While no baby monitor can be guaranteed 100% hack-proof, certain features and practices can significantly enhance security. Look for baby monitors with the following characteristics: Encrypted Signal: Ensure the monitor uses strong encryption standards (e.g., AES-256) to protect the data transmitted between the camera and the monitor. Two-Factor Authentication (2FA): Choose monitors that support 2FA for an added layer of security when accessing the monitor via apps. Closed Systems: Non-Wi-Fi monitors that use radio frequency (RF) for transmission (like DECT technology) are less susceptible to hacking compared to Wi-Fi monitors, as they do not connect to the internet. Regular Firmware Updates: Opt for monitors from reputable manufacturers that provide regular firmware updates to address security vulnerabilities. Password Protection: Use strong, unique passwords for the monitor and any associated accounts.
