How to Setup Audio Detection with Your Security Camera System | 3G Mobile CCTV
Audio Detection is a feature that can be a very reliable way to capture a conversation or other important sounds that need to be recorded. It allows a security camera with a built-in microphone or audio input to trigger recording when sound is detected. You no longer have to rely on video-based motion detection to try and capture audio of an event and missing out on everything that was said. With audio detection you can even capture video/audio when persons are conversing outside the camera's field of view, but near enough to activate audio detection. You can finely adjust the sensitivity and threshold settings to decrease your storage needs. In this guide, we show you how to setup and use audio detection with surveillance cameras purchased from CCTV Camera World.
With Audio Detection you can set up alerts and triggers like you would for traditional video detection. Email, buzzer, and alarm upload features are all supported when an audio event is detected allowing you to be notified immediately. This can save you a lot of time of having to sift through hours of continuous audio/video looking for a small segment of conversation or sound.
What do you need for Audio Detection to work?
An IP security camera with built-in microphone
Or an IP camera with audio input for a security camera microphone (microphone not included)
A compatible NVR system that supports audio detection
How is the Audio Detection setup?
1. Mount The Camera or Microphone to Capture Good Sound and Picture
It is important that you mount the camera strategically to capture good video and audio. This includes making sure that the camera or microphone is not near constant background noise that will trigger audio detection and create false alerts. Conversely ensure that the audio device is close enough to capture the desired recording. Keep in mind that sensitivity settings can be adjusted and fine tuned for most applications. Mount the camera pointed in a direction and angle where the sound will be coming from to avoid missing out on important footage.
2. Enable Audio Detection on The NVR
Navigate by right clicking and then using the Main Menu button
Login to the DVR using the graphical password or username and password
Go to the Setting section on the bottom row and click Event
On the left-hand side click the Audio Detect tab
To enable Audio Detection to make sure you tick the checkbox labeled Intensity Change and click apply
The Enable Input Abnormality option is meant to detect when audio has stopped working or been compromised by vandalism.
3. Finely Adjust Your Audio Detection Settings
Under the Intensity Change text box you will find there are two bars for adjustment:
Sensitivity
It is important to change as this setting will increase or decrease the amount of sound required to trigger an event
Threshold
This setting should be left alone unless you find it producing too many false alerts or no alerts at all. It greatly modifies the settings and can be difficult to adjust.
4. Select The Event Trigger Settings According To Your Needs
After you have your camera and recorder detecting the audio it’s important to make sure you set up the proper schedule and events to trigger after audio is detected.
Open the Period setting to set the schedule for the camera to detect audio
Record Channel can be selected if you want to record video for that channel, or additional channels you have connected to your recorder
Post record is the amount of time to record after the audio event has ended
Alarm out provides an option to sound an optional alarm that is connected to the recorder if the NVR supports it
Latch is not pertinent to audio detection
Snapshot allows you to capture a snapshot of the scene in the video
Other features include Push notifications, Email, or Buzzer that are useful for alerting yourself if you would like.
