Q:Monitor there is a camera monitor can not see, but the playback can see, how is it?

1, the composition of the monitoring system principle, front-end camera ---- monitoring host ---- monitor. The camera will collect the signal to the monitoring host, monitor the host output video signal to the monitor

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:What is the difference between monitoring cameras CCD1 / 3 and 1/4?

CCD chip has developed a variety of sizes: the current use of the majority of the chip 1/3 "and 1/4". In the purchase, especially when the camera angle is more stringent requirements, CCD target surface size, CCD and lens with the situation will directly affect the size of the field of view and image clarity. 1 inch - target size is wide 12.7mm * high 9.6mm, diagonal 16mm. 2/3 inch - target size is wide 8.8mm * high 6.6mm, diagonal 11mm. 1/2 inch - target size is wide 6.4mm * height 4.8mm, diagonal 8mm. 1/3 inch - target size is wide 4.8mm * high 3.6mm, diagonal 6mm. 1/4 inch - target size is wide 3.2mm * height 2.4mm, diagonal 4mm.

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:How does the surveillance camera solve the backlight problem?

First, adjust the orientation of the entrance camera equipment, try to avoid direct sunlight from the outside, to a large extent to improve the entrance of the backlight appearance. For example, the bank door equipment needs to monitor the staff to monitor the entry and exit personnel, if we will be facing the entrance of the camera equipment, you can encounter a more severe anti-light appearance, will cause the camera to monitor the screen black, can not see what photos, At this time, the engineers will monitor the entrance of the camera flip, so that the camera lens out of the network of personnel, which is better than the role of the camera on the entrance device, you can better deal with backlight problems.

Q:What is the difference and connection between the optical zoom and the digital zoom of the camera in the security monitoring?

Optical zoom is that we often say that the mechanical zoom (manual and automatic), manual is the lens we usually zoom, auto zoom is common is that we use the ball machine and PTZ to pull closer to control zoom.

Q:Monitor the camera's focal length 4 meters good or 8 meters good

General surveillance camera focal length is not 4 meters 8 meters, and some words are estimated that the focal length of the telescope. I think you focus on the unit you did not understand, monitor the camera focal length of 2.4,4,6,8,10 ... and so on

Q:Monitor the camera's focal length how to choose?

Third, because the lens focal length and horizontal perspective is inversely proportional, so both want to see far, want to see wide and clear, it can not be achieved at the same time. Each focal length of the lens can only be in a certain range to achieve the best monitoring effect, so if the monitoring of the distance and a larger range, it is best to increase the number of cameras, or the use of electric zoom lens with PTZ installation , Of course, this for the civilian use, some expensive, and practical will not increase greatly.

Q:Monitor the camera has a video port, what is this mouth, then what machine, direct access to the TV can you?

Is BNC port, direct access to TV no problem, then the old TV video line is a BNC, one is the Lotus head, then LCD TV two are BNC; only the camera directly to the TV, then only on-site monitoring,

Q:Monitor the camera to take pictures at regular intervals

So the request is a special request, need to monitor the manufacturers in consultation, requiring the host to achieve this function, they are not difficult.
