Payment
Q: What is the preferred payment method?
A: Our preferred method of payment is through PayPal and Credit/debit cards through PayPal.  You can also call our sales department to pay on the phone at (917) 677-4980.  If you wish to pay using a cashier's check, money order, or personal check we ask that you pay with U.S. funds only.  If paying through means other than Paypal please allow extra 2-3 business days for check clearing purposes.  In that event, we will withhold shipment of the product until the check clearing process is complete and we have the funds in our account.

Q: Do I have to have a PayPal account to send payments?
A: You do NOT need a PayPal account in order to send payments. Once you are on PayPal web page, you can choose appropriate button or link (such as PayPal's "Guest checkout" or checkout for not having PayPal account) to continue processing the payment. However, you need to make sure the your shipping matches your credit card/bank billing address.

Q: Why does my shipping address have to be confirmed by PayPal?
A: PayPal does not suggest merchant to ship anything to "unconfirmed" shipping address to prevent possible fraud. Common frauds include using stolen credit card to make purchase online but ship to a different address other than the credit card's billing address. If you provided an "unconfirmed" shipping address, you must contact us and provide a sound reason.

Q: How do I confirm an address?
A: There are three ways to confirm an address:
1. Add a credit card to your PayPal account. If your billing address is verified, your street address is automatically confirmed.
2. Apply and be approved for a PayPal Plus Credit Card, PayPal Buyer Credit, or an eBay MasterCard. If approved, the address on your application will be a confirmed address.
3. Alternate address confirmation. This process is available only for U.S. accounts, and it can take several days.
If an address is confirmed, the address status displays as Confirmed on payment receipts and the Transaction Details page.

Q: Why do I see half of the LED lights of the light bar are not on including one alley light (side light)?
A:  The connection might not be correct. Switch the two big plugs connecting to the control box, and it will fix the issue.

Technology of Rear View Camera System
Q: What is CCD?
A: CCD stands for charge-coupled device. CCD is a very sensitive electronic device that is revolutionizing astronomy in the 1990s. CCD, or charge-coupled device, is a very sensitive electronic device that acts as the camera's "electronic eye"—it is composed of silicon chips that are sensitive to light, changing detected photons of light into electronic signals that can then be used to make images. CCD sensors are popular for digital cameras and are generally associated with higher quality images. When a picture is taken, the CCD is struck by light coming through the camera's lens. Each of the thousands or millions of tiny pixels that make up the CCD convert this light into electrons. The number of electrons, usually described as the pixel's accumulated charge, is measured, then converted to a digital value.  People need CCD technology for rear view backup system especially while trying to safely reverse the vehicle in a rain or snow storm is a grainy.

Q: What is CMOS?
A: CMOS stands for complementary metal oxide semiconductor. Pronounced see-moss, CMOS is a widely used type of semiconductor. CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits. Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor. This makes them particularly attractive for use in battery powered devices, such as portable computers. Personal computers also contain a small amount of battery powered CMOS memory to hold the date, time, and system setup parameters. CMOS can provide full anti-blooming resistance, allows functionality on the chip (camera-on-the-chip), allows higher speeds (up to 60 MHz per output channel), allows accessing only parts of the image (ROI), and can be based on standard manufacturing processes.

Q: CMOS vs. CCD, which one is right for you?
A: CCD sensors are popular for digital cameras, and are generally associated with higher quality images. A CCD simply converts incoming light to electric charges and sends them to another part of the camera to be processed. This minimizes the noise that could be caused by complicated interactions with other components (thus keeps high image quality). CMOS sensors, on the other hand, perform more tasks. They are normally programmed to convert the electrical charges to digital data, detect edges and perform image processing. The multi-functional chip allows the camera to be much smaller, run on less power and create less thermal noise. CMOS sensors are also much cheaper to produce. However, all of these extra functions tend to create more overall noise (and lower image quality) because of resistance and interference. Recent advances have pushed the CMOS technology to produce much less noise while still taking advantage of the other benefits of the technology.

Q: Why does my CMOS camera always start out with red pictures?
A: Good question, however this is normal for CMOS image sensors and there is nothing wrong with your camera. The reason really comes from the fact that the light-sensitive pixels in the CMOS image sensor are actually more sensitive to infrared than visible light-especially the red-detecting pixels. Thus in environments that have a great amount of infrared such as a room illuminated by regular light bulbs, the image you get from your camera would start out very red. At this moment, the Auto Gain and Auto White Balance functions of your camera start to work. Auto Gain enables the camera to adjust up and down on the gain of R, G, and B color channels equally so the dark images are artificially brightened and bright images are artificially darkened. Auto White Balance adjusts the relative gains of R, G and B colors, so overall the image's total R, G, and B brightness are equal. After a few seconds, the reddish color becomes less and less, and the color of your image becomes normal.

Q: What Is TFT Technology and Why You Need It?
A: The monitor employs something called Thin-Film Transistor, or TFT. TFT is a special kind of field-effect transistor made by depositing thin films of a semiconductor active layer as well as the dielectric layer and metallic contacts over a supporting substrate. Liquid crystal displays, or LCD, typically use this process as a common substrate for TFT is glass. This differs from the conventional transistor where the semiconductor material typically is the substrate, such as a silicon wafer. The best known application of TFT is in TFT LCDs (thin film transistor liquid crystal display), a variant of LCD technology. Transistors are embedded within the panel itself, reducing crosstalk between pixels and improving image stability.
What does this all mean for the monitor we're talking about? It certainly is quite complicated. Well, all it means is that you're getting the latest technology that offers you a very light, thin viewing surface that's easily installed onto any standard factory installed rear view mirror. Plus, you get a great, sharp and clear picture quality, something that's important while operating your camera in heavy rain or snow, or any other inclement weather, for that matter.

Setup
Q: Can I connect my rear view camera directly to my vehicle power electric circuit?
A: Your camera works with 12V power supply and is designed to operate with constantly changing voltage levels (within normal range) produced by vehicles' battery and alternator. However, some vehicles have a very high momentary voltage at the vehicle starting time and the overload might cause damage to the camera. If that is the case for your vehicle, you will need to install a fuse/voltage regulator/etc. to protect your camera. Please consult professional vehicle audio/video equipment installers if needed.

Q: I didn't get a manual with the product I purchased, should I get one?
A: Most of our products are very simple to set up and come with the English manual in the package.  We do also provide the digital installation instructions when necessary. If you do need additional set up consultation or some help on connecting a specific component, please feel free to contact us and we have technical support staff to help.
