  1. Hmm... let me explore that. That's the test set we have for Dahua. Both Dahua's DVR and Dahua's CVI cameras. Can't find any control for IR control. But as long as you can't switch off the IR, it'll switch to IR and go b/w. Think it have a mechanical IR filter, need to double check for that.
  2. Do you mean their Dahua IP Cameras system or their HD-CVI DVR w/HD-CVI Cameras ? I can't seems to find the settings you referred to that allow for scheduled switching of the IR light for Day/Night settings in Dahua HD-CVI DVR with CVI cameras. If it is just the scheduled color setting on the DVR side for camera color adjustment, then quite a number of DVR do support this function. See attached screenshot for Dahua and HIKVISION DVR. Unless the DVR is controlling the settings at the camera, it'll be almost like doing "enhancement" from the source, rather than "enhancement" at the source. Like photoshop the image after the shot had been taken instead of adjusting the camera to take better shot. Not too sure if the Dahua's Setting's adjusting the cameras' inbuilt setting or just adding enhancement. Forgot to try if the setting works with normal non-cvi cameras. Will try to test it out next week when i get back to office. When at night, the IR light is on for the Analogue HD Cameras, the IR light will wash away most of/all the color unless you are able to control the IR light on/off through a schedule available on some IP Cameras. Setting the scheduled color settings are not going to bring the color back when the camera switch to IR mode during low lighting. See attached screenshot for HIKVISION IP Camera's Scheduled IR Light settings. However, fixing the schedule means that if during a dark overcast/rainy day or early sunset/late sunrise, you may end up with less than optimum lighting. We normally use the scheduled IR Light setting/disabled the IR light for timelapse photos with slow shutter speed at night. Another project that we disable it is when we require color rendition of the images and white LED light are installed to illuminate the area of interest and IR lights are disable to prevent the camera from switching to IR mode. Most of the better cameras will switch between IR/Normal and auto adjust the color/brightness during daytime and night time. WDR functions are also available on some that allows better lighting rendering for both bright and dark areas in the cameras view. TS might want to invest in a better camera (some comes with OSD for more fine tuning) instead of tweaking the DVR's scheduled color adjustment unless the cameras are installed in location where schedules are fixed. e.g. indoor where lights are on/off at certain schedule. Otherwise when the cameras compensate, you might end up with a too dark or too bright images. But that's my opinion based on equipment/situations I encountered. Maybe there are situations and equipment where this settings makes a lot of differences.
  3. You'll need to explore cameras that allow you to schedule the switching schedule between color/blackwhite. Not so much of the DVR. Some IP Cameras allow you to do that, e.g. HIKVISION IP Cameras with IR. For analogue, mostly can't unless you going for higher end range of cameras which doesn't make sense as the price range would be more ex than the IP Cameras that can do this. However, doing schedule switching means that the cameras will NOT switch to b/w mode to compensate for lower lighting during overcast or dark raining day.

    CCTV system viable through phone

    It's not recommended that you set alerts based on Video Motion Detection,. Video Motion Detection is NEVER precise. No matter how you set it, you'll get false alerts. It's just a matter of more or less. Video analytics such as line crossing, intrusion detection are more accurate. But false alarm still exist, just a lot lesser.

    ONVIF camera with RG59 wire

    Took a quick look on the specs. Most likely it's a Analogue HD Hybrid DVR. Cameras input are either AHD/CVI/SDI/TVI (doesn't specified) through BNC and also support ONVIF IP Cameras. It's not ONVIF over BNC. The cameras catalog are all HD-TVI. http://www.nuvico.com/index.php?route=product/category&path=138 You can find ONVIF pinhole/spy cameras, and also TVI pinhole/spy cameras.
  6. Get a IP Camera with SD Storage. The Camera must be able to configure to take snapshot at interval and store them in the SD storage. NOT all cameras support that. Some only allow for video recording, or snapshot when event is triggered, e.g. motion and NOT at an interval. We used some models of HIKVISION cameras, and they do support it. For solar, you'll need a panel, charger, battery. Specs you'll have to calculate the consumption of your equipment. Amount of sunlight also matters. Networking, a 3/4G Router with a 3/4G Plan. Did quite a number of such projects, and they are still running. Some project completed and time lapsed video produced.
  7. Just bear in mind that Video Motion detection is never that precise. You'll constantly get alerts. If it's looking at outdoor with trees, etc, it'll be worse. To be more precise, you'll be looking at video analytics, line crossing, loitering, etc. Even those have it's fair share of false alarm. Unless you are working as a security guard and basically look at the feed 24x7, you'll need some form of recording. Otherwise, there's a intruder running pass the alert trigger area, you turn around 2 secs later, you'll miss that.

    Please help me decide...

    Video Motion triggered are never that precised. You might always miss some recordings that are crucial no matter how you tweak the settings. Nowadays I normally advise continuous recording at lower quality and higher quality recording when triggered. This reduced the numbers of calls from customers asking how come there's "missing" recording. Storage is relatively inexpensive nowadays. Just go for more storage.
  9. Check on the Mac address of all the cameras/nvr and your new PTZ ? There are cases reported where 2 devices had been flashed with the same Mac address, especially those aliexpress sets.

    The problem DVR does not start!

    I can't be sure about it. But that's one way you can troubleshoot.
  11. You can backup the configuration as well. So just in case you mess it up, just reload the configuration file.
  12. Most likely it's the HDD faulty. You mentioned it'd been runnning a few years. Is the new HDD you try it with a SATA 2/3 HDD ? Some older system doesn't support the newer SATA 3 HDD. Try it with an older SATA 1/2 HDD.

    Please help me decide...

    You actually already list out what you want. 1080P ( 2 or 3 Megapixel) IP Cameras that support POE. 2 of them outdoor PTZ. 8 or 16 Channels NVR with min 8 POE. Just bear in mind, if you are looking at recording at 1080P live for 8 cameras, you'll need around 6TB of storage for every week of recording. So if you want around 1 month of recording, you'll need to put in around 24TB of harddisk. Largest HDD size is 8TB, so you'll need ard 3 HDD slot in your system. And NOT all system support 8TB (just launched not long), mostly only support up to 4 (according to their manual), so you might need something with 6 slots for storage. You mean taped on your neighbour's internet connection ? I rather assumed you mean without EXTRA fees on top of what you are paying for internet connection now. Most don't need. Just need to configure the NVR and your Router for external access. Also ensure that your ISP doesn't do any port blocking/traffic filtering/shaping/proxy on your current internet connection.
  14. HIKVISION produce their camera for local market and international market differerently, mainly with different firmware (not too sure if it's only limited to firmware or other internal hardware as well). There's quite a number of online China vendor that took the sets meant for local(china) market and flash/hacked them with international firmware. They are a lot cheaper than getting from authorised source, but HIKVISION and your local authorised reseller/distributor will not support them. You'll have to figure out how to get it working properly/troubleshoot it yourself if you have any issues. And it's not advisable to upgrade their firmware as doing so vie the normal way would possibly brick them.
  15. Brochure/Specs never QC properly ?
  16. Check firmware here. http://overseas.hikvision.com/en/download_89.html Be careful if you are using Aliexpress/Ebay sets as they are mostly Local set hacked with international firmwares. Alternatively, backup the configuration and reset everything (NVR and Camera) back to factory default and try again.
  17. Get a cheap IP camera rather than tinkering with raspi/webcam if you want something working rather than as a hobby trying to get something to work. I assumed your time is more valuable in this case. Cheap IP cameras are , well, cheap.

    is there ahd rf modulator

    If your TV only have RF in and no AV in , it's prob time to get a new one. If you are using AHD system, you prob want to get a monitor with HDMI in to enjoy the resolution.

    The problem DVR does not start!

    That could be the problem. It may need a hard drive installed in order to work.
  20. Think you got to change the camera to DHCP and then connect to your NVR in order for your NVR to configure it. Most likely you got a PTZ with a older firmware or had some prior settings in it. Did you try doing a factory default setting on the PTZ before connecting to the NVR ?

    Vga out is not working?

    Did you check with the vendor ? Can't find any information online and I'm not going to open those .doc files that the search results returned. This is one of those unbranded equipment. You'll most likely need to check with the vendor. Either 1. The port is there for show and not a working port. Seen a few of those before. Including on PC as well. 2. There's a hardware/software switch to alternative between HDMI/VGA (Only 1 can be working at any one time). - Try disconnecting your HDMI and only connect a VGA cable. Switch off the system and power it back on and see if there's output on VGA. 3. Some configuration in the DVR to enable or select the port. Here's a russian site on it. https://www.drive2.ru/l/8412045/ Can use google translate to english.
  22. I assumed he's on budget. These are not budget equipments. " title="Applause" />

    HD IP IR speed dome help

    In that case, let's assumed the manual is right. The camera is set to 192.168.1.110. You are on wrong different and thus can't connect to the camera. Try this. 1. Manually configure your Laptop/PC's IP to 192.168.1.100 (Gateway 192.168.1.1, Subnetmask 255.255.255.0) Google "Set Static IP on Window" if you have problem doing so. 2. Type http://192.168.1.110 in your browser. You should be able to connect to your camera. Change it to the same subnet as your router. 192.168.254.XX Change your PC/Laptop IP setting back to whatever it was. Alternatively, check if the vendor provide you with a discovery program to do this without meddling with your PC/Laptop's IP.

    Cheaper Costco Systems and Remote Playback

    Visit http://www.speedtest.net/ from your store's internet connection. Do a Test. There'll be an Download Speed and Upload speed. You are using 3MP cameras. You'll require around 10Mbps per camera, ard 164Mbps for 16 Cameras @ 30fps medium quality compression. http://www.supercircuits.com/resources/tools/network-ip-security-camera-system-bandwidth-calculator Your upload speed should be at least 164Mbps for your internet connection to be able to stream 16 cameras smoothly. If you have anything less than that, you'll not be able to stream the cameras out smoothly. Do a speedtest on your iphone as well. The Download Speed you get should also match the bandwidth required as above for smooth streaming. If your NVR support dual stream, you can configure the substream at a lower bitrate. This will enable you to stream the video smoothly if your bandwidth doesn't meet the requirement above. However when you playback on your iphone, the system will still required the main stream bandwidth to playback. Otherwise, check with your ISP for a faster plan. These kinda speed is only achievable vie fibre broadband. We have these kinda speed here in Singapore (Mine's 240Mbps/227Mbps now). There's also 1Gbps plans. I'm not familiar with internet plans on your side.
