Although most security cameras operate in the 2.4 GHz frequency band, some security cameras work with 5 GHz Wi-Fi networks, empowering homeowners to enjoy faster data transmission, smoother live video streaming, and higher-resolution security footage.
Advances in Wi-Fi router and security camera technologies encourage a move towards the latest generation of network bands, and many routers feature dual band support (both 2.4 and 5 GHz).
Do Security Cameras Work with 5 GHz Wi-Fi?
Yes, some security cameras work with 5 GHz Wi-Fi, provided they operate on a similar frequency band or have dual-band capabilities.
Only 5 GHz security cameras and those with dual-band (2.4 GHz and 5 GHz) features will work seamlessly with 5 GHz Wi-Fi. Users can derive great benefits from such systems, like less signal interference, faster download and upload speeds, and smoother video streaming.
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.
2.4 GHz vs. 5 GHz for Security Cameras: Will It Make a Difference?
It’s a fact that not all security cameras work with 5 GHz Wi-Fi. So, is it worth investing in a 5 GHz security camera, or should sticking to 2.4 GHz technology? The answer to this question lies in the difference between 2.4 GHz vs. 5 GHz.
2.4 GHz
| Pros | Cons |
| More extensive range for better coveragePenetrates solid objects | Slow data transmission rateProne to signal interferences |
A 2.4 GHz system uses low-frequency radio waves, allowing it to travel longer distances and penetrate solid objects, including walls and trees. It’s a technology that dates back to the ‘80s and is commonly used in microwave ovens, baby monitors, garage door openers, and radio-controlled toys.
Because all these household objects operate on the same band, they can easily interfere with the wireless signal going to and from a security camera, slowing down data transmission. Although a 2.4 GHz band has 14 channels (the Wi-Fi router can automatically select the least congested channel to connect to), multiple devices using it will still reduce signal stability.
Nevertheless, a 2.4 GHz system is perfect if the wireless security camera is far from the Wi-Fi router, or when there are many obstructions between them.
5 GHz
| Pros | Cons |
| Fast data transmission rateLess prone to signal interferences | Limited range, except for the 802.11ac wireless protocolPoor penetration of obstacles |
If 2.4 GHz technology works at a snail’s pace, a 5 GHz system is lightning-fast. This technology uses the latest wireless internet protocols, including 802.11ax (2.4 Gbps), 802.11ac wave 2 (1.73 Gbps), 802.11ac wave 1 (866.7 Mbps), and 802.11n (450 Mbps).
Introduced around the millennium, fewer household devices use the band, meaning there’s less competition for the signal.
The 2.4 GHz system’s strengths are the 5 GHz technology’s Achilles heel—namely, poor penetration through solid objects and limited range. Still, a 5 GHz Wi-Fi router is perfect if the security camera is nearby and there aren’t many obstacles between them.
2.4 GHz vs. 5 GHz: Which to Choose?
Deciding between a 2.4 GHz and 5 GHz system boils down to four crucial factors.
1. Home Size
A 2.4 GHz system is better suited for large homes and buildings because of its better coverage. On the other hand, 5 GHz technology is more suitable in smaller spaces.
2. Obstacles
Pick a 5 GHz technology if there are no obstacles between the router and internet-connected devices. Otherwise, a 2.4 GHz system is more suitable.
3. Interferences
Families with many devices running on the 2.4 GHz bandwidth should pick a 5 GHz system or dual band router to reduce signal interference.
4. Device Type
A 2.4 GHz security camera only works with a 2.4 GHz system. On the other hand, a 5GHz security camera only works with a 5 GHz network. A dual band wireless outdoor security camera can do that, too.
The Evolution from 2.4 GHz to 5 GHz
The 2.4 GHz system originated in the Hawaiian Islands in 1971, when ALOHANnet connected locals using a UHF wireless packet network. By 1985, the FCC released the ISM band for the general public.
In 1997, the Institute of Electrical and Electronics Engineers released the first wireless internet protocol, 802.11, with 2 Mbps. Two years later, the 802.11b protocol saw action with an 11 Mbps speed. The 802.11g protocol improved the data speeds to 22 Mbps in 2003.
The IEEE introduced the 802.11a standard to leverage the 5 GHz bandwidth because too many devices operate on the 2.4 GHz frequency. Newer internet protocols now use the 5 GHz bandwidth while maintaining compatibility with 2.4 GHz systems.
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 farther away from the router, even with obstacles between the two devices’ lines of sight.
Are All Wi-Fi Security Cameras on 2.4 GHz?
No, Wi-Fi security cameras operate on both 2.4 GHz and 5 GHz frequency bands, with the latter being a newer technology requiring the latest wireless internet protocols.
Will a 2.4 GHz Security Camera Work for 5 GHz?
No, a 2.4 GHz security camera will not work on a 5 GHz wireless network because of frequency incompatibility.
Future wireless protocols and technology upgrades dictate a move towards 5 GHz systems. However, 2.4 GHz technologies will remain relevant.
Homeowners and businesses can only expect more interoperability between the two systems, or they can look forward to sixth-generation wireless technology that can potentially address the shortcomings of 2G and 5G systems.
