    The footage is seems good but only day time is poor to prove it general character is fine. And I saw all scene is located in China.

     

    As for you claim comply for most VMS i.e. Milestone.... I do not think its affordable compliance. Maybe let me check all conformant list in each one.

    I have saw the spec but you know only account on it not enough for it. and I noted some specification is not reasonable, i.e. IR 40M by 42 units of 5mm, its basically relative to amount o units but also how is emmitting angle. And power consumption only 270mA Max, wow they are superior than any supplier.

     

    Actually, this type I remember has some one complain about the quality in night time in the forum. And this type should be from China.

     

    Sorry for my straight words.

    Hi Mate,

     

    As you mentioned, overall is not key issue for framwork. You just deployed solar power generator with UPS, IR camera, DVR and wife / ( 3G/3.5G) modem. Then signal transmit to centralized station. Then you could remote and control on PC/NB even on cell phone. But I am here would like to recommend you some issue yu may care, you better considering equipping some lightening arrestor and surger protector when raining eason coming. Most damage is caused by act of god.

    Hello

     

    You may consider deploy two 16Ch at two floor. Basically, present DVR has built-in multi out, HDMI, VGI one or two BNC. Then bridge spliter 1 in two out to those DVR then you not only monitor at decentralized spot but also one more back up DVR in case of one unit is shut down.

    Hi Mickey,

     

    I think point is not only how quality are but also parameter programmed in camera. Basically, jewelly, golden, jade store is high challenge for most installer arround, especially where is full of spot light on those brighten and high bounce stuff.

     

    If you are fine i would like to recommend you one expert who is dedicated in this security as well as able to integrate POS text overlay to CCTV system. Most important of all who is located SA and now also expanding territory you there.

     

    So if you are available pls PM me then I would reply you and CC to him.

     

    Cheers.

    DVR manufacturer will provide you IP? It ounds magic, I guess you mean some DVR suplier provide Cloud, which is only way to support web browser view not for PSS or CMS.

     

    Are you bridge any router or IP sharing box, if you do you better Link router via Note book or PC by wired cable to check IP address and does it works then set up port forwarding at cetral management page of router. make sure both site of DVR and router is same IP address. Meantime also register DNS e.g. No-IP...

    Yes,

     

    Day time is pure good but night is poor. But even in high light, I do think so it would so bad for it equipped Auto Iris vari-focal lens.

     

    You could clean glass house to move all dust, it may cause bounce in front of lens.

    can some one help i need to build 8-16 ch HD-SDI system .i have some 700tvl camera that i need to add.also some camera over 250 ft long . I see there is 7fps dvr and some 25fps dvr record witch is good need any suggestion for me .what the difference real time record and 7fps. also i need to know about digital zoom on HD-SDI camera.

     

    Yes you need to Hybrid DVR for hook up HD-SDI and SD camera. Typically, realtime is defined @25FPS. As for Digital Zoom, there are two way to do, one is on DVR which has function to Zoom in and out. Sendcond is equipping HD-SDI camera which has featured digital Zoom and RS-485 port then bridge camera and DVR then you could manipulate.

    Hi all,

     

     

    could anyone help on this..

    why Nas storage cannot be used as a primary storage for survallance, what i could figure out is as below.

     

    NAS provides only file level access to a storage volume while DAS and SAN provide block level access. In surveillance, block level access is required

    by most systems, including Avigilon Control Center (ACC). As a result, file level access and the use of network attached storage is typically limited to applications with very few cameras.

     

    Please specify if any other reasons?

     

    Hello,

     

    You may check QNAP, NUUO who is dedicated to developing NAS for sureveillance, which also bunddled VMS for monitoring.
