The wireless radar detectors are the detectors which are not using the wire or cable installation to power the unit. It uses the batteries to power the unit. Some products offer you the rechargeable function that enables you to charge the used up battery. You will not need to buy the fresh batteries when the batteries are running out.
The cordless radar detector will give you some advantages which will benefit you. The main advantage is the portability. When using this product, you will get more flexibility in your car. Even, some products can fit to your shirt pocket. Have more free area in your car area. You will not need cable or disorganized wiring inside your cars. If you hire the car, this device is the finest solution.
However, you may also have some disadvantages like the running batteries. If your devices have the lower power, then they will have the lower sensitivity. It will be possible for you to build the cordless radar detectors which can match the cigarette lighter powered model. But it will consume much power from the batteries before you have any opportunity to bump into the speed trap.
You have to know that there is the trade off between the performance or the sensitivity and the life of the batteries. To converse the battery life, the radar detector without wiring installation has the duty cycle. It means, the detector will shut down for a moment in order to preserve the power. When using these detectors, you will see that the devices turn on and off. The shut down period itself is about milliseconds. Due to the short time, you will hardly recognize that the devices actually turn on and off. This technique has the affect to the detector performance that is lowering the sensitivity of the wireless radar detectors.
The worst effect is experienced by the Ka band which has the wide frequencies range to scan. It also takes the power of the batteries in the quiet big amount to scan before compromising the duty cycles of the wireless. It can be said each detector which you choose will bring disadvantages and advantages. You need to trade the battery life for the awareness and the operation.
Other advantages from this device are the light in weight and the high portability. Find the most convenient spot to place the detector in your car. You will find that it might be easier to arrange the car. Do not have to deal with untidy wiring installation. You will not need any electricity in powering the device since the device depends on battery for the power. Look at your battery every 3 weeks or certain period to make sure whether the battery is exhausted or not. It can be dangerous when the battery is drained. Your detector will not be able to work.
