For the low price good performance

With the operation of the system, I am satisfied. The video and audio transmission are very good. Operation is intuitive.
The non-adjustable ring tone is pleasant. DingDong. You can adjust this volume. The loudest level it should be with us already.

Criticism I practice at the installation of the system.
When you have to pre-drill outstation 4 holes. In the manual is that one can use for this purpose the frame as a template. This is only conditionally. The framework can be the inner dimension Mark. Then you have to laboriously count down the centimeter to the holes and draw. This was very time consuming.
Through the openings of the outdoor unit, it was not possible to draw the holes. But the holes were too deep and too narrow. Since no pin fits in. With a nail is not much in clinker.
After tightening there is no way to correct something. Neither to the right nor to the left. If in doubt the system is crooked or warped.

Also in the indoor unit, which was easier to install, you can move anything right or left after drilling of the two holes. There would have been no problem to install in the bracket oblong holes to compensate for small errors.

Behind the indoor unit only fit the cable. Possibly existing luster terminals you do not get under there. So you have to twirl it all together and use the good old tape.
This too is far from a well thought out design.

The eye of the video camera can not vary it. It fit with us as well that way.

The first plant that I had ordered from Amazon, showed many coarse vertical scratches on the Kunsstoffabdeckung the camera. As drawn with a ruler.
The ordered second plant, also had these shortcomings. However, these were not so serious. This system I have kept. This is something I do not understand. Especially in the area of ​​the camera lens should not use scratched plastics. There was not even a top transport protector. The uniform scratches were caused but in my estimation at the production stage.

When I unpacked the transformer, shudder. It is an outlet transformer made in China. It is extremely light.
How am I supposed to accommodate because in my fuse box? There previously was doing a very good Huttraffo his work.
I had already tinkered from an extension cord a picture for this Cheap transformer.
My friend who is professional, but could use the existing transformer for the plant. The use of low-cost transformers he dissuaded me.

Because ultimately the system does its job very well and they had cost only 95, I admit, despite the significant design defects and inferior acting transformers 4 stars.
However, the stated list price is the facility not worth it.
