driving at night several times higher than during the day, so the traffic recorder night vision capability is optional, an important consideration in the project. The lithography X3 built-in low-light sensitive sensor, 6 ultra brightness LED fill light on both sides of the camera, videotaping better quality images even in the dark.
Second measure: see Resolution
Traffic recorder riders urgent need is at the time of the accident, record the truth, to seek corroboration. So the clarity of the image to the main. Like collision like Guaceng accident will be responsible for, the easiest buck-passing, imagine if the lack of clarity traffic recorder, can not see the subtle images of the accident instantly that traffic recorder did not play its due role as tasteless. The lithography X3 has the quality of high-definition video recording function, 720P HD resolution, front license plates, road signs visible. In the event of unforeseen circumstances, the subtle images easily burn
Third measure: check HDMI HD video output port
Traffic recorder designs focus on lightweight overall small, the screen is relatively small, but the event of a traffic accident, to see the screen fixed censure from visual limitations. HDMI HD video output function perfectly circumvention can directly output HD video to Full HD TV or HD display on the big screen, complete embodiment definition picture quality, to restore the truth.
Fourth trick: inspection detail settings
As may court the video evidence, the details of course very important, Newman lithography X3 videotaping images have a time and date stamp. Such as evidence in a traffic accident, more persuasive quickly and accurately, but also facilitate the traffic police handling the accident, to quickly leave the scene. Of course, there are some other features intimate example: when webcam or U disk, also can block the momentary needs; whether the built-in lithium battery out of the car charger alone use, easy to come up with exterior cameras scenery along the way ... ...
In addition to the above key four strokes, loop recording, motion detection, storage traffic recorder functions must not be underestimated, faithful car experience some will be able to spot a good or bad choice carefully.

How do GPS Jammers Operate
When you see information on GPS Jammers, you may wonder what a GPS jammer is and what potential applications it may have.
GPS Jammers
Before explaining the how and what of GPS jammers it is best to explain how GPS works. GPS stands for Global Positioning System. It is used by individuals, commercial entities and the military, mostly for navigational purposes. GPS uses a system of satellites that orbit the earth and send radio signals. The GPS satellites work with a GPS receiver to determine positioning via triangulation. GPS can be found (and hence GPS jammers can be effective against) individual handheld units, car navigational and positioning systems, and boat navigational and positioning systems.
GPS operates using triangulation, which is a method in which three separate points are measured to calculate location. In a car's navigation system, the car's location is measured by three specific satellites orbiting the earth. Using triangulation, GPS can deliver the location to the receiver within inches of its exact location. It is important to note that GPS radio signals use a specific frequency. There are actually two major frequencies that GPS works on: one is for public, non-military use at 1575.42 MHz and one that is used solely for the US military at 1227.6 MHz. Because GPS is nothing more than radio waves, these waves can be jammed using a GPS Jammer, though technical devices and expertise are needed for that purpose.
While GPS jammers have been created (specifically by the government, military organizations and spy or privacy gadget companies), most civilians do not have the technical capabilities to create their own home made device. It is much more difficult than just blocking a radio signal with basic radio interference.
Most GPS jammers are built for military uses, for instance, to confuse the enemy on where their exact location is or where the enemies GPS guided missiles or bombs will fall. However, there are a few civilian uses for jamming GPS signals including the ability to conceal oneself or one's vehicle in the case that it is being tracked by a GPS receiver. A practical application of GPS jammer use by civilians would be a salesperson that would buy a GPS jammer. The salesperson may want to have lunch outside their territory, or run home for a forgotten item, without having to do a lot of explaining due to GPS tracking on their vehicle. Most GPS jammers have a range of up to 10 meters, which will cover even the largest of vehicles.

What's the car Parking sensors
Parking sensors are proximity sensors for road vehicles which can alert the driver to unseen obstacles during parking manoeuvres. The whole system is sometimes referred to as Park Distance Control (PDC).
Parking sensors generally fall into two categories.
1. Electromagnetic parking sensors
These rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once detected the obstacle, if the vehicle momentarily stops on its approach, the sensor continues to give signal of presence of the obstacle. If the vehicle then resumes its manoeuvre the alarm signal becomes more and more impressive as the obstacle approaches. Electromagnetic parking sensors are often sold as not requiring any holes to be drilled offering a unique design that discretely mounts on the inner side of the bumper preserving the 'new factory look' of your vehicle
2. Ultrasonic parking sensors
The rest of this posting refers to ultrasonic parking sensors only.
The ultrasonic sensors are currently available in several brands of cars, with a variety of brand names such as Parktronic and Parking Aid. Some systems are also available as additional upgrade kits for later installation.
Parking sensor systems use ultrasonic proximity detectors embedded in the front and/or rear bumpers, to measure the distances to nearby objects at low level. The sensors measure the time taken for each sound pulse to be reflected back to the receiver.
Depending on the speed of the vehicle and the distance to the obstacle, the system will warn the driver by visual and/or audible means about the risk of collision. The feedback to the driver will generally indicate the direction and proximity of the obstacle.
Sensors are usually fitted to the rear of a vehicle but may also may be fitted to the front.
Rear sensors are activated when reverse gear is selected and then deactivated as soon as any other gear or neutral is selected.
Front sensors are generally activated by pressing a button and then automatically deactivated when the vehicle exceeds a certain speed, this is to avoid nuisance warnings in slow moving traffic.
