bantham1 0 Posted November 7, 2009 Can anybody provide insight on Samsung Techwin products. This is supposed to be a new model. How good of a camera is the 4160? Share this post Link to post Share on other sites
serbokl 0 Posted November 8, 2009 I recently replaced a relatively inexpensive LTCMRH3508 camera with an SIR-4106. The problem is that the rest of my system is pretty crummy so a really good, responsive answer to your question is not possible, plus I am a newbie. At the same time I made the camera switch I also switched from siamesed RG-6 to cat5 and I still don't have any baluns to put on the cat5. I am also suffering, I am told, from relying on a cheap dvr running H.264. Even so, the 4160 does clearly outperform the 3508, especially during the day. The 3508 has no IR cut filter. About the only two things the two cameras have in common is that they both are very difficult to focus - way too touchy. A nervous person with shakey hands could NEVER focus either one of these cameras. I have very steady hands and find it difficult. Other than that, the build quality of the Samsung is excellent. It is supposedly pretty much state-of-the-art for an ordinary bullet camera. Its OSD menu allows a wide range of adjustment. I will likely get another one as I expand my system. No thread hijack intended here but I wish I knew if I can expect a video improvement when I put baluns on the current balunless cat5? Share this post Link to post Share on other sites
bantham1 0 Posted November 8, 2009 Thanks serbokl. Could you post a couple comparison pics so I can see the difference. I am thinking about upgrading my cameras to the 4160 and want to see an actual comparison. Share this post Link to post Share on other sites
serbokl 0 Posted November 9, 2009 I'll will be glad to post some comparison photos, assuming I am permitted to do that. But to be fair and accurate we need to do this after I install the cat5 baluns that I ordered today. In the meantime I'd sure like to know whether I should expect a 25-30 ft. cat5 run w/o baluns to show a significant picture improvement with them. Share this post Link to post Share on other sites
bantham1 0 Posted November 10, 2009 Here is a link to my pics. I have RG59 Siamese cable. http://s792.photobucket.com/albums/yy204/alschmid/ Here is a link describing what to expect with baluns: http://www.cctvforum.com/viewtopic.php?t=17848 Share this post Link to post Share on other sites

serbokl 0 Posted November 25, 2009 There was an unanticipated delay in getting and installing the CAT5 baluns for the SIR-4160 camera but they are now installed. I cannot see any difference whatsoever in the picture quality after the baluns were added. The original cat5 run between the QSD9004 dvr and the SIR-4160 camera was about 20-25 ft. When the baluns were installed it was shortened to about 15 ft. Below, I will try to make accessible screenshots I made of the original LTCMRH3508 camera (no IR cut filter, no baluns), the new Samsung SIR-4160 w/o baluns, and the 4160 with baluns. There is only the one camera on this system right now. I'm thinking the H.264 compression of the 9004 is limiting the potential picture quality ot the 4160 and I'd appreciate comments from experts regarding this, especially ones that would quantify possible improvement that might be expected by going to a higher quality mepeg4 dvr.

bantham1 0 Posted November 25, 2009 Were the screen shots made through an internet browser view window, or directly from the dvr? My pictures posted were made through an internet browser window and the quality is quite a bit better directly from the dvr, but I cannot seem to find an easy way to create a snapshot on the Avermedia 1304 other than through a browser window. Usually a browser internet connection window results in poorer quality compared to the actual recording on the dvr. I was expecting to see better results from the 4160's compared to my pictures from my inexpensive domes(for sale now in the classified section). Your DVR would be a suspect, as the 1304 is pretty high quality in recording (get one!). Share this post Link to post Share on other sites
serbokl 0 Posted November 26, 2009 All three of those screenshots were made with an Internet browser. Not that it matters but they were captured with FastStone Image Viewer which is one of the best image handling programs I have ever seen. Thanks for the tip on the AverMedia 1304. From my short looking around it seems those tend to be available mostly overseas and not so much in the USA. Where did you find yours? re video quality: I think it makes more sense to use less compression and more hdd. Share this post Link to post Share on other sites
bantham1 0 Posted November 26, 2009 I was lucky enough to find a used one cheap on an auction board. You can google it though and you will find some US resalers. Share this post Link to post Share on other sites
alanjh1965 0 Posted November 27, 2009 I have been asking about the 4160 and it's sister the 4260 Dome, they look good on paper. I did a post on a UK Forum and got a report back regarding the IR not been so good. http://thefireandsecurityinstaller.com/community/index.php?showtopic=31383 If any one has used the 4260 I would be grateful for a review Share this post Link to post Share on other sites
