Title: DCS-932L - Wireless vs. Wired
Post by: JavaLawyer on May 03, 2011, 12:35:59 PM

I'm looking to purchase the DCS-932L and would like to know from other owners whether the on-board wireless is adequate for streaming or gets bogged down.  If I make this purchase, the DCS-932L will connect wirelessly to a DIR-615 approximately 7 feet away with no significant obstructions.

Anyone?

Single Camera, no other 'users' doing heavy traffic? Probably good enough, but not comparable to wired...

If we assume a single camera and no other wireless traffic. . . will the FPS for wireless differ significantly from wired?

Thanks for your input.

At 640x480@20fps you would get about 4.5 Mbps on wired. On wireless, depending on interference, security-settings you should be able to get same throughput, but experience tells me you probably will get something like 3.5-4.0 (wireless-n, WPA2, 'noisy' area and some local non-camera wireless access).

I myself, at start-up of this process, was able to get 3 920's on wireless-g no better than 320x240 with acceptable footage or 640x480@5 fps (horrible quality if you need it as video-proof after the fact).

So, single camera, no other wireless whatsoever, free channel (use INSSIDER to find free/low usage channel), wireless-n, WPA2-PSK and no major obstructions between camera and router, you should get 640x480@roughly 15 fps.
WPA2 is quite a throughput-killer... But safety comes at a price.

Thank you.  Those numbers fall in the range I was anticipating (given encryption overhead, background interference, etc.), but needed to validate before consummating my purchase.  Given those metrics, there's no reason not to move forward.

Thanks again for your help.

UPDATE:  Just installed the DCS-932L and the wireless works flawlessly and throughput is not an issue.  Wireless works great for desktop viewing, mydlink, and the Android app (although D-Link throttles down the resolution and FPS for the latter two).
