    Installation problem?

    Loose connectors? Insufficient amperage? Ground loop? Interference? If it's only happening at night, I imagine it likely has something to do with the IR or the extra power requirement. I don't know if I'd spend any time worrying about your cable, but bringing it indoors and testing it with a separate cable might be a place to start. That will at least tell you if it's environmental or a more direct problem with the hardware. Edit: I just saw you're using Cat6 cable. This is where I tell you that TVI, like CVI, is supposed to use solid copper RG59. That being said, someone is about to have a fit and tell me all about how Hikvision "says" you can use Cat6 cable. I've tried it. It didn't work consistently under any circumstances for me. That's all I'm saying.
  2. Any IP camera that comes with software to support recording and an access point to make it wireless. Dahua and Hikvision are always popular unless you want something more fancy.
  3. In that case, I would tell it's proprietary like many of them and you're going to have to find the right one based on the manufacturer of the DVR. It says MP4 but it's either some demented version of it or it's corrupt.
  4. The DVR looks like Dahua. It's all analog though, so everything you see that's also analog will likely be compatible.
  5. Not to be a smartass, and maybe I missed something, but if the file is in MP4 formart, is there a reason you haven't tried an an MP4 player? Most of what you tried is proprietary or not intended for MP4 to begin with.
  6. That doesn't look nasty enough for me to be a ground loop. The ground loop isolators may be helping to correct the issue, and I've seen that before when a ground loop wasn't at fault, but I think you have another problem. Like the toss said, try removing the UPS first. I think there's a halfway decent chance that that's your problem.
  7. I'd like to see pictures before making guesses. Ground loops look different from other power issues on the screen but are usually described the same way. "Someone posted at one point UPS' could cause ground loop problems by their psuedo sine wave." I don't know about the reasoning, but yah, some UPS units just don't play nicely with these systems. I wouldn't rule it out and it might be the easiest thing to check at this point.
  8. Try the link again. Their site isn't always working, but it is at this moment.

    Night cameras exposed by LEDS

    He gave you the answer you needed. The 940nm wavelength is where IR becomes invisible to the human eye. You are looking for a camera with the 940nm feature. They aren't common, because most people don't share your opinion. That being said, they are unjustifiably higher in price as they offer no benefit as the vast majority of the market sees it.
  10. This is my guess if they're IP cameras: http://www.dahuasecurity.com/products/nvr440844164432-676.html Posting pictures would help.
  11. Your time log shows a very obvious problem. Lines 72 and 64. Login from "user: default" directly from the GUI. In this case the GUI means whoever logged in was standing in front of the DVR and had the username and the password. After logging in, they made several modifications which then required that the DVR reboot in order to make those changes. Then they did it again. If you're telling us that you weren't home at this date and time, then someone else was standing at DVR making changes to it. Not outside messing with power cable, not aliens...just breaking and entering...and then tampering.
  12. +1 Don't start trying to fix a problem you haven't identified yet. You have your suspicions and they're probably right, but what if they aren't? I was going to suggest a trail camera personally. They aren't thought of as concealable, but there's a hundred ways to them, especially around a home.

    Recommend the NVR, etc. for our project?

    The NVR will likely only give you the video files separately. This means you'll have to view them separately one at a time. The microphone will be paired with one of the cameras on the NVR so that audio will play with whatever cameras feed you have it slaved to. A little video editing software and some effort will let you compile/convert those videos and audio any which way you want. As it stand though, the NVR will likely not give you what you're after on its own.

    They exist. It's all about wavelength. It has a relatively short letter/number identifier but I forgot what it is. I'm sure someone here knows. You need to know that "invisible" IR is also weaker IR in many cases, meaning it won't reach as great a distance as the alternative and may also be dimmer.

    disable TPZ on Bosch 600 series

    The settings are going to be on the DVR. Any manual you find for the DVR is going to be a nightmare; don't waste your time. Try searching for articles or videos about what you need by the make and model number of the DVR.
