How to Know if CCTV Is Working: Common Security Camera Issues
September 13, 2024
Last Modified On: October 8, 2026
To know if a CCTV camera is working, check three things: the status light is on, the live feed loads on your monitor or app, and you can play back footage from the last hour. If any of these fail, the camera is not recording properly.
Below are the quick checks, the 5 most common CCTV problems and how to fix them, and when to call a professional.
| Check | What to look for | If it fails |
| Status light | Red, amber, or IR glow during operating hours | Check power supply, cable, and settings |
| Live feed | Clear live image on monitor or app | Check network or cable connection |
| Playback | Footage from the last hour plays back | Check storage and recording schedule |
| Storage | Drive is not full; recordings overwrite on schedule | Free up space or switch to motion recording |
Storage estimates are based on Reolink’s CCTV storage guide. If a camera fails more than one check, see the 5 common issues below or contact a managed cybersecurity and CCTV provider.
How to tell if a CCTV camera is working
Check the visual indicators
Most cameras show a red or amber light near the lens when powered on and recording. If your camera has infrared night vision, you should also see a faint glow from the IR LEDs in low light.
If these lights are off during operating hours, that’s your first sign something’s wrong, whether it’s a power issue, a settings change, or a full hardware failure.
Run a Hands-On Test
Physically inspect the camera for visible damage, dust buildup, or obstructions like spider webs or overgrown branches blocking the lens. Then check the live feed through your monitor or the manufacturer’s app to confirm the video signal is active.
Pull up footage from the last hour and confirm it plays back cleanly. Doing this monthly, not just when something seems wrong, catches problems before they turn into a gap in your coverage.
Use monitoring software
Most modern NVR and IP camera systems include an app that shows real-time status and sends alerts if a camera goes offline.
Some systems also include diagnostic tools that flag unusual behavior, like a sudden drop in resolution or a camera that stopped transmitting metadata, both of which can indicate a failing sensor or a spoofed device on your network.

5 Common CCTV issues and how to fix them
1. Poor image quality
Usually caused by a dirty lens, wrong camera settings, or aging hardware. Clean the lens with a soft, dry cloth first. If the image is still blurry, grainy, or discolored after cleaning, check the resolution and bitrate settings in your NVR, since a mismatched setting can silently degrade footage quality even when the camera itself is fine.
2. Camera positioning and angles
Blind spots usually come from poor initial placement rather than a hardware fault. Walk your property and check for new obstructions, like landscaping that’s grown in or a parked vehicle that wasn’t there during installation.
Review camera angles at least twice a year, since even small shifts in mounting hardware can drift a camera’s field of view over months.
3. Connectivity Issues
Faulty cables, unstable power, or network congestion are the usual suspects. Check every physical connection for damage or looseness, and confirm the power supply is delivering stable voltage. For IP cameras specifically, network reliability matters as much as the camera itself.
A properly installed structured cabling system reduces connectivity drops compared to ad-hoc installations.
4. Infrared night vision problems
Blurry or washed-out night footage usually means dirty or obstructed IR LEDs, or settings that aren’t optimized for low light. Clean the LED array and check that nothing, including the camera’s own housing, is blocking the infrared beam.
If problems persist after cleaning, the IR emitters themselves may be degrading, which is common as cameras approach the end of their service life.
5. Recording and storage issues
Storage runs out faster than most people expect. As a rough benchmark, Reolink notes that a 1TB drive stores about 30 days of continuous 720p footage from a single camera, but only 7 to 10 days at 4K resolution, and that drops further with more cameras on the same drive.
If footage is missing or overwritten sooner than expected, check your retention settings, confirm the recording device isn’t full, and consider motion-triggered recording instead of continuous recording to stretch available storage.
Real vs. Fake Security Cameras: How to Tell
Genuine CCTV cameras have functioning internal components: an actual image sensor, working connectivity, and visible status indicators that respond to real events, not just a blinking light on a timer.
Fake or dummy cameras often mimic the exterior, sometimes including a fake red light, but have no real recording capability. The clearest test is functional, not visual: if you can’t pull up a live feed or retrieve footage from a specific timestamp, the camera either isn’t real or isn’t working, and either way, it isn’t protecting your property.
Is Your CCTV System Legally Compliant?
In the Philippines, CCTV footage of identifiable individuals counts as personal data under the Data Privacy Act, and the National Privacy Commission’s Circular No. 2024-02 sets specific requirements for anyone operating a CCTV system in a public or semi-public space.
According to a summary of the updated rules from Gorriceta Africa Cauton & Saavedra, businesses must maintain a documented CCTV policy covering footage retention periods, disposal procedures, and access request handling, and must post clear, visible notices informing the public that CCTV is in operation.
A malfunctioning camera isn’t just a security gap under this framework. If it’s supposed to be recording and isn’t, or if footage isn’t properly retained and disposed of on schedule, that’s a compliance gap too.
How long do CCTV cameras last?
Commercial-grade cameras typically last 5 to 10 years, and PoE cameras average 6 to 8 years, according to camera lifespan data from Honor Security.
Weatherproofing rating matters too: IP65 and IP66-rated housings hold up well against rain and dust for outdoor installations, while IP67-rated cameras can survive brief water immersion, which is worth checking before mounting a camera somewhere exposed.
As cameras approach the end of that lifespan, expect more frequent image degradation, connectivity drops, and IR failures, the same symptoms covered in the troubleshooting sections above.
When to call a professional
Some issues, a dirty lens, a loose cable, an obstructed view, are fine to handle yourself. Others aren’t. If you’ve gone through the checks above and a camera still isn’t working, if you suspect a camera on your property might be fake, or if you’re not confident your system meets NPC retention and access requirements, it’s time to bring in a professional installer rather than keep guessing.

Frequently Asked Questions
How can I tell if my CCTV camera is actually recording?
Check that the status light is on, the live feed loads in your app or monitor, and footage from a recent time plays back. If any of these fail, the camera is not recording properly.
Why is my CCTV camera not working?
The most common causes are a dirty or blocked lens, poor positioning, loose cables or power problems, infrared issues at night, and full or misconfigured storage. Check them in that order.
How long should CCTV footage be kept in the Philippines?
There is no single fixed retention period. NPC Circular No. 2024-02 requires businesses to document how long they keep footage and how they dispose of it, based on a legitimate security purpose and any industry rules.
How do I know if a security camera is fake?
Try to view its live feed or retrieve footage from a specific time. If you cannot do either, the camera is not working or is fake.
How often should CCTV systems be serviced?
Do visual and functional checks monthly, review camera angles and mounts twice a year, and evaluate cameras more closely once they are 5 to 10 years old.
