For the money, excellent. The nvr software is expensive, the same as the srihome nv004 (189.95 from eshop), which pleasantly impressed me. Honest camera and recorder construction (I will return with a review on the quality of the camera plastics). In a review I read somewhere that the camera only adjusts up and down. Wrong! On the camera where the arm starts, there are two cross screws that you loosen enough and move the camera to the desired tilt right and left, and then tighten the screws to stabilize it. The software on android is tseye, which I also found easy and fast. Overall, I think it's worth the money. It includes a mouse but not an hdmi or vga cable. **After three months of operation, the external cameras have not had any issues or changed color like the Srihome ones (from white to yellow). The recorder is quite good without any glitches or anything. In one word, a good purchase for this money!

It has a very narrow viewing angle, so in order to cover a bedroom ceiling of 3+++ meters, two cameras are needed. Additionally, the arm does not have the ability to look where you want; if the camera is placed in a fixed position, it only looks straight and downwards.

For now, I am satisfied with the performance of the cameras. It has some interruptions in video recording. The resolution is satisfactory for their price.

For the money, it is good. It has easy installation and works fine. The cameras are not 2.8 mm so the image doesn't have a wide angle, so they need some distance to show a large area

Very good for its price, first time in the 4 years that I do installations I chose wireless and they impressed me both with their image and how much work you can save in small installations where you don't have a signal issue and you don't have to spend a day running cables. I hope they will withstand over time. Also, I didn't search to see if you can add another wireless camera besides the ones included in the package, from another brand, meaning via IP. If someone knows if it's possible, please mention it for the next person who will choose them

It is not the latest technology nor does it have any expensive build quality, we knew that before buying it. It has minor playback and tuning issues (it resets options on its own).
Good value for money.

Good image analysis, easy and fast installation and connectivity, satisfactory range for the furthest camera at 25-30m, works with a mobile application, requires the purchase of a hard drive!

The signal has no problem. The issue is that it has no sound and no motion detector. The image quality during the day is very good for its price, as well as during the night.

It is not easy to install, often experiences a cyclic loss of image, meaning that the disconnection is transferred from window to window. I couldn't enter the pin code, the field is gray as if it has retained settings from another user, I'm not sure. Also, very often, two cameras that see the same point, one sees the present and the other will show me the same event after 20 seconds or more, or not at all.

I was impressed by how easily and quickly it detected the cameras. The cameras were placed about 30-40 meters away from the recorder and within seconds, without doing anything, I had an image on the screen. Of course, there is no need for WiFi (internet) for the cameras to connect to the recorder. Only if you want to have the image on your mobile, then it needs to be connected to the router.
The build quality is average.
The image quality is mediocre to good.
Nighttime shots are good.
The image is not wide-angle.

Easy installation.
The quality of the central unit is somewhat low (the antennas came off, but were reattached with glue).
The cameras are of high quality, but I would like them to be a little more wide-angle.
A decent product.

It does exactly what it describes in the sales brochure. A reliable product with good image on the mobile phone. I recommend it as a good purchase.

Very good construction and good image quality.
Easy-to-use menu.
Everything you need for installation is included in the package (except the hard drive, of course)
