Before you understand Intex products, I hope you have read the following knowledge points patiently. This will help you to know about mobile video surveillance! ! !
1. GSM (2G), GPRS (2.5G), CDMA1X, EDGE (2.75G), 3G wireless Internet access
China Mobile GPRS Wireless Internet China Unicom CDMA1X Wireless Internet
The maximum rate of CDMA wireless Internet access is up to 153.6 Kbps, and the rate under steady state can be around 70K-80K.
The peak rate of GPRS Internet access is 115.2Kbps, and the average Internet connection rate is 20-40Kbps.
The maximum theoretical access rate of the EDGE network is 384 Kbps, which is an over-produced product of 3G.
Domestic 3G: TD-SCDMA supports 384Kbps, upgraded TD-HSDPA will support 2.8Mbps
The Hi-Hawk system currently uses 2.5G and above networks.
2. Comparison of M-JPEG, Mpeg4, H264
M-JPEG technology is motion still image compression technology. It processes moving video sequences as continuous still images. This compression technique compresses each frame individually and completely. Each frame can be stored randomly in the editing process. Make frame-accurate edits. However, M-JPEG only compresses intra-domain spatial redundancy and does not compress the time redundancy between frames. Therefore, the compression efficiency is not high.
MPEG-4 has a very small loss of data while providing a high compression ratio. Therefore, the application of MPEG-4 can greatly reduce the video storage capacity, obtain a higher video resolution, and is especially suitable for the needs of long-term real-time recording, and at the same time, it has excellent network transmission capability at low bandwidth.
H.264 is a new digital video coding standard developed by the Joint Video Group of ITU-T VCEG and ISO/IEC MPEG. It is both the H.264 of ITU-T and the tenth part of MPEG4 of ISO/IEC. . With the same reconstructed image quality, H.264 can achieve a performance improvement of about 33% over the current video format implemented according to MPEG4.
If you want to see real-time and smooth images on your mobile phone, only the H264 encoding method can do it at present.
The Hi-Hawk system uses H.264 encoding. Real-time browsing up to 15-25fps.
3. Mobile operating system
Currently there are several operating systems Symbian, Windows Mobile, Linux, Palm
About 2/3 of smartphones worldwide use Symbian mobile operating system
A news release from Nokia on June 24 shocked the entire wireless industry: they will acquire mobile software maker Symbian.
The remaining shares, and its software open to free.
Hi-Hawk supports Symbian / Windows Mobile system smartphones and will support Linux system phones in the future.
4. What is dual-stream transmission
For the same video source, we will code it twice, all the way to D1/CIF, and the other way to QCIF. Due to the current limitation of mobile phone bandwidth, we use QCIF transmission on the mobile phone, and the bitstream is adjustable from 16Kbps to 64Kbps. . The D1/CIF is transmitted on the PC. The bitstream is 16Kbps-2Mbps adjustable. Ensure the clarity of the monitored image.
Hi-Hawk uses dual-stream transmission
After reading the above points of knowledge, maybe you want to find a similar product for comparison, I advise you to first understand the two issues, is the H.264 encoding method? Is it dual-stream transmission? If one of them is not, I can tell you not to use it now. It's not a level at all. The effect is definitely better than us! Oh, you see our confidence.
Well, I believe that you have confidence in our products and continue to look down!
1, using embedded LINUX + ARM technology (system stability), without a computer can work independently, built-in Web Server, all operations through the Internet Explorer browser or mobile phone user interface to achieve. The system supports Web browsing and supports GPRS, CDMA, EDGE, and 3G mobile wireless networks at the same time. This means that as long as there is a mobile phone network, real-time video surveillance can be realized anytime, anywhere. "Global Village" is no longer an abstract concept, but becomes a reality! Powerful, advanced design, integrated monitoring and alarm control. "Mobile video service system" can realize the remote power switch control. You can switch home appliances such as air conditioners and microwave ovens by gently pressing the mobile phone key in the office.

14. Random switching between monitoring points, multiple mobile phones can be monitored at the same time
15. The alarm automatically sends a text message to the specified mobile phone and sends an e-mail to the designated e-mail address.
System network structure
basic skills
· Real-time alarm: When accidents occur on the monitored site, the mobile phone is alerted via mobile video.
· Active viewing: You can also check the situation of the monitoring site at any time and place.
· Online setting: You can set the monitoring device through the mobile phone, such as whether it is intrusion detection, power-off, image settings, etc.
· Multiple mobile phone support: When a mobile phone is unable to contact due to shutdown or network, it will alert other mobile phones.
· Server Storage: While alerting the mobile phone, high-resolution pictures are stored on the server for later use.
