I compared this camera to the JORTAN 8167QJ and JORTAN PR16-8170QJ. All three have a similar image quality, which is not HD as they claim. However, it is satisfactory for night vision up to 10 meters. It operates with the YOOSEE application, which is not user-friendly compared to IPC360Pro, as it is in Greek but requires you to think in Chinese to understand it, due to the translation it has undergone (see my reviews for the other two cameras by searching their names). When the camera is connected to Wi-Fi, there is no indicator LED for operation. The 8 IR LEDs turn on when you access the application to view the image. When the "alarm" is activated, the LEDs remain permanently on whether you are viewing the image or not. However, in order to receive motion detection notifications, you must have both the "alarm" and motion detection activated, regardless of whether you are viewing the image or not. In the dark, when motion is detected and the alarm is activated, the 8 illumination LEDs automatically turn on, which are quite powerful. You can also manually turn them on whenever you want through the application. Their brightness and duration cannot be adjusted. With motion detection, the camera follows the target if you have already set it up. This works much faster and more accurately during the day compared to night. Only one registered user-viewer can access the camera through the application at a time. This is done to prevent unauthorized individuals from stealing images. However, another person can register in the application with a different email and password, and the original user can share the camera with them and grant them viewing rights. When you connect to the camera through Wi-Fi that it is connected to (not its original one, but for example, your home's Wi-Fi), you can see the image and have a faster response to its movements compared to when you monitor it through a different Wi-Fi. You can also view for as long as you want, unlike the IPC360Pro application. The tests were conducted with two different Wi-Fi networks, as well as mobile data, trying all combinations with the three cameras in the same position and monitoring the Wi-Fi signal for any momentary disconnection. YOOSEE provides a link for you to view the image on a computer. I forgot to mention that none of the three cameras have zoom capabilities through their applications. You can only zoom in on the image on your mobile device, as you would for a photo. When you do this, you will notice that the image does not remain clear like the original, but becomes pixelated. After testing them for several days, today (2-6-22) I decided to insert a memory card. I inserted an 8GB HC C4 card, and after a few seconds, it caught fire. It was so hot that I couldn't touch it. I disconnected the power and after removing the 8GB card and letting the camera cool down for a while, I initially inserted a 2GB card, and it worked normally. Then I inserted a 4GB HC C4 card, and it also worked fine without overheating. I believe that the camera does not support cards larger than 4GB, despite claiming compatibility with up to 64GB. Additionally, in this camera, the recording settings do not allow you to select the video playback quality of the card, as can be done with the JORTAN PR16-8170QJ. That's all for now. 01/11/22. I would like to add that the camera's movement is step-by-step, even if you hold down one of the movement buttons, compared to the PR16-JORTAN-8170QJ, which has continuous movement. This means that the GW-D16A stops at specific points of the route, while the PR16-JORTAN-8170QJ stops wherever you want. Of course, this difference cannot be considered a "problem".
8/01/23. I would like to inform you that the GW-D16A displayed image blur, which is probably due to the humidity in the environment. During the day, it is not so noticeable - annoying, but at night, due to the use of infrared, the image is slightly blurry in the areas with humidity. In this aspect, the PR16 is better. Both are protected from direct rain and direct exposure to the sun.
12/04/2023. I am coming back to inform you about something I noticed in the applications. Specifically, I recently purchased a camera that has an E27 socket and screws into a corresponding light fixture. It also works with the Yoosee application. It easily passed to the application on my mobile phone, and I can see all the cameras. The problem is with the CMS client application on the computer. This camera cannot be added there. You have to download another Yoosee application to view it. As I noticed, all the cameras have an eight-digit code, while the one that looks like a light bulb (with the E27 socket) has a ten-digit code. Yoosee guides you on the website on which application to install on the computer. I am just writing this for information.
