LCF-23M is a highly integrated camera module, using image JPEG compression. Through simple serial commands to control taking and obtaining images. Module was adopted the rigorous process of production, it equals to the general industrial environment, performance is very reliable.It has been widely applied to wireless image transmission, industrial image acquisition, Surveillance, monitoring, as well as civilian Surveillance and monitoring devices. Applicable to a variety of non realtime digital image acquisition occasions, such as visual doorbell, security, remote monitoring, video phone, for those application which was controled by single-chip microcomputer controlled and it needs telephone line or through GPRS, CDMA to transmit the image, LCF-23M is a great photo of the first solution.
 
Feature:
1, low-cost, low power, high-resolution images.
2, support a wide range of image resolution VGA/CIF/SIF/QCIF/160X128/80X64.
3, RS232: 1152Kbps transmit still images, preview, reached 0.75 ~ 6bps (160X128, @ 8bpS).
4, support for variable-resolution JPEG encoding different quality settings.
 
 
Application: security systems, image acquisition systems, environmental monitoring, industrial process control at the scene, medical equipment, video telephone, electricity distribution network monitoring, hydrological monitoring, oil monitoring system, the city public street lamp surveillance, railway monitoring, GPS positioning information return, urban public transport control, highway monitoring, monitoring of mine production, forestry protection monitoring, mapping exploration monitoring, intelligent area control, logistics management control, yard management monitoring, meteorological monitoring, environmental monitoring, smart instrumentation control, industrial plant automated monitoring, and alarm system.
 

Product Name:RS232 CCTV Camera

Model:LCF-23IR

A. General Description

The RS232 module is a highly integrated serial camera board that can be attached to a wireless or PDA host performing as a video camera or a JPEG compressed still camera. It provides a serial interface (RS-232) and JPEG compression engine to act as a low cost and low powered camera module for high resolution serial bus security system or PDA accessory applications.

B. Features
1. Small in size, low cost and low powered (3.3V) camera module for high resolution serial bus security system or PDA accessory applications.
2. On-board EEPROM provides a command based interface to external host via RS-232.
3. UART: 115.2Kbps for transferring JPEG still pictures or 160x128 preview  at 8bpp with 0.75fps.
4. On board OmniVision OV7640/8 VGA color sensor.
5. Built-in JPEG CODEC for different resolutions.
6. Built-in down sampling, clamping and windowing circuits for VGA, QVGA, 160x120 or 80x60 image resolutions.
7. Built-in color conversion circuits for 2-bit gray, 4-bir gray, 8-bit gray, 8-bit RGB, 12-bit RGB, 16-bit RGB or standard JPEG preview images.
8. No external DRAM required.

C. System Configuration
1. Camera Sensor
This module uses OmniVision OV7640/8 VGA color digital CameraChips with an 8-bit YCbCr interface.
2. OV528 Serial Bridge
The OV528 Serial Bridge is a JPEG CODEC embedded controller chip that can compress and transfer image data from CameraChips to external device. The OV528 takes 8-bit YCbCr 422 progressive video data from an OV7640/8 CameraChip. The camera interface synchronizes with input video data and performs down-sampling, clamping and windowing functions with desired resolution, as well as color conversion that is requested by the user through serial bus host commands.
The JPEG CODEC can achieve higher compression ratio and better image quality for various image resolutions.
3. Program EEPROM
A serial type program memory is built-in for RS232 cctv camera to provide a set of user-friendly command interfacing to external host.
