For $43 (delivered) I recently purchased a small, outdoor 720P ONVIF camera from China via eBay. It took a little over a month to arrive, but it did arrive. See attached screen capture of its eBay listing page. It is quite small - the camera body measures 3.75x2.75x2.75 inches. The image quality is quite nice - see the attachment.
It, like most Chinese IP-Cameras is MicroSoft Internet Explorer (IE) centric, meaning that full utility is achieved only by using IE with the camera's downloaded ActiveX installed. While I did test the camera in a Windows XP VirtualBox, I use Linux, not Microsoft products. Consequentially, this camera is sub-par for non-Microsoft use. Nonetheless, it is useful. I mostly monitor my cameras on either my Android phone or tablet and I can configure it for good operation on Android. On the Android, my preferred app is "IP Cam Viewer" by Robert Chou. It is excellent for my MJPEG and pretty good for ONVIF cameras. The other Android app that I use is just for ONVIF cameras - "Onvifer" by IPCentcom. Its image quality for ONVIF is excellent. On my desktop, I use VLC for image viewing.
The camera that I received has a wide-angle 3.6mm lens. I think that I would prefer the 6mm or 8mm as there is some edge distortion with the 3.6mm lens.
The camera's factory is Shenzhen Hong Jing Tian Electronics. The manufacturer is listed as "IPCAM" and the model as "C6F0SeZ3N0P0L0". The WiFI card identifies itself as Shenzen Oqemray Technology. The Shenzen Oqemray Technology website only lists peripherals like WiFi cards on their website.
The IP address arrives fixed at "192.168.1.88", although DHCP can be activated, if desired.
The eBay seller that I used is affiliated with the factory. The seller's eBay name is "szhongjingtian". In an email, szhongjingtian signed her name as an employee of Shenzhen HONGJINGTIAN Electronics Co., Ltd.
FYI - this is how I access via RTSP:

If you use Windows OS you can utilize the software that comes with the camera.
NOTE: The PDF file at the link below is for a camera with the same camera PCB. All CGI commands from it that I have tried also work with this camera:
You can even turn the tl-wr703n into a camera using firmware packages found at the Madox.net blog.
I do not read Chinese but Google-translate provides enough info that it seems that a 50ms pulse of 3V at 200ma will operate the solenoid and a subsequent pulse will reverse the solenoid. No current is drawn in the quiescent state. I do not see polarity reversal mentioned so I assume that it is an identical subsequent pulse that reverses the solenoid's rotary current position(?). ADMIN - please take a look at the Chinese in the attached image and advise if a better explanation is disclosed there. Google translate cannot translate from an image. I suspect that it does require a polarity reversal because other, similar, IR-CUT solenoids that I have researched, such as one made by Sunnex (www.optics-online.com) state "Reverse anode/cathode to reverse mode".
In the FI8904W, the 50ms pulse is provided by an HC4538 multivibrator IC on a tiny daughterboard withn the lens area.
I'm thinking that it is, maybe, a MOSFET
ADDENDUM: I measured the connector as best that I could with my cheap plastic, manual micrometer, which is quite hard to do at the single millimeter level. After measuring and searching It is similar to MOLEX Part Number 501330-0200 but with enough dimension differences to not permit using the Molex part. The part is marked "NRL A3" I assume that it is a China sourced part but I cannot find a manufacturer that uses "NRL" as a logo. I have attached a drawing of the dimensions as accurate as possible with my cheap plastic, manual micrometer.
IF, however, my reading is a wee bit off, and the pitch is really 1.25mm, then the HARWIN M30-610-02-46 looks pretty good - EXCEPT for the pin shape. The HARWIN has a square .35mm pin while the NRL A3 has a rectangular pin .35mm X .2mm pin. Mouser sells the HARWIN M30-610-02-46 as a non-stocked item with a minimum quantity of 1,950 (rather exceeds my needs)
The FCI - 10114829-10102LF looks about as close as I can get with off-the-shelf parts. Newark stocks this part and will sell in quantity one at 16.7 cents each. Mouser stocks them at 17 cents each and Digi-Key sells them for 30 cents each.
Does ANYONE know who NRL is???
I contacted WansView's customer support and after much back and forth I got nowhere:
Partial Transcript of emails:
Me to WansView: The ALARM section of NC-541/W camera has a ALARM SERVER section
with fields for address, port, name and password. I find no documentation about
requirements for such a ALARM SERVER. It would appear to be referring to some sort
of ALARM SERVER software running on the attached network but documentation is needed
to utilize this function. Thank you.
Reply: Dear Sir, The alarm server is your own server if you have. If the user has his
own alarm server, he can use that server do help doing the alarm.
Me to WansView: I understand that much but what is the protocol for communicating
with the server?
Reply: there is no restriction with our items. You may use any one.
Me to WansView: Answer not useful. What computer software is used on the
remote computer server.
Reply: What kind of alarm server do you have?
Me to WansView: 我目前還沒有鬧鐘程序。我需要WansView兼容鬧鐘程序軟件的身份
I currently have no alarm server. I need the identity of WansView
compatible alarm server software.
Alternatively, please supply details of the alarm server interface to WansView.
Reply: We do not has any restriction for the alarm server. So every kind such as
telephone, HTTP server can both support.
Me to WansView: 描述一个例子
Pleas describe one example
Reply: (none was received)
I monitored my LAN with WireShark and saw that when I activated the Alarm Server
function in the camera, the camera sent an HTTP packet to port 56915 of the IP
address that I established for the Alarm Server in the camera. The text portion
of the message contained lots of alarm settings:
HTTP/1.1 200 OK
Server: Netwave IP Camera

Anybody know anything about the intended Alarm Server, its protocol, etc? Any ideas?
In testing with my WansView, turning a nearby light on and off produces an alarm. I haven't tested with the Foscam as this feature is not present in my FI8909. Has anyone tested this feature> Also, are there any other camera brands that have this feature?
I think that I am going to use WansView cameras (I like them the best) and the built-in Multi-View capability to display the four cameras. I'll be using motion sensing on a couple of them to send alerts via SMS to a cell phone as well as some audio indicator on a single PC.
I tested some software called Ispy http://www.ispyconnect.com/ and it looks promising but the totally free version is too limited. All of the features that I need require an $8/monthly web service in the middle. No thanks. If audio doesn't turn out to be a serious issue, I may put ZoneMinder onto a small Linux box and give that to her.
