Why Your Security Camera Gateway Needs a Speed Test
Your home security cameras are only as good as the network connection behind them. If your camera gateway — the hub that connects your cameras to the internet — doesn't have enough bandwidth, you'll get choppy video, delayed alerts, and gaps in your recordings. Running a speed test on your gateway helps you find and fix these problems before they cost you missed footage.
Most people test their main internet connection but forget about the device that actually handles their camera traffic. Let's fix that.
What Is a Security Camera Gateway?
A security camera gateway is the device that sits between your cameras and your internet connection. Some popular examples include the Ring Base Station, Arlo SmartHub, Google Nest Wi-Fi point, and Eufy HomeBase. It collects video feeds from your cameras and sends them to the cloud or your phone.
How It Differs from Your Router
Your router handles all internet traffic for your entire home — streaming, gaming, browsing, everything. The camera gateway only manages camera data. But it still depends on your router for internet access. If either device has a bottleneck, your cameras suffer.
Think of it like a highway. Your router is the main road. Your camera gateway is an on-ramp. If the on-ramp is jammed or the highway is full, your camera footage gets stuck either way.
How Much Bandwidth Do Your Cameras Actually Need?
Before you run a test, you need to know what speeds to aim for. Each camera uses a specific amount of upload bandwidth to send video to the cloud. Upload speed matters more than download here because your cameras are sending data out, not pulling it in. Check out our guide on what counts as a good upload speed for more detail.
| Camera Resolution | Upload per Camera | 4 Cameras Total | 8 Cameras Total |
|---|---|---|---|
| 720p HD | 1–1.5 Mbps | 4–6 Mbps | 8–12 Mbps |
| 1080p Full HD | 2–3 Mbps | 8–12 Mbps | 16–24 Mbps |
| 2K QHD | 3–5 Mbps | 12–20 Mbps | 24–40 Mbps |
| 4K Ultra HD | 6–10 Mbps | 24–40 Mbps | 48–80 Mbps |
These numbers assume continuous recording. If your cameras only record on motion detection, you'll use less bandwidth on average — but you still need the full amount available during peak moments when multiple cameras trigger at once.
Step-by-Step: Running a Speed Test on Your Gateway
You can't plug a keyboard into your camera gateway and open a browser. So you need to test the connection indirectly. Here are three methods, from easiest to most accurate.
Method 1: Test from a Device on the Same Network Segment
This is the quickest approach. Connect a laptop or phone to the same Wi-Fi network or Ethernet switch your gateway uses. Then run a speed test from that device. The results will closely reflect what your gateway experiences.
- Find out if your gateway is on Wi-Fi or Ethernet. Check the gateway's app or manual.
- If it's on Ethernet, plug your laptop into the same switch or router port group.
- If it's on Wi-Fi, stand right next to the gateway with your phone and connect to the same network band (2.4 GHz or 5 GHz).
- Run the test and note your upload speed, download speed, and ping.
- Run it 3 times at different times of day for a realistic picture.
Method 2: Use Your Gateway's Built-In Diagnostics
Some gateways have network diagnostics in their companion app. Arlo's app, for example, shows connection quality for each camera and the base station. Google Home shows real-time bandwidth usage. Check your app's settings or device health section for these tools.
Method 3: Check from Your Router's Admin Panel
Many modern routers show per-device bandwidth usage. Log into your router (usually at 192.168.1.1 or 192.168.0.1) and look for a "connected devices" or "traffic monitor" page. Find your gateway by name or MAC address, and check how much bandwidth it's actually using versus what's available.
What to Look for in Your Results
Once you have your speed test numbers, here's how to read them for camera performance.
Upload Speed Is King
Your upload speed needs to be at least 25% higher than your cameras' total requirement. So if you have four 1080p cameras needing 12 Mbps total, you want at least 15 Mbps upload at the gateway. This headroom prevents buffering when all cameras activate simultaneously.
Ping and Latency Matter Too
High latency — the delay between your camera recording something and the cloud receiving it — means slow alerts on your phone. You want ping under 50 ms for responsive notifications. If your ping is above 100 ms, you might get motion alerts 5–10 seconds late. Learn more about what latency is and why it matters.
Watch for Packet Loss
Packet loss is when small chunks of data disappear between your gateway and the internet. Even 1–2% packet loss can cause pixelated video, frozen frames, and dropped recordings. If you suspect this is happening, run a packet loss test to confirm.
How to Fix Slow Gateway Speeds
If your test reveals problems, here are targeted fixes ranked by impact.
Switch from Wi-Fi to Ethernet
This single change can double or triple your gateway's effective bandwidth. Wi-Fi is convenient, but it's shared with every other device in your home and degrades with distance. A direct Ethernet cable to your router gives your gateway a dedicated, stable connection. If running cable is hard, try a powerline Ethernet adapter — they typically deliver 50–150 Mbps through your home's electrical wiring.
Move the Gateway Closer to the Router
If Ethernet isn't an option, reduce the distance between your gateway and router. Every wall and floor between them cuts your Wi-Fi signal. At 30 feet with two walls in between, a 5 GHz Wi-Fi signal can drop from 400 Mbps to under 80 Mbps.
Reduce Competition on Your Network
If your upload speed is limited — say you're on a cable plan with only 10 Mbps upload — other devices uploading large files, running video calls, or backing up to the cloud will eat into your camera bandwidth. Use your router's Quality of Service (QoS) settings to prioritize traffic from your camera gateway. Most routers let you set this by device or by traffic type.
Upgrade Your Internet Plan
If you have 6 or more cameras recording in 1080p or higher, you need real upload bandwidth. Many cable internet plans only offer 5–10 Mbps upload, which isn't enough. Fiber plans typically offer 100 Mbps or more in both directions. Check our cable vs. fiber comparison to see which makes sense for your setup.
Lower Camera Resolution as a Last Resort
If you can't upgrade your internet or fix the connection, dropping from 2K to 1080p per camera cuts bandwidth needs by about 40%. You'll still get clear enough footage to identify faces and license plates within 20–30 feet.
How Often Should You Test?
Don't just test once and forget about it. Run a speed test on your gateway setup at least once a month. Also test after any of these events:
- Adding a new camera to your system
- Changing your internet plan
- Moving your gateway or router
- Noticing choppy playback or delayed notifications
- After a firmware update on your gateway or router
Keep a simple log of your results. If speeds gradually decline over weeks, you'll catch the trend early instead of wondering why your cameras stopped working reliably.
Quick Summary
Your security cameras depend on a fast, stable connection through your gateway. Test the speed by connecting a device to the same network segment and running a speed test. Focus on upload speed — you need at least 2–3 Mbps per 1080p camera with 25% headroom. Keep ping under 50 ms and packet loss at 0%. If speeds are low, switch to Ethernet, move the gateway closer to your router, set up QoS, or consider a fiber upgrade. Test monthly to catch problems before they leave gaps in your security footage.
