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

2, may be the front of the camera connection problems, you can check the next video cable and power cord connection.

Q:3.6mm and 6mm surveillance camera can see the screen angle is how much

This depends on how much the face of the CCD friends, 1/3 is 71 degrees 1/4 is more than 51 degrees

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:Panasonic surveillance camera wv-cp704 / ch corresponding to which foreign models

3. That equipment directly connected to the computer test, whether normal. Gradually discharged to determine the key to the problem!

Q:Remote monitoring principle

First, the video signal from each camera is input to the RV-2000 video capture terminal. Then, the RV-2000 video capture terminal converts the video signal into a digital image of 25 frames per second through the MPEG-4 image compression algorithm, After the audio and video data stream through the optical fiber network forwarded to the video monitoring center; Finally, the video monitoring center of the computer to receive the front of the image and sound data from the decompression and through the computer display screen and sound card for real-time monitoring.

Q:What is the effective range of infrared surveillance cameras?

6 mm more than a narrow angle lens, the general effective distance is about 100 meters. And some 25 mm is about 150 meters, if the high-speed laser PTZ machine can reach 300 meters of infrared distance, but this cost is very high, about 13,000 or so, commonly used lens general angle is as follows: 2.8mm 101 ° 3.6 Mm 83 ° 4mm 76 ° 6mm 53 ° 8mm 35 ° 12mm 28 ° 16mm 21 ° 25mm 13 ° 1 / 3CCD and 1/4 CCD angle difference around 20 ° Hope to help you.

Q:Office area monitoring camera how to choose?

3, and then there is clarity, and optional analog cameras and network high-definition camera, which is higher pixels, the price is relatively expensive

Q:HD camera and infrared camera difference

At present the HD camera refers to the HD 1080P or HD 960P or HD 720P camera, and 1080P called Full HD.

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

The focal length is: mm. The smaller the data, the larger the shooting angle is, and the larger the captured range

Q:I would like to install at home and back door two cameras in general how much money?

According to the length of the cable, the camera's clarity is good or bad, a good camera generally a 160 or so can, the two together also 500 almost.
