What is a low-quality security camera?
Today, every CCTV camera is marketed as a “high-quality CCTV security camera”!
You later realize that your chosen CCTV security camera is too slow or produces blurry images!
You will feel like you are trying to recognize someone through a foggy window! Indeed, low-quality cameras often have trouble capturing fine details.
So you get the gist of the action but miss out on the crucial stuff! If you experience these issues during the day, just think of how pixelated and dark the video feeds become at night or in low light.
Some low-quality cameras work in good weather, but some might malfunction the next day if it is windy or rainy!
The biggest nightmare is their short life span! They’re made with cheaper materials and components that wear out quickly. So, you’re not just dealing with poor quality images; you’re also facing frequent replacements or repairs.
If you’re dealing with any of the above issues in your CCTV security cameras and wondering which features are causing the poor quality, we provide tried-and-true solutions!
Factors that reduce performance in low-quality cameras and solutions:
- Low resolution of CCTV cameras.
- Lens quality of CCTV cameras.
- Sensor size of CCTV cameras.
- Type of camera: Analog vs digital IP cameras.
- Lighting conditions.
- Inappropriate installations and placement of CCTV cameras.
- Poor network quality.
- Dirty camera lens.
Low resolution:
If your CCTV camera lags and you struggle to detect moving people, read license plates, or see crucial details, it’s likely due to low resolution. The higher the resolution, the clearer the video feed, making it easier to capture important information.
720p Camera: Provides clearer images than older models, but not very detailed (1.3 million tiny picture dots).
1080p Camera: Gives a much clearer and more detailed picture (2.1 million tiny picture dots).
4K Camera: Offers the sharpest and most detailed images (8.3 million tiny picture dots).
A retired criminal investigator who also studied photography and graphics communication shares his views:
“Some people deliberately choose a lower quality recording rate like 720p or even 480p to give them more recording time before overwriting. A lot of businesses don’t put a priority on upgrading their CCTV systems until after they’re robbed.”
Lens quality:
The quality of the lens affects how sharp and clear the images are. Lower-quality lenses can cause distortion, blurriness, and reduced clarity.
Lens quality directly impacts image sharpness and detail. Cheaper cameras often use lower-grade lenses, which can lead to blurry or distorted footage.
A high-quality lens can improve image sharpness by up to 30% compared to lower-quality lenses, especially noticeable in detailed and close-up shots.
Sensor size:
If your CCTV security camera has a smaller sensor, it will likely produce video with:
- Lower image quality: Less detail, sharpness, and color accuracy.
- More noise: Grainy or speckled appearance due to increased noise levels.
- Poorer low-light performance: Difficulty capturing clear images in low-light conditions.
- Limited dynamic range: Difficulty handling high-contrast scenes (e.g., bright sunlight and shadows).
The size of the camera sensor affects its ability to capture light.
Most security cameras feature sensors ranging from “1/3 to 1/1.7” in size. The larger the sensor, the better it performs in low-light conditions, while smaller sensors tend to struggle.
This means larger sensors can capture more light due to their greater surface area, resulting in better image quality in low-light conditions. In contrast, smaller sensors, common in lower-quality cameras, often struggle with noise and lack of clarity.
Cameras with larger sensors can reduce noise levels by up to 40% compared to smaller sensors in low-light environments.
Analog vs digital cameras:
Traditional analog security cameras have limited resolution capabilities, making it difficult to capture detailed images necessary for identifying people or incidents.
Digital IP cameras offer significantly higher resolutions compared to analog and budget cameras.
IP cameras can provide ultra-high-definition images comparable to the quality of modern films. This clarity allows for better identification of individuals and incidents.
Advanced digital cameras such as PTZ cameras allow for zooming in on details without losing image quality.
Analog vs IP Cameras: A Comparison of Image Quality.
| Feature | Analog Camera | IP Camera |
|---|---|---|
| Resolution | Limited to NTSC/PAL standards (720×480 or 575 pixels). | Can offer resolutions up to 5 megapixels or higher. |
| Image Quality | Generally lower quality, with more grain and blur. | Significantly higher quality, with sharper, clearer images. |
| Color Accuracy | Less accurate color reproduction. | More accurate color reproduction. |
| Dynamic Range | Limited dynamic range, making it difficult to capture both bright and dark areas. | Wider dynamic range, allowing for better detail in both bright and dark areas. |
| Low-Light Performance | Can struggle in low-light conditions. | Generally better low-light performance due to larger sensors and image processing capabilities. |
Modern digital IP cameras have features like remote monitoring and advanced image processing that improve overall effectiveness.
Investing in high-quality digital IP cameras as compared to analog security cameras, enhances security by providing clearer images and additional functionalities that can be crucial in critical situations.
Lighting conditions:
Low-quality cameras often struggle in varying lighting conditions. They may produce noisy or blurry images in low light or have trouble handling bright spots.
Lighting is a crucial factor in image quality. Cameras with poor low-light performance can produce unusable footage when conditions are not ideal.
Choose cameras with infrared (IR) night vision and wide dynamic range (WDR) to improve performance in different lighting conditions.
Inappropriate installation and placement:
If your camera produces issues like glare, shadows, or obstructed views, then it may mean you have not mounted it at an appropriate angle or not installed it correctly.
Allow a professional to install and calibrate your security cameras. Professionals can ensure that cameras are set up correctly and calibrated to achieve the best possible performance.
“It makes quite a difference with professional installation. Experts ensure cameras are configured correctly and calibrated for best possible performance, which reduces issues related to image quality.” — Emily Wong, Security Systems Installer.
Poor network quality:
Is your camera lagging, dropping frames, or losing image quality? Your network quality could be the culprit, as it directly impacts the performance of IP cameras.
A stable and high-speed network can reduce video lag and interruptions, improving overall performance.
Dirty camera lens:
Yup! Sometimes dirt and dust build up on the lens of the security camera due to rain , storms or just because of cobwebs. This can severely damage the quality of your video feed.

When can you use a low-quality security camera?
- If you desire basic surveillance.
- You don’t want to store footage for later review.
- If you have a tight budget.
- You have limited internet bandwidth.
- If you want to consume less power.
If you desire basic surveillance:
In many instances, security footage is used mainly for live monitoring, like overseeing a tuck shop or keeping an eye on your driveway.
Lower-resolution video can still offer sufficient situational awareness, which is why many security cameras aren’t HD.
An HD camera does catch everything in great detail; however, for most applications, a camera of standard resolution will do just fine. It is all about finding that sweet spot between your needs, budget, and tech capabilities.
You don’t want to store footage for later review:
Higher-resolution video files take up significantly more storage space. Many systems use lower resolutions to store footage for extended periods to manage storage costs and capacity.
HD video files are large and require extra storage. Thus, if your camera recordings are in HD, you’ll need a lot of storage to save all that footage. This can increase costs and require more maintenance.
Storage space depends on resolution, frame rate, recording time, and compression ratio.
Meaning:
- Higher resolution and frame rate require more storage.
- Longer recording times require more storage.
If you have a tight budget:
High-definition cameras come at a higher cost. If you’re prioritizing affordability, a lower-resolution camera can save you a significant amount.
It’s like choosing between a Benz and a Honda — both get you to the same destination, but one comes with a heftier price tag.
You have limited internet bandwidth.
HD cameras work on extensive levels of internet bandwidth. When your internet connection is slow, the streaming of HD video will become problematic. You may face buffering or a reduction in the quality of your videos.
If you want to consume less power.
HD cameras use much more power, meaning that the camera’s batteries need to be changed frequently or that a source of constant power is required. In many situations, a regular-resolution camera suits the user better.
Why choose high-quality security cameras?
If you want clear, reliable footage capturing what’s happening, it’s worth investing in a higher-quality camera.
As the above picture shows, low-quality security cameras often struggle to accurately capture and analyze images due to environmental factors and camera placement.
Adverse weather conditions, crowded scenes, emergency lighting, or high camera angles can introduce visual distortions, making it difficult for the camera to effectively detect and identify objects or individuals.
Jonathan Potvin, Executive VP at Sirix, a leading remote live video monitoring company, shares his expert insights on selecting the right security systems.
Here is what he has to say on maximizing your security investment:
“When selecting a camera system, don’t just look at the price tag. Consider the total cost of ownership, including installation, maintenance, and potential upgrades. A slightly higher initial investment can lead to better performance and lower long-term costs.”
