HD-TVI / AHD interface for block cameras
SL4651
SL4651 is a small form factor analog HD-TVI/AHD video transmitter. The camera’s LVDS video input signals are demultiplexed, processed and output via an MCX coaxial connector.
Camera control is via a transparent full-duplex communication channel. The physical interface between the camera and camera control / PC is based on RS232, 3.3V CMOS (LVTTL compatible), or RS485 (optional).
Features SL4651
- =High resolution analog HD-TVI or AHD output
- =Seamlessly connects to Zoom camera blocks with industry-standard LVDS interface
- =MCX 75 ohm right angle coaxial connectors
- = CVBS loop out (if the camera supports it)
- =RS232 and 3,3V CMOS level serial camera control interface
- =RS485 camera control interface (optional)
- =Supply voltage 9V to12V DC regulated
- =RoHS and UL/UR compliant
SL4651 Video Standard
The SL4651 supports the following video standards. Note that the availability of video standards depends on the capabilities of the camera block used.
| Video standard | ||||
|---|---|---|---|---|
| 1080p | 30Hz | 25Hz | ||
| 720p | 60Hz | 50Hz |
