Q:How to use video surveillance video surveillance
Forget to tell you, a decoder card (4 Road Dahua) 1200 yuan, 300 yuan conversion interface.
Q:What is the number of lines that a surveillance camera needs to use?
General monitoring of the camera needs a line of power lines, video lines, audio lines and so on
Q:Monitor the camera hemispherical gun shape which is good
Both are different from the installation site, the dome camera is only installed in the indoor site, gun camera can be installed indoors can also be installed outdoors. The dome camera lens due to the installation site is small, it's fixed lens only 3.6 - 8MM three; and gun-type camera it's fixed lens to have a variety of 3.6--16MM, so it's big camera Far more, but according to the angle of the small lens is not wide.
Q:Wireless surveillance camera security is not? Easy to be peeped not? LAN and external network access speed how?
This depends on your own, and manufacturers want to remotely monitor your camera can certainly see, because you are remotely through the manufacturers of the background server, the password what the background still see, of course, speed must be connected with your camera The network and your terminal to receive a relationship with the network.
Q:Monitor the camera must be a separate threading it?
1, to facilitate future maintenance 2, to avoid sun and rain 3, to avoid strong interference and other
Q:Monitor the camera gray screen
2, the camera itself quality problems. Now a lot of domestic miscellaneous brand camera, the background running program is very poor, resulting in excessive heat of the camera, over time, there will be a variety of problems. The general situation is color black and white. Suggestions for hundreds of pieces for a good brand, for example: like a cottage Apple phone and the middle of the gap between Apple.
Q:Buy monitor camera attention to what
Due to the manufacturers in the DSP and related technology between the level of differences, so the product is also different, so the parameters are marked with the gap, and some marked 500 lines, and some standard 520 lines, there are marked 530 lines, the highest marked 540 lines, Even 600 lines. So a variety of line number classification, in fact, shows the differences between the various, of course, which also mixed with a small amount of domestic enterprises to 480 lines fake 500 lines above the product composition. In fact, even in the same 540 line products, because the manufacturers of production technology differences and DSP technology differences, the same line of products with different results. But with the naked eye to distinguish is more difficult to compare out, unless the professional testing equipment or image magnification to distinguish, or find one or two real high-end brand camera to contrast. But in essence, 520 lines or more are called high-definition cameras, but analog cameras in the existing DSP and manufacturing technology based on a limit upgrade, it will be the traditional 480 line HD standard to 520 lines Or 540 lines.
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:Camera monitor the recorded file 1 hour how much G ah?
Monitor video 24 hours per channel per day Recording space size calculation formula:
Q:An accurate calculation formula for monitoring the focal length and actual distance of the lens
The size of the imaging scene and the size of the imaging object are contradictory, for example, with the same camera to monitor the same parking lot, the choice of short focal length lens can be the entire parking lot to monitor and see the entrance Outside the vehicle out, but can not see the car's license number (the car in the monitor screen only occupies a small area)
