A new smartphone application lets undocumented immigrants live-stream video of contact with law enforcement, and alert family if they’re detained.

MigraCam is at least the second app designed to help those for whom an arrest could mean deportation.  

The word MigraCam is a play on Spanish slang for immigration authorities. The app sends video via text and email that can be watched live, or on delay. It can also show a person’s last known location.

If an immigrant gets detained or arrested, it can take a long time for family and friends to find out what happened, said Astrid Dominguez, director of the ACLU Border Rights Center.

“This app will allow them to know what happened at the moment of the interaction, whether it’s with local law enforcement, whether it’s with immigration authorities,” Dominguez said.

The activist group, United We Dream, has also launched a similar app called Notifica, or notify, which can send out prepared alerts by pressing a button.
