Q:Monitoring camera 6mm 8mm 12mm 16mm length and width can be according to how much.

At the same time, the same focal length, length and width shooting range also with the camera CCD has a relationship. Charge - coupled Device, Charge - coupled Device. It is a semiconductor device that converts optical images into electrical signals. At present, most of the CCD chip used in the surveillance camera is 1/3 "and 1/4", that is, the target size is 1/3 inch and 1/4 inch. CCD target surface size, CCD and lens with the situation will directly affect the size of the field of view and image clarity.

Q:Outdoor surveillance camera that kind of good, how the price

Depends on your installation of specific environment, such as to see the distance, temperature and humidity, whether with infrared, etc., generally Hikvision, Samsung and Panasonic more affordable point

Q:What is the difference between monitoring cameras CCD1 / 3 and 1/4?

The bigger the CCD is, the better. There are now 1 inch, 2/3 inch, 1/2 inch, 1/3 inch, 1/4 inch. 3.6MM lens distance of about 8 meters 6MM lens distance of about 15 meters 8MM lens distance of about 25 meters 12MM lens distance of about 35 meters is the larger the lens, you can see farther things, but see the face very little difference is 1 / 3 lens of the light through the small aperture

Q:I said is the monitoring of the camera, not what home with the camera, you can monitor the leader can also record the software, or hardware did not?

Of course, just add a pickup on the line.

Q:Does the surveillance camera itself have a record storage function?

In addition, many of the network camera supports SD card video, you can video playback through the network

Q:Install the monitor camera need to put a few lines

In the case of a dome camera that can be rotated, three lines, one control line (from the recorder to the camera), one video cable (from the recorder to the camera), one power cord (from the recorder to the camera, or the nearest socket Can also be).

Q:Monitoring camera POE power supply is good, or centralized power supply good?

The use of transformer front-end power take advantage, do not have to consider the line loss, because there are transformers can reduce the loss of lightning to the lowest (of course, lightning B is not guaranteed, are force majeure; unless there is a special contract), after-sales fault detection, Check the problem is out of the camera or power problems, with the lights of the transformer is a glance!

Q:Infrared surveillance camera at night (no light) no picture and flash is how the matter

Check the time, pick the evening when people come close to the camera from the place to see if the infrared light is not activated, if the start, the infrared light will have a very weak red visible light is always bright. If there is no red visible light or not always bright, it can be basically the problem of infrared light. Of course, you also need to check whether the power is normal, if the voltage is low or the current is too small, it may cause the infrared light does not work.

Q:What is the meaning of monitoring the camera mm?

The focal length is the measure of the aggregation or divergence of the light in the optical system, which refers to the distance from the light of the lens to the focal point of the light gathering. Is also the camera (class camera) system, from the lens center to the film or CCD and other imaging plane distance. Simply say that the focal length is the distance between the focus and the vertex of the mirror.

Q:P2p wireless monitoring camera how to achieve remote monitoring

Each mobile phone to install APP, IP address, dynamic domain name or P2P code (including cloud view) can be entered into the APP settings.
