The benefits of having 3d DNR in security cameras
3d DNR has higher technical methods of process than its preceded built-in feature DNR. Where it handle the noise in two photos, one lies after the another and makes comparison between the two then 3d DNR built in feature get rid of any tiny bits that does not exist in the original frame. So it compares these two pictures within the two frames. More recently, Veilux has introduced another feature of the 3d DNR built-in where it can do more than temporal features within two frames and exceed it to handle the captured pictures within the same frame, that is by handling the process of spatial noise reduction where it detects the undesired noise and then removes it. 3D DNR built-in feature can also remove the noise from the video frame.
Well, the main benefit of 3D digital noise reduction as a circuit is to reduce the noise in the captured images and recorded videos. In addition to this basic function 3d DNR is able to improve the failure of the mixture of color and contract of colors where one of the noise resources can be dust, low- light, heat, and so on.
Since 3d DNR built-in feature in camera digital works by transferring the light into electrons then a sensor made out of silicon absorbs it where this sensor is covered by something called photosites, or pixels, which are so sensitive to light, this whole process can be easily affected by capturing the photos or recording the videos in low light environment. Therefore, 3d DNR has the ability to provide the digital security camera with the ability to capture the photos and record the videos during day and night with High Resolution and with high – quality image. The way the 3d DNR built-in feature handle the process of capturing the photos during day and night is totally amazing. The 3D DNR built-in feature is made to work under the challenge of backlit where the 3d DNR detectors switch immediately from color to monochrome depending on the luminance levels. Luminance level is a is photometric measure which measures the intensity of light. This makes the digital security camera able to capture in a very low light even on the light of the moon where this can offer more secure environment. Moreover, this feature helps the automatic turn and change of the image processing.
3D DNR built-in feature is easy to install where you can make the adjustments yourself. And one of the most important benefits is that you can place your security camera with built in 2D DNR anywhere suits you ,besides you can place them outside and inside home. In other words, you can install this feature to the wide variety of digital security camera types.
Another important feature in 3d DNR which adds to its benefits is the D-WDR. This acronym stands for Digital Wide Dynamic Range which adds to the digital security camera's ability to see in very dark light circumstances that the D-WDR provides high resolutions with high- quality images
Technology is always in progress. Manufacturers produce a new product and follow it with a series of improved products that solve the problems which exists in the preceded products with lot of facilities to meet the demands of the continual improvement in technology field.

i have a digital video recorder for my security cameras. it has a RCA output.how can i view it in my laptop?
i have a digital video recorder 500gig HDD for my security cameras. the recorder has a RCA output. how can i view it in my laptop, if my laptop connection only has HDMI and USB?
thanks in advance
You'll need to purchase a specialized pigtail which converts the RCA out to a USB connection. I believe they are available at RadioShack or at any online electronics site. I'd be surprised that your laptop doesn't have a S-video imput , so look again. It's a small circle with 4-slots inside it., if you need an example, look on the back of your TV. Be aware, you'll probably need special software to view the data, check the recorder's website to see if there's a download available. Good luck.
