Q:Test on camera delay problems
Test the network infrared camera delay problem is very simple, only need to monitor the camera at high precision stopwatch, so that the reality of the image and display the image contrast, through multiple arrests we can calculate the IPC delay time.
Q:20 meters away with the number of mm monitor camera lens appropriate?
1/4 "CCD lens in the line of sight with 1/3" CCD no difference, but the angle will be more narrow, while the shooting of the object will appear taller.
Q:Monitor the difference between the camera 720p and 1200 lines
If the above, a little knowledgeable people, will be divided into digital systems or analog systems to use these two units, but the market there are many comrades of the three classes, and no matter what the system equipment, to 忽悠 on the 忽悠, so 1200 lines are also widely used in analog systems and digital systems, which is a bit messy.
Q:HD camera is said that his clarity, infrared camera is that it's night vision function, in order to highlight the main features of the name of a
2, the lens sub-focus lens and zoom lens. Zoom lens focal length is variable, the scene can be closer to or push away, to achieve several times the zoom effect, use it to the blackboard on the board book clearly, can also be the whole picture of the classroom, the focus can not be achieved this function. Equipped with a lens for the electric three variable lens, can be zoom, focus and aperture adjustment. Zoom to zoom in and out of the picture, change the viewing angle and image size; adjust the focus and aperture, adjust the image clarity. Can be classroom teacher or a student's big picture clear real-time fixed in the entire screen, can also push to the whole class image.
Q:Yourself at home with a computer monitor how to install. Need to set up those. And installation steps

Q:How to choose to monitor the camera and video capture card?
Second, the installation of monitoring equipment needs to be sure to install several cameras and determine the monitoring range and image quality of each camera. First determine the number of cameras to monitor, and then according to the specific circumstances to determine the camera lens monitoring range: the camera must be clear to the monitoring point of the distance and the need to monitor the area, as the clarity, Ai Wei technology that: analog monitoring system 700 lines Cameras, and network digital monitoring system, millions of high-definition camera prices are very cheap, can be selected according to actual needs.
Q:Monitor camera parameters how to see
Focal length (f): focal length is the distance between the lens and the photosensitive element, by changing the focal length of the lens, you can change the lens magnification, change the size of the captured image. When the distance between the object and the lens is very far, we can use the following formula: lens magnification ≈ focus / material distance. Increase the lens focal length, enlarge the magnification, can be closer to the vision, the scope of the screen is small, the details of the vision to see more clearly; if the lens to reduce the focal length, magnification reduced, the scope of the screen expanded, See the bigger scene.
Q:What is the difference between a network video encoder and a hard disk video recorder? And bolt machine cameras are the same as security monitoring? What kind of network video encoder used
The DVR mainly converts the analog video signal into a digital signal for storage (that is, video). Now the hard disk video recorders are generally with network transmission function. Know the product features also understand the use of places, the encoder is generally used for network monitoring.
Q:Monitor inside the infrared network camera infrared light automatically switch and synchronous switch What does this mean?
