The T4 smart video terminal is a vehicle-mounted terminal that integrates video, Android system, 7-inch display, RFID card, WiFi module, 4G network communication, and Beidou three-generation positioning, which is developed by our company. It has powerful software and hardware functions. The memory is upgraded to 2GB, the storage space is expanded to 16GB, and the APP runs smoother. It is widely used in taxis, online car-hailing, public transportation, freight and other industry applications. The main features are as follows:
- One-piece industrial structure design: suitable for tabletop installation.
- ØOperating system: Based on Android 7.1 operating system.
- Ø 7-inch touch screen: the screen resolution is 1024*600.
- ØSupport RFID, IC card driver information card.
- Ø Support external taxi peripherals such as operating status display, taxi top light, meter, flop and so on.
- ØWireless communication: Support 4G full Netcom.
- ØWIFI: Built-in WIFI hotspot, you can share the Internet.
- ØSupport up to 4 channels of video and 1 channel of camera recording.
- ØSupport VOIP voice call.
- ØIntegrate iFLYTEK voice, support Chinese and English TTS speech synthesis.
- ØSupport the installation of third-party applications and expand the application functions of the terminal industry.
- ØWith battery over-discharge protection function; with over-voltage protection, if the limit voltage is exceeded, immediately cut off the external circuit protection terminal;
- ØLow power consumption. When the flameout detects that the battery voltage is low, it can enter the zero power consumption state. At this time, the working current is less than 2mA, which can effectively protect the car battery from over-discharge.
- ØMultiple protection of power supply, which can adapt to the complex power interference environment in the car.
- Ø Provide secondary development SDK
