Security Camera Not Working? Start With What You Can See

12 min read · Oct 17, 2026

When a security camera not working is the complaint, the fault usually sits in one of four places: power, the network connection, storage, or the image itself. The quickest fix is not to try everything at once, but to name the exact symptom — no lights, offline in the app, live view but no recordings, a black or washed-out picture, or an app error — and work only on that layer. This page sorts the symptoms and points you to the detailed fix for each one.

Menu names below may differ slightly depending on your app version, and features vary by camera model, so check the manual or label for your unit when a step does not match what you see.

Step 1: describe the problem in one sentence

"It doesn't work" can mean five completely different faults. Before touching anything, finish this sentence: "When I open the app, I see…"

Nothing at the camera at all — no indicator light, no sound at startup, no infrared glow at night. That is a power problem.
The camera is listed but marked offline, or the live view spins and never loads. That is a network or account problem.
Live view works, but playback is empty or stops at a certain date. That is a storage or recording-settings problem.
The video loads, but the picture is wrong — black, white, foggy, frozen, pink or blurry, especially at night.
The app itself complains — wrong password, no alerts, no sound, the camera disappeared from the list.

Write down when it started and what changed around that time: a power cut, a new router, a new phone, a storm, someone moving the camera. That detail often points straight at the cause.

Symptom A: no lights, no sound, no sign of life

A camera with no visible activity is not getting usable power, or it is not finishing its startup.

Check the socket. Plug a phone charger or a lamp into the same outlet. A faulty extension lead or timer switch is an easy cause to rule out first.
Check the adaptor. Look for a loose barrel plug, a bent pin or a cable chewed by animals. If you have an identical adaptor from another camera, swap it in as a test. Use only an adaptor with the same voltage and plug type printed on the original; the wrong one can damage the camera.
Reseat every joint. Outdoor cameras often have a short pigtail cable with a connector that sits in the weather. Unplug it, check for green corrosion or water, dry it, and reconnect firmly.
Watch the startup. Most models show a light, click, or play a voice prompt within a minute or two of power-on. If it boots and then goes dark again in a loop, suspect a weak supply or a faulty camera rather than a settings issue.
For battery or solar models, the battery may simply be flat. Charge it fully indoors with the supplied cable before testing anything else. If it keeps running flat, see why a solar camera stops charging — panel angle and shade are the usual culprits.

Safety: if the camera is hard-wired into mains power, or the check means climbing a ladder or working near the roof line, switch off the power at the breaker first and use a qualified electrician for anything beyond unplugging an adaptor.

Symptom B: the camera shows offline or the live view will not load

This is a very common complaint, and it is often not a broken camera. If the camera has power but the app says offline, the fault is usually in the network chain between the camera, your router and the internet.

Quick checks before you go deeper:

Did the router restart, get replaced, or have its WiFi password changed? Most WiFi cameras store one network name and password. If either changed, it will not reconnect on its own.
Is the camera at the edge of WiFi range? A camera that drops off only in the evening or in rain is often on a borderline signal.
Is your phone the problem? Switch between WiFi and mobile data, and open the app on a second phone if you have one.

The full layer-by-layer routine — power, network, then account — is in how to fix a Yoosee camera that shows offline. If the camera has never connected, or lost WiFi after a router change and now refuses to pair, follow the WiFi connection fixes instead; the usual causes there are a 5GHz-only network, an awkward password, or pairing from too far away.

For a 4G camera, offline usually means the SIM card: no data left, an expired plan, a SIM that needs its PIN removed, or weak mobile coverage at the mounting spot. Test the same SIM in a phone at the camera's location to see whether it gets data.

Symptom C: live view works but there is nothing to play back

If you can watch the camera live but the recordings are missing, the camera and network are fine. The problem is storage or the recording settings.

Check these in order:

Is there a card, and does the camera see it? Open the camera's settings and look for the storage or SD card section. If it says no card, or shows a capacity of zero, the camera is not using it.
Was the card formatted in the camera? Cards formatted on a computer, or moved from another device, often need formatting from inside the app before the camera will write to them. Formatting erases the card, so save anything you need first.
What is the recording mode? Many cameras default to motion-triggered recording. If you expected continuous footage, a quiet scene simply produces nothing to play back.
Is the clock right? A camera with the wrong date or time zone files recordings under the wrong day, which looks exactly like missing footage.

Card size limits, card types that wear out quickly, and loop recording are covered in detail in why a camera is not recording to the SD card. Once recording works again, here is how to find and save clips in playback.

Symptom D: the picture is black, white, blurry or frozen

When video loads but looks wrong, the camera is working; something is affecting the lens or the night mode. Match the picture to the cause:

Completely black, but the timestamp is moving. Something is covering the lens, the privacy mode is on (some models can turn the lens away or blank the image), or at night the infrared is off and the scene is dark. Check whether night vision is set to automatic.
White or washed out only at night. Infrared light is bouncing back into the lens — from a window pane, a nearby wall, an eave or a spider web across the glass.
Foggy or soft all the time. Dust, salt, fingerprints, protective film left on from the factory, or condensation inside the housing.
Pink, purple or strangely coloured in daylight. The day/night filter may be stuck. Power cycling the camera often frees it; if not, the camera may need service.
Frozen or stuttering image. This is usually bandwidth, not image quality. Lower the stream quality in live view (often a button marked HD/SD or similar) and see whether it smooths out. If it does, improve the WiFi signal.

For night-time problems in particular, the common causes and a simple test you can run after dark are in why a security camera looks blurry at night.

Symptom E: the app shows an error

Sometimes the camera is fine and the app is what fails. Common cases:

"Wrong password" or "device password error." There are usually two passwords — the account login and the camera's own device password — and the error does not always say which one. This guide sorts out which password you forgot.
No alerts arriving. Motion detection may be on in the camera while the phone silently blocks notifications or puts the app to sleep. Work through the notification checklist, starting with phone permissions and battery settings.
Video but no sound, or the camera cannot hear you. Check the app's microphone permission and the mute icon first. More in the two-way audio fixes.
The camera disappeared from the list. You may be signed into a different account than usual, or the camera was removed by someone with access. Log out and back in with the account you originally registered. If a family member manages the camera, they may need to share it with you again.
The app crashes or freezes. Update it from Google Play or the App Store, restart the phone, and if needed reinstall. Cameras added to your account are normally kept on the account rather than on the phone, but write down your login details before reinstalling.

Step 2: try the simple restarts, in the right order

If the symptom does not clearly fit one group, a clean restart of the whole chain clears many temporary faults:

Close the app fully on your phone.
Unplug the camera, or switch it off for battery models.
Restart the router and wait until its lights show it is back online.
Power the camera back on and give it a few minutes to boot and rejoin the network.
Open the app again and refresh the device list.

Doing it in this order matters: a camera that starts before the router is ready may fail to connect and wait a long time before retrying.

Step 3: reset only when the earlier steps failed

A factory reset is the last step, not the first. On most models it wipes the WiFi details, the device password and most settings, so the camera must be paired and configured again afterwards. It will not fix a dead adaptor, a weak signal, a full SIM plan or a dirty lens.

Reset when the camera has power, the network is confirmed working, and the camera still will not connect or behaves strangely; when you changed router and cannot get to the camera's settings; or when you have lost the device password with no other way back in. Where the reset button is and how to use it explains the process and what to do immediately after.

When to get help

Stop troubleshooting yourself and contact your seller or a qualified installer when:

The camera shows no sign of life even with a known-good socket and adaptor.
There is water, rust or burn marks inside the housing or at the connectors.
The image stays pink, cracked or partly black after a power cycle and a reset.
The camera reboots in a loop, or gets hot to the touch.
The fault involves mains wiring, a high mounting point or roof access.

Before you call, collect the model number from the label, the app version, what the indicator light is doing, when the fault started, and what you have already tried. That saves a lot of back-and-forth and helps the seller check whether the unit is still covered under the terms you bought it with.

Install or resell cameras?

If you fit cameras for homes or shops, many "not working" calls fall into the five symptoms above. A few habits reduce them:

Pair and test every camera at its final mounting spot before you leave, not on the counter.
Record the router name, the account used and the SD card status for each job, so a later call starts with facts.
Keep a spare adaptor and a tested SD card in the kit; they let you rule out the adaptor and the card quickly on site.
Show the customer the offline and playback screens before you leave, so they can describe a fault clearly later.

Frequently asked questions

Why did my CCTV camera stop working after a power cut?

A power cut can leave the camera fine but bring the router back with different settings, or restart both in the wrong order. Restart the router first, then the camera, and wait a few minutes. If the router was reset or replaced and now has a new network name or password, the camera must be paired again.

Can a security camera stop working because of bad weather?

Yes. Heavy rain can get into outdoor connectors, cold or humid nights can fog the lens from inside, and storms can damage adaptors or cut the internet. Check the cable joints and the power supply first, and dry any wet connector before reconnecting it.

How do I know if my security camera is broken or just disconnected?

Look at the camera itself. If it has lights, makes a startup sound or shows an infrared glow at night, it is powered and probably working — the problem is the network or the app. If it shows no sign of life with a known-good socket and adaptor, the hardware or its power supply is the likely fault.

Does a camera keep recording when the app is not working?

On most models, recording to a local SD card continues as long as the camera has power, even if the app or the internet fails. You simply cannot view it remotely until the connection returns. This depends on your model and recording settings, so confirm in the manual.

Should I buy a new camera if mine is not working?

Not until you have ruled out the cheap causes: the adaptor, the socket, the WiFi or SIM, the SD card and a dirty lens. Many faults turn out to be one of these. Replace the camera only when it fails the power and image checks above, or when the seller confirms a hardware fault.
