Q: 57 Road 1080P surveillance video requirements to store a month, how much hard disk space?: Need 91T or so hard drive, high-definition quite occupied hard disk, 720P basic to a small half,

Q: How to connect a hard disk video recorder to a computer: (2) If there is only one hard disk recorder, you do not need to purchase the switch, and use the crossover cable (one end of the other end B head) to connect the hard disk video recorder and computer can be. Use the computer to access and control the hard disk recorders: use IE browser in the address bar typing http: // hard disk video recorder IP address: port number to open the login page, enter the hard disk recorder administrator account and password on it.

Q: There is a surveillance camera, want to adjust the location, hand touch the head, even live, do not know how the matter: There is one may be your power leakage, and this will be carefully checked, the host, the camera power supply, to prevent human shock, some equipment, metal shell is best connected to the ground.

Q: How to monitor their own home in the home camera, in the first floor, in the 5th floor to see!: VCR simple, you put the host downstairs, a line upstairs, then the TV can see. Disadvantages: uncontrollable.

Q: What is the number of millimeters that monitor the camera?: And then the zoom is generally wide angle is more than 90 degrees above the normal is about 30 degrees long focal length is less than 20 degrees

Q: The working principle of the camera with infrared light: Infrared emission diode (IR LED) infrared lamp principle is: by the infrared light-emitting diode matrix composed of light. Infrared emission diode from the infrared radiation efficiency of high materials (commonly used gallium arsenide GaAs) made PN junction, plus forward bias voltage to the PN junction injection current excitation infrared light. Spectral power distribution for the central wavelength of 830 ~ 950nm, half-peak bandwidth of about 40nm or so, it is narrowband distribution, for ordinary CCD black and white camera can feel the range. The emission power of the infrared light emitting diode is expressed by the irradiance μW / m2. The maximum radiation intensity of the infrared diode is generally in front of the optical axis and decreases with the increase of the angle between the radiation direction and the optical axis. The radiation intensity is 50% of the maximum value of the angle is called the half intensity radiation angle, that is, half power angle. The radiation angle of the infrared light emitting diodes of different packaging process models is different.

Q: Monitor the camera 1/3 and 1/4 of the difference there is nothing different CCD what is it: CCD, English full name: Charge-coupled Device, the Chinese full name: charge-coupled components. Can be called CCD image sensor, also known as image controller. A CCD is a semiconductor device that converts an optical image into a digital signal. The tiny photoreceptor implanted on the CCD is called the pixel (Pixel). The higher the number of pixels on a CCD, the higher the picture resolution it provides. The CCD acts like a film, but it converts an optical signal into a charge signal. CCD has a number of neatly arranged photodiode, can sense the light, and the optical signal into electrical signals, the external sampling amplifier and analog conversion circuit into digital image signal.

Q: Does the infrared surveillance camera automatically alarm when someone enters the monitoring range?: This as long as your video recorder has this function can it? The general are brought, so you can find the above settings on the VCR

Q: The VCR monitors how the computer is connected: (2) If there is only one hard disk recorder, you do not need to purchase the switch, and use the crossover cable (one end of the other end B head) to connect the hard disk video recorder and computer can be. Use the computer to access and control the hard disk recorders: use IE browser in the address bar typing http: // hard disk video recorder IP address: port number to open the login page, enter the hard disk recorder administrator account and password on it.
