Waterproof GPS Tracker D22-4G

Make sure the command you set according to the below frequent issue. The SIM card of the Tracker supports the GPRS function. Send the APN set command SMS to configure the application and send SMS to tracker to trigger it reply back information. Set The GPRS signal interval the port number you set for the tracker have its program. If your router is dynamic IP addressing, don not forget to resend APN set command SMS when the IP address is changed. check out the IP address for PC server When you login your router, you will get your IP address in the login box. Also there is some website or software could help you to check your own IP address. setup the port number Port number is a random number which is setup by the end user, please make sure this port is not occupied by other software otherwise the PC server software will shut down automatically. In order to avoid the conflict, we suggest you setup the port number bigger than 6000. check out the APN name of your local telecommunication provider If the GPRS configuration has been wrongly set, the device will spend long time to repeatedly engage at connecting with IP address, this will cause the outing SMS delayed.

Currently, GPS tracker Systems is using the Google mapping interface for maps, and partners for the street level data that is displayed on the maps. It is able to use any mapping interface and can customize mapping solutions based on the specific requests or needs.

Wireless Networks - GSM/GPRS For Real-time GPS tracking, the wireless network is used to communicate the GPS data from the vehicle/asset, so location, speed and stop times can be viewed in Real-time. Think in terms of how mobile phones work. There are two types used; (1) Digital Cellular and (2) Satellite. Obviously, digital cellular is more popular due to cost. This is the same with communicating real-time GPS data for vehicle tracking. Wireless Networks: Cellular vs. Satellite Due to the facts that (1) hardware is less expensive (2) monthly service fees are less expensive (3) superior network reliability; a digital cellular-based system is the best way to go for the vast majority of companies that want to use a real-time system for nearly any type of tracking. Digital Wireless Networks If you are looking to purchase a 1st tier GPS tracking system, then you should be looking for a system that operates on a 1st tier digital wireless network. All of the 1st tier wireless communications companies is the market have moved to digital wireless networks. There are two types of types of digital wireless protocols that the major communication companies have utilized for the build-out of their wireless networks: GSM/GPRS CDMA (1xrt) There is an on-going debate as to which of these protocols is superior for cell phones, but for live data feeds for devices used for GPS tracking, mobile email, and wireless forms, the "always on" technology of GPRS is clearly superior. GPS devices that use this network are "pay as you go" type devices. One should only consider using GPS devices on these networks for applications where only a few location records per day are required. GPS devices that use these networks should never be considered for fleet management applications due to the fact that reporting vehicle activity for a sound fleet management system requires between 1000-3000 records generated per month. The cost of this many records on these networks would be far above the flat fee you would pay with a superior, digital GSM/GPRS.
