Pre-alarm sound 

When motion is detected, you will hear the pre-alarm sound from the camera, indicating the camera is determining the motion. The pre-alarm may last 3 seconds.

Step 1. Launch Reolink App, tap the Gear icon to go to the Device Settings page of the camera, and tap Siren under Notification settings.


Step 2. Enable Siren and Pre-Alarm Sound. Then tap Sound Test to test whether you could hear a sound from the camera.


Customize siren sound

Step 1. Enable Siren and go to Siren Sound.
You can select the Default sounds as the siren alarm. If you want to customize the sound alarm, choose Custom sounds.


Step 2. Tap the Start button to start recording your siren sound. And tap the Stop button to end the recording. The sound couldn't be longer than 5 seconds.


Step 3. Tap Apply if you are satisfied with the recording sound. 


Done! Now you could use your personal siren sound.

Set up Siren Schedule

You can set up a siren schedule for the camera to make it just ring at a certain time.

Step1. Tap Schedule and choose the Detection Type for the siren alarm.


Step2. Tap the blue bar to set a specific time in a day that you want to enable or disable the siren alarms, and you can copy the same settings to other days. Then go back to the previous page and tap Save in the top right corner to save your configurations.



  • The detection type varies from camera models.
  • One grid represents one hour.
  • For cameras Argus 2, Argus Pro, Argus Eco, and Argus 2E, you can only enable the siren, there are no settings for pre-alarm, sound test, and siren schedule.
  • Pre-alarm sound, once enabled, will be triggered as long as motion is detected, while siren will only be triggered according to the detection type you choose. Thus, it is possible that sometimes you hear the pre-alarm sound but no siren sound.
