Hello Tomislav, I havent used the software - only read about the product from a past issue of Security magazine http://www.securitymagazine.com/ seems the UTAH SD (Sheriff’s Office) has has success with the product as well a design consult I know involved with the TA back east told me about the program. At this point I deal mostly with consult for wire management/infrastructure - electrical design pertaining to custom entry and building facilities - freelance design oversite related to the construction industry. Perhaps others here on the forum can help you attain better quality with your exsisting hardware. I can tell you that often quality issues can be overcome or improved even with lower quality devices by revisiting the actual layout and build - smart distribution systems and wire management with special attention applied with all communication connectivity interfaces. Regards

Yes Soundy, this is the one, I have to say I am a bit disappointed because to take the 1 -2 h footage from the DVR (front USB) it takes 5-6 hours...that is really bad and most of the time it gets stuck so I have to repeat. It is better to take 30 minutes few times.
Wolf thanks a lot for info, in my current company I had to find contractors who did an installation of CCTV system. Problem was that we had few installations so we were all the time adding additional cameras and sometimes I was not there to supervise so I have a bit mess. We also have (addition to DVR) a PC based system with 16 channels (2 cards) as well, and I noticed that each company had different clue of how to put in the connectors and pull the wires (near the electrical cables which degrades the quality as well).
Do you guys have any good company to have CCTV trainings or even online videos. I am kind of new but still have some experience, basic at least.

Hello Tomislav, its always good to think future with smart design, thus allowing for simplified access later to support updated technology or expansion. Dependent on the actual detail/spec of the walls floors and ceiling type at your locations there are many distribution and wire management systems that can be researched for your applications. New construction or retro-fit, careful attention should be detailed regarding wire management - as well codes, building requirements etc. In general maintaining the bending requirements of cabling and cable paths ensure noise reduction integrity and overall performance. Devices will only perform to rated spec with proper install methods. Even the application of "high quality" products are dependent on the actual mechanical building of a system. Ive found that most quality issues arise from poor design. Older facilites often need to be revisited due to systems that are trapped by conventional behind the wall wiring or sloppy add-ons that are very difficult to gain access to correct - trace or have been stepped on by other trades. Your reference to connectors is a prime example of the weakest link....poorly constructed terminations often lead to call backs and failure to observe Power Quality issues ( device power specs often not followed or tested, circuits etc) From the DIY and even some "professional installs there often is a "plug and Play" attitude that can be problematic whereas the time is not taken to measure and scope out all the details that are key to attain a quality result. My comments are not only directed to this specialized field (CCTV-related) but general construction/build in general. Its a good idea to always have your contractor submit you with a design-plan with not only cost/material but actual layout that you can approve or have examined by a qualified source before you accept and proceed. Good Luck Regards

Do your cameras by themselves look good if hooked up directly to a TV? If not then there's not much you can do as that's your source image. You may be able to get better night time performance by removing the infrared filter under the lens, though.
Otherwise if they do look good, you may want upgrade your image capture device. As I was suggesting another folk on this forum, the Avigilon networked video encoder is thus far the best I've found. It's a little box that turns 4 analog cameras into IP cameras which you can access on a PC. This allows you to transmit images over longer distances in digital format to avoid signal loss, too. From my experience it makes all analog cameras look very sharp on monitors. You will need a PC and a single-camera software license though, but with the encoder it's still cheaper than a standalone DVR. Hope that helps getting the most out of it!
