Remote mount Antenna FI8910w

Postby zhavener » Wed Aug 22, 2012 3:20 pm

I am about to purchase a Cam to monitor the Interior of my barn and would like to know if I could extend the antenna to outside of my barn Via Coaxial Cable or similar to get better reception to the wireless network in my home.

Foscam sells a 9dbi antenna, which according to the specifications should be 3x more powerful than the standard Foscam antenna.

You could also take a look at an antenna cable, but keep in mind that the 2.4GHz frequency degrades a lot with the cable length (and it might be an expensive solution for a long high grade cable).

I don't have any experience with any of the above though.

Or you could install a wifi range extender/repeater.

I hope this helps.

You didn't say how far the barn is from the house. If you have a laptop, tablet or other network device you could carry it out to the barn and see what kind of signal you get. If the barn is wood there should be very little signal attenuation through the wall.

I have a wireless router setup as a wireless bridge at the far end of my house and it works great. Most newer routers can be configured into several configurations including repeaters and or bridges.

Good luck,
Bob

Foscam uses an SMA connection, but it's the reverse of the SMA connections on pretty much everything else, so a standard 7 or 9 dB antenna for a wifi router won't work without an adapter.

Here is a site that sells the adapters and extension cables, and they also explain the difference between standard and reverse polarity and male and female connectors:

Gender of SMA refers to the pins inside-not the threads: SMA male has threads on inside.

The longer the extension, the more signal strength you lose, so a 9dB on a 10 foot cable gives less signal than a 9dB connected directly to the cam.

If you have an outlet somewhere between the router and the cam you can add in a range extender. I got a good one from amped wireless. I used to have a hawking, it was weak and a major pain to keep up and connected.

Also, you could run ethernet cable from the cam to a range extender, and then it will connect wirelessly to the router. The cams are pretty weak on their wifi capabilities, range extenders are much stronger. This may be your best bet if you have the available outlet for the range extender.

You can get a little crazy with this and do many different things depending on how strong your signal is at the barn from the house.

You would first need to take a laptop out to the barn and see what signal strength you can receive from the Router/AP in the house ("If Any").

Please note that the lower the RSSI number, the better the signal strength is, when using this utility, for cases like this.

More here about how to go about that, using the free utility, shown above:

http://foscam.us/forum/fi8910w-randomly-missing-photos-in-email-alerts-t2846.html#p12899

If you can get a reasonable signal, you might even be able to use a 18dB Yagi antenna like this, for a 2.4Ghz wireless network. This could be connected to a range-extender or directly to the camera:

Here is an example of one such Yagi antenna being sold that has the proper SMA connector as well:

http://www.ebay.com/itm/YAGI-18DB-2-4G-WiFi-Booster-Antenna-For-Wireless-IP-Camera-or-Router-1M-Cable-/270830529983?pt=US_Directional_Network_Antennas&hash=item3f0ec1edbf

Note: I see no feedback for this Yagi antenna, and have no idea of how good, this particular one is. But Yagi antennas can work well for WiFi distance issues where you wish to focus the WiFi signal by direction vs. wasting power and sending it all over the place.

Of course you can find other Yagi antennas as well. You might even need one of these on both ends, depending on your situation. Which could be done by using another Router/AP if needed, connected to the primary Router/AP.

But as stated here. The first order of business would be to see what signal strength ("If any") you can get from the barn. Only then can any specific solutions, be suggested.

I realize this is an older message, but I am trying to do the same thing; Trying to get a camera to work in a metal building.
The antenna that is on it does work but only if the camera is not attached to the wood. Weird, I know.
So I bought the Yagi antenna because of this post and replaced the camera's antenna with the Yagi but the yagi gets less signal than the smallish antenna. I haven't attached the antenna to the outside of the building yet yet but surely if it was going to work it would work as well as the one I'm replacing? Right now the camera is sitting on an empty box and works.

I'm desperate for help. This is what I bought: 20dBi 18dBi Yagi WiFi Antenna RP-SMA Long Range High Gain Booster Directional 15F

Thanks,
Cheryl

Cheryl,

Does your outbuilding have power running to it? As long as it is on the same transformer as your house, check out powerline adapters. Better connection and stability.

Three things:

1. Not all Yagi antennas sold by all sellers are of the same quality. This is why I posted the link below. Because I also have been burned low quality Yagi antennas:

http://www.ebay.com/itm/YAGI-18DB-2-4G- ... 3f0ec1edbf

Note: The specific sale of the antenna above has now ended. However I trust the seller whom I would ask for guidance on where to get a Yagi antenna these days with the proper connector for the Foscam camera model you have. Because this seller sells many things which are compatible with Foscam cameras and most likely has contacts of trusted sellers these days for a good Yagi antenna that will work with your Foscam camera model:

http://stores.ebay.com/andy-camera-shop ... 3207259017

2. Yagi antennas are very directional and the farther you get from their wireless sources the more picky they are for being pointed in the best direction to get/receive the best signals.

3. Is the correct connector on the Yagi antenna. Sometimes the correct connector is not sold with the Yagi antenna and then the connection is very poor because of the bad fit on the cameras wireless connector?

Yagi aerial inside a metal building will be worse than an omnidirectional one for reception because the metal skin will cause the signal from outside not only to attenuate but to reflect around off various other surfaces and therefore come at the camera from many directions. Get the Yagi outside and aligned - and then things will get a lot better. However, as other posters have said, try power line routers first - a lot less hassle.
