OSD video character overlay performance parameters and applications

OSD video character overlay can choose traditional BIG5 encoding font, the default national standard 2312 simplified font, can overlay traditional characters and customize any language font. This is our company's independent research and development, production and sales, quality assurance, low price, the appearance of this product greatly reduces the user's cost of use, OSD video character overlay users do not need to understand the knowledge of video overlay, only need to know the serial communication Do video overlays. OSD video character overlay is a general-purpose device dedicated to video overlay. It can work in internal mode (module generates video signal, can generate color background, color text) and external mode (white text, superimpose external video, can draw black border). In this mode, the communication interface RS232, SPI, TWI, onboard real time clock, date and time can be set independently whether to display, location color size, etc. Item No .: OM9024 Specifications: Set weight: 100 grams.

OSD video character overlay performance parameters:

Input voltage: 7 ï½ž 9V (with voltage regulator on board), optional 5V
Communication interface: RS23, TWI, SPI, RS485 (optional)
Input level: CMOS / TTL / 485
Video impedance: 75 ohms Working temperature: -40 â„ƒ ï½ž + 85 â„ƒ (industrial grade)

OSD video character overlay product features:

Careful hardware design, stable and reliable display, clear image based on the powerful MB90092 character superposition chip design, can overlay text, pictures, animation
GB2312 font, no character limit, wider application
RS232 (TTL and CMOS level optional), TWI, SPI, RS485 (special instructions required)
Onboard RTC real time clock, practice and date can be independently set to display location color and size. Internal mode and external mode are optional. Video can be generated without inputting video. Users do not need to initialize. Standard video socket and industrial wiring terminal are used immediately after power-on. Convenient for free secondary computer (VB) secondary development source code, free RS232, SPI, TWI lower computer test code command format is simple, with communication control function expansion function control pin

OSD video character overlay application areas:
Video monitoring, security industry, elevator floor display, road and bridge monitoring, toll station, bank note monitoring, queuing system, large electronic display screen, temperature, humidity, time character overlay, industrial control site
GPS information overlay mobile video ads, etc.

The LED exit sign light is specially made from aluminum and acrylic materials, and is also fast dissipating heat, insulating and corrosion resistant. LED emergency lights are illuminated with super bright LEDs to ensure visibility in dark corridors and hallways. In case of an emergency power outage, the exit lane will be illuminated. Exit signs are designed for various types of indoor commercial uses such as hotels, shopping centers, theaters, restaurants and other public places. Any emergency exit signs must have continued reliability. Easy to install and can be hung on the wall or from the ceiling.
