You're staring at your phone, trying to check the front door or see if the dog is eating the couch, and there it is. Code -45. It’s annoying. Honestly, it's one of those errors that makes you want to toss the whole Roku Smart Home system out the window. You’ve got the Roku Indoor Camera or the Outdoor SE, and suddenly, the stream just dies.
The dreaded code -45 basically means your camera has lost its handshake with the Roku servers. It's a timeout. A digital "I give up."
Most people think their Wi-Fi is broken, but that's not always the case. Sometimes it's the firmware. Sometimes it's just a weird quirk of the 2.4GHz band. If you’ve been seeing this error, you aren't alone—hundreds of users on the Roku Community forums have been venting about this exact handshake failure for months.
What is Code -45 on a Roku Camera Anyway?
Technically, a code -45 is a "Connection Timeout."
Think of it like this: your camera is trying to send a video packet to the cloud so you can see it on your app. The cloud waits for a second, doesn't hear anything, and shuts the door. When the app realizes the door is shut, it throws the -45 error. It's different from code -90 (which usually means the camera is totally offline/unpowered) because code -45 suggests the camera knows it should be working, but the data stream is getting interrupted or choked out.
The reality is that these cameras are rebranded Wyze hardware running Roku-specific firmware. Because of that, they inherit some of the classic IoT (Internet of Things) connectivity gremlins.

If your signal strength is low, you’ll see it. If your router is juggling too many devices, you’ll see it. If Roku’s AWS servers are having a bad Tuesday? Yeah, you’ll see it then too.
The First Thing You Should Check (And No, It's Not the Power)
Before you go climbing a ladder to reset the thing, check your upload speed. Most people focus on download speeds because that’s what Netflix needs. But cameras? They live and die by upload.
If you have a dozen smart devices and a video doorbell all trying to "talk" at once, your 5Mbps upload speed is going to buckle. Code -45 often triggers when the camera can't maintain a consistent 1-2Mbps upload stream.
Open a speed test app on your phone while standing right next to the camera. If your upload is hovering near 1 or 2 Mbps, you found your culprit.
The 2.4GHz Crowding Issue
Roku cameras only support 2.4GHz Wi-Fi. That’s the old, slow lane of the internet. It travels through walls better than 5GHz, which is why they use it, but it’s incredibly prone to interference.
Your neighbor's router, your microwave, and even some old baby monitors can scream over the 2.4GHz frequency. When that interference happens, the camera drops packets. Too many dropped packets equals a code -45.
Try changing your router's channel. Most routers are set to "Auto," which is usually "Wrong." Switch it manually to channel 1, 6, or 11. These are the only non-overlapping channels. It sounds like tech-wizardry, but it’s basically just moving your car to a lane with less traffic.
Power Cycling: The "Smart" Way
We all know the "unplug it and plug it back in" trick. But with code -45, there’s a specific order that seems to work better for Roku's ecosystem.
- Close the Roku Smart Home app completely. Don't just swipe away; force stop it.
- Unplug the camera from its power source.
- Wait at least 30 seconds. This lets the capacitors fully discharge.
- Plug the camera back in and wait for the solid status light.
- Only then, open the app.
Why this way? Because the app often caches the "error state." If you reboot the camera but the app still thinks it's disconnected, it might keep throwing that code -45 out of habit.

Firmware Glitches and the Roku App Update
Sometimes the problem isn't your house at all. It's the code.
Roku pushes updates to these cameras fairly often. If your camera is on an older version of the firmware but your app updated to the latest version, they might stop speaking the same language.
Check the "Device Info" in your app settings. If there’s an update pending, run it. If the update fails (which happens more than it should), you might have to delete the camera from your account and re-add it as if it were brand new. It’s a pain. It takes five minutes. But it usually clears the cache that causes code -45.
Advanced Fixes for Stubborn Cameras
If you’ve done the basics and it’s still acting up, it’s time to look at your router's firewall or "Smart Connect" features.
Many modern mesh systems (like Eero or Orbi) use a single name for both 2.4GHz and 5GHz. This is great for phones, but it's a nightmare for Roku cameras. The camera gets confused and tries to connect to the 5GHz side, fails, and—you guessed it—code -45.
If your router allows it, create a "Guest Network" that is strictly 2.4GHz. Connect your Roku cameras to that. It keeps them in their own lane and prevents the router from trying to "steer" them to a frequency they can't handle.
Also, check for a "WPA3" setting. These cameras prefer WPA2. If your router is forcing WPA3, the handshake might fail intermittently.
Is it the SD Card?
This is a weird one, but it’s real. If you have a microSD card in the camera for local recording and that card is corrupt or dying, it can hang the camera’s processor.
When the processor hangs, the network stream drops.
Try popping the SD card out and running the camera for a day. If the code -45 disappears, your SD card was the villain. Use a "High Endurance" card specifically designed for security cameras. Standard cards can't handle the constant writing and rewriting.
When to Call it Quits
Sometimes, hardware just fails. If you’ve reset the camera, changed the Wi-Fi channel, moved the router closer, and tried a new power cable, and you still see code -45 every time you try to view the live stream? The internal Wi-Fi radio might be toasted.
Heat is the enemy of these small cameras. If yours is in direct sunlight all day, the internal components can degrade.
Actionable Steps to Fix Code -45 Today
Don't just keep hitting "Retry" in the app. It won't work.
- Check your signal strength in the app. Anything below two bars is a gamble. If it's low, move your router or get a cheap Wi-Fi extender.
- Toggle your phone's Wi-Fi. Sometimes the error is on the phone's end, not the camera's. Switch to cellular data and see if the stream loads. If it works on 5G but not on your home Wi-Fi, your router is blocking the stream.
- Update the Roku Smart Home app. Go to the App Store or Play Store and make sure you aren't running an version from six months ago.
- Check Roku's Service Status. Google "Roku server status" or check sites like Downdetector. If Roku’s servers are down, no amount of rebooting your router will help.
- Force a 2.4GHz connection. If you have a mesh system, temporarily disable the 5GHz band while you set the camera up.
- Replace the power block. The little USB cubes that come with cameras are notoriously cheap. If it isn't providing a steady 5V/1A, the Wi-Fi chip will be the first thing to flicker. Use a high-quality phone charger block to test it.
Fixing a code -45 is mostly about process of elimination. Start with the software (reboots and updates), move to the environment (Wi-Fi interference), and finally look at the hardware (SD cards and power blocks). Most of the time, a simple channel change on your router solves what seems like a permanent hardware failure.
