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?

Now the hard disk video recorders are generally with network transmission function. Know the product features also understand the use of places, the encoder is generally used for network monitoring.

Q:An accurate calculation formula for monitoring the focal length and actual distance of the lens: So when you need to monitor the panorama to see the local, the general should consider the use of electric two variable or electric three variable lens. Of course, in the selected lens under the premise of the use of high-resolution cameras and monitors can be monitored objects in the smaller size can also see the local details.

When the human eye can not stretch the lens to the normal position, that is, people often say myopia, the front of the scene becomes blurred; camera and lens with a similar phenomenon, when the image becomes unclear , You can adjust the camera's back focus, change the CCD chip and the lens reference plane distance (equivalent to adjust the position of the human eye lens), you can blur the image becomes clear. Thus, the role of the lens in the closed-circuit monitoring system is very important. Engineering designers and construction workers should often deal with the lens: the designer according to object distance, imaging size calculation lens focal length, the construction staff often on-site commissioning, part of the lens is to adjust to the best condition.

Q:P2p wireless monitoring camera how to achieve remote monitoring: Each mobile phone to install APP, IP address, dynamic domain name or P2P code (including cloud view) can be entered into the APP settings.

Code definition 1 General type camera 2 Integrated camera 5 Dome camera 7 IP dome camera 8 IP gun type camera

Q:What does it mean to monitor the camera channel?: Channel refers to the physical location of the video input of the camera on the monitoring matrix or the DVR device. Such as: ordinary hard disk video recorders support 16 video signals, so that the back of the hard disk video recorder has 16 video input interface, the channel refers to the physical location of these video interfaces, generally from left to right sort.

Q:Monitor the camera feel infrared: In the case of the camera with infrared light, the evening can rely on infrared imaging color lens, no light at night is not visible in the case of objects
