These work great, but the app is a little confusing.

I was looking for something I could install myself with no need to pay someone else to do it, and that I could keep all the recordings in a hard drive instead of paying cloud storage.

But I got more than that. I was able to install it easily and I get up to 40 days of video storage on the 3TB hard drive.

I really like that you can customize the alerts, so you can choose at what time you want to receive alerts of specific cameras.

Image is very clear during the day and at night.

Signal suffers a little bit when windy but is expected since these are wireless, anyway I got some additional antenas and problem is solved.

Finally, the app eseecloud is great, allows me to watch live my cameras when I'm not at home, I get my notifications at the moment and what I like the most is that I get a preview of the notification in my Apple Watch.

We bought the 8 camera with audio set in Oct. 2021. In June 2022, the camera feed just stopped. No warning of issues. All feed just stopped. We tried to restart, reboot, unplug/replug, etc. Still nothing. It seemed obvious to me the computer wasn't working. On a Sunday at 6PM EST, we called the number on the equipment. A recording in Chinese played, followed by a recording in English stating the phone we were calling was turned off. So we emailed the email address on the equipment. We got a reply in less than 2 hours. We saw then that there is a language hurdle and a significant time zone difference. It took 3 weeks, several emails with Hiseeu, a lot of searching through manuals and YT videos, one phone call from Hiseeu, a new NVR, a new HDD (the NVR is the black box and the HDD is the hard drive), and help from our neighbor who has the same system, but we finally got everything operational again. The language and time-zone difference are significant factors in accessing technical support. BUT if you're patient and willing to stick with it, you WILL get help. We are impressed with the system and the support. Both are reliable. Just don't expect immediate help in English and be prepared to fill-in a lot of info for yourself because of it. Also, for anybody who has to replace their HDD here's the steps we wish had been given from the start. GETTING A NEW HDD MEANS YOU'RE BASICALLY STARTING ALL OVER. YOU WILL HAVE TO TAKE ALL THE CAMERAS DOWN AND BRING THEM INSIDE TO BE NEAR THE NVR IN ORDER TO SYNC THEM TO THE NEW HDD. PLAN A DAY WITH GOOD WEATHER AND WHEN YOU CAN DO THIS WITHOUT A TIME PRESSURE. IT IS A STRAIGHTFORWARD PROCESS BUT WILL REQUIRE TOOLS, A LADDER, PATIENCE AND ABOUT 2-3 HOURS.
1. Watch any of the several videos from Hiseeu on how to replace the HDD (they will send you links).
2. You will need to sync all of your cameras with the new HDD.
3. The cameras use a wireless connection to communicate with the HDD.
4. To sync them, each camera must be taken down, brought inside and be near the NVR for the signal to initially connect. THIS IS THE STEP NO ONE AND NOTHING TOLD US BUT MUST BE DONE FOR THE SYSTEM TO WORK.
5. Plug each camera in. It's easiest if you do them all at the same time.
6. Right click mouse.
7. Click Video Manage.
8. Click Delete All. (This deletes the current camera signal that was between the cameras and the old HDD. You must do this in order for the new HDD to get the cameras' signals instead.)
9. You should now see "No Video Source"
10. Click Match Code
11. One by one, each camera will connect.
12. If they don't, click the reset button on any camera that isn't connecting. You may need to do this several times.
13. Once they're connected, you can reinstall each camera.
14. If any cameras don't connect, contact Hiseeu for additional support.

Overall these are good cameras, some how one of my camera now give pink or purple video and I am not sure why. Camera is facing east so may be early morning sun light damaged it or may be something work with that particular camera. Others are good and I am happy with camera pic and video quality. Night is really good.

I bought the 8 channel NVR and wireless cameras (+ 4 PTZ cameras) back in February 2022. Overall, most of the components has done outstandingly well. The picture quality is great for its class and the ability to remotely monitor my property through the app has been invaluable, as I travel a lot. I work with security systems all over the state, and actually have access to high grade commercial video systems. However, after an enormous amount of research, I decided to go with Hiseeu because first and foremost it had to be wireless (to my knowledge there are no stand alone high-end commercial grade video systems that are wireless). Secondly, I was not going to settle for a brand that requires their services for the equipment to even work, forcing you to pay a monthly subscription to monitor your property. I believe Hiseeu offers a subscription cloud as an option (but it's not required, which is a major plus in my book) and they don't charge for the app which was another major plus and a deciding factor for me. But most importantly, in all this time, I've only had one issue recently, but they were very honorable and resolved the matter with integrity and fairness, and in today's world that's incredibly impressive!... I couldn't be happier!!! Thank You.
