    Being open source, Haven allows for transparency and community involvement in its development, which can lead to more secure and reliable software.
  • Integration with Other Security Tools
    Haven can be integrated with other security tools like Signal, enabling encrypted notifications about possible intrusions.
  • Sensor Utilization
    The app makes innovative use of a smartphone's existing sensors, such as the camera, microphone, and accelerometer, to monitor and detect unusual activity.
  • Cost-Effective Solution
    Haven provides a cost-effective way to set up a basic surveillance system without needing to purchase additional hardware.

Possible disadvantages

  • Limited to Smartphone Capabilities
    Haven is restricted by the sensors and processing power of the smartphone it runs on, which might limit its effectiveness in certain scenarios.
  • Complex Setup
    Users may find the initial setup and configuration of the app to be complex, especially those not familiar with configuring security-focused software.
  • Potential for False Alarms
    Due to its sensitivity to sensor input, Haven might generate false alarms, causing notifications for non-threatening situations.
  • Device Dependency
    Since the app requires a dedicated device to function effectively, it might not be practical for users who do not have an old or spare smartphone.
  • High Battery Usage
    Continuous monitoring using multiple sensors can lead to high battery consumption, potentially requiring more frequent charging of the device.
