Are Your Expectations Realistic?
When you buy a product you expect it to work right out of the packaging. Consider a new flashlight. You remove it from the packaging and insert the batteries. You expect it to work and continue working years later, even after dropping it a few times. You rely on our tools and equipment to function when you pick them up for use.
If your workplace has video surveillance security cameras then you expect them to function correctly. The security cameras should capture images you can use. You need your security cameras to provide necessary coverage with pixel density needed for quality images
Most realize the importance of lighting in capturing usable images. The lighting environment can affect image quality no matter how good your security system. The lighting in locations such as halls and breakrooms have controls. It is much easier to capture a good, usable image in controlled lighting areas.
Other locations have inconsistent lighting that varies from bright sunlight to dim lighting. Those lighting conditions make image capture difficult.
Issues with Conventional Cameras and Low Light Performance
Security cameras with standard electronic imaging sensors are poor performers in dim lighting. Some of the problems capturing images with conventional security cameras in dim light include:
Faded, inaccurate colors
Loss of detail
You can adjust your video surveillance security cameras pixel density for dim lighting. Unfortunately, the images do not get any better. The result is a useless image in which you cannot identify people’s faces.
You may try to compensate for a camera’s poor light performance by installing more lights. Electric lighting is a primary expense for any facility. Factor in the cost of the equipment and this approach is expensive indeed.
You may also try installing supplemental infrared or thermal cameras. There are downsides to these cameras. They do not provide colored images and the images are usually low resolution. Likely, the results will not be worth the cost of the equipment.
Newer Video Surveillance Cameras Improve Low Light Performance
Camera manufacturers have addressed three specific factors related to dim lighting:
- Providing lenses that gather as much light as possible to pass to the imaging sensor.
- Placing the sensor in an area for greatest quality.
- Increasing pixel resolution
- Improving signal processing and eliminating “noise”
Newer video surveillance cameras use improved image enhancement technology for low-light conditions.
The lens and imaging sensors provide improved signal-to-noise ratio. This provides accurate, consistent pixel responses. The newer cameras provide better images by utilizing:
- Processing tools such as 3D noise filtering
- Dynamic range (WDR)
- Tone mapping
The new generation of security cameras provide images that are far superior to conventional cameras.
