1. Limited Connectivity: The WGEC Y21-78 intrusion alarm system does not offer Wi-Fi connectivity, meaning you cannot monitor or control the system remotely.

2. No Cellular Backup: The device does not have a cellular backup option, so if the phone line is cut or the power goes out, the system will be unable to send alerts.

3. No Integration with Other Smart Home Devices: The WGEC Y21-78 intrusion alarm system does not integrate with other smart home devices or platforms, limiting its compatibility with other home automation systems.

However, its lack of Wi-Fi connectivity, cellular backup, integration with other smart home devices, and voice control may be drawbacks for some users.

If you require a standalone intrusion alarm system with advanced features and easy installation, the WGEC Y21-78 intrusion alarm system is an excellent choice.
