Last year I purchased an Axis 2100 network camera. I used it for a month or so, then sent it back for a refund because it was not an outdoor camera, though I was led to believe by some Websites that it could be put outside, and also because I wanted an auto-iris which is not an option on the 2100.

Last week I purchased the 4XEM W80 IP camera, along with a Spacecom Auto-Iris lens, and the TPH-5000 outdoor enclosure with heater and blower, from Provantage.com. Whoever the drop shipper for the 4XEM products that Provanatage sells, sent me only the enclosure support arm, and not the actual housing! I emailed Provantage because it was after hours, and told them of the mistake. I hinted that to keep me happy, they should send the correct product overnight so I could get it by the weekend. To my surprise I received a voicemail from one of the company reps saying that they would overnight ship the product to me to arrive on Saturday! Kudos to Provantage!

So now I have the 4XEM camera setup, and I took a snapshot with the identical settings of what I had my Axis 2100 set to. Unfortunately, the Axis image looks much better. I attribute that to the fact that the Axis camera has a progressive scan CCD, but the 4XEM camera doesn't. I paid a little more for the 4XEM camera, but it also has features that the Axis 2100 doesn't, such as MPEG4 video compression, audio, Auto-Iris capability, and the digital video recording software, that allows up to 16 cameras to be viewed, which Axis charges extra for.

Because of the MPEG4 video compression on the 4XEM W80 camera, the streaming video is much smoother than on the Axis camera. Also, the 4XEM W80 has a 1/3" CCD, but the Axis 2100 CCD is only 1/4". On the other hand, the Axis camera has true 640x480 resolution. The 4XEM camera appears only to have 320x240 maximum, and increasing the resolution (the setting in the config allows "Normal", Double", etc. - no actual resoltion numbers to choose from) simply makes the 320x240 image larger, which looks pixelated. So there are trade-offs, and basically, you get what you paid for.

I am not disappointed in purchasing the 4XEM product, because I paid less than if I had bought the Axis 211 which is is the equivalent of the 4XEM W80, and is nearly $300 more. I now have the 16 camera software, so I can add more cameras, and (I think) they can be AXIS cameras if I want better detail.

Conclusion: If you want high quality video, albeit with slower frame rates (though I believe some of the more expensive Axis cameras now have faster MPEG4 compression), buy an Axis camera. If you can skimp on video quality, and you want to save money, but also get more features in the process, buy a 4XEM camera.

Thank you for the comparison of Axis vs. 4XEM. I'm sure many people are going to find this interesting. Let me know if you ever do hookup the 4XEM 16 camera software to an Axis camera. I'm curious if that would work. Very Happy

Thanks again PapaWhiskey!

You cannot compare MPEG-4 picture quality to JPEG, JPEG will always have a better picture quality. But, it depends on what you're trying to achieve. MPEG-4 can have a audio channel, where JPEG usually does not. MPEG-4 streams at a lower bandwidth, but that only matters if you are trying to remotely view the camera or whether it is running on a network, and how many cameras are running. I find MPEG-4 the best cameras for remote managing or the sense of being there, where JPEG is better if your interest is security. Many times I have reviewed a crime scene using low resolution MPEG-4, and almost always it is difficult to identify the criminal in the picture because of the low resolution. But, I would say 70% of my installs are for remote management purposes, which MPEG-4 is fine. If you want to see license plate numbers, or recognizable faces, JPEG would be the better way to go.

Well I don't know what the rest of you think I have a camera set up of D-link DCS-6620G with the outdoor enclousur. I have no complaints so far the .05 lux low light mode is awsome its better than the human eye at least mine. the only thing that bothers me is the face that the camera has a 170 degree pan and they don't provide a corner mount for the outdoor enclousur so i guess 1 minor complaint. Has anyone else noticed that the 4XEM and the D-link Pan/Tilt/Zoom cameras area almost identical? even with the software? I know the D-link software wont let you use any other cameras besides there own. I haven't putzed around with a 4XEM yet but will soon.
