Our prices have a fair mark-up on our material/labor costs to provide profits for our company. We frankly cannot understand why specialty stores are selling rear-view systems at prices that are sometimes triple what you will pay here. The components in the Provix CCHT systems are of high quality and good value. We source all of our own components and complete final assembly on all systems at our location in New Lowell, Ontario Canada. The cameras and monitors provide a superior image and all camera systems have been tested in Canadian winter driving conditions. A full 6 month parts/labour warranty is included with each purchase. Volume discounts are available to retailers, OEM suppliers and anyone else who has a need to purchase more than 5 systems.

   a) Mount the camera.
   b) Run the cable under the vehicle and fasten with nylon wire ties.
   c) Push the cable through an existing cable hole in the floor to reach the interior.
   d) Mount the monitor using the sticky pad or screws.
   e) Plug the cables together (they only fit one way).
   f) Plug the power cord into your accessory or lighter socket.

Six IR lights will reach about 5 feet and twelve IR lights will go to 10 feet. The cameras are "light sensitive" and do not rely solely on the IR lights. When an object is very close to the camera, that object is blocking any ambient light. This is where the IR lights come into play. For rare situations where a camera is installed in a location where there are no tail lights, head lights or street lights, an independent Infrared flood lamp may be used. The models we carry have 69 IR lights and reach about 30 feet out.

Your home television is typically a CRT tube in a controlled light environment. The stations you watch are also in a controlled light environment when they are filmed. An LCD monitor is the same as what is used in laptop computers or on your cell phone. Glare and bright surrounding light will make any LCD screen hard to see. Adjustments with the brightness and contrast controls can compensate to a certain degree. The camera must constantly adjust for changes in lighting from shadows, sunlight, street lights and vehicle headlights. In answer to the question, NO .. outdoor rear vision systems are a completely different game.

Open the document link below for actual size scree shots of the monitors. Be sure to view them at 100% magnification for the proper size.

Sound would be important if you needed to hear a person behind the vehicle or trailer. Perhaps in the case where they are directing you when backing into a campsite.

Consumer feedback tells us that colour is preferred since it is easier to keep track of surrounding vehicles by their colour as opposed to make/model with the black/white camera. More customers choose colour cameras over black/white. A colour image is at its best on an overcast day.

They are the same system. The difference is how they are used. The term "back-up camera" implies that it would only be used for backing up the vehicle. A "rear-view" system is turned on all of the time while driving. The camera provides a much wider view than the vehicle rear-view mirror. Essentially, a "rear-view" system eliminates the need for a rear-view mirror.

This is the size of a camera sensor's active area. The smaller the dimension, the more "work" the camera will have to do to present a monitor sized picture. A 1/4" CCD will have to magnify the image more to show the image on the monitor. A 1/3" CCD will need less magnification to show the image on the monitor. A 1/3" CCD will cost more and have a better image. Both types are adequate for rear view systems.

Yes, CMOS technology has advanced over the past couple of years. Some manufacturers claim that their CMOS designs can compete directly with CCD camera. We know of two that are pretty close to CCD. These CMOS sensors may be known to some as "CCIQ" or "OV7949". OmniVision OmniPixel2™ OV7949 CMOS sensors are designed specifically for the automotive industry and can compete head-to-head with the competitive CCD market. The OV7949 image sensor is a high performance video camera with a small footprint and low power consumption. The OV7949 excels in low light conditions and can operate within a wide temperature range from -20C to +70C.

The "IPX" rating refers to how much water/weather the product can withstand. The IPX standards have set the following guidelines.

IPX-0: No special protection

IPX-1: Protected against falling water
 Equivalent to 3-5mm rainfall per minute for a duration of 10 minutes. Unit is placed in its normal operating position.

IPX-2: Protected against falling water when tilted up to 15 degrees
 Same as IPX-1 but unit is tested in 4 fixed positions - tilted 15 degrees in each direction from normal operating position.

IPX-3: Protected against spraying water
 Water spraying up to 60 degrees from vertical at 10 litres/min, (2.6 gpm), at a pressure of 80-100kN/m2, (11.6 to 14.5 psi), for 5 min.

IPX-4: Protected against splashing water
 Same as IPX-3 but water is sprayed at all angles.

IPX-5: Protected against water jets
 Water projected at all angles through a 6.3mm, (0.25 inch), nozzle at a flow rate of 12.5 litres/min, (3.3 gpm), at a pressure of 30kN/m2, (4.35 psi), for 3 minutes from a distance of 3 meters.

IPX-6: Protected against heavy seas
 Water projected at all angles through a 12.5mm, (0.5 inch), nozzle at a flow rate of 100 litres/min, (26.4 gpm), at a pressure of 100kN/m2, (14.5 psi), for 3 minutes from a distance of 3 meters.

IPX-7: Protected against water immersion
 Immersion for 30 minutes at a depth of 1 meter.

A typical highway lane is about 12 feet wide. To see the full width of a four lane highway you will want a viewing width of about 50 feet. For the distance behind you, you will want to see at least 10 car lenghts in order to make safe lane changes. If we use a car length of 10 feet for the calculation, you will want to see an area of 50 feet wide at 100 feet back.

The chart below shows the viewing width of various camera angles. As you can see, all camera angles will suffice for back-up or rear-view systems. The width at 5 feet back should be wider than the width of the vehicle. For example, a small car could use 60 degrees or more. A motor home needs at least 110 degrees in order to view an appropriate sized area behind.

The most important aspect of the camera angle is that the wider it is, the image appears more and more curved horizontally ("fish-eye"). A 42 degree lens will have the same "depth perception" as the human eye. A 110 degree lens will view the same width as the human eye. One is a trade off for the other. In the wide angle lenses, objects will actually be closer to you then they appear on screen. 

Yes, all of our "PR" series cameras are compatible with Pioneer Navigation Systems.
