Description of 420TVL IR Array Waterproof Camera

420TVL IR Array Waterproof Camera

Q: Night to monitor the infrared light is not bright because it is not open monitoring?: 1: equipment power supply problems, open the infrared light to monitor the camera power is not open than the big, generally do not open when the 2 to 3 times the power, if the power quality, but the line is not enough, the total power supply UPS power is not enough Open the infrared light

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: There is a surveillance camera, want to adjust the location, hand touch the head, even live, do not know how the matter: Generally the case is the reason for static electricity, in theory, if your camera is using a transformer, that is DC power supply, then basically can be excluded from the leakage caused by the low-voltage (DC12V) camera, if There is a strong power into the words, then the camera will not be able to use, and here to note is not only the camera will have static electricity on your own may also have static electricity, you may say the same two cameras have a One is not, but you have to know the principle of electrostatic discharge, only when you come into contact with the conductive body when the static electricity can be released, you will have the feeling of Ma. In fact, if the camera is used properly, you do not have to worry about whether it is with static electricity, if you really worry, you can ground the camera, the general ceiling has a fire pipe and bridge, you can choose them to ground.

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: What is the maximum visual range of a video surveillance camera?: And the lens, light board angle, detailed advice Jinrui as surveillance cameras

Q: Hai Kangwei as the camera mapping problem: Here the network situation is so drop. A TP wireless router, a fiber cat, a monitor, two computers, and N mobile phones.

Q: How to clean the surveillance camera: Material: distilled water special cleaning agent lens paper lens rub recommended conditional deer skin (protect the lens does not wear off hair loss) method:

Q: Monitor how much power the camera has: The general camera is 5W (with infrared)

Q: Why mobile phone surveillance camera is always not online: 1, the first network camera installed, connected through the network cable to the switch, the network camera connection is not the need for each network cable must be unified in a switch (such as: need to install a camera in the distance, if you want to install ten Camera so the traditional camera is necessary for each coaxial line must be inserted at the same time in a video recorder can be used normally, but the network camera can add a switch, that has ten network switches into a network only need to pull To another switch on the normal use, so do not have to spend a lot of trouble, save a lot of labor)

Q: Monitor camera lens 4-6-8-12-16MM difference.: These numbers on the lens label refer to the focal length of the lens. The larger the value, the farther the distance the lens can reach, but the angle becomes smaller.
