The main difference between wireless and wired surveillance lies in the method of data transmission. Wired surveillance systems employ transmission cables (such as Ethernet cables) to transmit video and audio signals from the cameras to the main host. Because wired surveillance doesn't rely on the stability of wireless signals for data transmission, it offers a more stable data transfer with less susceptibility to interference and signal loss, making it a more reliable choice. Additionally, wired surveillance cameras are more easily powered without the need for extra batteries or charging devices.

Wireless surveillance, on the other hand, uses electromagnetic wave signals to transmit data, which can be received by devices like receivers or routers within a certain range. Wireless surveillance often utilizes Wi-Fi or other wireless LAN technologies, allowing users to view surveillance footage remotely over the internet. The advantage of wireless surveillance lies in its flexibility since cameras don't need physical cable connections, making it easier to place cameras in desired monitoring locations. However, the drawback is that wireless signals are more susceptible to interference and loss, and battery life must be ensured to prevent power outage.

In summary, wired surveillance systems are relatively more reliable and easier to install, but they require wiring. Wireless surveillance offers installation flexibility but demands consideration of issues like signal interference and signal loss. The choice between the two should be based on specific needs and the environment.

When considering indoor/outdoor home security, both wired and wireless cameras, including light bulb cameras, offer different advantages, so the choice should align with your particular requirements.
