Areas with inadequate lighting can be a surveillance camera installers worst nightmare. In the past, a person would fill the location with infrared light, and with any luck, adequate black and white images would be captured by the cam. Thankfully, advancements in technology have produced countless new features to make filming in the dark easier. Take these professional tips into consideration when dealing with low-lighting, and ensure that your camera provides spectacular results.
Do Your Homework
Technology offers consumers a host of benefits these days. With a few swipes of a finger on their smartphone, people can access the web. There is not a standard for measuring low-light in the security camera industry, so look over reviews and find a company that stands behind their product. On occasion, sticking with an organization that you know can prove to be a beneficial practice.
Learn The Lingo
Salespeople can become easily confused by the things consumers try to describe to them. Thus, buyers wind up purchasing equipment that does not do what they want. Spend a little time familiarizing yourself with the following terms to buy wisely.
- Night Vision
- Thermal Imaging
This type of terminology is often used by manufacturers as generic or trademark wording. However, the phrases refer to the same classification group. Know what you are getting into, and don't just rely on the not always knowledgeable clerks.
Low-Light Takes On Different Meanings
Standard infrared surveillance cameras will usually capture images between 1 and 0.1 lux. Meanwhile, some starlight cams will begin at a mere .01 lux and drop all the way down to 0.00001 lux. Don't be alarmed by not knowing what this information means as you are likely not the only one. Think of it this way, dimly lit parking lot applications will have approximately 5 lux of light. Walking into a closet and shutting the closet door will produce similar darkness.
Understand IR Illumination
Almost all surveillance cameras on the market today come equipped with IR cut filters. It filters out infrared light during the day and moves at night to let more light get to the sensor. So, most manufacturers will print the same jargon on their packaging, and it is not always easy to distinguish the difference between models. Look closely at the lens and processor specs as these items matter the most.
Another Helpful Hint
Image Toning And Processing Power Are Vital Parts Of The Equation
Since surveillance cameras have the same sensors and resolutions, processing is what sets the units apart from one another. Toning an image during the day tends to have better results than attempting the same task at night. Off-the-shelf components may not be capable of making pictures perfect in low-light, so ensure that your cam has excellent image toning and noise suppression for the best outcome.
Claims Should Be Based On Performance
Be Cautious Of Spec Sheets
Sometimes, these documents contain exaggerated claims, rather than focusing on performance. This data is often based on sensor specifications, which tells consumers about the minimal light level that the component can obtain a picture. Unfortunately, this data is unrealistic because it is nearly impossible for surveillance cameras to get decent images at 0.00001 lux. Also, know that a high pixel number does not always equal better in dimly lit locations. Choose wisely and avoid flushing your money down the drain.
