Opus LF vs Great Security Alert

Opus LF is a personal alarm in your mobile phone. With Opus LF you can easily alert pre-selected receivers who can watch the emergency situation via real time video streaming and follow your location in order to speed response. The app requires login information for use. If you have forgotten your information, we recommend that you contact the Opus LF responsible person to retrieve your information. Continued use of GPS running in the background can dramatically decrease battery life.

On the contrary to most other applications that send alarm to friends, Great Security Alert normally sends the alarm to a response centre. The connection to the response centre goes through the Skyresponse system. Please contact Skyresponse to get a full list of professional response centers that support Great Security products. To be able to use Great Security, the user needs to have an account on Great Security server where the user has added their profile and the instructions that should be performed when an alarm is triggered.
