Fix CCTV Camera Blurry Image- Full Guide for HD & IP Cameras

CCTV cameras are the modern guards. They protect our homes, businesses, people, pets, and properties. They have become an integral part of our lifestyles. Through CCTV cameras, we can monitor our locations and work remotely. We remain connected with our family members and coworkers 24 * 7.

Now, suppose if CCTV cameras’ images are not clear and vibrant, we will fail to view things clearly. Blurred images are like blind spots. When vision is not clear, we won’t be able to pinpoint threats and dangers.

The post guides users on how to ‘fix CCTV camera Blurry Image’. We will discuss here the reasons and their solutions.

How to Recognise Blurred Images?

It is so easy. When things are hazy and you can’t easily recognise faces and activities, then it means that the image quality is poor. These blurred images are hampering your secure monitoring and surveillance.

These blurry image problems could occur in Analog, HD, and IP cameras. All modes of CCTV devices face these issues. We will here guide you step-by-step to handle such issues.  

Why CCTV Cameras Show Blurred Images?

If we have to resolve any issue, we must have firsthand information about the problem. There are certain reasons that trigger blurred images in the CCTV System.

1- Lens Covers are Dirty & Dim– Lenses gather dust and moisture. They block good vision.

2- Low-Resolution Cameras- Sometimes, low-resolution cameras are installed at locations capturing large areas. They produce low-quality, blurred images.

3- Lens Focus Issues– The camera lens is not set properly for focus.

4- Locations are not set properly– Sometimes, cameras are not installed at proper locations. Bright lights or low lights hamper good camera vision.

5- Lens Glare Issues– When any light or sunlight direction is directly on lenns, we get blurry images.

6- Loose or Faulty Cables– When cables are loose or faulty, we face signal and video quality loss.

7- Faulty Cameras– Sometimes, old, cheap, or faulty cameras pose poor image threats. Poor lenses or worn-out cameras give lower-quality images.  

8- Firmware & Software Update Required– Sometimes, camera firmware and DVR/NVR software updates are required. If they are not updated, we face interruptions and vision problems.

Now, let’s go step by step and fix the problem.

Fix CCTV Camera Blurry Image- Step-by-Step Guidance

We will discuss here in detail about issues and their solutions. The solution is universal for Analog, HD, and IP cameras. Because these issues create image issues in all modes of cameras.

1- Clean the Camera Lens Carefully

• Whether you are using an Analog, HD, or IP Camera, this hack is a must.
• Wipe the camera lens with a piece of cotton or cloth. Do it gently.
• It will remove dust particles, cob webs, and moisture on and around lens areas.
• Dome cameras are designed in a way that their housings are also required to be cleaned. The camera cover and lens are almost side by side. Cleaning it may help with clear vision.
• If there is moisture inside the device, use a good-quality weatherproof camera. You can also use silica gel packets inside the housing.  
• Many times, simply cleaning the lens solves the blurry vision problem.

2- Adjust the Camera Focus Settings

Analog, HD, and IP cameras are different models. Technically, their focus adjustment techniques are different.

Analog/HD Cameras

• In most Analog and HD cameras, we have a focus ring.
• Adjust the focus ring as per the requirement by opening the housing.
• If you are using a varifocal camera with a zooming lens, adjust both zoom and focus for the best clarity.

IP Cameras

• IP cameras have an auto focus feature. You can also use NVRs to focus cameras.
• If you are using a fixed lens camera, then there is no need for focal length adjustment. It remains fixed.

3- Check the Camera Resolution & Its Settings

• To fix the blurry image problem, adjust the device resolution.
• Adjust resolution settings through DVRs and NVRs.
• Make sure that the resolution is set to full HD 1080p or higher.
• Avoid using low-resolution cameras like CIF or D1. They will always produce poor image quality.
• In IP cameras, run the system in the main stream. It is a selection for high-resolution images. If the system is set on the sub-structure option, it will give low-resolution images.

4- Check the IR Quality & Light on the Camera Lens

• If the image is blurred, check if the IRs are reflecting or not. If they are reflecting on nearby areas and items. Improper IR LED reflection is the main cause of blurry images.
• Do not install cameras behind glasses. They will never give a clear vision.
• Adjust camera angles and IR LEDs to maximise the light absorption for clearer images.
• Sometimes adjusting camera angles alone solves the poor image problem.

5- Adjust & Manage Camera Brightness, Contrast, Colour, WDR, DNR Features

• The camera image setting has options to improve the image quality.
• Adjust brightness if the image is dull or too contrasty.
• Increase contrast and sharpness slightly for clearer images.
• If the WDR(Wide Dynamic Range) feature is given, then enable this feature. It gives extremely clean images in low and contrasting lights. In the dark background, it gives detailed images.
• Adjust the backlight compensation (BLC) feature if given the option to manage sunlight glare.

6- Check & Fix Cables & Connectors

Analog & HD Cameras

• Here, check the coaxial or RG59 cables and see if there is any damage, puncture, or loose connection, and fix it.
• Check BNC connectors and either tighten them or replace them with the new ones.
• Use quality cables for cameras and power. The image quality will improve.

For IP Cameras

• Check the Cat5e and Cat6 network cables and fix issues if there is any.
• Check RJ45 connectors and, if needed, replace them.
• Check the network speed, bit rates, and bandwidth. If the bit rate or the bandwidth is too low, it will give low low-quality image.

7- Replace Faulty Cameras, Cables & Connectors

Sometimes, every possible checkup doesn’t solve problems. The image quality remains blurry. Then, it means we are dealing with faulty products. Either the camera or the cables needs replacement.

• Change the camera, and maybe the issue will be resolved.
• Use a camera with 1080p and above for a quality image and footage. 2MP, 4MP to 4k+ cameras are great.
• Changing cables and automatically imaging will improve.

8- Camera Firmware Update/ DVR/NVR Software Update

• If we have outdated firmware, we may face bug issues and image quality problems.
• To update firmware and software, visit the company’s website and download the latest firmware for the device model.
• If there is any updation problem, then after the updation, it will automatically solve the poor mage problem.

9- Check External & Environmental Factors

• There are some harsh outdoor environmental conditions that can damage the system.
• Fog, rain, or direct sunlight can damage devices and blur images.
• Use waterproof and weatherproof cameras.
• Use a heated camera housing in moist environments.
• These precautions will maintain the image quality of your IP, HD, and Analog cameras.

10- Increase Bitrates & Bandwidth in IP cameras

• If the network is slow or overloaded, viewers may get blurry images.
• Go to increase the camera bitrate. A higher bitrate means improved image quality.
• Higher bandwidth is important for quality images.
• Use at least H.265 compression for better clarity.
• Use a Gigabit switch for long-range IP cameras for better image quality.

These are the 10 recommendations to get quality images. These steps will obviously eliminate poor image quality.  

Some Special Tips for Improving Image Quality in Analog & HD Cameras

• Use quality cables and CCTV devices.
• Don’t exceed the cable lengths to their maximum limit for device installation. Use jointers for long cabling.
• Make sure that the DVR and camera are compatible. The cameras and DVRs are in the same format of TVI, AHD, and CVI.
• Adjust the camera lens ring carefully. A small misalignment can cause blur.

Some Special Tips for Improving Image Quality in IP Cameras

• Always set the IP stream profile on the main stream for HD clarity.
• Use PoE switches for a better data and power supply for improved image quality.
• Enable the auto-focus option if your IP camera has this feature.

Some Precautions for Great Image Quality

• Clean camera lenses every 2–3 months.
• Prefer weatherproof and bullet cameras for outdoors.
• Check cables off and on. Fix loose connections and damaged cables & connectors.
• Keep the firmware and software updated.
• Fix cameras at suitable locations and in proper lighting.
