Q:What is the difference between a dome camera, a gun camera and a dome camera in security monitoring?

Mainly the use of the difference, the dome camera is generally used for indoor ceiling place, because it is relatively small, so more beautiful. Gun camera is generally installed in the channel, plant or parking area and other areas. The advantage is that you can install long focal length lens to expand the scope of monitoring, the disadvantage is more obvious.

Q:What is the black box that monitors the camera connection?

There may be a power adapter, there may be Guangduan Ji, there may be a video distributor, there may be a screen splitter, there may be a hard disk video recorder, do not know which one you say.

Q:What is the number of millimeters that monitor the camera?

Surveillance cameras generally see the 3.6 6 8 12 16MM These lenses are generally divided into wide-angle, ordinary, long focal length (these are fixed focus)

Q:Monitor how the camera is connected

2. How to use the cable connection to monitor the camera cheap. The price of the ordinary ultra-five cable is quite comparable with the 75-3 video cable, the outdoor waterproof super five cable prices are comparable with the 75-5 video. VGA cable (also known as VGA cable, signal line, image transmission line), is used to connect the host computer and monitor. The general minimum length of the standard shall not be less than 1.5M, without both ends of the thread. The market also has 1.8M, 2M, 2.5M, 3M, with a host computer, these lengths are generally used for foreign customers. The maximum length of the VGA is not a uniform standard, how long do you want to do to give you how long to do, of course, the line is too long, the impact of image transmission. Moreover, the price is very expensive, the maximum length can do 30M has been very good.

Q:What is the minimum illuminance indicator of the surveillance camera?

Therefore, the use of different F value of the lens, the camera's minimum illumination value of the determination will have a decisive impact. Second, the light source color temperature. The color temperature is an indicator of the light wavelength content in the light source. A 3200K light source is mostly between 600 nm and 900 nm, and a 9300K light source is between 300 and 500 nm, so the different color temperatures will change completely Test Results. On a typical CCD sensor, a light source with a wavelength of 600 nanometers will produce 10 times more electrons than a wavelength of 900 nanometers. This is why the color temperature is particularly marked for the meaning of the minimum illumination measurement results.

Q:Infrared surveillance camera at night (no light) no picture and flash is how the matter

Infrared light will flash, or no picture of the screen. First change the power, not the case, this camera should be broken. Under normal circumstances, in the dark, the infrared light is always bright, not flashing.

Q:Video surveillance camera pixel 1080P what it means

Meaning that the camera to collect the high definition of the screen, can support high-definition 1920x1080 resolution format video and record, reference: General DVD resolution is 720x480;

Q:Camera monitor the recorded file 1 hour how much G ah?

With the hard disk capacity divided by the size of the daily video file and then divided by the number of cameras is the number of days to save the video

Q:Network surveillance camera, at home, the mobile client can be used, but after the connection network, the client shows the ID is invalid, what is the situation?

In the home wifi, belonging to a network, outside the external network, have a fixed IP

Q:Network monitoring camera how to make external network access?

Enter the router, set the forwarding rules inside the DMZ host, the camera's internal network IP and port number can be filled into the DMZ host inside, if you do not have static IP, then have to apply for dynamic domain name (DDNS), and then you can from WAN Enter your dynamic domain name to view the camera
