Q:Monitor host can not find the camera ip how to do?
And then look at the network are not connected (LAN look at the ping), is not in a network segment (192.168.1.XX or 192.168.0.XX)

Q:Elevator in the monitor camera lens focal length with the number
The smaller the number of millimeters, the greater the angle, see the closer .3.6 mm angle of about 75 degrees, the proposed monitoring distance of 5 meters .2.8 mm angle of about 90 degrees, the proposed monitoring distance of 3 meters
Q:Can the general camera be monitored?
Schools, hotels, public places Camera: with a single hard disk can be a single branch, you can also run the network, you can also real-time monitoring. Features: high rate requirements, large data capacity, long storage time.
Q:Surveillance video can only save 4 days (the original can save about 15 days), is not the hard disk video recorder is a problem?
If that's the case, then you can consider replacing the hard drive.
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,
Q:Night to monitor the infrared light is not bright because it is not open monitoring?
3: infrared detector or the camera is simply broken ... hand cover the camera above the infrared detector, if normal, then the infrared light will be bright
Q:I would like to ask how the video surveillance camera is powered?
You are right, video surveillance cameras used to make a signal with a coaxial line, and then another line when the power supply, but the two lines can also be a line to achieve. That is to use control Because the control line is a double core, with a shield, we can put the video ground, and the power of the negative line, together, sharing a line, that is, the control line of the shield, and then Inside the two core, one when the video signal is positive, one when the power is positive. This can, but if the distance is very long, it is recommended not to do so, because of this, the signal shielding will be a little interference.
