Q: Monitor host can not find the camera ip how to do?
Please make sure that the equipment is working properly (power supply is normal).
Q: There are cameras at the fork in the expressway
The second is the security card mouth camcorder, the public driving through this camera often found that regardless of speed will flash lights take pictures, in fact, encountered this situation and do not panic. Its main role is to import and export vehicles and personnel to monitor the investigation of suspicious vehicle screening clues to help Interpol and other staff to trace the staff involved. This camera appearance and speed camera no significant difference.
Q: Monitor the video recorder has been unable to work what is the reason
VCR hardware is damaged. This situation is recommended to contact the dealer for the repair.
Q: How to connect a hard disk video recorder to a computer
(1) If it is in a local area network, as long as the hard disk video recorder inside the IP and computer IP in a network section on it. If you want to directly use the network cable can also, the method is the same, the first IP in a network segment, in a cross with the network cable can be connected through IE.
Q: Install the monitor camera need to put a few lines
A fixed-focus camera requires two lines, one video cable (from the recorder to the camera), a power cord (from the recorder to the camera, or the nearest socket can also be).
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: What color is the monitor when the camera is turned on?
Do not really understand what you mean, is the camera after the power of the camera after the appearance of the state?
Q: Do you want to monitor the camera?
Do not need, are generally 12V1A power supply.
Q: Commercial surveillance camera and usually use the camera is connected together? How can we find matching software?
Under normal circumstances, the ideal monitoring camera delay in 200ms or so, slightly worse IPC delay in more than 400ms. If the delay of the network camera to reach more than 400ms, you need to consider the serious delay phenomenon for the front-end equipment alarm.
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
