How to change the surveillance camera into a camera

1. How can I exchange my mobile phone for a surveillance camera?

If you have an idle Android phone, you can completely realize the remote monitoring function through it. Here's how to turn an Android phone into a surveillance camera:

First of all, we should choose the corresponding software to realize the monitoring function. There are many different security camera software to choose from on the Android platform, all of which provide convenient cloud functions. Here we take a home video stream as an example to demonstrate.

After entering the software, you can see a real-time image. Click on the upper left corner to enter the menu interface, select the first item to change the password, enter the user name and password and confirm to save. Then, write down the device's CID code (in the upper right corner of the screen), and then put the phone in the right place.

There are also some tips on how to place mobile phones. You can use some objects to support it, or choose a special bracket. You can choose a slightly hidden position such as a bookshelf and do some camouflage; It is best to have a power socket to ensure uninterrupted power supply for the mobile phone.

After placing the phone, you can view the monitoring screen through another Android or iOS device. A device can add up to 5 cameras, which is very convenient. However, the application is limited to android or iOS system, and it cannot support Aindows and Mac desktop system. First, you need to download the "AtHome Camera" application in the software store, then enter the software, click the Add button in the upper left corner, enter the CID code, user name and password, and click Save to connect the remote account.

At this point, click on the relevant camera, you can enter the monitoring screen, and you can take pictures, switch the front and rear cameras and switch the flash. However, the current version does not support the video recording function, and it is hoped that software manufacturers will add it as soon as possible.

2. How to convert the surveillance camera into a computer camera?

This is basically unchangeable.

1, the monitoring camera uses analog signal transmission, which requires a monitoring card to connect to the computer. 2. The video AV signal line is used to monitor the camera, and the notebook does not have this interface.

So even your notebook is a problem. And there is no such adapter.

Because it is impossible to convert analog signals into digital signals with only one adapter. 3. The signal line and power line of the surveillance camera are separated, unlike USB used in computers.

In terms of power supply, the output power of notebook USB interface can't meet the demand of surveillance camera. 4, the drive is not solved. Anyone who has done monitoring should know that the camera is not a driver, and the driver is just a monitoring card.

After installing the driver of the monitoring card, the camera can be connected to the monitoring card. Even if you can do the first three points, you can't.

3. How to change the surveillance camera into a video camera?

You can't,

At present, the cameras used for video surveillance are all CCD chips. Their advantages are durability and good definition, and the edge image will not be blurred due to aging. If they are bad, they are just bad. They cannot be used directly. Computers all use CMOS chips. Before CCD appeared, CMOS was used for video surveillance. But the disadvantage is that it can't meet the demand of 24-hour monitoring. After the aging of the chip, the imaging effect will drop a lot. Life expectancy is almost two years. Some can still be used for several years. But the performance is far behind. Infrared night vision means that the camera can sense infrared light. General color sorters are not sensitive to infrared light. There are also color cameras specially adapted to infrared light, but the price is more expensive than ordinary color machines. A black-and-white camera senses infrared light. Ordinary night vision generally uses the bottom illumination of the camera to capture very weak light. Generally, the illumination of a black-and-white machine is lower than that of a color machine. There is no additional light source at night, and it can be roughly in phase, but the effect is average. There are many other ways to realize night vision, such as using anvil accumulation, but none of them are as effective as infrared lamps. Because the chip is different, it can't

4. How to convert the surveillance camera into a webcam?

If the ordinary analog surveillance camera needs to be transmitted through the network, it needs to be equipped with a network encoder, which has the same function as the network camera.

Network video codec refers to a program or device that can compress or decompress digital video. Usually this kind of compression belongs to lossy data compression. Historically, video signals were stored on magnetic tape in analog form. With the appearance and market entry of pact Disc, audio signals are stored in digital format, and video signals are also in digital format, and some related technologies have also developed.

Functional characteristics of network video encoder

1. high definition and low bit rate: the most advanced video compression standard H.264-HP(High-Profile) is adopted for coding, which realizes the high definition and low bit rate coding transmission of VGA signals;

2. Support the setting of network access modes such as DHCP, PPPoE and fixed IP;

3. Full interface support, supporting input sources such as SDI, HDMI, VGA and CVBS, and automatically identifying various input signals;

4. Support SDI/HDMI embedded audio input, linear two-channel stereo audio input and audio gain function of audio input, which can increase or decrease the volume;

5. Support the adjustment of video brightness, contrast, definition and other parameters, video flip, mirror image and other special effects, video and audio rate adjustment, video can be adjusted from 100kpbs to 20Mbps, audio can be adjusted from 32k, 64k, 128k, 256k;

6. Support unicast, multicast and broadcast transmission, support streaming media protocols such as UDP, RTSP, RTMP, HTTP, TS, etc., and directly push the live stream to streaming media servers such as Flash Media Server, Okur Media Server, RED5, etc., and watch it through players such as Windows Media Player, Flash Player, VLC, etc.

7. The system adopts high-performance DSP processing chip, which has high coding efficiency and transmission efficiency, good real-time, good synchronization of video and audio, and the delay is less than 300 ms.

8. Support transparent data transmission (RS232/RS485) and standard pan-tilt control protocol, which can meet various applications;

9. The output video resolution can be customized, which supports the simultaneous output of network video streams with three different resolutions, three different code rates and three different protocols to meet the network requirements under different conditions;

10. Provide special decoding plug-ins, support access to low-latency decoded audio and video streams, allow clients to record live streams and set recording tasks.

1 1. provides the client SDK, which can meet various requirements of client decoding, recording and pan/tilt control;

12. Equipped with a front LCD panel, you can control the equipment through the front panel of the equipment, or you can directly access HT900 1 in any networked computer through a browser to control the encoder;

13. Perfect log information query, which can query user access, signal source status, stream publishing status and other information;

14. Built-in AMS+ streaming media service software can realize rtsp and rtmp client access and meet various forms of access such as mobile phones, set-top boxes, tablet computers and PCs;

15. Support online upgrade and online maintenance.
