Q:What's the difference between the hemisphere and the world of security surveillance cameras?

The hemisphere is small in size and can only be manually adjusted by 360 rotations. The camera has only two interfaces, power and video, which generally support DC, 12V, or AC 24V power supplies.

Q:What are the differences between security monitoring and project and channel?

Channel products: refers to a brand, part of the goods for retail use, generally online or all types of dealers can sell.

Q:How to install home security monitoring system?

If the house is under construction, decoration, the use of wired home security system is a good choice. The outdoor monitoring system monitors the house and property facilities from invasion. If you want to install surveillance systems outdoors, it's better to use night vision cameras so that you can see images in very low visibility nights. And these surveillance cameras are also equipped with moving sensors. When can the audible alarm to detect any ring. One drawback is that these mobile probes can also be triggered by some animals (such as mice, dogs, etc.) and cause false positives. The good news is that the new detectors have been able to judge the weight and size of moving targets before they are triggered, which greatly reduces the likelihood of false positives.

Q:What are the reasons for the absence of signals in the closed-circuit monitoring system?

If you say yes, the extension cannot display the image or show no signal, and the host has an image with a signal. That's the network or the problem of setting up the extension software.It's about to be tested. If you have any questions, you can ask again.

Q:How is closed-circuit surveillance visible on the Internet?

Second, if you are connected to the camera acquisition card, we have to support remote monitoring data acquisition card, set the port, domain name and so on, and then in other network where you can directly through the IE browser to watch the real-time remote monitoring video.

Q:How to control remote control of closed-circuit system

In your way, must be in each shop to do routing in the port mapping, your network is fixed IP or ADSL class of dynamic IP, if it is fixed IP, just like LAN, easy access. If it is ADSL, it is best to do a dynamic domain name, peanut shell is good, there is free. Then your laptop with a browser enter each store access domain, or install a client software, 5 domain names to connect 5 stores.

Q:What are the common types of CCTV cameras?

The camera is divided according to the resolution:1, 480 lines, 520 lines, 540 lines, 600 lines, 700 lines, 800 lines, 1000 lines and so onThree, the camera according to the night vision effect points:1, ordinary camera. 2, infrared camera, 3, color to black cameraFour, the camera according to the imaging color points:1, black and white camera (now this camera has been discontinued), 2, color camera

Q:Check your home monitor circuit with your mobile phone

First, the closed-circuit monitoring is connected to the wireless route, which routes itself into the network. In the phone to install playback software, enter the router's IP address is fine.

Q:What is security system engineering, please?

Security system is an emerging professional which has been paid more and more attention. At present, the application of security system is becoming more and more popular and the content of technology is getting higher and higher. Almost all high and new technology can promote its development, especially the advent of the information age, but also to provide an opportunity for the development of the profession. But as far as the monitoring industry is concerned, the system composition has not been clearly divided, which makes communication between the engineering company and the user talking about the security monitoring system very inconvenient.

Q:How to distinguish surveillance cameras?

Analog camera (Camera) is a front-end device for monitoring the scene image. It takes CCD image sensor as the core component, plus synchronous signal generation circuit, video signal processing circuit and power supply. In recent years, low cost CMOS image sensor has a rapid development, based on the visual telephone or video conference system camera CMOS image sensor was applied to the requirement of image quality is not high. Due to the resolution and low illumination of the CMOS image sensor, the main target is not as good as the CCD image sensor at the moment, so the video camera is still used as a CCD camera in the TV monitoring system. Analog cameras (Camera) output signals are video signals, and can only transmit one-way video signals, which need to be connected to monitors or hard disk recorders for surveillance and video recording.
