FAQ:

1.Network video surveillance system monitoring center equipment how to control the big screen?

High-end users of the monitoring center most of the need for video wall display, in the network video surveillance system monitoring center through the digital decoding matrix for digital signal to analog signal conversion, and ultimately to the front-end equipment to switch to the TV wall.

2.How to choose a infrared camera?

Infrared camera is mainly used for the target needs day and night surveillance, with special emphasis on the need to monitor the night, and the target environment is not too strong light scene conditions. The specific choice based mainly on the camera and the target before the distance, the general distance of the infrared camera range of 20-100 meters, the farther away from the price the more expensive, while power consumption is also large.

In addition, the choice of infrared camera should consider the infrared light power switch control problems. This problem can be used both manual and automatic control.

3.Can different manufacturers video server connect to different manufacturers network video surveillance system platform?

At present, the manufacturers of video server equipment can only access to the interface has been docked through debugging, because the terminal interface has not completely industry standards, so temporarily can not fully realize the terminal manufacturers and any platform docking.

4. What is Highlight Compensation (HLC)?

Highlight compensation is a feature that came out of necessity due to overexposure from strong light sources like headlights or spotlights. This feature senses strong sources of light in video and compensates for exposure on these spots to enhance the overall quality. HLC is very helpful in preventing blinding of security cameras at night time from headlights.  License plate readability is a feature nearly everyone wants and expects from their security cameras placed in parking lots and entry points. Without HLC this is something that is simply impossible due to the bright, glaring nature of headlights. With the type of HLC provided in most security cameras these days it is possible to reduce the glare in video to an extent and make it possible to see license plates on slow moving front approaching vehicles or stationary vehicles. But if license plate capture is a feature you are in need of for vehicles moving faster than 5mph we advise using actual license plate capture cameras that are specifically designed for this purpose and will perform better because they have other features in addition to HLC that aid in plate capture. One such feature is shutter rate control.

5.What is Backlight Compensation (BLC)?

Backlight compensation is a feature that camera companies have been utilizing for some time now. When someone is say sitting in front of a window, or coming in from outside, there is a lot of natural light behind this person. When a camera is aimed in their direction, the camera is picking up all this natural light behind them, therefore the object or person in the foreground becomes very dark, almost silhouette like. Such video is not good for security personnel trying to determine who this person is.

BLC is a feature provided by the Digital Signal Processor (DSP) in a security camera that optimizes exposure in the foreground and background of security video. It splits the video scene into different regions, and uses a different exposure for each of these regions. It corrects regions with extremely high or low levels of light to maintain a normal and usable level of light for the object in focus. However, it is important to note that BLC has its limits when correcting exposure in situations where there is an extreme difference in light between the foreground and background. For best results, WDR has become the sought after feature.

1).Image Sensors

Image sensors are very important pieces of technology located within your security cameras. The image sensor is the component that captures the light hitting  your camera’s lens, turning it into electrical signals which get recorded as video. The two types of sensors used with security cameras are CCD and CMOS sensors. Both have their advantages and disadvantages. Below is a brief summary of each type, and you can find our more about CCD and CMOS image sensors.

2).CCD Sensors

CCD Sensors are prevalent in analog cameras specifically as a very high quality sensor.  These sensors are what make a Real WDR camera possible along with a DSP like Effio-V. Megapixel CCD sensors are very expensive and because of their cost, most high definition and IP cameras in the consumer market have CMOS sensors instead. This is unfortunate as CMOS sensors lack some features that are only available in CCD sensors. CCD sensors have the highest light sensitivity available, but aren’t best for every application. CCD sensors are capable of holding a large signal in any individual pixel and a very low read noise, meaning they have a much larger dynamic range than CMOS sensors. While CMOS may be better for speed related applications, CCD sensors are much better for applications where low noise is needed, specially in low light..

3).CMOS Sensors

As already stated, most HD and IP cameras are now using CMOS sensors.  CMOS sensors have some advantages and drawbacks when compared to CCD sensors. The rate they can convert images to digital data is much faster than what CCD sensors can provide, so overall they are much faster. They also require lower voltage and have lower power consumption. Unfortunately they generate a lot of electrical noise, leading to a sometimes grainier image. Many manufacturers are incorporating different technologies into their cameras to aid with this however. Also, Real WDR is not available in CMOS sensors at this time, and this is why DWDR and similar techniques are employed through the DSP.
