    Hello,

    I have a Hikvision IP camera with a solid state relay output. This allows small amounts of voltage to pass though the open contact which is ruining a planned integration to an electric strike. It is enough voltage to hold a relay coil once it has been opened. I have tried resistors or diodes, but then the voltage drops too much to trigger the coil.

     

    I have made this work with various access control panels with a dry contact input. For some reason these systems are not as sensitive to small amounts of bleed. Does anyone know of a dry contact triggered relay? Currently I have this set up with an Altronix ACM4, but that is too big and total overkill for such a simple thing.

     

    Any help or comment appreciated.

     

    Thanks,

    Hello,

    I am researching two options for a live stream. I was wondering if anyone had any experience with this? This is just a live "animal cam" for about 50-60 unique visitors each day.

     

    Option 1 - Embed MJPEG Video at D1 from my Hikvision DS-2cd2012 into a web page.

     

    Option 2 - Use a hosted service such as YouTube Live or UStream.

     

    Before I go down the research hole, I would love any pointers anyone has.

    Thanks,

    Seth

    Has anyone ever done this? I have a client who has 3 PTZ cameras which just swing from side to side in the parking lot. There is no operator for the live view.

     

    In theory, couldn't a fisheye lens outdoor camera do this same function without motoring back and forth? I know that the camera would only be for a general overview, but that is what they are getting with the scanning PTZ.

    I have set up integration demos on virtual machines for many of my access control customers, so the install will be pretty straightforward.

    Client will have a couple VMs on physical machine, but has promised to allocate adequate resources.

    Customers IT department is windows certified, and proud of it. I don't even want to rock that boat by trying to convince them on Linux.

    Main issue is the client reads the specs for the proposed server and says, "I have all of that available, can we just install software?"

    Exacq kinda supports virtualization, but not this configuration.

    I will have to ensure a nightly data dump for backup, but I cannot think of any major downsides which canot be quickly addressed.

    Hello,

    I have a client who would like to run an exacq start system with 15 cameras on a virtual machine. Customer's IT department is on board, and they will provide virtual machine and have ample resources. They want to virtualize Exacq Start, not run Exacq virtual, as the IT department does not want any Linux systems to manage.

     

    Have any of you done this for a medium sized business? Any headaches you have experienced that you would like to share?

    II purchased a FD8135H to use as an edge recording device in an Exacq system. Documentation here:

    https://exacq.com/auto/specsheet/uploads/exacqVision%20Edge-Vivotek%20QSG.pdf

     

    The problem I have is that firmware version 0202c does not have the VDAP application available in the applications menu. Exacq Edge was tested on this camera with Edge firmware 0201a1. Is it possible to get a copy of this firmware?

     

    I have contacted Vivotek, but I was hoping to work on this over the weekend. Any help is appreciated.

     

    Thanks,

    Hello,

    I am looking for mid range vandal resistant domes which have enough room for a balun in the back box. Everything for this install will be surface mount, and the customer does not like the look of an additional box next to the camera. They want to install with baluns because they may want to switch to IP or a hybrid system. There will be 2 WDR domes and 6 IR domes.

    I was thinking of a Clinton VandalX Series

    or a CNB

    Does anyone have experience with these models or a similar project?

    Old post, but I do have an opinion.

    I have installed their commercial systems for a condo building with a very tight budget. User interface is clunky, network is slow and support is OK. There are lots of little hidden "gems," such as the inability to shut the system down. Tech support says to just unplug it. That was when I knew I was in trouble. For the money, I would rather work with Bosch or Speco Tech.

    Any recommendations for a low end IP camera with SD recording. Mobotix is out of my customer's price range.

    Here's the skinny:

    Customer has two entrances to monitor. Up to 3 staff members will view the cameras via browser interface. I would like to offer motion based recording or snapshots for the entrances as well. Needs to be day/night or have IR.

     

    Any help or advice is appreciated.

    So, my customer wants to install a camera in their elevator. I have provided pricing for camera, DVR, etc, but left the elevator cabling up to the customer's elevator company. Turn out that they cannot provide UTP, or STP cable in the elevator traveller, nor will they give up a spare pair.

    Elevator customer is offering to install, at an exorbitant cost, a new traveller cable. Choices are four stranded shielded 20 AWG pairs or four 14 AWG stranded cables. I may be able to get an RG6 installed, but it will cost about $1,000 more than the stranded wire.

    My issue is the high capacitance with shielded cable, or noise with non shielded cable.

    Passive balun, Active Balun?

     

    Any advice? I was hoping that the elevator company would be a little more helpful.
