What is a Scan Tool?
A scan tool is a Car Diagnostic Tool that can
exhibit a wide range of features. Scan tools typically include a code
reader, the ability to view and sort live data, and
some type of knowledge base. Professional scan tools include extensive
knowledge bases, diagnostic procedures, and sometimes even have built-in
scopes, multimeters, and other diagnostic tools.
In addition to reading and clearing codes, a scan
tool may be able to:
Although the ability to read and clear codes is
important, the additional functionality provided by a good scan tool can be
extremely helpful in diagnosing a problem. OBD-II vehicles, in particular, can
provide an enormous amount of data from a variety of different sensors, which
is why many scanners have the ability to store and play back live data. That
can allow you to test drive the vehicle and then view a recording of specific
sensor output readings during operation.
Unless you have relevant prior experience with the
specific problem that you`re dealing with, a good knowledge base can save you a
tremendous amount of time. Scanners that include troubleshooting information
and other tips will typically provide you with the definition of a code, the
potential faults that can lead to that code being set, and the tests that you
can do to track down the root cause of the problem.
While resources on the Internet don`t provide a
direct 1:1 replacement for the type of troubleshooting information you get with
a professional-grade scan tool, this is definitely a more affordable way to go.
A good consumer-grade scan tool (or an ELM327 scanner and the right
software) will get you on the right track, and you can supplement the
information that your tool provides with an online OBD-II code chart and
troubleshooting information. After you`ve tracked down the likely culprit,
tools like a multimeter and scope will help you determine whether or not
specific components are bad.
Pricing:
OBD-II code readers vary
in price.
They range from an
affordable price ($85) to many hundreds of dollars, or more.

Wireless monitoring is loved by more and more projects. How to solve these problems is the current situation of high engineering materials, high labor costs, and higher construction costs. Of course, the wireless video transmitter also has certain requirements for the transmission. If the scene environment appears to be blocked, the two sides need to be installed at the highest point to ensure that the transmitter and the receiver can directly look at the middle to ensure the open space. The two ends do not have hair to achieve high equipment can be used plus relay, wireless monitoring system can also be transmitted through the relay, that is, a launch, receive. Wireless digital microwave transmission is not afraid of obstruction, and the signal attenuation is small during transmission.
Advantages of Wireless Digital Surveillance System 1. Compared with traditional wired surveillance, wireless surveillance has a low overall cost. Wireless cabling, digging trenches, buried pipes, etc.; especially suitable for outdoor distances and renovated occasions; in many large-scale monitoring environments users are often limited due to geographical environment and work content, such as mountains, ports and open areas The special geographical environment brings great inconvenience to the wired network and wired transmission wiring projects. The construction period using the cable will be very long or even impossible. At this time, the use of wireless network can get rid of the shackles of cables. It has the advantages of short installation cycle, easy maintenance, strong expansion capability, and rapid cost recovery.
2. Flexible networking, digital wireless monitoring system has good scalability, plug and play, network managers can quickly add new monitoring points to the existing network, without laying networks for new transmissions, adding equipment, and easily Realize remote video surveillance.
3. After the wireless monitoring is installed, the maintenance cost is low in the post-maintenance. The maintenance of the wireless network is maintained by the network provider. The front-end equipment is a plug-and-play, maintenance-free system.
4, the wireless system can be powerful, flexible, fully digital video to facilitate the preservation and retrieval. According to the size of the storage space in the monitoring center, the size, quality and frequency of image acquisition, video data can be recorded for several hours to several months. The user can play, position, fast-discharge, and slow-play the recorded video data.
5, wireless through the signal at any time by monitoring personnel can be arbitrary control and observation of a camera to capture the real-time dynamic image scene, remote adjustment of the camera's focal length, aperture, depth of field, control PTZ all-round single-step fine-tuning or continuous fast adjustment. Wireless video transmission equipment, Shenzhen wireless video surveillance design and construction 6, wireless can achieve two-way transmission technology, multi-screen display, two-way conversation: the monitoring center display screen can be single-screen, multi-screen cycle display, can also be manually single-screen display switching, And two-way conversation or monitoring with the control point control room.
7. Remote monitoring, control and alarm can be performed wirelessly. At the same time, the scene status of the remote monitoring point can be automatically transmitted to the monitoring center with images and related information and automatically recorded.
8. Follow the globally unified technical standards and communication protocol TCP/IP for remote real-time monitoring across regions.
9. High security. The wireless network has security measures such as ESSID, MAC address filtering, and WEP encryption.
10, according to the requirements of customers, transfer data volume, analog quantity, switch quantity.
The entire wireless monitoring project according to the customer's requirements, we match the corresponding wireless video transmission equipment, so that it is scientific, reasonable, and cost-effective. 
Shenzhen Leian Technology Co., Ltd. wireless video transmission equipment, transmission effect is stable, the image is clear, strong anti-interference, plug and play, without any training to facilitate the use of customers.

What Can a Scan Tool Do?
Scan
tools are designed to interface with a car`s [on board diagnostic" system in
order to facilitate the diagnostic process.
In that
way, they are a lot like car code readers. They can be plugged into an OBD-I
or OBD-II socket, read and clear codes, and view data
readouts from various sensors. However, scan tools go beyond that basic
functionality.
The Importance of Scan Tool
Knowledge Bases:
In
addition to interfacing with the on board diagnostic system of a vehicle, the
other most important thing a scan tool can do is to provide you with some type
of knowledge base. The specific information contained in this type of knowledge
base varies from one scan tool manufacturer to another, but it`s almost
impossible to overstate the importance of good troubleshooting information.
Premium Scan Tool Features:
The
best scan tools essentially provide you with a [one stop shop" that includes
code and data reading functionality, advanced knowledge bases and troubleshooting
tips, and a built-in scope and other meters. Some of these tools, like the
professional-grade Snap-On MODIS, are prohibitively expensive, but they provide
you with all of the tools you need to identify, test, and diagnose failed
components.
Premium Scan Tool Alternatives:
Although
professional-grade scan tools can be prohibitively expensive, you can achieve
much of the same functionality without breaking the bank. Some of the things
you might want to have in your toolbox include:
Summarize the advantages of remote wireless monitoring system
Wireless monitoring, the use of wireless video transmission equipment can completely solve these problems, wireless remote video transmission equipment can not only solve the problem of transmission, but also can solve the PTZ to achieve the purpose of wireless control. Analog wireless monitoring can not be compared with wireless digital monitoring in both anti-jamming and carrier frequency. The wireless digital monitoring system adopts 5.8G frequency band, and can use one-to-many or one-to-one mode when there are more monitoring points. In the case of a later increase in points, expansion can be used.
