  1. This happens every day in my system. The cameras that point due east, then the southeast cams, then the south cams, shifting to the southwest, ending up in the west... Like they are following the path of something. Possibly an intense light source.

    Analogue camera has poor night time quality

    that is your problem. CMOS effectively stands for Can't Make Out Spit, and I erred in the spelling of that last word Sony Super HAD CCD or nothing.
  4. A router is a server with 2 network connectors, and software that determines when to connect them to each other. What is called a wireless router is a server with one network connection to a larger network - the WAN connector - and a switch which usually connects 4 ports to each other. a wireless router is a router, switch, and access point in one box. you need a switch to connect the cameras to each other and the computer you use to view the video. A router works fine as a switch.
  5. know this: if it is not up to code, your insurance company does not have to pay for a claim if the fireplace causes a fire, and the wiring is not up to code, the insurance company does not have to pay for damage caused by a completely different system with a completely different code. The appropriate section of the NEC is Section 800 https://www.mikeholt.com/instructor2/img/product/pdf/11LE-968-sample.pdf the NEC code book costs $220. The local public library has 2, the newer one is from 1985. they are purging books, keeping the ones that go out the most, and scrapping the ones that rarely go out. so, they are throwing out the vitally necessary NEC books and keeping Jacqueliine Suzanne and Danielle Steele novels. makes me wonder if the librarians understand the fundamental concept of a library. you might want to check the copy in your library while you still can.

    Port forwarding confusion

    first thing: google "what is my IP"? that shows my my IP is in Las Vegas. I am 600 miles away in New Mexico. in between, my IP provider is using NAT, which could take a chapter in a textbook to explain. I would have to use DDNS, dynamic DNS, which could take a chapter in a textbook to explain IF my service provider allows DDNS and port forwarding, I might need to update my DDNS info every time I take my cellphone somewhere. This makes the DDNS people crabby 5the best way is to store your video in the cloud, then access the cloud from remote locations. or pay for a fixed IP address, with a wheelbarrow full of cash.

    License Plate Camera help

    I can't see enough to prescribe a precise plan, but what I like to do is get clever: put up a big rural mailbox, put the camera in that, right out on the street. put a camera and DVR in a bird house or trash can, something that has a valid reason to be at the curb. it does not need to be a permanent structure, just an appropriate structure

    Rolling lines on camera

    you have a ground loop. you can read many tutorials on the subject and remain unclear on what that means. try an isolation transformer on that input. try that camera on a different DVR. try that camera direct into a monitor. try feeding that camera directly into a DC powered monitor with no connection to the system.
  10. Coming soon to a YouTube near you. I need to settle PC and pest control issues first.
  11. I have 20 cameras in my system at this point, 4 more coming. I put a bird house on the TV antenna mast and a bird house on a support pillar for the front porch, put cameras in these. The objective was to keep the cameras unobtrusive and dry The lenses block birds. They do not block hornets. Imagine a guest watching a hornet fly up to a fisheye 1.8 mm lens and entering the birdhouse, seen on a 32" TV. they leave permanent finger grooves in the Lazy Boy. If you put a camera in a bird house, spray the inside with a major coating of Raid, seal it up with RTV, foam rubber and a fender washer around the lens threads. It is much easier to do this before you install the camera than after you have hornets in your bird house and finger grooves in your recliner

    Drone Detection Systems

    jamming is illegal. period, the end the FCC is not funded by congress, for many years now. the FCC is funded by fines. they can fine you up to $10,000. I don't hate drones that much.

    Good quality CCTV Camera

    I'm prety sure he means low noise. as in, no snow in the picture.
  14. I assume you are asking me. 1 4 channel in the motorhome, wireless bridge to the house. watches the parking lot, back wall and back door 2 4 channels in a J box on the back of the house, as of 5 PM today. I switched to a different brand that wastes a lot of internal space, but the network interface works with Windows. just not enough room in the J box for 3 of these DVRs, RF modulator and a wireless bridge. these DVRs cover the sides, front and back of the house. 3 4 channel DVRs inside. one is 4 cameras looking out. one covers the hallways. the third covers the living room. wireless bridges because my landlord thinks my falling apart 1923 rented adobe is a priceless historical building, and does not permit drilling holes in what is really a decrepit mud hut. ergo IP over 802.11n, RF via the cable TV cable
  15. 1 16 CH DVR = all eggs, one basket. 1 16 ch DVR = 16 eensy beensy teeny weeny images on one monitor. not compatible with 62 year old eyes. OK if you have an excess 54" monitor you can tie up. 16 CH system = 16 identical cameras with 16 identical lenses. My system does not have 16 identical requirements. I want a tight image at eye level on the safe, and a wide angle up high on the back yard cam. can't get there with 16 identical cameras that will not take different lenses. I have 4 CH DVRs, connected to the network and tied into the cable TV system. RF modulators let me view 4 channels at a time. a wall of monitors lets me view all at once, without needing binoculars to see what I am looking at on a monitor 3 feet away.
  16. old, and old school, electronics tech here. my electronic systems tend to grow and expand, and I don't have to pay for skilled labor, so I tend to plan for growth IP cameras consume bandwidth. more cameras, more bandwidth. The DVR consumes bandwidth. how much do you have? 4 analog cameras to one DVR minimizes bandwidth consumption. If I was doing new construction ( in NM, where innovation in building is not a crime ) I would run PVC tubing for use as low voltage and fiber optic conduit. I would cut windows in the tubing at corners and reattach the cutout with a hinge. I would run Cat 5 or 6, fiber optic cable, RG59, 12 VDC and 5 VDC. I currently have a large junction box on my back wall that is big enough to hold 3 DVRS, 4 VDAs and an RF modulator. If I did it again I would get a bigger box that held 4 DVRs, because you always seem to need one more. I do not think in terms of camera locations. I think in terms of breakout boxes. many locations that were once camera locations are now multi camera locations; one each east, south and west.
  17. there is an easy way, and a hard way. the easy way has limitations, and the hard way requires study and skills. easy way: get two ASUS RT-66n router from eBay for ~$66. install DD-WRT on at least one and configure it as a client bridge. link your network to his network. you may need some directional antennas to make this work. you will be able to see his camera, he can see yours, at the house. you would need to do geek things to see it from a cellphone at work. hard way: DDNS: Dynamic DNS. you need to do this to have the capability to see your system from any internet connection greatly simplified: your ISP randomly changes your IP address using a system called NAT. NAT IPs are not routable over the internet. therefore, millions of people use 192.168.1.1 as their router IP. this makes it impossible to just connect to his network and vice versa, because neither of you has a very expensive static IP address, and you can't route the NAT address. you need to port forward your camera or DVR IP to the ISP. greatly simplified: your camera has an IP of 192.168.1.40 your router has a LAN address of 192.168.1.10 your router has a WAN address of 22.38.45.223 ( today ) you port forward 192.168.1.40 at the router if someone tries to open the routers configuration page at 22.38.45.223 they see 192.168.1.40; the cameras web page. they are not routed to 192.168.1.40, which can't be done over the net. they are routed to 22.38.45.223, which presents the interface of 192.168.1.40 where you would expect to find the interface of 22.38.45.223 chances are your ISP is using NAT between their internet routable IP and your system, so you need to get them to port forward through their NAT system to a static IP address. many ISPs will not do this. you need a third party DDNS service provider to finish the system. Your system updates the DDNS provider with the current chain of NAT addresses leading to a static IP address at your ISP, and assigns your system a port number. you are assigned an URL when you sign up for the DDNS system. when your neighbor connects to your URL, the DDNS system determines that he is trying to connect to your system, determines that today that means port XXXX at 22.38.45.223, which is routed through the current chain of NAT addresses leading to your port forwarded router interface, and he sees the camera interface at your camera IP of 192.168.1.40 chances are good that it will not work the first time, or the second, this is well into the geek zone.

    Legality of A-V recording in Texas?

    you need advice from a real Texas lawyer, not some random internet shmoe It is not unlawful ( it's legal ) for an individual who is a party to or has consent from a party of an in-person or electronic communication ( for a dude ) to record ( to record ) and or disclose ( and play back to other dudes ) the content of said communication ( what people say ) unless the person is doing so for the purpose of committing a tortious or criminal act. ( if you are not doing it to do a crime or something you could get sued for ) An individual may also disclose the content of any electronic communication that is readily accessible to the general public. ( you can record and play back stuff you heard on the scanner, CB, FRS, GMRS, ham radio ) it's legal to record and play back to other dudes what people say if you are not doing it to do a crime or something you could get sued for. you can record and play back stuff you heard on the scanner, CB, FRS, GMRS, ham radio in Texas

  21. your vertical streaks appear to be sync signals from another camera. you are seeing another camera, which has its own independent sync signals, and the beyond black sync signals show up black on this channel. in theory, isolation transformers cure this. in reality, where I live, not so much.

    Best indoor camera to catch them in the act

    Cameras: there are Super HAD CCD TV cameras, and junk: http://www.mintron.com/HTM/Q&A/Htm/Super%20HAD%20CCD%20camera.htm The lens is in front of the sensor. Jive junk cast acrylic lens = jive junk distorted image. a good lens is essential for a good image The lens harvests light. the size of the lens determines how much light the lens can harvest. do not expect Nikon quality from a pinhole lens camera The sensor is a limiting factor. a funky sensor behind a Nikon lens will give you a funky image. A 1/3" sensor is better than a 1/4" sensor because there is more surface area for the same image. Don't try to buy a camera and a separate lens to match. you can do a lot of spending for very little matching. if the term C mount is in the mix, it gets much worse. so, get a camera with a 1/3" Super HAD CCD sensor, with a big light bucket lens, from a retailer you can return it to if it does not work. there are four kinds of wireless video: self contained wireless IP: compete with other wireless devices for bandwidth, both your own and your neighbors IP over a wireless router: compete with other wireless devices for bandwidth, both your own and your neighbors, over a fast 802.n or 802.ac connection. analog: one or two cameras, susceptible to interference and interception, fussy FM over 900 MHz or 2.4 GHZ: 4 clean quiet channels. 2.4 GHz competes with other wireless devices for bandwidth, both your own and your neighbors. 900 MHz is probably not in use in most places. Analog and FM require a separate transmitter and antenna per camera, an omnidirectional antenna and one receiver, and a McGyver to set them up.

    CCTV wires

    I would think green would be housing ground, separate from power ground. I would test that theory with a voltmeter.
