Comparison Gazer CC2000-1Z0 vs Gazer CC155

Car models for which this camera is standard.

Reversing cameras can be created both in the form of universal devices and for specific car brands. The key advantage of the second option is ease of installation: the camera is designed for a specific “seat” (like a boot handle, license plate light, etc. — see “Installation type”) and does not require special tricks for installation. Yes, and connecting the "eye" to the on-board network and the screen, usually, is also not a problem. At the same time, such devices are usually produced for one car model, at best — for 3-4 similar models; installation on a "non-native" machine is often even more difficult than mounting a universal camera. It is also worth noting that the choice of standard cameras for each particular machine is rather small — definitely less than the range of universal models. Therefore, there is a high probability that this type of camera, which is easy to install, will not be suitable for some of the parameters (for example, resolution).

Now on the market for such car brands, reversing cameras: Audi, BMW, Chevrolet, Chrysler, Citroen, Dodge, Fiat, Ford, Honda, ...>Hyundai, Jeep, KIA, Land Rover, Lexus, Mazda, Mercedes-Benz, Mitsubishi, Nissan, Opel, Peugeot, Porsche, Renault, Seat, Skoda, Subaru, Suzuki, SsangYong, Toyota, Volkswagen, Volvo.

Standard installation method and location provided for by the camera design.

- Universal. This installation method can be conventionally called “external” - the camera is placed on a stand that is screwed to a particular surface, and the body is completely located outside. This option is generally universal and can be used regardless of the car brand, although there are standard cameras (see below) with this installation.

- Mortise. Cameras installed in specially made sockets for them. They are usually round in shape, and for installation it is enough to drill a hole of the appropriate size in the car body. Also, as a rule, they are universal.

— Screw. Cameras designed to be installed using a screw mount (hence the name). They are quite simple and easy to install - just make a hole for a screw in the body, and the required hole size is noticeably smaller than that of mortise models. Most often they are universal.

— License plate frame. Devices that are frames for license plates with built-in rear view cameras. They are convenient because they do not require special installation work - the structure is simply installed instead of the standard frame, on the same fastenings. At the same time, it is worth considering that frames for numbers can have different formats and, accordingly, the size and c...onfiguration of fasteners; This point must be clarified before purchasing.

— In the license plate light. Cameras mounted in the license plate light. They often include not only a camera, but also a lamp to illuminate the license plates. License plate lamps on different cars have different designs; accordingly, models of this type are made mostly standard (see below).

- In the trunk handle. Models that consist of a trunk handle with a camera installed in it and are mounted instead of the complete handle. They are made only by regular ones (see below).

- In the emblem. Models of this type can represent either separate cameras built into the “nameplate” or emblems supplemented with cameras and installed instead of the factory emblem. By definition, they are only regular (see below).

— In the radiator grille. In the vast majority of cars, the engine and, accordingly, the radiator are located at the front; Accordingly, this option is typical for forward-looking cameras (see “View type”). Most of these models are standard (see below).

- At the stop sign. The optics are made in the form of a brake light. As a rule, such cameras are made for a specific make and model of car. The device itself is installed in place of one of the standard brake light headlights (right, left or center). At the same time, during the installation process there is no need to make holes in the body elements or turn off the license plate light. The camera in the brake light body does not violate the integrity of the design of the stern, laconically blending into the image of the exterior.

The physical size of the photosensitive element of a camera. It is usually measured diagonally and is indicated in inches — more precisely, fractional parts of an inch. The larger the sensor, the larger the size of each individual dot (pixel) on it, the more light enters each pixel, and the easier it is to ensure high image quality with a minimum of noise (especially when it comes to shooting at dusk). However you need to remember that only matrices of the same type and resolution can be compared with each other in size. And a large sensor is not always a guarantee of quality — a lot depends on the rest of the hardware of the camera, the quality of its installation and other factors. However, the large size of the sensor usually indicates a high class camera.

The resolution of the frame taken by the camera in video mode, in pixels — in other words, the size of the picture in dots horizontally (first digit) and vertically (second digit). It should be taken into account here that in the case of reversing cameras, the recording in pixels describes only the frame on the camera matrix itself; to describe the "picture" coming to the connected screen, the designation in television lines (TVL) is used. This is due to the fact that the video signal is transmitted in an analogue format; See Video Resolution below for more on all of this. Here we note that with the same resolution in TVL and the same viewing angles, a camera with a higher resolution in pixels will produce a clearer, more detailed image. But HD reversing cameras, and even more so Full HD units.

Although modern electronics are dominated by digital standards, car reversing cameras still use an analogue signal transmission format. This is due to compatibility requirements: such video allows you to use fairly simple screens. And although its quality loses to digital, it is quite enough for most of the tasks facing this class of auto electronics.

An analogue video signal has a size in horizontal and vertical dots. But since the number of vertical dots has a strictly defined number of 625 (in the PAL and NTSC colour system), resolution is usually indicated only by the number of horizontal dots (TV lines).

In fact, this parameter describes the quality of the image that is displayed directly on the screen connected to the camera. There are models with a value of 480, 500, 520, 540, 560 TVL and even higher resolution in TVL. This is important for models with wide viewing angles (see below). On the other hand, in order to use all the features of a camera with numerous TV lines, a screen corresponding to these features is also required; For more details on compatibility with the screen, see specialized sources.

The viewing angle characterizes how wide the area of space is captured by the camera lens: the larger they are, the wider the field of view, the more space is in the frame. In most modern models, it varies from 120° to 170°; this allows good visibility of almost the entire rear hemisphere. There are 180° cameras and even more; they will come in handy if visibility is important to you not only from behind, but also on the sides. But note that some manufacturers indicate the angle horizontally, while others — diagonally.

At the same time, it does not always make sense to chase wide angles. Note that the larger the viewing angle, the more distant, reduced the image looks, the more distortion occurs at its edges. In addition, wide viewing angles require high resolution, which accordingly affects the price of the camera; if the resolution is low, the "picture" may look blurry and small details will be lost on it.

The colour system refers to the format in which colour information is transmitted in an analogue video signal. In modern reversing cameras, the European PAL system or the American NTSC are most often used. It makes no sense to describe them in detail — suffice it to say that for the normal operation of the camera you need a radio tape recorder (or other device with a screen on which the image is displayed) with support for the same colour system. However, incompatibility in this parameter is not fatal — with such a connection, the image will only turn from colour to black and white (in extreme cases, its overall quality will slightly deteriorate).

The format for displaying the image on the connected screen. For each type of review (see above), there is a different option that is optimal.

— Direct. The traditional way of displaying an image: the user sees on the screen the same thing that the camera lens "sees" in front of him, with the same arrangement of the details of the situation. Simply put, if some object is located to the left of the centre of the camera's field of view, it will also be visible on the screen on the left side. All front view cameras work this way.

— Mirror. In this mode, an image is displayed on the screen that is “mirrored” horizontally — roughly speaking, one in which “left” and “right” are reversed: an object to the left of the camera lens will be visible on the right side of the screen, and vice versa. All cameras with a rear view type work in a similar way. This is due to the fact that in an ordinary rear-view mirror the driver sees exactly the picture inverted horizontally; therefore, in order for the sides of the picture on the screen to correspond to the usual view in the mirror, the image coming from the camera has to be “mirrored”.

— Direct / mirror. Cameras capable of operating in any of the picture modes described above. Usually, these are universal models (see “Installation”), which formally refer to the rear view type in our catalog (see above), but also allow front view.
