considering it's a product from a community country, why would they bother with proprietary stuff, right? Well. when I asked (in the Xiaomi RTSP hack thread), you recommended this model, but I you know, sometimes you don't know what someone's warning means until after you get the problem, so I got the device thinking it would just use HTML5 you know. Like the HW0026 before, the HW0049 connected straight away as an Onvif 2.1 device to my Synology Surveillance Station with audio support, and Pan & Tilt control.
The camera uses the cgi instruction set from HiSillicon which SDK is documented in various places.
While it's not only used for trojans, the port 32100 has a bad reputation. I've set my firewall to drop (and log) any outbound communication attempt from the address pool dedicated to my cameras.
Update (): I have noticed that, despite that I turned off the UPnP option, the camera is still trying to chat with the outside world something I don't see with the older HW0026 (also an older firmware). Strangely, this section is now missing from the menu of the current web interface version, but the page can be called directly: /web/upnp_men.html I always forbid that kind of traffic outside my LAN ( as much as I can), and also disable the UPnP feature on the camera when possible. While the HW0049 offers the P2P convenience, it is not a requirement to use the camera fully. The recordings on the Micro-SD card can be played back from the web interface via the "Intelligent online playback" /backplay.html (ActiveX only) or downloaded from /sd/
They're almost on feature par with the exception of motion detection areas, and video masks (to hide some parts of the picture) which require ActiveX (IE). It's worth noting that the browser interface works in IE with ActiveX, but also in Chrome or Firefox with the Flash Player plug-in (hence the use of the RTMP protocol).
The camera offers 2 user interfaces (3 if you count the PC program but it's not worth it): The neat smartphone app E-View7 ( Android, iOS ), and the embedded web interface, which offers s ome advanced options not found E-View7, like the ports assignment, or the Onvif parameters.
