Q:Now the surveillance camera really tmd nonsense, four hundred or five hundred products with more than a hundred USB camera are not as good as poor resolution did not shadow, and generally are so, monitoring products are pit father,

Mode. CMOS is complementary to each other metal oxide semiconductor, CMOS is mainly the use of silicon and germanium made of these two elements of the semiconductor, through the CMOS on the negatively charged and positively charged transistor to achieve the basic functions

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:Monitor the video recorder has been unable to work what is the reason

VCR hardware is damaged. This situation is recommended to contact the dealer for the repair.

Q:Will the video surveillance camera screen will jump out of this camera settings like the option?

If you can not quit, you can power off the camera after a few minutes to re-power, there is no, if the process is often used for no reason to jump out of the menu, you have to consider whether the control keyboard is faulty, or control the line whether there is interference , Causing garbled.

Q:Monitor the farthest distance from the camera can be far, which manufacturers out

Commonly used fixed lens camera lens focal length specifications are 4mm, 6mm, 8mm, 16mm, 25mm, viewing angle were about 80 degrees, 65 degrees, 50 degrees, 30 degrees, 15 degrees, the effective distance of 10 meters, 20 meters, 30 meters, 40 meters, 50 meters.

Q:What is the meaning of the high definition and standard definition of the surveillance camera?

HD requires a physical resolution of 1920 × 1080, that is to say the horizontal resolution to reach 1920 pixels, the vertical resolution to reach 1080 scan lines.

Q:What is the 960h in the surveillance camera?

960H is a set of quasi-HD solutions defined and developed by Techwell and Sony, which incorporates Sony's new generation of 960H CCD Sensor and Effio solutions, and the DVR side uses Techwell's latest TW9960 analog quasi-HD A / D solution. 960H resolution of 960 * 576, relative to the traditional D1 (720 * 576) overall picture clarity (details) increased by 30%. For the original analog monitoring system to upgrade the upgrade, only the front-end camera and back-end storage replaced by 960H products, transmission part can continue to follow the original system coaxial cable, the system architecture and the original analog system basically unchanged, Engineering and users without the need for professional skills training can be the original D1 system upgrade to 960H quasi-HD, the overall increase in the screen 30% at the same time will not change the user's habits, suitable for limited budget but want to experience " User.

Q:Monitor the use of the camera

This is to see what you want to do with it, I was bought to watch the baby with a baby. Emperor as faith constant, shaking his head machine! Very useful!

Q:There is a surveillance camera, want to adjust the location, hand touch the head, even live, do not know how the matter
