V4 is 3rd Eyes current version of the gateway device and the window unit camera device installed on all vehicles since 2017. This is the version all gateways and camera units installed in all our trucks currently use as the old version "V3" has been discontinued and replaced with the V4 version. For example: when we think about Apple a consumer electronics software service, they released their first iPhone in 2007. Since then, they have gone through different version of the iPhone which release every 1 to 2 years. From the first generation to the current 14th generation. The same way, our gateway has evolved over the years to the current version V4. As we continue to grow and technology continues to advance, we will see new versions in the future. 

V4 Gateway

Front View 

1. Window Unit Camera Connector: This uses a DVI cable to connect the window unit camera with the gateway. This port controls the video unit for the cameras, the Infared light on the driver facing camera, the LED indicators on the window unit, the function button on the window unit, and the communication from the gateway to the window unit. 
2. DB25 Port: This is where the 6 external 3rd Eye cameras installed on trucks are plugged. The cameras are connected by an AV cable (also known as the Octopus cable) which is plugged into the DB25 port. An easy way to remember this port is to think about it as an old school printer port. 
3. Ethernet Port: This is no longer going to be included in the new productions of the V4 gateway. It was used for online trouble shooting by our development team but the componenet has gone end of life. The jack for the Ethernet port will still be part of production but it will be covered up since it is no longer funtional. 
4. Power Cable Connector: This is where the power cable is plugged. The power cable lines contain battery power and ground, Ignition, Chassis ground, J1939 connection wires for high and low, and backup battery power wires. 
5. Backup Battery: This is the backup battery for the gateway which allows it to continue to record for about 5mins in the event the power to the gateway is lost. This typically happens when the ignition is turned off or if there was an accident. The backup camera does not power the external cameras, but the Window Unit cameras will continue to function for the life of the battery.
   

Back View 

1. USB A Type Port Connector: This is used for Tablet to Gateway (T2G) integration. It is not a cellular Phone charging port.
2.  SMA Door: This door houses important components for communication and storage of the gateway. 
   1. Sim cards: Behind the door houses the SIM cards for cellular carries. ATT is our primary cellular carrier (Identified as Sim 1 in the blue box in the image below) while T-Mobile is backup cellular carrier (Identified as Sim2 in the green box highlighted in the image below).
   2. SD Cards: These are also located behind the door. The 2 SD cards have a capacity of two 32G SD cards on factory install. we currently sell up to 128 for each side to create a capacity of 256G in total. We have tested 256G storage on each side to total 512G but not selling yet due to its ability to withstand weather conditions. 
   3. The gold connectors on the SMA door are where the antenna and the GPS connectors are screwed in. From right to left of the gold connectors is the antenna for SIM 1 (referred to as NIMO 1) the middle connector is for the GPS (It's the smaller of the three connecting wires) and the third connectors is the antenna for Sim 2 (NIMO 2). 
3. Expansion Connector: This is what we refer to as the Input/Output "IO" port. This is where the video button, event button, Input 2 and Input 3 wiring are connected.
4. HDMI Port: This can be used by our customer via viewing monitor with an HDMI cable to view all 8 cameras on their monitor. It allows them to see what the gateway has the possibility of recording. It can also be used by installers to check the cameras to make sure its properly positioned and captures the customer request. 
5. LED lights: we have 3 LED lights with their significance explained below. 
   1. Green LED Light: This signifies the battery power is connected.
   2. Red LED Light: When flashing, it means the gateway is booting. When solid, it means the gateway is connected. 
   3. Yellow LED light: When solid, it means the backup battery is charging. When its off, it means the backup battery is fully charged.
      

      

Driver Facing Camera Side

1. IR Sensor: This triggers the infra-red light around the camera when there is low light. When the Infra-red light comes on, the camera will go from colored to black and white. We see this in the events captured in the morning when its dark outside.  The infra-red light can be seen faintly as the three dotted lights in the image below highlighted in the purple box.
2. Event button. This is the green button at the bottom of the camera. When pushed, it will record a video from all the cameras to mark an event when needed. 
3. Indicator Lights. These are the lights on the camera unit that indicates some functionality signals from the gateway. 
   1. Yellow: This shows J1939/OBDII connectivity. When light is solid, it means J1939/OBDII is connected. When the light is turned off, it means J1939/OBDII is not connected. 
   2. Green: Shows GPS connection. When flashing the GPS connection has not been made yet. Solid state means GPS is connected. 
   3. Light Blue: Shows If battery is available.
   4. Orange: Shows cellular connection.  When flashing it means the system is attempting to connect to the network. Solid State means the system is connected to the network. When the light is off, it means the system is not connected to the network. 
   5. Dark Blue: This light is designated for ELD.  ELD is not activated so this light will not come on. 
   6. Red Light: As events are generated from the event button and the red button or PSV, the red light will flash once or multiple times based on the configuration. 
4. Camera Lens: This is the driver side camera that faces the driver and the cabin.
   

Front Facing Camera Side 

1. The is the mounting bracket that attaches the camera to the windshield. It is mounted by applying 2-sided adhesive tape to the mount of the camera.
2. The camera lens is the front facing camera. An infra-red light is not installed on the front side due to light reflection from the windshield. The camera makes use of the head lights to illuminate the front view when capturing image or recording a video.
