Q:What is the difference between a camera and a monitor?

Monitor (accurately should be called the monitoring system), including video surveillance system, infrared monitoring system, audio monitoring system and so on. Among them, the video surveillance system includes a camera (surveillance camera).

Q:Outdoor surveillance camera that kind of good, how the price

In the TV monitoring system engineering design, often involves the TV monitoring system equipment selection, especially the front-end camera part and the terminal display part of the match is very important. Therefore, we use the TV monitoring system equipment, can not be any match, according to the monitoring of the environment of the environment and the conditions of illumination and the requirements of the target to be monitored, follow a certain principle to choose.

Q:What is the difference between a network video encoder and a hard disk video recorder? And bolt machine cameras are the same as security monitoring? What kind of network video encoder used

Network video coding is a professional network transmission device for compressing and processing audio and video data. Mainly to provide video compression or decompression function to complete the image data acquisition or recovery, the current more popular MPEG-4 or H.264-based image data compression through the Internet network to transmit data and audio data processing. And the same bolt, belong to security products. Suitable for viewing images monitored by the camera over the network.

Q:Monitor the difference between the camera 720p and 1200 lines

Simply from the literal point of view, 1200 lines look better than 720P, but the actual effect, the 1200 line of the camera is through digital-analog conversion, and the effect of CMOS lens application in the simulation system, matching the problem (popular say acclimatized) , So the image of the 1200 line is much worse than the 720P image.

Q:6mm camera and 3mm camera What is the difference

1,6mm and 3mm refers to the size of the lens;

Q:Explosion-proof surveillance cameras can be installed directly on the top of the tank

Explosion-proof surveillance cameras can be considered Shenzhen Rongfang technology companies related products

Q:Is there a surveillance camera that can be plugged in

Monitor camcorder Baidu search

Q:What is the number of lines that a surveillance camera needs to use?

If it is a network camera is a network cable on it, the network camera to install the pickup, audio, video signals transmitted through the network.

Q:What is the power consumption of the camera day?

This power consumption is negligible. The The 10 cameras plus 24 hours can consume about once electricity

Q:What is the camera's shooting range? How much is the diameter?

The lens used in the camera is similar to the SLR camera, and is arranged in the order of 2.8mm, 3.6mm, 4mm, 6mm, 8mm, 12mm, 16mm, 24mm and so on. The smaller the number of millimeters, the wider the picture taken by the lens, but the closer the distance is; the larger the number of millimeters, the narrower the screen taken by the surveillance camera, but the farther the distance is.
