  1. The function you're talking about is sequencing. Some DVRs allow you to have it so only live cameras are included in the sequence, others just go through all inputs

    help please

    You're really gonna have to give more specifics such as make/model as well as pics

    2 new additional cameras faulty

    I agree. Sounds like you're going the best route and with a backup plan should you need it. Hope all works out well
  4. I'm honestly not sure about 1200tvl but I'm suspecting its a bit more of marketing. Alot of people were putting 600tvl and 700tvl cameras on D1 DVRs but D1 wasn't really fully using the cameras potential but then 960h came along and it's supposed to use 700tvls full potential. And that's where I understood 960h to be capped. But now I see a lot of talk of 800tvl cameras on 960h. Again, I'm not positive as I've only seen mentions of 1200tvl but I'm thinking it may be hd-sdi which uses a different dvr than 960h. There are however some hybrid DVRs that you can research.
  5. Before planning on using one manufactures nvr with another manufacturers cameras, check comparability as they don't all play well together.

    You can use BNC to RCA adaptors like these. They're very inexpensive. http://www.sweetwater.com/store/detail/NBR271?utm_source=Google&utm_medium=PPC&utm_campaign=none&device=m&network=g&matchtype=&gclid=CIDF7YO3scACFQwV7AodnTgAYA
  7. If you really want to make use of the 700tvl cameras, go with a 960h dvr.
  8. Wow, chill out man. You're the one asking if you should use 30fps. I know very well that how they're powered has no effect on those settings. I asked it just as a friendly question because I was curious of how your project was being set up. You asked vague questions and people hear we're trying to help. Sometimes it takes questions to answer questions. But you have been vague and rude to those questions. Did you just put up this post so we can be amazed by your wonderful skills.
  9. How will they be powered, from individual houses? I agree that 15fps should be plenty. Also using h.264 will reduce file size.
  10. When you see 700 or 800tvl mentioned, that's analog typically (though there are some ip cams that are lower res like that) Sounds like you wanna stay with ip. 2MP and 3MP. When trying to get license plates, you need to study up to make sure you do it right. There are a few good posts around here that go into great detail as far as proper setting of field of view and exposure, etc. One thing I'll say is that you shouldn't expect to get one great overall area shot and still see plates in great detail. It's about really knowing the choke points and keeping a tight aim to see the plate. Also most nvrs that I know of will email motion events as they happen but keep in mind that the motion settings on most cameras are far from perfect and many little events such as bugs will trigger motion as well as dust that wouldn't even normally be visible to the eye. One alternative is to use alarm system pir motions (dual or tri tech are best) and the them to available alarm inputs either at camera or nvr depending on setup. I also would say that because its a business, I personally would try to rely more on visible light than ir light for night time. To me LED flood lights really light up well for recording. There are many ir cameras that don't do a great job of lighting. The quality really differs from camera to camera. You can also buy separate ir illuminators made by companies like Raytec. They work great but are not cheap.

    Surveillance camera questions

    Glad to hear you've got a plan on going forward. I hope it works out for you. Just beware that you may have to run new cables (which the set may include some premade ones) if the original cables are coax. If you own the 700tvl cameras (not sure if ADT leases them) then they're worth holding onto as 700tvl aren't bad as far as analog goes but it was probably the dvr that was more of a bottle neck (4cif or D1 resolution which doesn't use all if the 700 lines) Good luck
  12. Yeah, sorry. Some DVRs have alarm inputs that can be used to trigger recording but your dvr doesn't appear to have them.

    IR Reflection

    It shouldn't be an inherent problem with all domes. All the domes with ir that I have used, have a boot around the lens that pushes up against the inside of the dome so that it separates it from the ir to eliminate the reflection. A good example of this is also seen on the ball cameras where the lens is separated from the ir.
  14. Not sure if your system has alarm input ports but one option is to wire in pir motion sensors to enable recording rather than relying on the camera motion detection. Sorry if I missed it in your post but is this actually a dvr with analog cameras or an nvr with ip cameras?
  15. Could the problem possibly be coming from digital noice reduction (dnr) or wdr being set high? Also I understand that hdsdi is very picky on csble quality, just wondering if all cabke on this intall is equal and if problem is on all the cameras or just one.
  16. Can you keep that camera hooked up inside for a matter of days or so to make sure it keeps ok? I'm wondering if the other camera you put in its place will start to act up. What model cameras are they? Just in case it helps, like if someone has had a similar issue with a particular camera (or the chip used)
  17. Sounds like a cabling issue. I would suspect the BNC connections. Also is it possible that cable is run along high voltage or something? Sorry, I just re read and saw that you put another cam in and it's working ok. That's weird. I've seen issues with the iris where it's whited out all day and then has picture at night but did you say your camera was acting up at night too?
  18. Another place to look for more information are the websites for the manufacturers and suppliers. Also youtube can be a good source for some installation how tos.
  19. IqInvision has pretty good low light capabilities. They call it light grabber. Personally I think viewing through glass, with it without ir can give problems depending on light in the room
  20. Not sure which of you "knows" more but wrong information is wrong information and should be corrected for the benefit of those who may otherwise not know. Look up the meaning of IDC

    Disabeling or covering IR LEDs

    It just took a higher level of expertise to bring it up
  22. Be careful when choosing cameras and an nvr. Not all manufacturers products work well together. Have you looked into hikvision or Dahua. I think you'll find a larger selection there with better quality. You can save money with something like HD-cvi if needed. I understand, you wanna save and not spend a million bucks but its really about getting the most bang for your buck. Getting cheap cameras and then finding they don't work with your chosen nvr or they fail, you save nothing.

    Disabeling or covering IR LEDs

    What camera are you looking at. I'm assuming its analog? There are many interior cameras without ir and they would be cheaper usually. Plus keep in mind on a dark stage, the camera will be in night mode (black & white). On ip cams you can disable this. If an analog camera has an osd feature, you may also be able to override it.
  24. You are correct, cca is copper coated aluminum.
