With AeroCaster Camera, the sending bit rate of video from the browser source is automatically adjusted according to the environment, but bandwidth of around 1 to 30 Mbps per unit is used according to the receiving bit rate setting in AeroCaster Switcher. Calculating the required bandwidth for the number of units used and configuring the network to enable stable communication makes it possible to use better-quality video.

Example: When the receiving bit rate is set to 5 Mbps and four AeroCaster Camera units are used, if the maximum bit rate is assumed to be this plus about 30%, an environment allowing uninterrupted transmission of 5 Mbps x 4 units x 1.3 = 32 Mbps or so to be performed is required.

To use video of stable quality, refer to the following recommendations and configure the network accordingly.

• Use a wired LAN when connection to it by the iPad or iPhone is possible.
• Use a router that supports Wi-Fi 5/6.
• Install a separate dedicated Wi-Fi router for AeroCaster.
• For the Wi-Fi frequency band, use 5 GHz and not 2.4 GHz.
• Avoid using iOS Wi-Fi tethering or a mobile router; use a stationary Wi-Fi router instead.
• Avoid using public Wi-Fi or a Wi-Fi access point to which users other than yourself are connected.
• When the Wi-Fi router and Wi-Fi access point are separated by a large distance, establish multiple Wi-Fi access points and keep the distance to the iPhone or iPad as close as possible.

< Important Notes When Transmitting Using iOS Wi-Fi Tethering >

• It is possible to send and receive video by enabling Wi-Fi tethering on the iPad and connecting the iOS device on which AeroCaster Camera is running, but when multiple AeroCaster Camera units are used (especially three or more), operation can become unstable. If this happens, set up and use separate Wi-Fi access points.
• Wi-Fi tethering generally has a shorter transmittable distance than a stationary Wi-Fi router. Use within a range of 3 to 5 meters having an unobstructed line of sight.

< Important Notes When Using Video Sent from a Browser on a Computer or Smartphone >

• In the same way as for AeroCaster Switcher, connection to the same network is necessary.
• The iPad on which AeroCaster Switcher is running and the computer or smartphone that is the transmission source must both be connected to the Internet, and HTTPS communication (port 443) with a given Internet-connected server must be possible.

< Important Notes When Connected to a Wired LAN >

• Apple Lightning to USB 3 Camera Adapter or an Apple USB-C Digital AV Multiport Adapter and Apple USB Ethernet Adapter in combination.
• To ensure definite use of the wired LAN, turn off Wi-Fi.

< If Communication Fails or Is Unstable >

• Move as close as possible to the Wi-Fi router and check whether communication is successful.
• Turn off the setting called "privacy separator" (also sometimes known as wireless isolation, AP isolation, station isolation, client isolation, or SSID isolation) that separates communication between connected devices.
• Deactivate frame aggregation (sometimes referred to as packet aggregation or TX bursting).
• If the firewall settings made on the router block TCP and UDP communication between connected devices, change the settings to allow this.

< Detailed Connection Requirements for AeroCaster Switcher and AeroCaster Camera >

• Device discovery: Multicast communication used for Bonjour (mDNS) must be mutually possible.
  → Use port 5353 and UDP, and with Bonjour, use the "_aerocaster._tcp" service.
• TCP and UDP connection to any given port on the iOS devices must be possible.
  → Because AeroCaster selects the port to use automatically with each transmission, use no port restrictions.
• Continuous communication via UDP must not be blocked or restricted.
  → Video is encoded and sent using UDP, and so uninterrupted communication between connected devices via UDP is necessary.
• A connection to the Internet must be in effect when video is sent to AeroCaster Switcher from a browser.
  → Negotiation when establishing the connection uses a server, and so an HTTPS connection to a server on the Internet is necessary.
