Range: The 2.4 GHz band offers a longer range, meaning it can cover larger areas and penetrate solid objects like walls more effectively than 5 GHz.

Speed: Generally, 2.4 GHz provides slower speeds compared to 5 GHz due to a lower maximum data rate.

Interference: More prone to interference since many other devices (like cordless phones, microwaves, and Bluetooth devices) operate on the 2.4 GHz frequency, leading to potential congestion and slower network performance.

Range: Offers a shorter range compared to 2.4 GHz and may have difficulty penetrating walls and other obstacles.

Speed: Typically provides faster speeds and higher data rates due to more available bandwidth.

Interference: Less prone to interference as fewer devices operate on this frequency, leading to a more stable connection.

Ethernet is a widely used technology for wired networking, providing a stable and high-speed connection between devices on a local area network (LAN).

Speed: Ethernet can offer higher and more consistent speeds compared to Wi-Fi. Modern Ethernet standards can support speeds from 100 Mbps (Fast Ethernet) to 10 Gbps (10 Gigabit Ethernet) and beyond.

Stability and Reliability: Because it uses a wired connection, Ethernet is less susceptible to interference from other devices and physical barriers, leading to a more stable and reliable connection.

Lower Latency: Ethernet typically offers lower latency compared to Wi-Fi, making it ideal for applications that require real-time data transfer, such as online gaming and video conferencing.

Security: A wired connection is generally more secure than a wireless one, as physical access to the network is required to intercept data.

4G is the fourth generation of mobile network technology, offering significant improvements over its predecessor, 3G.

Speed: Offers download speeds ranging from 5 Mbps to 50 Mbps and even higher in optimal conditions. This allows for smooth streaming of high-definition videos, fast downloads, and responsive web browsing.

Latency: Reduced latency compared to 3G, improving real-time applications such as online gaming and video conferencing.

Capacity: Supports a higher number of simultaneous connections, making it more suitable for densely populated areas.

Coverage: Widespread availability, with extensive networks in urban and many rural areas.

Matter is a unified, open-source connectivity protocol designed to standardize and simplify communication between smart home devices from different manufacturers. Developed by the Connectivity Standards Alliance (formerly the Zigbee Alliance), Matter aims to improve interoperability, security, and reliability across various smart home ecosystems.

Cameras were left out of the standard until Matter 1.5, published in November 2025, which added camera device types with live video and audio streaming over WebRTC, two-way talk, motion detection, event history and pan-tilt-zoom control. Before that release a camera could only reach a Matter ecosystem through its hub side, bridging the accessories paired to it, never its own video feed.

Because the camera device types are this recent, support arrives model by model and often through a firmware update, so a camera that works with Apple Home, Alexa or Google Home today is not necessarily a Matter device.
