Q:Night to monitor the infrared light is not bright because it is not open monitoring?

4: into the camera's settings menu, and some cameras can be forced to turn off the infrared mode, that is, has not opened.

Q:How to remotely monitor the phone

2, with the network cable through the computer connected to the switch, you can see the online camera, and can also be connected through the Wifi wireless network IPAD, notebook, first of all to see if this camera is to support mobile phone viewing, if supported and this IP CAM has Access to the public network, and the phone is a smart phone that can be remotely monitored online, you can also use the NVR recorder to connect the switch, use the display connected to the video recorder can be seen at any time to monitor the recorded screen images, remote users can Log in to the IPC domain to view, control, manage and record IPC. Remote user login IPC can be through the web browser (IE) and the corresponding video centralized management software to achieve, the operation is very convenient, so that you can use the normal network camera.

Q:Why mobile phone surveillance camera is always not online

Can be connected to the switch through the NVR recorder, the use of the display connected to the video recorder can be seen at any time to monitor the recorded screen images, remote users can log on IPC domain name to IPC to watch, control, management and video. Remote user login IPC can be through the web browser (IE) and the corresponding video centralized management software to achieve, the operation is very convenient, so that you can use the normal network camera.

Q:What is the difference between a camera's double point and a single lamp point?

Array infrared night vision technology, the essence or through the camera to launch active infrared light way night vision effect, but the use of advanced packaging technology, dozens of high-power, high efficiency of the infrared crystal package in a plane. The advent of this technology, access to the extraordinary rapid development.

Q:Monitor the video recorder has been unable to work what is the reason

VCR hardware is damaged. This situation is recommended to contact the dealer for the repair.

Q:Police surveillance camera and civilian What is the difference?

Q:The working principle of the camera with infrared light

First, the characteristics of infrared and infrared light light is an electromagnetic wave, with the same nature as the radio waves. Its wavelength range is from several nanometers (1nm = 10-9m) to about 1mm (mm). The visible wavelength is from 380nm to 780nm, the wavelength of visible light from long to short into red, orange, yellow, green, blue, blue, violet, the wavelength is shorter than the purple light, the wavelength of visible light is only a part of the visible light, visible light Called ultraviolet light, the wavelength is longer than the infrared light called infrared light. Infrared light wavelength between 780nm ~ 1000μm, located between the radio and visible light. Infrared light according to its infrared radiation mechanism is divided into semiconductor solid light (infrared emission diode IR LED) infrared light and heat radiation infrared light two. At present in the CCTV infrared camera in the former use more.

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,
