Although most security cameras operate in the 2.4 GHz frequency band, some security cameras work with 5 GHz Wi-Fi networks.
This gives users faster data transmission, smoother live video streaming, and higher-resolution security footage. Dual Band support switches between 2.4 GHz vs 5 GHz as needed if the Wi-Fi network supports both.
Below, we address all of your biggest queries and concerns about Wi-Fi networks and security cameras.
Do Security Cameras Work with 5 GHz Wi-Fi?
Yes, some security cameras work with 5 GHz Wi-Fi, provided they operate on a 5 GHz frequency band or have dual-band capabilities.
Only 5 GHz security cameras and those with dual-band (2.4 GHz and 5 GHz) features work seamlessly with 5 GHz Wi-Fi networks.
Many wireless internet router brands are moving towards 5 GHz technology while others (i.e., Tenda, TP-Link, and Asus) are opting for dual-band capabilities. Check out our article Do I Need a Router for My Security Camera to learn more about Wi-Fi routers and how to choose the best one.
What’s the Difference Between 2.4 GHz vs 5GHz for Security Cameras?
Not all security cameras work with 5 GHz Wi-Fi. What’s the difference between 2.4GHz vs 5GHz?
2.4 GHz Security Camera
| Pros | Cons |
| · More extensive range for better coverage · Penetrates solid objects | · Slow data transmission rate · Prone to signal interference |
A 2.4 GHz system uses low-frequency radio waves, so it travels longer distances than 5 GHz and better penetrates solid objects, including walls.
It’s commonly used in microwave ovens, baby monitors, garage door openers, and radio-controlled toys.
Because of this, interference with 2.4 GHz wireless security cameras is common. But a 2.4 GHz system is perfect if the wireless security camera is far from the Wi-Fi router.
5 GHz Security Camera
| Pros | Cons |
| · Fast data transmission rate · Less prone to signal interferences | · Limited range · Poor penetration of obstacles |
5 GHz systems are very fast thanks to the latest wireless internet protocols.
Introduced around the millennium, fewer devices use the band, meaning there’s less competition for the signal.
A 5 GHz wireless security camera is great if the network is nearby and there aren’t many obstacles between them.
Does 5 GHz penetrate walls better than 2.4 GHz?
2.4 GHz Wi-Fi signals penetrate walls better than 5 GHz signals. However, a 5 GHz system negates signal interference better than a 2.4 GHz system.
Why Do Security Cameras Use 2.4 GHz?
Security cameras use a 2.4 GHz bandwidth because of installation flexibility.
It allows homeowners and businesses to set up their security systems far away from the router, even with obstacles between the two devices’ lines of sight.
Why is 2.4 GHz so common?
The 2.4 GHz frequency band is so common because it’s much older than 5GHz. It first emerged in the 1970s, and is used in microwave ovens, garage door openers, car alarms, baby monitors, and microphones.
Are All Wi-Fi Security Cameras on 2.4 GHz?
Wi-Fi security cameras are usually on 2.4 GHz, but not always. Some operate on both 2.4 GHz and 5 GHz frequency bands.
A 2.4 GHz security camera will not work on a 5 GHz wireless network because of frequency incompatibility. To work on both networks, the security camera requires dual band technology.
What security cameras work with 5 GHz Wi-Fi?
A growing number of security cameras now use 5 GHz, including:
· Reolink E1 Pro
· Ring Floodlight Cam Wired Pro
· Arlo Ultra 2- Foscam HT2.
Discover which 5 GHz wireless security camera is right for you.
Conclusion
Some security cameras work with 5 GHz Wi-Fi, but most are still 2.4 GHz.
They might be somewhat outdated, but 2.4 GHz systems are still useful in many situations, like larger homes.
For smaller spaces, 5 GHz Wi-Fi provides faster and more stable security camera streaming.
