    Extracting Video from Software

    Screen recorder then.
  3. You'll need NAS, Camera Licenses, and Cameras that the Synology Can support. Do read the supported list first. Basically you are purchasing IP Cameras with software. Almost all IP Cameras comes with Recording Software. You'll need to install the software on a PC to do recording, etc. So you'll need to consider the cost of 1 PC. Of course you can get their NVR, then it'll be like option 3. Basically NVR with Same Brand IP Camera. This is the setup I would recommend. NOT the brand though, there are tons of brands out there, you'll have to do your research. If you go with this or other brand is up to you.
  4. If you go Synology Way. $269.99 , come with 1 Camera License. http://www.amazon.com/Synology-Disk-Station-2-Bay-DS216/dp/B0185ZU0O2 Camera Licenses @ $64.99 http://www.amazon.com/Synology-Camera-License-Pack-CLP1/dp/B001MJ0JAO Total for 5 Cameras = $269.99 + 4 x $64.99 = $529.95 HIKVISION 8 Channels NVR - $270 http://www.amazon.com/HIKVISION-DS-7608NI-E2-8P-Network-Recorder/dp/B00VMNRZS4 Almost twice the cost of an NVR, and not including the POE Switches yet. And 5 Cameras license compare to 8 Cameras.
  5. SYNOLOGY is not a NVR. It's a NAS with NVR Addon Functionality. It comes with 1 or 2 free camera licenses, and additional licenses needs to be purchased. With those added in, it's normally a lot more expensive than purposed build NVR. Search for my another post, have some link for comparison to hardware+additional licenses cost for NAS and cost comparison to purposed built NVR. You might want to do more research on that. Most system record only on 1 bitrate and playback using that bitrate. There are some systems that does transcoding while viewing live, but not too sure if they do transcoding while doing playback. Some NAS and NVR also doesn't do transcoding while doing live view. They just handover the stream from the IP Camera directly to your viewing client. This means that dual stream feature depends on the IP cameras. Also if the IP Cameras (some cheaper one) supports only MJPEG, you'll be getting a MJPEG stream instead of h.264/5 stream. Due to the handover stream compatibility , I've also seen streams that can be displayed in monitor, and playback, but unable to view remotely live from the viewing client. Could be lesser now, but saw that before on some devices that mixed brands in implementation. Also, do you intend to use SYNOLOGY for it's NAS function ? Or just the NVR ? If you intend to use NAS, then just bear in mind that surveillance recording is a 24x7 job for the HDD. It'll degrade the performance of your NAS seeking/writing speed. As for VPN, thought it's a better idea to utilise the VPN on your router function rather than the VPN feature in the NAS as it sits behind your router, you'll need to open up ports in your router for the vpn connection, etc. But that's just my opinion. On the whole, unless you are going for just a simple 1 camera recording for your adhoc ip camera system and have already your synology in place, I would advice going for a purposed built NVR. Cheaper and more stable if you get the same brand of cameras as well. Less compatibility issues. Not forgetting that most branded NVR have a separate LAN with POE port built in. That'll keep your video streams which could be taking up quite a large bandwidth depending on your cameras resolution off your home network. For Synology (with dual lan), you'll need to configure that and also get a separate POE switch. Not all Synology NAS have dual lan port as well.

    Legal requirements for CCTV

    It really depends on which country/state. You might want to indicate that.
  8. Can't really recommend brand as I am located in Singapore. Product pricing are also different here and there for the same products. It really depends on what is available and the support level for each of the different brand in your own locality.
  9. What you may also wish to consider before recording at highest possible bitrate. 1. Space required. Higher bitrate means less recording period with the same HDD storage. 2. If you record each camera more than your upload bandwidth, you'll have problem viewing RECORDED footage through internet. Means if you think something happens 1 hour ago and you wish to playback the recording, you'll face difficulty to playback over the internet. You'll need to get back home to playback over LAN. Some entry level system, e.g. HIKVISION HD-TVI DVR also support line crossing/intrusion detection video analytic.
  10. If you never do any configuration on the router, it's basically using UPNP or the manufacturer's cloud services. From the problem you describe, the uPnp might not be stable. You might want to try manual port forwarding.
  11. I don't think you can get up to 20Mbps UPLOAD/Upstream speed from a ADSL. https://en.wikipedia.org/wiki/Asymmetric_digital_subscriber_line Max, as listed here, is only 3.3 - 3.5Mbps. For you to SEND(UPLOAD) video to the internet for you to View (DOWNLOAD) somewhere else, you should be looking at the upload bandwidth of your internet connection your CCTV System is connected to. Your ISP prob tell you the MAX DOWNLOAD speed for their line. For a more realistic bandwidth of your current connection, visit one of those many speed checking sites, e.g. http://www.speedtest.net and run a test from the connection you want to test. It'll tell you your current Download and UPLOAD bandwidth. Take not of the Upload bandwidth. Get a System that supports at least a Dual Stream. It'll enable you to stream through at a lower bitrate that's supported by your connection while recording at higher bitrate. As for event trigger, you may want to look at a system with more advance video analytic such as line crossing, intrusion detection rather than just Video motion triggered. All will generate alarms throughout the day, but line crossing and intrusion detection would generate less false alarm than pure Video Motion Detection. I normally don't advice push alerts based on pure video analytic as unless the environment is a controlled environment, you'll get fair amount of push alert on a daily basis. Most people switched that off after a short while as they get spammed by overwhelming alerts. Flapping curtain, car light shinning into the house, lighting, moving shadows cast by objects, swaying trees are things that might trigger the alarm. Yes, they are a lot more accurate now than last time, even a couple of false alarm everyday is a couple too much after a while and people start to ignore them. And don't get Alarm System and CCTV mixed up. They monitor different things and are meant for different functionality.
  12. It should be propriety cabling. But looking at it, most likely it's either Pin 1 - Gnd, P2 - P9 corresponding Audio + for 1 to 8. Or Pin 9 - Gnd, P1 - P8 corresponding to Audio + for 1 to 8. You can take a serial cable, strip of the other end, and try. Do get one that has all 9 wire. Some of them only have 3/4 in them. That's my guess. Anything goes wrong I'm not responsible.
  13. Could be your router configuration is wrong. You may have switch router to another one that uses a different subnet. If that's the case, you'll need to reconfigure your DVR. If you have a TV monitor, connect the monitor to it and see if there's any error msg. Sometimes it could be the DVR or the HDD that's faulty.

    Can a smart tv access dvr

    You can use a HDMI Extender. http://www.aten.com/products/Video-Products/Extenders/HDMI-over-Single-Cat-5-Extender~VE812.html#.VzA8jvlcRBc If your TV's using standard android OS, try installing iVMS-4500 from the appstore and let us know if you are able to configure it. Avigilon's a brand of Network CCTV Equipment. You'll need to change all your system to Avigilon, and recable to IP Network. Different from Analogue HD Cabling. ak357, tried Avigilon with Smart TV Browser ? Just curious to know.

    Extracting Video from Software

    Attach some screenshot of the software so someone here who had seen it before can advice you further. Some system comes with separate export software and player. Check the CD for other application. Otherwise worse come to worse, you can do a screen recording (which is not ideal as there'll be loss of quality).
  16. Update your apps to use the new changed external IP. If you don't know, check it in your Router, or visit http://www.whatismyip.com or http://checkip.dyndns.com from a computer connected to the same network to see your current external IP. If you had been on a static IP plan, your IP shouldn't change. Check with your ISP. If you are on a dynamic IP plan, it's only by pure luck and the practice of your ISP that results in your IP remains unchange for such a long period. Consider using a DDNS client (either on router or on your dvr) to keep track of your current external ip.
  17. Most likely it's a external connection cable that comes with your DVR that split the 9 pin port to 8 audio input (1 Gnd, others 1 to 8 Audio in respectively). Look inside the box for the cable.

    HIKVISION type of cameras supported

    DS-7204HQHI-SH support CVBS (NTSC/PAL) or HD-TVI signals. If you are using HD-CVI, HD-SDI, AHD Cameras, the system will not be able to display. Depending on firmware, you might also need to have "paired" cameras with same signal to make the system works. i.e. if you mix CVBS or HD-TVI signals together, they must exist in pairs/empty channels to make up for the pair. Newer hardware/firmware drops that requirement, but earlier versions required that.

    Can a smart tv access dvr

    Most DVR's web browser required a plugin installation. Unless they are streaming in pure HTML5 (even flash is being phased out), not likely they can work with your smart tv. Haven't seen any system that stream in pure html5 yet, some of them do javascript snapshot updates.

    Swann DVR4 motion detection

    Video Motion Detection are never that precised. Lighting changes, moving trees, etc will trigger the video motion detection. Check if your system support more advance analytic such as line crossing.
  21. You are using Mac. Most equipment manufacturer's support for macOS are lacking. Even for the big boys. Try looking for the accompanied software instead of using safari to view. That might be better.

    I know it's possible, but how and where?

    Been seeing a lot lesser PTZ tracking feature being advertised by companies these recent years. Most likely due to the emergence of lower cost multi megapixel cameras that can capture the required areas without having the ptz cameras moving about. Most of the time, the tracking looks damm impressive, but when put to daily practical use, they are mainly just a distraction and have a lot of blindspot if that is the only camera in the area. It's more to automatically zoom in to object of interest and captured a close up view, e.g. facial feature, licence plate, etc before moving on to the next object of interest so that when other cameras captured the incidents, there's always a close up view to trace back to to get a form of recognition. Nowadays, multi megapixel cameras can do that. There's only so much resolution you need to for recognition, doesn't need to count the facial hair or freckles on the face. If you got a budget for those systems, you can well afford to put in multi megapixel cameras system. Saw a camera that could scan and capture the facial images of everyone in one side of a football stadium around 5 years or more back (can't really remember) that goes for around $500k then. Can't remember what's the brand though. Then again, most of my projects doesn't involved actively tracking moving objects for recognition, so I might be out of the loop of those distributors.

    I know it's possible, but how and where?

    Using cameras might not be the most cost effective ways of tracking available parking space. But then again, it really depends on the structure of your parking area. e.g. Open space, enclose, multistorey, ceiling heights, etc. There's a well used parking guidance systems that uses proximity sensors to detect if a space is taken and display guidance to the empty lots. Google PARKING GUIDANCE SYSTEM. Proximity Senors are way cheaper than cameras and way more accurate in most situations. https://www.google.com.sg/search?q=PARKING+GUIDANCE+SYSTEM&tbm=isch However, in big open area, cameras might be more suitable due to the cabling and installation limitations. So it really depends on your area of deployment.
  24. I see, no wonder the local distributor gave us a free test set. Outdated model.

    Will someone please recommend a CCTV/DVR

    I won't rely on ONVIF unless there's absolutely no choices like you. Too much of a hit and miss. Even if it support, it support mostly basic function such as video streaming for recording.
