Q:Hello, because no electric video recorder did not manually set, but I would like to look back a few days before the monitor can be transferred out
1, if the surveillance camera is only access to the monitor, no access to the hard disk video recorder, video images are not stored, you can only see the real-time picture, can not playback.
Q:What is the difference between a wireless surveillance camera and a cable surveillance camera?
Monitoring camera is a semiconductor imaging device, which has a high sensitivity, anti-glare, small distortion, small size, long life, anti-vibration and so on. Surveillance camera security system, the image generation is mainly from the CCD camera
Q:Camera clarity, 1080p. 3mp. 4k, what does it mean
4K, that is, 3840 × 2160 pixel resolution
Q:What is the number of lines that a surveillance camera needs to use?
Video cable, audio cable is a AV, BNC and other interfaces used by the line, the power cord is the ordinary power cord
Q:Monitor the camera what is the zoom
The lens is equivalent to the human eye lens, if there is no lens, the human eye can not see any objects; if there is no lens, then the camera output image is a vast expanse of white, no clear image output, which with our home camera and camera principle Is consistent. 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:Camera gun 4MM, 6MM refers to what?
Camera gun parameters in the 4MM, 6MM, etc. refers to the camera is configured lens focal length.
Q:What is the meaning of the camera function heartbeat?
In order to ensure that the heartbeat mechanism is in contact with the monitoring center when idle, a heartbeat mechanism based on the network and the host load is to use the information parameters in the network system to establish a mechanism for sensing the current network and The load condition of the host and dynamically adjusts the heartbeat mechanism of the heartbeat transmission cycle in real time according to the load condition so as to speed up the node fault detection system when the system resources are not occupied too. The "heartbeat" function is mainly used for the joint system function Of the monitoring and to achieve some of their own functions automatically switch.
Q:What kind of surveillance camera is good for the hotel?
Such as the lobby: the general use of integrated zoom camera, the scene can be a point to enlarge the details.
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.
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.
