Question: Does this antenna work with Foscam FI9821W?
Document: I installed this on a Foscam FI9821W camera located about 50 ft away from my router. There are three walls between the antenna and router. The 3dbi antenna that came with the unit wouldn't work at all but after installing the 9dbi antenna its working fine. I also installed this outside under the eve of the house. Its been outside for a couple of weeks now and no problems to date.
The antenna was ordered to extend the range of a FI8904W camera previously ordered but will not work for this camera. The online info did not differentiate between the needs of this camera from other Foscam cameras.
If you want to PROPERLY use your Foscam camera... you basically have to buy this in order to get it to truly work from even a short distance. After replacing my antenna with this one, all PTZ features worked perfectly.
I was having an issue with my foscam 8910 randomly loosing wireless connection. I installed this long antenna and it seemed to fix the problem. i was able to lay the antenna down on the surface the camera is resting on too.. the antenna is extremely long and looks weird when its standing up. laying it down it seemed to still work fine.. did i mention its LONG.. yeah.. it's LONG
I have two wireless Foscam cameras on my detached garage. With the standard antenna, the cameras would sporadically drop out due to a weak signal. I ordered one of these antennas with the hope that it would help strengthen the signal. In reality, the antenna didn't work at all on either camera. I lost what little signal I had to begin with. The quality of the antenna is very poor.
Connector only designed to work with Foscam Indoor models such as 18919w and NOT outdoor FI8904/5 models!!! Why is this being recommended for all Foscam IP cameras when I specifically searched for criteria to work on F18904w?? ?
I did buy it for an external camera as nothing pointed out this would not work for these type of camaras, however this antenna is not working for them.
I had to put the stock antenna back on the camera after messing with this DOA antenna. It literally does not work. A total waste of money. Do not purchase.
I purchased 2 9dbi antenna extenders and am happy with my purchase. They work as advertised and have extended my range on my cameras to about 135 ft from my router. I only had about 50 ft. before. I would recommend this product.
elbow is loose and sloppy. doesn't work. camera works better with no antenna than with it. DO NOT WASTE YOUR MONEY ON THIS PIECE OF JUNK!I thought at first it was just too far from my primary router. turns out its just a crappy antenna.
Answer: Yes, it will work with this Foscam
