Q: What is the difference between monitoring the camera and the usual?: 3. Camera effect: monitoring with the camera, generally require high clarity, because the current computer camera commonly used sensor chip is Micron or modern photographic chip, these two kinds of chip camera, clarity are similar, if the use of 5 glass Lens, then the requirements are less stringent occasions are generally able to meet the basic requirements, and 30 frames per second speed is basically able to meet the monitoring needs. If you need better clarity, you can use the physical dynamic 1.3 million camera (not online nonsense 1.3 million, need to emphasize that the sensor chip and interface chip support physical dynamic 1.3 million camera, can really be considered 1.3 million ), This camera is generally better imaging results than the use of magnesium light and modern sensor chip camera, can get better than the average physical 350,000 camera effect, but the bandwidth occupied and CPU occupancy rate is very high. So easy to monitor the camera system easy to use.

Q: Monitor the camera infrared light does not shine what is the reason: Daylight is not bright, or only see the little red dot, because the infrared light only issued infrared light. People can not see, only to see the red red dot red

Q: I said is the monitoring of the camera, not what home with the camera, you can monitor the leader can also record the software, or hardware did not?: Of course, just add a pickup on the line.

Q: What is the minimum illuminance indicator of the surveillance camera?: IRE Level: The maximum amplitude of the video output of the CCD camera is generally set at 100IRE (or 700 mV), and a 100IRE video indicates that you can fully drive a monitor to show the best brightness and contrast image quality. 50IRE video shows only half the contrast, 30IRE (or 210 millivolts) that only 30% of the original amplitude, usually 30IRE is the lowest performance available image value. So there is no indication of the lowest illuminance results of the IRE grade and are not actually comparable. Finally, it is the camera's special function settings.

Q: Surveillance video can only save 4 days (the original can save about 15 days), is not the hard disk video recorder is a problem?: If that's the case, then you can consider replacing the hard drive.

Q: Explosion-proof surveillance cameras can be installed directly on the top of the tank: Need to do a bracket, can not be installed directly, need to see the actual situation

Q: Monitor inside the infrared network camera infrared light automatically switch and synchronous switch What does this mean?: Synchronous switch has not heard, another set according to set the time to switch. For example, set 18 points to night into black and white

Q: Yourself at home with a computer monitor how to install. Need to set up those. And installation steps: 1. Select the location to install the camera, the need to choose according to the needs of the scene and the situation, others can not help, come up with surveillance camera stand, ready tools and parts: up plug, screw, screwdriver, hammer, Tools; according to the pre-determined installation location, check the size of the plug and self-tapping screws, try the bracket screw and the camera base of the screw is appropriate, embedded pipeline interface is handled properly, test cable is smooth, ready After entering the installer. To meet the requirements of the target field to monitor the target conditions, the installation height: indoor ground should not be less than 2.5m; outdoor from the ground should not be less than 3.5m.

Q: An accurate calculation formula for monitoring the focal length and actual distance of the lens: While the use of long focal length lens can see the car's license number (the car occupies most of the area on the screen), but can not monitor the entire car park

Q: Monitor knowledge! 1.2 m × 20 meters of the corridor with a large angle of the camera the best?: Corridor 20 meters if it is a single exit with a camera on it, if there are multiple exports on the need to add, the hemisphere and the bolt can be, the lens point of view, to see how far to see, installed 3.6MM lens to see 3 meters Is the best effect, the wide angle of the lens can cover 1.2 meters range, the proposed installation of 6MM lens or 4MM lens, from the 6-10 meters to see the best results, covering the range of 50 ° -60 °
