### **Cons**

1. **Limited Range** While effective for small areas like windows or doorways, the camera may not cover large properties or distant objects clearly.

2. **Dependence on Wi-Fi** If the camera relies on a Wi-Fi connection, poor signal strength or network outages can disrupt recording and alerts.

3. **Privacy Concerns** Continuous recording and cloud storage may raise privacy issues for neighbors or visitors, especially if the camera is placed near shared spaces.

7. **Dependence on Power Supply** Most models require a power outlet, which may limit placement options if outlets are unavailable near the monitoring area.

8. **Vulnerability to Hacking** Like all smart devices, this camera is susceptible to hacking if not properly secured with strong passwords and network encryption.
