    I recommend you to use Hikvision or Dahua POE cameras, most of them under your budgets, you can select some bullet and turret type for installing.

     

    But besides cameras, you require a NVR or PC for storage, I recommend you to buy a NVR too for 7/24 recording.

    I agree. I have Dahua and Hikvision cameras and they are fine. It is not easy to set up the correct motion detection but once you done it it is OK

    hi

    depending on how much money you plan for this, I suggest a synology system and some Dahua or Hikvision cameras. However each camera license costs 50 USD (1 camera license is free with the synology).

    The NAS also has to be connected to an UPS and in a well secured place.

    And you need a reliable switch, which has PoE option. Cisco has some good type, but they are not cheap.

    One thing to note with the Synology NAS units like the 1511+ i have they have dual NIC's in them. I use them to isolate the camera traffic on its own subnet and the other NIC for access to the unit.

     

    i plan a separate switch as well, but the essence of a switch is that the traffic is only between the nodes, so the caemra traffic does not interfere with other traffics. In case of old HUBs yes, but switch, no.

    hi thanks for the info.

     

    well, to work directly to NAS is an advantage, but this kind of motion detection is just unacceptable.

     

    as far as I understand if a motion is detected , the camera records only 1 sec and then skips another sec? or it records continuously when motion is detected then if not, it stops and starts again but at least after only 1 sec of non-recording?

     

    I am thinking of Arecont cameras just because of this but as far as I know they cannot record directly to NAS...so I need a 'server' installed where the NAS is mounted.

    Hello.anyone has experience on Arecont IP cameras?

     

    I planned to buy vivotek but it cannot record long time as far as I read here.

     

    Now I am thinking Arecont 2155DN and 1355

     

    Can these types record directly to a NAS/NVR? and can they record minutes, depending on space available and setting?

     

    thanks

    Hi

    Suppose I have a vivotek FD8161 or higher end type vivotek camera and a Synology DS413 NAD/NVR

     

    The camera is set to motion detection when 1280x800/10 or12fps recording is set. Is there a limit of recording time other than the free space on the NAS? Suppose somebody is in 'motion' in the area of the camera for 10 minutes. will the camera record all 10 minutes in 1280x800/10fps if the NAS have the free space?

    can the camera set to record directly to the NAS without a server/management software continously running?

    if not, what type of camera u suggest for this purpose which works this way?

    Thanks

    no. this means you run a client app on your smartphone that connects via internet to the nas. see the picture i posted above.

     

    the NAS would not be connected to the internet. that is the problem. it would be on a separate network, and even if it were connected to our LAn the LAN is protected by a PIX from the internet so external requests are not allowed. the only way now I see is to connect to our LAN via VPN and using a remote viewer to connect to a local PC which has 2 ethernet cards one is connected to the subnet and there to mount the NAS and to see it's content.

     

    what I want is to "call" the NAS (ring it) and when it received a call it sends a picture to the number it was rung from. is this possible?

    if you want to simplify, get a nas that has nvr capabilities itself, rather a separate dedicated pc.

    wow, thanks. it seems good, but how does it work? it's just a storage unit or more? to set the cameras to where and when to record i still need a PC and the management software. or it can be set on the cameras via the web interfcace and then i do not need a server? how can i see the live feed then? only camera by camera? if i want to see the feed of 3-4 cameras simultaneously i still need a server with management software, aren't i? many thanks

    hello. many thanks for the info.

     

    however some things are not clear.

     

    1. what is the problem with dlink switch? we have them and no problem. earlier we had linksys swittch and it was a disaster, it turned out that the capacitors inside were liquid not solid based. cheap chinese generic capacitors. I heard that cisco has low quality of switches, linksys was also bought by cisco.

     

    2. if we buy an sg300-10p unit as you suggested and we have 8 cameras and want 1-2 more, we are out of options.

     

    3. we do not have problem to power the cameras separately, altough the solution you mentioned is better. but i do not want cisco swicth.

     

    4. you misunderstood. we do not want motion detection emails. what we want is to see the picture of the camera from outside whenever we need to. so the camera (or server or nvr) only sends it if an OUTSIDE request is initiated by the user. is this possible? (without a PC only if i have a mobile phone with MMS capabilities).

     

    5. what's your problem with vivotek and dlink cameras? what type do you suggest then? (minimum 1.3 mpixel)

     

     

     

    first, ditch the d-link switch for your cameras. i've used similar models on a couple sites now and had no end of problems with them.

     

    second, you want a switch with poe, so you don't have to power the cameras separately. i've used cisco's "small business" line of managed switches on numerous sites and always been happy with them. the sg300-10p is a great little unit - 8 poe ports for cameras and two uplink ports, all gigabit.

     

    third, your setup should work, *if* you're running an smtp server or some sort of smtp forwarding on your recorder. i've done this in the past on sites with a similar network layout: ran a small smtp service on the nvr and then pointed the nas and cameras to that for their alert emails.

     

    fourth, do yourself a favor and *don't* set the cameras to email/mms on motion detection.

     

    fifth, i wouldn't use vivotek or d-link cameras if my life depended on them.

    hello. we plan to install a CCTV system in our company, at least 8 cameras. I would like to know if we should use D-link or Vivotek cameras . however there are some restrictions or problems:

     

    1. the whole camera system would be on a different subnet, so not directly connected to our LAN or internet (for traffic and security reasons).

    2. Due to the extreme amount of data (8 cameras) i am thinking of a NAS system with 4 pieces of 3TB HDD in RAID 5 so 9 TB free space, on ethernet

     

    If needed, a 'server' would be installed with recording software and 2 ethernet cards, one is for this subnet, the other would be connected to the other LAN which we use for PC connection and to connect to the Internet.

     

    2 cameras would be in a production area where no recording is needed but live feed and the manager wants to see an MMS or a pic sent to his phone by email whenever he wants. (ok maybe 1-2 frame/sec recording simultaneously, but this is not yet decided)

     

    The other cameras would record in case of motion in 1200x800/10 fps minimum resolution and frame rate, some cameras at critical points at 15fps and 1280x1024 . we would use the NAS and gigabit LAN. is it enough? we want to store 8-20 days of recording.

     

    My question: is it possible to set up such system and what are the best types for it, vibotek or dlink? is the above described solution possible with this config/cameras (MMS, email, etc). note: the production area cameras are not in motion detection mode, they make live feed and the transmit it to mobile phone or email only if requested (or record 1 pic/s onto a folder and this image is sent to mobile when requested-equally acceptable solution.) please let me know.thanks
