Use cases:

  • Connecting cameras from locations where there isn't a possibility to get a public IP address

  • Using AngelBox instead of paying for a static IP or DDNS service for connections with a dynamic public IP address

  • Making the connection to the cameras more secure

  • Bypassing firewall rules in corporate networks

  • Solving issues with changing local IP addresses of cameras

  • Avoiding configuring multiple ports when using more than one camera

  • When moving the cameras from one location to another


  • Find your cameras on the network

  • Doesn't need a public IP address

  • Doesn't need a static IP address or DDNS hostname

  • Keeps your network secure (no ports are open)

  • The communication is end-to-end encrypted

  • Keeps track of any changes within your network and adjusts itself

  • Automatic, free updates

Things to keep an eye out for especially in business network environments:

  • Make sure that the devices you plan to connect are using the default ports

  • The AngelBox will need to have an internet connection and at the same time, be on the subnet with the cameras/DVRs you want to connect

  • Some network components might block the scanning process, in that case, try connecting the AngelBox to a network switch rather than connecting it to the router directly. The same thing might happen when using business grade network components with management options as well.

  • If your firewall filters outgoing connections as well, whitelist the ports and servers listed below

  • AngelBox scans the network every 5 minutes, some old devices might not handle that well. A separate network or VLAN is recommended either for security cameras or for other devices.

  • AngelBox in its default configuration requires a DHCP server to be active in the network. It is usually handled by the router. The DHCP server doesn't have to control all the devices, you can just limit the IP range, let it assign a pre-defined IP to the AngelBox and leave all the other devices set to a static IP

  • When using AngelBox with wireless cameras, please note that this will double the bandwidth in your local network (stream is coming wirelessly from the camera, through the router to the AngelBox, then back to the router and to Angelcam)

  • With wireless cameras, be sure that the wireless network uses the same subnet with the wired devices otherwise those cameras won't be detected

  • AngelBox needs to be powered by the supplied power adapter, using adapters with lower amp ratings can result in random reboots or its inability to finish the booting process, PoE isn't supported.

  • Only the ethernet and microUSB ports are used at the moment. USB, HDMI*, audio ports are intended for possible future use only.

  • After moving the AngelBox, make sure that the SD card is correctly inserted. When in doubt, disconnect the AngelBox, remove the SD card, put it back and connect the AngelBox again

Technical specs:

  • Ports AngelBox scans:
    554, 88, 81, 555, 7447, 8554, 7070, 10554 80, 81, 8080, 8081, 8090

  • Ports used for outbound communication:
    8900, 8901

  • Servers it is connecting to:,, and all streaming servers

  • Maximum number of connected cameras: 10 cameras with 2Mbps bitrate for each stream (20Mbps of total traffic shouldn't be exceeded)

  • Avoid restarting the AngelBox within the first 5 minutes after connecting it to your network to prevent an SD card failure

Technical specs are subject to change with future AngelBox updates

*Only applies to the original AngelBox based on Raspberry Pi
