capable of sustaining over 80 billion operations per second.

Progressive Scan

The camera offers a full motion progressive scan of 1600 x 1200 video at 22 fps.

180° Panoramic View

The AV8185 Camera has a 180° panoramic field of view. The high-definition imaging eliminates the need for any de-warping software.

Low Light Functionality

The 1/2-inch CMOS sensor enables the camera to function in light conditions as low as 0.2 Lux at F2.0. In excessive darkness, the proprietary Moonlight Mode feature can be activated. In this mode, the shutter speed is modified for extended exposure, hence more light is captured. Noise Cancellation prevents 'visual noise' which is a common problem during image capture with long shutter speeds. Programmable motion blurring further improves image quality in low light.

Forensic Zooming

Forensic zooming (the camera can be a replacement for other PTZ devices) can zoom either live recordings or 'after event' video when recording the full field of view in HD. This is useful when CCTV video footage needs to be previewed and analyzed in situations such as in criminal and other legal cases.

Simultaneous Panoramic and PTZ View

To set monitoring priorities for sensitive areas, the AV8185 can be programmed for simultaneous panoramic and digital PTZ viewing for up to four regions of interest.

Backlight Compensation

Backlight compensation adjusts video gain to correct the exposure when the object is in front of a bright light source.

White Balance

The auto multi-matrix white balance feature adjusts the red, green, and blue colors taking a standard white reference to deliver clear images.

Flicker Control

The camera has a 50/60Hz selectable flicker control that ensures seamless viewing of moving images.

Image Rotation

The image can be electronically rotated as and when needed.

Image Cropping

The image can be cropped to eliminate unnecessary portions.

Alarms

Motion Detection

The AV8185 IP Camera's motion detection feature compares the current frame with a pre-determined frame to accurately trigger an alarm if motion is detected. Up to 64 motion detection zones can be specified.

Networking, Data Transmission, and Image Storage

H.264 (MPEG4, Part 10) Compression Standard / Bit Rate Control

When capturing, storing, or transmitting images, the AV8185 simultaneously supports both H.264 and MJPEG compression standards, enabling 10 times less bandwidth and storage utilization than average MJPEG standards. The camera supports 21 levels of quality. The bit rate control feature helps maintain the required bandwidth and storage size.

RTSP (Real Time Streaming Protocol)

This streaming protocol enables video from the AV8185 to be viewed on media players such as Windows Media Player, VLC Player, and Apple QuickTime.

Image Transmission Protocols

The AV8185 has a 100Base-T Ethernet Network Interface and supports TFTP, HTTP, RTSP, RTP/TCP, and RTP/UDP image transmission protocols. It provides multi-streaming with 8 non-identical streams.

Power Supply

PoE (Power over Ethernet)

The Power over Ethernet feature enables power to be supplied from the network itself. Thus, there is no requirement for extra wiring and power outlets

Auxiliary Power Supply

The AV8185 can also be powered by a 12-48 VDC and 24VAC power supply.

Power Consumption

The camera unit consumes a maximum power of 9 watts.

Certifications and Regulatory Approvals

Standardized Compliance

The AV8185 IP Camera is FCC, CE, and RoHS compliant.
