• Check for moisture on the lens. If moisture is an issue, consider mounting the camera in a sheltered area or adjusting the camera sunshade to prevent rain or moisture from accumulating on the lens.
• If using a bullet camera, ensure that the mounting screws are secure using the provided Allen key. Loose screws can cause the inner lens to shake and blur the image.
• Make sure the camera's power adapter is installed indoors and connected to a functional power outlet. Insufficient or unstable power can cause video feed issues. Try using a different power outlet and ensure the camera is properly connected to the power adapter.
• Check for issues with your cables, such as kinks, coils, or damage. These can cause signal bleed, create shorts, or lead to static and blurry images.
• If you are using a Varifocal Camera, refer to your camera's user manual to manually focus the camera and access the on-screen display (OSD) menu.
• If you are using a PoE (Power over Ethernet) connection, ensure you do not exceed the PoE budget of your recorder. Going over the PoE budget can result in video loss.
• If you suspect a power supply issue, swap the power supplies of the camera and the unit to determine which component is faulty.
• For specific models, such as the Lorex D871A8, issues with the resolution may cause a blank screen. To resolve this, press and hold the centre button until the screen displays an image.
• For cameras with fisheye viewing capability, launch the FLIR Cloud Client software, navigate to the Live View screen, right-click on the camera image, and select "Fisheye > View Original" to disable fisheye mode.

By following these troubleshooting steps, you should be able to resolve most distorted picture issues with your Lorex camera. If the problem persists, you may need to contact Lorex technical support for further assistance.

Adjusting the camera's zoom and focus

Firstly, it is important to identify the type of lens your Lorex camera has. There are two types: varifocal and fixed. Varifocal lenses offer adjustable optical zoom and, consequently, also have focus control. On the other hand, fixed lenses do not allow for optical zoom adjustments and, therefore, do not need focus adjustments as they are set to the correct distance from the camera sensor during manufacturing.

If your Lorex camera has a varifocal lens, you can adjust the focus by turning the screw on the lens until you achieve the desired image quality. Keep in mind that adjusting the zoom will also require focus adjustments due to the change in focal length.

For Lorex cameras with autofocus capabilities, you can adjust the zoom and focus using the camera's on-screen display (OSD) menu. Here are the steps:

• Click on the channel where the motorized lens camera is connected.
• Right-click and select 'AutoFocus' from the menu.
• Log in to your Lorex system using your username and password.
• Adjust the zoom and focus using the sliders provided. You can also hover your mouse over the sliders and use the mouse wheel to make fine adjustments of 1% at a time.
• If you want the camera to automatically adjust the focus at the current zoom level, click the 'AutoFocus' button.
• If you need to reset the camera to its default zoom and focus levels, click the 'Reset' button.
• If someone has manually adjusted the lens controls on the camera, click 'Refresh' to update the settings shown on the system.
• Right-click to exit and save the changes you have made.

It is important to note that issues with image quality, such as distortion, blurriness, pixelation, or static, can sometimes be caused by factors like installation, cables, or environmental conditions. Ensure that you periodically clean the lens with a soft cloth, prevent moisture accumulation, and check that the camera's power adapter is installed indoors and functioning properly. Additionally, review your camera's user manual for specific instructions on manually adjusting the focus for your particular model.

The impact of lighting on security camera image quality

The lighting conditions in a video surveillance setting can have a significant impact on the quality of the captured footage. Lighting affects the clarity of the footage and can cause issues such as graininess, blurriness, or washed-out images, making it difficult to identify individuals or objects in the frame.

Low Light Conditions

Low light conditions can make it difficult for cameras to capture clear images, resulting in grainy or blurry footage. This is especially challenging for cameras without low-light capabilities. Adding additional lighting or using cameras with infrared (IR) lighting or night vision capabilities can help mitigate this issue. However, too much IR lighting can cause overexposure, and not all cameras have night vision.

Backlighting and Glare

Backlighting occurs when the background is brighter than the subject, causing the subject to appear dark and difficult to see. Glare, on the other hand, is caused by a direct source of light reflecting off a surface, such as a window or mirror. Both issues can obstruct important details in the footage. Adjusting the camera angle, adding a backlight to the subject, or using anti-glare coatings or window films can help address these problems.

Natural Lighting

The position of the sun creates inconsistent lighting conditions throughout the day, resulting in areas of overexposure or underexposure in the footage. A site survey can help identify these issues and determine optimal camera placement accordingly.

Camera Settings

Adjusting camera settings such as exposure, white balance, resolution, frame rate, and focus can also improve image quality. For example, adjusting the exposure can control the brightness or darkness of the footage, while the focus setting ensures that the edges of the image are sharp and clear.

Lighting Fixtures

The use of appropriate lighting fixtures is crucial for achieving high-quality video footage. Different types of lighting fixtures, such as floodlights, spotlights, wall packs, and downlights, are designed for different applications. It is important to select the right fixture based on the specific needs of the surveillance project. Additionally, the positioning and intensity of the lighting fixtures should be considered to avoid issues like glare or underexposure.

Lorex Camera Focus

Lorex security cameras offer various features to enhance image quality, such as the ability to adjust the camera's focus. Lorex cameras with varifocal lenses allow users to adjust the focus by turning a screw in the lens until the desired image is achieved. This is particularly useful when dealing with low-light conditions or backlighting issues.

The importance of correct camera installation

Correctly installing security cameras is essential to ensure the safety of your property, family, and staff. It also helps to provide visual verification of events and valuable evidence for law enforcement. Here are some key reasons why proper camera installation is crucial:

Field of View and Lighting:

Avoid blind spots by carefully planning camera placement. Ensure that cameras are installed in well-lit areas for clearer images. Consider using infrared cameras for night vision and heat detection. Avoid positioning cameras where they face direct sunlight, as excessive light can reduce visibility and camera effectiveness.
