Accessing devices remotely

The BB-1 remote device control kit can be used to control almost any equipment that is manually addressable over IP, the following examples cover some common workflows using Datavideo equipment.

Control Datavideo PTC-140 PTZ cameras using a laptop

In these examples we will access a single PTZ camera remotely via a laptop, we assume that you have two BB-1 devices that are already connected to a dv Cloud server.

WAN Mode

Let's assume the BB-1 called 'Device 1' is connected to the router and laptop in location one and the BB-1 called 'Device 2' is connected to the router at location two.

graph TD
    A["Camera Contorl"] -->|USB Ethernet| B["BB-1 Device 1"]
    B --> C["Device 1"]

    I["PTC-140"] --> J["BB-1 Device 2"]
    J --> K["Device 2"]
    K --> L["RTMP"]
    K --> M["SRT READY"]

1. At the location one, connect the first BB-1 to your internet router (using the built in Ethernet WAN port) and to the laptop (using a USB to Ethernet adapter).
2. At location two, connect the second BB-1 to your internet router (using the built in Ethernet WAN port).
3. Ensure the second BB-1 at location two is set to WAN operation mode.

1. Open a web browser and login to your dv Cloud server.

2. Select 'BB-1 Devices' from the hardware menu.

1. Click 'Shared Device IP's' to the right of 'Device 2'.
2. Datavideo DVIP devices will be automatically detected and can be selected from the drop-down menu.

1. Alternatively, if you have a third party PTZ camera you can enter the devices IP address manually. In this example we will assume the camera at location two has a local IP of 192.168.1.12. Enter the IP 192.168.1.12 as shown below.

1. Optionally give the device a friendly name such as 'Location 2 PTZ 1'.
2. Once you save the settings you will be able to access the camera from the laptop at location one by using the Remote IP (In this case 10.34.2.1).
3. Repeat steps 5 to 9 for additional cameras.

You can connect multiple control devices at site one by adding an ethernet switch.

LAN Mode

Let's assume the BB-1 called 'Device 1' is connected to the router and laptop in location one and the BB-1 called 'Device 2' is connected to the router and PTZ camera at location two.

graph LR
    A["Camera Contorl"] -->|USB Ethernet| B["BB-1 Device 1"]

    G --> J["twitch"]
    G --> K["Adobe®"]
    F --> L["RTMP"]
    F --> M["SRT READY"]

1. At location one, connect the first BB-1 to your internet router (using the built in Ethernet WAN port) and to the laptop (using a USB to Ethernet adapter).
2. At the location two, connect the second BB-1 to your internet router (using the built in Ethernet WAN port and to the PTZ camera (using a USB to Ethernet adapter). You must ensure the camera is to DHCP / automatic IP mode.
3. Ensure the second BB-1 at location two is set to LAN operation mode.

1. Open a web browser and login to your dv Cloud server.
2. Select 'BB-1 Devices' from the hardware menu.

1. Click 'Shared Device IP's' to the right of 'Device 2'.
2. You will see the PTZ camera listed in the drop-down list of connected devices, select the PTZ camera.

1. Optionally give the device a friendly name such as 'Location 2 PTZ 1'.
2. Once you save the settings you will be able to access the camera from the laptop at location one by using the Remote IP (In this case 10.34.2.1).
3. Repeat steps 5 to 9 for additional cameras.

You can connect multiple control devices at location one by adding an ethernet switch.

Using the RMC-300A controller

The procedure for using the RMC-300A controller is the same for both the LAN mode and WAN mode examples above.

The RMC-300A can simply be installed in place of the laptop used for control in the examples above, alternatively both the laptop and RMC controller can be connected by adding an ethernet switch.

1. Connect the RMC-300A to the BB-1 USB Ethernet adapter (directly or via a switch) and power it on.
2. The RMC-300A will automatically detect the Datavideo PTZ cameras that are shared via dvCloud on boot, setup and operation is the same as if the cameras were local to the controller.

If your RMC-300A is not on its factory settings, please check the following:

1. Press the 'RMC300A' tab in the top right of the touch screen.
2. Tap 'System' in the bottom right of the touch screen.
3. Network setting should show an IP address starting with 172.16.2, if it does not then tap the 'Network Setting' field and then ensure the 'DHCP' option is ON.
4. Ensure 'Auto DVIP Scan' is ON.
5. The RMC-300A will automatically detect the Datavideo PTZ cameras that are shared via dvCloud on boot, setup and operation is the same as if the cameras were local to the controller.

Using the PTZ View Assist app

The procedure for using the PTZ View Assist app on IOS or Android is the same for both the LAN mode and WAN mode examples above. You will need an Ethernet adapter for your Android or IOS device, these are readily available for almost all lightning and USB-C devices.

The IOS or Android device can simply be installed in place of the laptop used for control in the examples above, alternatively both can be connected by adding an ethernet switch.

1. Connect the IOS or Android device to the BB-1 USB Ethernet adapter (directly or via a switch) and power it on
2. Open the PTZ View Assist app
3. The app will automatically detect the Datavideo PTZ cameras that are shared via dvCloud, setup and operation is the same as if the cameras were local to the controller.

Streaming from the PTC-140

Datavideo NVD-3X MK2 Decoders

Datavideo NVD-3X MK2 HDMI/SDI decoders connect seamlessly with dvCloud using just your username and password.

Features:

• Control the NVD-30 MK2 settings from anywhere over the internet.
• Monitor the NVD-30 MK2 from anywhere over the internet.
- Easily link the NVD-30 MK2 to encoders via the cloud.
Please see the NVD-3X MK2 manual for more information.

• Use SRT (secure reliable transport) for reliable low latency point to pint links over the internet.

SRT Latency

You can add from 20 ms to 8000 ms of latency to the SRT stream. Increasing latency gives more time to buffer packets and resend any that got lost in transit to the destination. If the latency value set for the stream is too low and there is packet loss over the network, retransmission of lost packets will not be possible, and the stream quality will suffer.

dvCloud provides several detailed statistics to ensure you set an appropriate SRT latency value:

• Round Trip Time: The round-trip time between the encoder and dvCloud.
- Packet Loss %: The total percentage of packets lost between the encoder and dvCloud NOTE: Most are recovered by retransmission at the source and so do not necessarily result in any artifacts.
• Receive Rate: The total received data rate (Audio + Video).
- Total packets Received / Lost: This is the total number of SRT packets received and reported missing by the dvCloud. For each “hole” detected in the packet sequence, a request to re-transmit the lost packet is sent to the sender. This lost packet may (or may not) be re-covered by the re-transmit request. NOTE: This is the raw number of packets dropped by the network. Most are recovered by retransmission at the source and so do not necessarily result in any artifacts.
- Total packets Dropped: This is the number of SRT packets reported dropped. NOTE: These are packets that have arrived at the dvCloud too late, or that never arrive at all and have not been recovered. Some type of video artifact may result (i.e., a replayed frame or video blocking artifacts). This statistic is very important as it can indicate the SRT latency value is too low or video bitrate is too high.

As a general rule you should monitor the round trip times and set the SRT latency value to 4 * RTT or 2.5 * RTT if low latency is required, if the 'Total packets Dropped' value is increasing the latency value is still too low and must be increased.
