    360 degree 12 megapixel cameras

    I can’t comment for exactly your scenario but I have installed over 32 2mp h264 cameras on a system of less spec and had no issues. Even if you equate 12mp cameras to 6*2, total is only 24. I’m assuming your going to be using GV-VMS?. Install a decent video card and I wouldn’t have thought you would have an issue. I would install at least 4x8tb but would probably put in 4x10tb. I used to use geovision all the time but they seem to have lost their way so don’t really use it anymore. Software is kind of dated compared to alternatives.

    Hikvision wiring issue - help!

    I was just trying to balance the numbers because this recorder will take a maximum of 16 cameras including ip/tvi/analogue but not over 16 so I was verifying that you didn’t have any ip cameras using available slots. And by testing them at the recorder you were inadvertently disconnecting cameras to test these thus freeing up available slots so that they worked. But as you don’t have ip cameras attached then I say again, hookup a local supply and this will eliminate both the cable and your main supply from the equation.

    Monitor Quality

    A frame rate of between 10-15 is fine for most use cases. To put it into perspective it takes about 6 FPS to catch someone stealing something off a supermarket shelf.

    Hikvision DS-7608NI-K2 adding a speaker

    If hiks a better solution, please post a link, I’m sorry but I’m not aware of hik manufacturing a speaker product? There is a powered PA solution, a speaker with a built in amp, built still needs power, so extra wires. I suggested that but the op decided to go with the amp solution. If there is an all in one solution that requires no extra cabling then great, I would like to know for future reference. Please provide a link? I’m merely having a discussion which is what a forum is for. The application is clear, it is for remote use, with at least 5 cameras so chances are he isn’t putting them all in one room. He calls it a property, not usual talk if it was his home. I may be wrong though.

    Tom can you provide a link please as I’m not aware of a hik speaker and mic?

    When did I ever say it wouldn’t work. I pointed out you could extend the cable however what you could do and what you should do are two very different things. In no case and I mean no case are PC speakers ideal. First of all pc speakers are stereo, the output on a recorder is mono, only one speaker will work without some alterations. Typically leads are prefixed with a 3.5mm jack. The output is RCA, again you will have to cobble something together. Extending cable is again messy. If your installing remote speakers, install speakers designed to be installed, e.g wall mountable with terminals at both ends. Install speakers you can expand upon. PA speakers are designed for public address it’s in the name, they are designed for voice applications. I’m not starting an argument just pointing out fact. I’m sure the people looking on here are looking for sound professional advice, not a hobbled together solution.

    Monitor Quality

    It makes absolute sense installing a higher quality camera than the monitor because when you use the digital zoom function to see who just robbed you then there will be more pixels within the image so it will be clearer when enlarged than the equivalent lower resolution camera. Remember ultimately this footage could be required as evidence, so the clearer the better.

    Which security camera to purchase?

    Cortian is right, but let me clarify my opinion. Wifi can work in ideal scenarios, good quality WiFi for instance, ruckus or Cisco aironet or equivalent. But rarely WiFi is ideal. With the number of factors and variables that can occur it can be more problem than it’s worth. Even with the best WiFi, you have to remember that WiFi is a two way conversation. This is where the first issue comes, in my opinion after using many WiFi enabled cameras, the WiFi part is weak and substandard with small gain antennas. Second devices such as these require at least a -65dbm signal level to be able to operate properly. Rarely is this achieved across an entire site and in every corner of every room. So signal may not be strong enough in the optimum position for field of view. Interference can make and break your installation. You have to run power anyway so why not just run a cat5 and use Poe. Likely hood is your not going to be watching the cctv all the time, so do you want to risk a blip in communication that misses something important that can be caused by something as simple as someone walking in your hotel with their hotspot enabled on the same WiFi channel.

    Tom is Right you need to be looking at professional cctv solutions, not your off the shelf add on solutions. All comes down to budget, how much you looking to spend? Also never go wireless unless absolutely necessary , even with enterprise WiFi the results can be unpredictable.

    If only they provided a calculator like Axxonsoft??. I wouldn’t have thought you would have a problem but I would recommend using an nvidia card and GPU decoding. I would contact them and see if there is any kind of guidance for specifying hardware.
  11. Did you manage to test direct with and Ethernet cable?

    Because he wants to someone to hear him when they enter the property. PC speakers are designed for sound output from a PC, hence they usually have a short lead and 3.5mm jack. They are not designed for distributed audio throughout a property. So I say again, unless they are standing next to the recorder, what good are they. Potentially you could extend the speakers but again they wouldn’t be designed for mounting on a wall or recessing into a ceiling. Menorcarob, If it’s something like this it will be fine, just don’t exceed the total wattage for the speaker outputs, when using 100v line you add the wattages together. So this amp should be good for 2x15w 100v speakers for example. https://www.inta-audio.com/eagle-p650b-30w-100v-line-mixer-amplifier-p9157 Also make sure the speaker cable is double insulated. This is 100v after all so treat it with more care. If in doubt you can buy 100v line cable.
  13. Also note that the HUH can also take more additional IP cameras if desired. So the long and short of it is that the HUH is the more capable recorder.

    Not sure how pc speakers would apply to this application unless you wanted to talk to someone while they were stood in front of the recorder??? The professional solution as I said is distributed audio using a PA amp and typically 100v line speakers. These can then be scattered around the property and daisy chained together. This will only cover being able to speak to them, if you want them to speak back or listen to what they are doing, you will also need to install mics. Personally I find it easier to install cameras with the mics built in but if that’s no longer an option then something like this. https://www.systemq.com/Product/CCT619 However if you used POE to power the cameras, you will need a separate 12v supply to power them. Tom is right about the siren, use one of the relays on the back of the recorder. You will also need a 12v supply. I would suggest installing a 12v box supply for mics and siren.

    Hikvision wiring issue - help!

    Hi Macklington Just help me understand the numbers, so you said you have 3 camera's not working, but you also say this recorder has 14 other cameras on it. Its a 16ch recorder, can you please clarify? Does it include any ip camera's. Whats the breakdown of the camera's attached? when you say similar model, does this mean to say the ones that do work are different in some way?
