    Dahua NVR4832

    I have a question about Dahua firmware: General_NVR4xxx_GerEng_P_V3.201.0000.0.R.20151120.bin General_NVR4xxx_Eng_PN_V3.201.0000.1.R.20160409.bin The first one has a P in front of the version number, the second has a PN. Can someone tell me the difference? Can i use both in my NVR4832? Thank you in advance
  2. i had big troubles with Amovision Camras AM-Q1055R. After 2 cameras i bougth for testing where running for about 2 days one of them was giving up working at all. the other was loosing the picture and had stripes all over the screen. I had to reboot it and after 2 days more the same stripes appeared! These are cheap cameras and i think they are sold also under different names. so be carefull.

    is that all?

    Hi there, i have some questions about quality of the videos. I started half a year ago with survilance systems. First i bought a Samsung SDE-3001 system with two cameras each had 520TVL. I installed it on a table and tested it. The cameras had no zoom lens, so it was not ok for me. Then i bought an used eneo dlr1.2_04 DVR which can record up to 704 x 576 pixels, and set all possible settings to "very high". I bought 3 cameras VO-IRC56-2811TDN, 1/3" SONY CCD, 600L. DSP colorcamera, 600/700 TVL (color/bw), lens: 2.8-11mm. Below you can see the output The quality what i get is not what i expect. If you would have this on a TV you would throw that out of the window. Everything else works perfect. Before i invest more mony into this i thought i ask you experts. I think of switching to IP cameras with 2MP. Do you thing this is enought ore must i go to 5MP? But the bigger the resolution the harder the NVR has to work. In my environment most of the time only one or two cameras are working at the same time. Has anyone expirience whit NVRs which can deliver the same functionality as the eneo dlr1.2_04 for a reasonable price? Are there any suggestions you can give me?
