The installing process should be fairly easy to do, even for the inexperienced. I will try to explain how to get this camera up and running. First connect the camera to your router, after that you need to use a configuration tool to change the default IP address with one that will work with your network.

To do this open up the included CD and open the folder named Tools then Config tools and inside there should be 2 files, one instruction manual and one .rar file. Unpack the .rar file and run the ConfigTool.exe file.

Press refresh and the software will find your camera and allow you to change the IP address. Remember that the default password and user-name is admin, you will need to change this later for security reasons to something memorable. You can also change PPOE from here.

When you have done the above steps you should now be able to access the camera by typing your IP address into your browser. Log in with Admin as both the user-name and password. Now you can change any settings you want for the camera.

Go to set-up menu and here you can do any changes you want. There are three different pre-set profiles Day, Night and Auto. By default everything is set at auto and brightness, contrast, saturation and sharpness are all set to a value of 50.

Play around with the settings here for both day and night to see which gives you the best image quality. Daytime works fine with all settings at default but for night time you may need to tweak it a little to find the best settings for your conditions.

For remote viewing with mobile devices use the included software called DMSS, available for Android, Apple, blackberry, Symbian and Windows operating systems. It also comes with a software called PSS (Pro Surveillance System) which we took a closer look at.

After youve installed it and opened it up you need to add your camera(s). Open up device manager, press the search device button and after its located your camera click add management.

This is how the alarm recordings shedule looks like.

Lets have a look at the image quality. This is a daytime image taken at late evening with all settings by default so it is a little dark, I should probably have changed the brightness a bit, but I think the quality of this camera speaks for it self with this snapshot.

And heres a nighttime snapshot. As I said in the beginning of this review, we have about 25m from camera to the road in this test. As you can see in this snapshot, 25m is about maximum length if you would like to see any details in your recordings.
