Sometimes a loose video connector can cause a double image and create blurry or fuzzy footage. This problem only applies to analog security cameras. Do a quick Google search to check the specifications of your camera. This can usually be found underneath the device. The best way to know if you have low-resolution cameras is to find the model number of the camera or digital video recorder (DVR). If the resolution of your camera is lower than these numbers, then you may want to consider upgrading to a better device with higher resolution. Resolution refers to the amount of detail a camera can capture and the higher the number, the more detailed the videos are. Low-resolution cameras can seem blurry when compared to high definition cameras.
Check if your device is still under warranty and have it replaced as soon as possible. If you keep turning the focus screws and the output is still blurry, then it’s likely that the image sensor itself is defective. Sometimes a hardware problem is a reason for that frustratingly blurry video quality. Do this at least once every four months to avoid excessive dust and dirt buildup on the camera lens. You’ll find that cleaning your security camera’s lens to be part of periodic maintenance to ensure the video quality is always clear and sharp.

This can make cleaning the lens difficult, but there is a solution to this. There are instances where the security camera is installed too high for you to reach with a ladder. Just spray the lens with water, give it a quick wipe, then you’re good to go. You want to use microfibre cloth when wiping the lens so as to avoid scratching it altogether. If you’re seeing foreign particles stuck on the videos, then you may want to check your camera’s lens and give it a good cleaning.
Dirt and dust buildup can eventually lead to blurry footage, especially during the rainy season when the camera gets dirty and wet.

These devices cannot be adjusted which means you have to set it at the right distance for it to stay in focus. Some security cameras have fixed-focus lenses, though they’re becoming less common in today’s world. However, in the off-chance that the lens is out of focus, then a simple adjustment through your smartphone’s app or through the DVR/NVR by going to the PTZ (pan, tilt, zoom) and hitting the focus button should fix the issue. Security cameras with autofocus should have no problems focusing their lenses automatically. When focusing a camera, it’s a good idea to have someone check on the monitor while you adjusting it to let you know when the lens is in focus.Īnother way is to view the cameras on your smartphone (if applicable).
