Q: Remote monitoring principle: Network communication using TCP / IP and network multicast (Multicast) technology, to maximize the use of the network transmission performance and network bandwidth, to avoid network congestion.

Q: 20 meters away with the number of mm monitor camera lens appropriate?: According to the imaging principle, the smaller the focal length, the wider the field of view, but the distance is not clear. The larger the focal length, the narrower the field of view, but the longer the distance will be clearer.

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: What is the black box that monitors the camera connection?: DVR is usually used analog (DVR) and network (NVR) two, look at the interface behind the fuselage can distinguish. DVR according to a few video input will have several BNC input interface, NVR is not.

Q: Monitor camera parameters how to see the bigger the bigger the better?: Lens focal length and angle Focal length Specification angle 2.1 mm Small lens 1/3 150 ° 2.5mm. Small lens 1/3 130 ° 2.8mm Small lens 1/3 115 ° 2.8mm. Fixed aperture 1/3 115 ° 2.8mm 1 / 3 96 ° 4mm 1/3 78 ° 6mm 1/3 53 ° 8mm 1/3 40 ° 12 mm 1/3 23 ° 16 m 1/3 17 ° 3.5-8 mm 1/3 96 ° - 45 ° 6-15 mm 1 / 3 54 ° - 23 ° 6-36mm

Q: HD surveillance cameras are common faults: 1) check the camera's power is normal, the infrared machine to cover the photoresistor when the infrared light will open, and can hear the sound of the IR cut switch;

Q: What is the difference between monitoring cameras CCD1 / 3 and 1/4?: The bigger the CCD is, the better. There are now 1 inch, 2/3 inch, 1/2 inch, 1/3 inch, 1/4 inch. 3.6MM lens distance of about 8 meters 6MM lens distance of about 15 meters 8MM lens distance of about 25 meters 12MM lens distance of about 35 meters is the larger the lens, you can see farther things, but see the face very little difference is 1 / 3 lens of the light through the small aperture

Q: Monitor the camera often flashing why: , The camera coding problem, 4, power supply is insufficient, 5 light dark, light sense of continuous switching, etc., 6, hard disk video recorder interface problems. There are plans to be accurate!

Q: Monitor how much power the camera has: Monitoring the head 12 volts, the general use of 2 amps, and finally their own operator

Q: Infrared surveillance camera at night (no light) no picture and flash is how the matter: Check the time, pick the evening when people come close to the camera from the place to see if the infrared light is not activated, if the start, the infrared light will have a very weak red visible light is always bright. If there is no red visible light or not always bright, it can be basically the problem of infrared light. Of course, you also need to check whether the power is normal, if the voltage is low or the current is too small, it may cause the infrared light does not work.
