In a scenario, a doorbell camera broadcasts on which band?

• A. 5 GHz
• B. Both 2.4 and 5 GHz
• C. 2.4 GHz
• D. Neither

Answer: (C)

The main idea is that many smart home devices, like doorbell cameras, rely on the 2.4 GHz Wi‑Fi band because it travels farther and penetrates walls better. This makes a stable connection from a camera mounted at the door more reliable, even with obstacles or greater distance from the router. The 5 GHz band can offer higher data speeds but tends to have a shorter range and is more easily blocked by walls, which can make consistent connectivity harder for a doorbell camera. Some devices are dual-band, but in practical scenarios many models operate primarily on 2.4 GHz, which is why this is the best answer.
