Security Camera Not Switching to Night Mode – Top 11 Reasons

security camera not switching to night mode

If you’re curious as to why your security camera isn’t switching to night mode, there are a few potential reasons. Maybe the time is set wrong, or there’s something obstructing the camera’s view. Let’s take a look at the top 11 reasons why you have a problem with your security camera not switching to night mode.

Why is My Security Camera Not Switching to Night Mode?

The main reason your security camera is not switching to night mode is probably because the monitored area is too bright. Many security cameras have an infrared (IR) filter that blocks out most visible light, allowing the camera to see in very low-light conditions. However, if there’s too much light (from the sun or a porch light, for example), the filter can become overloaded, and the camera will have trouble switching to night.

Security Camera Not Switching to Night Mode – Top 11 Reasons

Most night-vision capable security cameras use infrared (IR) LEDs to illuminate the environment in low-light conditions. IR LEDs operate at a wavelength that is invisible to the human eye, but can be detected by the camera’s image sensor. There can be several reasons you have a security camera not switching to night mode.

Problem 1 – Too Much Ambient Light

Too much ambient light can cause a security camera to have difficulty switching to night mode. When this happens, the light sensor can get fooled into thinking it’s still daytime, and the camera won’t activate the IR LEDs.

The camera may not switch to night mode when bright light shines directly into the camera’s lens, If the camera does not turn to night mode, the IR LED lights will not turn on, resulting a dark or fuzzy image.

To fix this problem, you can try repositioning the camera to avoid having bright light shine directly into the lens. If that doesn’t work, you try replacing lights in the area with lower wattage bulb.

Problem 2 – Dead IR LED Lights

If the IR LED lights are not working, then the camera will not be able to see in the dark. This usually happens when water or other debris gets into the IR LED block of lights. This will cause damage or burn-out of the IR LEDs.

To fix a block of burned-out LED lights, you’ll need to replace the IR LEDs. You can find replacement IR LEDs online or at your local electronics store. In most cases you’ll simply have to replace the entire camera.

Problem 3 – Insufficient Power Supply

IR LEDs require a security camera to draw more power than usual, so if there’s not enough power available, the camera may have difficulty switching to night mode.

The problem could be with the camera’s power adapter, the power outlet, or the wiring. If you’re using a battery-operated security camera, the batteries may not have enough power to run the IR LEDs.

To fix this problem, try plugging the camera into a different power outlet or use a different power adapter. For a battery-operated camera, simply changing the batteries can solve the issue.

Problem 4 – Damaged or Incomplete Wiring

If the camera’s wiring is damaged, incomplete, or not properly connected, then the camera may have difficulty switching to night mode. Check the wiring to make sure there are no loose connections or damaged wires.

To fix this problem, you’ll need to repair or replace the damaged wiring. You may be able to do this yourself, but it’s generally best to hire a professional.

Problem 5 – Camera Stuck in Daytime Mode

If the camera is stuck in daytime mode, it may be due to a problem with the firmware. The firmware is the software that controls the camera. A corrupted firmware can cause the camera to malfunction in a number of ways, including being stuck in daytime mode.

A firmware update from the manufacturer’s website can help. Also a hard reboot may do the trick. To do this, simply unplug the camera from the power source and then plug it back in. 

Problem 6 – Obstructed or Dirty Sensors

Dirt or dust can accumulate on the camera’s sensors, preventing the camera from switching to night mode. Fingerprints on the sensors can do the same thing. The most likely culprit is the light sensor, but the image sensor can also be affected.

To clean the sensors, you’ll need to open up the camera. Be careful though because this can void the warranty. If the camera is still under warranty, you should contact the manufacturer to check for warranty issues. Once you have access to the sensors, use a soft, dry cloth to gently wipe away any dirt or dust.

Problem 7 – The Target Area is Outside the Cameras Viewing Range

You might be looking at a black screen and suspect the night mode is not switching on in your camera. But if your camera is outside its effective range, the camera could actually be in night mode but not close enough to capture what you intend to see.

Check your cameras viewable range when in night mode. The images produced will likely be of poorer quality than during the daytime, but you should still be able to see something. If not, move your camera closer to the target area or try using a different camera with longer night vision range.

Problem 8 – Outdated Software

Just like a smartphone or laptop, software keeps your hardware components working together smoothly. You should keep your security camera’s software up-to-date for it to function properly. Software updates usually include new features and bug fixes. If your camera is having difficulty switching to night mode, a software update may solve the problem. 

First, check the manufacturer’s website for updates and follow the instructions to get it installed correctly on your system.

Problem 9 – Camera Not Set to Auto for Night Mode

Some security cameras will switch to night mode by default, and others can be set for different times or automatically based on lighting conditions. People sometimes forget to set their cameras to automatically switch to night mode and wonder why the feature isn’t working. 

Check your camera’s settings to ensure that it is set to automatically switch to night mode.

Problem 10 – Condensation Buildup Inside the Camera Housing

In very humid or rainy conditions, the inside of the camera housing can fog-up, preventing the night vision from working properly. Condensed water vapor can accumulate on the inside of the lens cover or dome, interfering with the sensor’s ability to detect low-light conditions.

To fix or prevent condensation from building up on the inside of your security camera, you’ll need to open up the camera housing. Once again, this can void the warranty. If the camera is still under warranty, you’re better off contacting the manufacturer before proceeding.

To remove the moisture, you can use a hairdryer on the low setting or a silica gel packet. Once the inside of the housing is dry, you can reassemble the camera.

Problem 11 – Defective or Broken Camera

Unfortunately, sometimes the problem lies with the camera itself. No amount of troubleshooting will fix a defective or broken camera. In this case, the only fix is to simply change out the camera for a new one. Hopefully you can catch the problem early enough when the camera is still under warranty.

How to Know if a Security Camera is Not Switching to Night Mode 

You might be experiencing very low quality night-time video, or perhaps you’re met with a completely dark screen whenever the lights go out. You’ll need to do some troubleshooting to narrow down the actual problem. Here’s how to know if a security camera is not switching to night mode.

What Happens when a Security Camera Switches to Night Mode

When a security camera switches to night mode, it automatically adjusts the image sensor’s exposure time and aperture. This allows more light to hit the sensor so that images can be captured in low-light conditions. The tradeoff is that these settings also result in lower quality images.

Night mode also typically activates infrared LEDs around the rim of the lens. These emit invisible IR light that reflects off objects in front of the camera, providing enough contrast for the image sensor to produce an image. 

The security camera has something called an IR cut filter. This filter sits over the lens and blocks infrared light waves from coming in through the lens during the day. Security cameras need an IR cut filter to produce realistic colors. At night, the IR filter must be moved away from the lens so the camera can pickup the light from it’s IR sensors to produce night vision.

When a security camera switches to night mode, the image changes from being in color to black and white as the IR cut filter moves away from the lens. You can usually hear a clicking sound when this happens. If the camera doesn’t switch to night mode, it could mean there is enough light for the camera to stay in color/day mode or that the camera is defective.

How to Test if a Security Camera is Not Switching to Night Mode

You can place your finger over the light sensor to test whether a camera is switching to night mode. The light sensor is a small circle usually found below the lens. If the camera switches to night mode, you will hear a click inside the camera and see the red IR bulbs turn on around the lens.

Quick Fix for a Security Camera Not Switching to Night Mode

If placing your finger over the light sensor doesn’t activate the camera’s night mode, you can try rebooting the camera powering the camera off for 15 seconds and then powering it back on.

To cut power to the camera, locate the power supply for the camera nearby where you have the DVR installed. The power supply is usually in a box with power to all of the other cameras or it will be a transformer that plugs into an electrical outlet.

Sometimes this process will cause the camera to reset itself. But if a power reset doesn’t work, you’re only other option will be to replace the camera.

Conclusion

A security camera not switching to night mode can be caused by a variety of reasons, including a defective or broken camera. If you’re troubleshooting and still can’t get your security camera to switch to night mode, it’s possible that the issue is with the image sensor or that there isn’t enough light for the camera to stay in color/day mode. You can test whether a security camera is not switching to night mode by placing your finger over the light sensor or trying rebooting the camera. If those quick fixes don’t work, then you may need to replace the camera.

FAQ 

How do I know if my security camera has night vision?

Check for the presence infrared (IR) bulbs around the lens of your camera to know if my security camera has night vision. These emit invisible IR light that reflects off objects in front of the camera, providing enough contrast for the image sensor to produce an image. The human eye cannot see IR light, but it can be picked up by the camera sensor and used to produce black and white video footage.

What does a green light on a security camera mean?

Not all cameras have green lights on them, but if you see one, it means the camera is receiving power, working properly, and is connected to its local network without any problems.

How can I improve my night vision video?

There are a few things you can do to improve the quality of your night vision video:

– Use an IR illuminator to provide more light for the camera to work with

– Move the camera closer to the intended subject

– Adjust the camera’s settings to improve the image quality

– Use a higher resolution camera to capture more detail

– Clean the camera lens to ensure it’s not dirty or obstructed

– Make sure the IR cut filter is not blocking the camera’s view

– Check the camera’s firmware to ensure it’s up to date

Do all security cameras have night vision?

No, not all security cameras have night vision. Some cameras are designed for indoor use only and don’t need IR capability. Other cameras, like those used in low-light conditions, may have sensors that are more sensitive to light than those found in traditional security cameras. This allows them to produce clear images in darker conditions.+

How do I turn on night vision on my security camera?

If your security camera has night vision, there will be a switch or button on the camera body that you can use to turn it on. Alternatively, some cameras will automatically switch to night vision mode when the ambient light level drops. You’ll know this is happening when you see the camera’s IR LEDs turn on around the lens.
