Buyer beware of suspicious limitations
Reviewed in the United States on February 23, 2020
Disappointed by privacy and limitations; won't buy again. Was hopeful and tempted by the wide angle, so bought 2. Ugh. Although 1080p camera image and wide 110-degree field of view are great, the HM203 YCC365PLUS camera is tightly locked down and restricted to a seemingly-unsafe cloud application, with a few red flags. Very limited freedom, and suspicious cloaking around connectivity.
Rather than use a common web portal approach to configuration, HeimVision HM203 YCC365 PLUS camera forces access only through their Android app, which btw also wants LOCATION access. (Beware of proprietary software and possible backdoor exploit vulnerabilities. You risk showing up on live webcam feeds around the globe. Comfortable with that?)
A computerized voice complains occasionally if you tell your router to block internet access (a firewall is HIGHLY recommended for your privacy, but this cam doesn't like that), so you're truly stuck while the OS ensures you are online and exposed to the world.
Many cams ship with proprietary or closed-access configurations (e.g. the popular Wyze models, Ring, etc), but HM203 went above and beyond to mask entry and disable http/ftp/ssh. And they don't like your firewall. (The frequent tcp/udp network transmissions resolve to alibaba and alicloud.)
Although I was able to root into the camera's linux-based OS (powered by HiSilicon hi3518e chipset I believe), I found it too much work to get around the obvious attempt by the manufacturer to prevent any configurability away from their YCC365 app. Customized kernel... hints of nefarious determination. Why so locked down? What if we want another firmware? What if we wish to flash a better OS? I guarantee you won't find utilities or firmware on their website - just their suspect apk, and many others complaining about the locked access.
Too much hassle for the price.
I advise buyers to look elsewhere, unless the Chinese manufacturer agrees to the following: 1.) open up unrestricted web portal access 2.) unlock their read-only Linux based operating system 3.) release buyers from forced-use of an Android apk that wants far too much information (location, network detail, anything else on your phone.)
Otherwise, you have no idea who is watching your cam, and from where.
Save yourself the hassle. I'm going back to Wyze v2, and will enhance it with xiaomi dafang. So much better.
