Some Tips for Security people must know during installation

We know that when install cameras, we must pay attention to the installation of the location and angle, in order to avoid the occurrence of the screen suddenly bad problems.

What situations may have?  we collected the following case:

Question 1: daytime good, while excessive exposure at night, why?  

Case one: the camera is too close to the wall and the walls are exposed

Front of the camera is too close to the wall, should adjust the camera to the left position, to avoid infrared light through the wall directly into the lens.

Case two: There are trees before the camera, the trunk is exposed

Trunk of the tree is too close to the front of the camera, night vision will lead to excessive exposure of the trunk, can’t achieve night vision monitoring effect; should adjust the position of the camera, should avoid the trees.

Case three: Monitor scene has great light source, the light source is exposed

There is a lantern on the edge of the camera screen, reflecting a lot of infrared light, night vision will cause the lanterns to be exposed, the lanterns are bright, the right picture is dark.

The position of the bulb in the picture is too close to the camera, and the light is turned on and the camera will show a big halo, or camera strong convergence to see the light bulb, the other areas will be black.

To achieve a better night vision effect, adjust the current camera installation position, with the choice of WODSEE star-light camera, you can show more high-definition full-color night vision. ↓ ↓ ↓

↑ ↑ ↑ The picture shows the effect of WODSEE star-light camera

1)Open scene to install the camera should ensure that the scope of view does not appear light source cover, because the camera exposure strategy is high priority.

2)Two cameras installed as far as possible to avoid the head to head, you can monitor two directions. Do not have lights and other light sources of direct interference, so as not to affect the night vision effect.

Question 2: Bright and dark contrast, why? 

Case one: The camera is facing the sun outdoors, causing the darkness to dark, bright too bright

↑ ↑ ↑ The two scenes of the camera is outside, at a certain time, the sun will be directly reflected to the lens, the internal light relative to the outside of the sun will cause a typical wide dynamic scene. That is, very different brightness of the scene, bright place is too exposed, dark place too dark, lost all the details.

In need to monitor the scene of the shop door or window and etc., which can not avoid the situation of backlight, you need to select a wide dynamic dedicated camera such as WODSEE WDR camera. If you have installed a normal camera you can adjust the lens, to avoid direct sunlight.

PS: A lot of problems for the camera are common, effective to avoid, so that we can get a better monitoring effect!

FAQ:

1. What are the types of storage provided by the network video surveillance system?

The front-end storage is to store the video recording in the hard disk of the DVR. The center store stores the video recording on the central platform’s video server. The video storage is stored in the DVR’s own hard disk. The supported hard disk display or the disk storage supported by the network storage; the client store stores the video recording in the client’s browser to monitor the disk in the machine.

2.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.
