Q:Will a 12V10A switching power supply with a few 12V2A surveillance camera? How far can its DC current output? Please have experienced master answer, thank you
12V10A switching power supply with 5 12V2A surveillance camera.
Q:Can the monitored camera be recorded?
Of course, just add a pickup on the line.
Q:57 Road 1080P surveillance video requirements to store a month, how much hard disk space?
A camera according to the compression of an hour is roughly 2.2G, 2.2 by 24 hours 53G * 57 cameras more than 3000 G, 30 days 91000G or so, that is to say about 91T hard drive, HD quite occupied hard disk, 720P basic small half,
Q:Monitor 32 video recorders how to take 80 way camera
If you do not require the picture quality can be used to split the screen to the four screen into a road inside, reasonable arrangements can also see more than 80 cameras, but the video is four pictures can not be a separate screen.
Q:The camera used to monitor the color of the screen is not normal. Blue as red. Red out is blue. New to buy the camera
This is the reason for the collection card, the problem is installed after the acquisition card.
Q:Buy monitor camera attention to what
Because DSP and associated technology continues to improve, so many international type of camera manufacturing enterprises and domestic enterprises launched a different type of high-definition cameras.
Q:Remote monitoring principle
When the alarm occurs, the alarm decoder will be linked to the alarm output device, and through the alarm decoder to enter the alarm signal RV-2000 video terminal, and transmitted to the monitoring center, the monitoring center of the video server to receive the alarm signal immediately after the sound signal, Record alarm events, such as hard disk video alarm operation.
Q:Monitor camera parameters how to see
Focal length (f): focal length is the distance between the lens and the photosensitive element, by changing the focal length of the lens, you can change the lens magnification, change the size of the captured image. When the distance between the object and the lens is very far, we can use the following formula: lens magnification ≈ focus / material distance. Increase the lens focal length, enlarge the magnification, can be closer to the vision, the scope of the screen is small, the details of the vision to see more clearly; if the lens to reduce the focal length, magnification reduced, the scope of the screen expanded, See the bigger scene.
Q:Monitor the camera 1/3 and 1/4 of the difference there is nothing different CCD what is it
Monitoring camera is a semiconductor imaging device, with 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, can also be stored out of the charge to change the voltage, with anti-vibration and impact characteristics are widely used.
Q:What is the name of the camera with the monitor?
Called the probe, you have to look at the name of the device, do this thing too many manufacturers, the shape is the same, this is considered behind
