  1. That was great Don. Thank you very much for doing that. Was that 720p or 1080p? What was the bit rate used? It does show that hands down, you need to be using solid copper RG59 with CVI. And even then like you mentioned earlier, it's still not completely sharp like IP MP. I've noticed the same thing in a number of other video samples too. It's an option to consider, but I'd only consider it if I knew there was good RG59 in place, period. The 1080p CVI recorders are NOT cheap either, more in line with NVR's, frankly. Even the 720p recorders are around 250 and then when add the cost of hard drives, you really have to carefully weigh how the money is being spent and what your needs really are. Thanks for the demo and write up. It needed to be shown how to at least get the best out of it.


  2. Have you checked to make sure you don't have condensation at night? Taking the dome off outside on a humid night can start a pattern of moisture infiltration that the camera can sometimes never fully correct from ever. That's just another reason why I really don't like domes outside, and I never get an ir dome either. Too finicky. You may have pulled the foam ring too far forward and ir is getting in at the back end. The foam may be just breaking down too. If you have a warranty, get a replacement. You can only do so much if it just won't behave. Also be sure nothing like walls or roof overhang is in the shot at very close distance. That can cause issues.


  3. How are you powering the cameras, separate power supplies for each, two four ways or one eight way power supply, or one power box where all are wired to? The multiple channel power supplies that are usually supplied with qsee packages aren't good enough. Either try using a power box or just buy separate 12v 1.5 amp or 12v 2 amp power adapters for each camera. At least try one separate 12v power adapter on a channel and see if it clears up. Could be a ground loop.


  4. Either that or just make a gmail account for only that purpose. But it sucks you can't disable email and still have it push to NAS. Alarm trigger is just that- an event triggered by a wired-in alarm system such as a window sensor or a wall module for a whole home security system. It's probably a software option regardless if your camera doesn't have alarm-in hookup.

     

    If you can't disable email snapshots while still getting them pushed to NAS, that's something to bring to someones attention to do something about it- whoever that might be at Hik. Maybe that could be solved with a next rev firmware.


  5. That is really great of you Don. If at all possible, I think it would be worth including some footage and stills using plug and play cable too, because that is where most people need to understand the difference, if any, between good RG59 and plug and play. There will be people who install the plug and play cable that comes with the kits, and there will be others that use the plug and play cable that they have previously installed. So any differences between RG59 and plug and play need to be demonstrated more than anything, to save what could be a wasted amount of work installing and/or relying on the more common and cheaper plug and play cable. If I had my hands on a system I'd do it but of course, I'm hdcvi-less! LOL! Thanks again.


  6. Yeah, that might be a win in that location. I was considering installing one in a similar way at my front door, and if it could give me cross street overview out front and driveway too, all the better. But I couldn't come up with an ideal spot for it. Really get your eyes out there and understand what the camera will actually see where you want to put it. If needed, get up on a ladder and make your head the camera and see what your eyes see. It's an investment, so you want to be sure that the multiple locations you think the fisheye can see actually sees them all. I was jazzed about getting one at one time but resisted because it wasn't the right thing to do. Good luck.


  7. Fisheyes are slick but I would think more about it for an exterior install. Multiple views and all is cool but not at the expense of resolution at critical areas that need ID capability. Just because you can split up the view and do e-ptz scans and see lots of areas from one camera, that does not necessarily make it the best choice and it is unlikely it will actually be better than multiple cameras. They are better used within boundaries which keeps all views at a resolution that won't fail you for ID. I'd consider them a good choice for one location and support for situational awareness of the other areas it can see - those other areas needing dedicated cameras of their own. No matter how capable a camera is, there are always limitations and sacrifices to relying on it covering large areas beyond the ideal of its ID resolution. In short, it's best not to rely on one camera seeing lots of area. Nothing beats dedicated cameras for each area.


  8. To the OP- are you using timers and if so, how is it going? Any cheap dial timer I ever used doesn't have a fast enough flip flop and that would be too long to have a camera down, imo. I also don't think dropping power to a camera every day would be good for it over the long haul. I prefer to keep working networked devices on line, rather than interrupting it just because. The only time I did a daily reboot was with my last router. It had a schedule for rebooting or 'healing' as they called it, right in the software. I came to understand it was more because it was a crappy router in the end. My new router doesn't have a schedule for that...and hasn't needed it either. Also weird of me, with all that is networked in the home these days, it has shifted my love of thunderstorms. I love a good [manageable] thunder storm but I've come to only be annoyed by them sending everything off line or worse, the potential to fry things. So now I prefer my weather nice and quiet so nothing gets interrupted.

     

    Managed POE switches give you all the options that you need.

    That's the way to go to avoid unnecessary rebooting all the time.


  9. Look at your recorded mainstream footage. If your settings satisfy your needs and the footage looks good, keep mainstream where you have it. Try it higher and see if you appreciate the difference. Typically you keep substream lower to make it easier to view your cameras via cell phone or internet remotely. This is especially true if you open all four at once. If the camera feeds aren't bogging down and freezing, you're OK. If you have problems, try D1 at 512 or even a little lower. It will not effect your higher resolution mainstream recordings. If you're recording substream as well that's fine, it'll be lower resolution recordings and can be useful if you want to check playback remotely as well. You'll always have the higher resolution mainstream files for the best quality. That's the benefit of two separate streams.


  10. Thanks for that Don. Much appreciated. I contemplated CVI but the 1080p units are rather expensive and the 720p units aren't as feature rich on the back end- including no support for alarm in/out. Having to swap out my cable was the deal breaker. I'll swap alright, but it'll be for networking cable and an IP system. Thanks again.
