Avoid these cameras if you can, May 28 2012
Please avoid these cameras if you can.
I installed these cameras and wondered why I was having issues with the wireless wifi in my home. I'm a network professional, so I am well equipped to troubleshoot these cameras.
I was given the run-around by Lorex support staff for quite a while. But I tested several layer 3 switches as I have several high-end units in my home. And I used wireless analyzers to determine interference volume.
When these cameras are connected in your home, they blast out data on channels 1 to 13 on wifi 2.4 ghz. As a result, any device using Wireless A/B/G in your home will not work or will experience packet loss known as jitter causing resending of data. Packet test showed losses of 5-45% versus 0% previously depending on the time of day with these units disabled. Upload speeds were dropped from 2500 kb to 10 kb. Download speed tests dropped from approx 25000 kb to 500 kb. This was tested in a small 500 sqf area with the cameras 15 feet away from their receiver. With wall and ceiling mounted wifi routers.
Lorex support staff was very clear there is no way to resolve the wifi issues on these cameras, that they cannot be locked to a channel, and would not provide any additional support. Advice from Lorex overseas support was to remove all the cameras or all the wifi routers from my home. Lorex has yet to reply to my emails or calls and provide a method for me to obtain a refund, and it is no longer within 30 days for the vendor.
To be clear, the vendor I used on here was fantastic and did everything they can. But these cameras are walking wifi bombs and need to be avoided at all costs. They cannot be used in a residential home with wifi unless you have all wireless-N 5.0 ghz compliant devices (i.e. no cell phones, no tablets, no netbooks). I'm now out about $600 for "interference free" cameras provided by Lorex and I recommend against these.
