Whats insanely bugging me now is that with it suddenly working I literally understand even less, how did it suddenly start working after a long pause, is there a very long boot process or does the NVR do a refresh every half hour or something. How do I plug in a second one of these and make it...

Hi, It gets more curious, I left it for an hour and when I came back it shows its working but says its plugged into a different port than the one I have it plugged into. So I have a picture but what is happening here? here is the link to the camera on AliExpress...

Hi, Thanks for the reply. I have Dahua cameras and they just plug and play so this non Dahua camera is new territory for me, adding something that does not immediately recognise the NVR and visa versa

Hi, I purchased this pin hole camera hidden in what looks like a burglar alarm sensor How do I make this work on my NVR? It is a 5mp Poe, IR and audio camera. Currently set to 192.168.1.10 I surmise I need to set the NVR channel to ONVIF but not sure of the sequences to go through. Can...

Multiple alarm sirens both inside the house, instead on just one, and flush mounted sirens under the eaves outside the house, just raise the racket inside so that it is uncomfortable and upset the neighbours with multiple sirens outside. All this in addition to the box with a flashing light...

Ok, with 30+ years in alarms I have seen a lot. I have seen externals filled with expanding foam or water, PIR’s with plastic sheet inside them (more intelligent, inside job) and others with components ripped off the board, Dumb crim), roller doors lifted on the opposite side to the switch so...

I have quite a bit of experience with alarms, not so much at all with cameras let alone their AI. We are lucky that burglars are dumb but they have learnt to wear hoodies here in NZ so the need for pin holes mounted low down is real, these pin holes look up at or level with the face. But yeah…...

Hi, Look into what Yachties use, they have an inverter off a battery bank, charged by solar, with backup charging off the alternator on their diesel. (More than 1K cost I guess) You can investigate buying a wrecked yacht for less than $1000 and get all the gear you want. Also, if you are away...

Ahhhh, My pet peeve LOL ….. Most alarm systems are specified by and or installed by amateurs so while they are the most important initial defence they are often easily thwarted, fortunately most burglars are equally amateur (eg. cut the Phone line, but most are not monitored, and fill the...

A telecoms friend has removed, for upgrades, such UPS from large commercial buildings, they dump them. I suggest that the second hand route would be advisable. They use them for phone systems and PC networks Chase down phone installers and Large commercial network maintenance teams.

Hi, Can I reset this NVR or is it a lost cause? I found it second hand for $20 because it offers no access without the password. I am wondering if I could recover it to factory settings and enter a new password? (Has a power supply and HDD so that was worth $20) 1. Do, or can I, run a...

Hi everyone, I am about to buy an NVR5216-16P from Andy but then this powerful unit came up on our equivalent of eBay here in New Zealand. It is brand new in its sealed box. My actual situation is that I am at around 8 cameras (5442’s and 2431’s) but it is 5 acres with a home plus...

Hi, I have just seen an NVR5216-16P-4KS2E (note the “E”)for sale on Facebook market place, second hand and never used due to failed project.. (Coincidentally my new one from Andy@empire is in transit and arriving via FedEx on Monday) Anyway, I read the huge thread on these and know there is a...

Hi Thanks for this, Would you add a WD Purple or Seagate Skyhawk to this old PC or just go with any drive? There are claims out there that you really should use a dedicated surveillance drive.

Thanks Can you refer me to a link that explains this? I would like to read up on it and study it. It sounds like it might be the next stage after I complete my current learners steps, nothing wrong with learning one and then stepping up.

Great point! So I would need to update my router to 1GB? What about the Poe switch? Should I get one with a 1GB uplink?

And your comment is precisely the rabbit hole I am exploring. I want a great resolution and am aware that FPS and bit rate limit even great cameras. I would rather spend $1000 (our dollar buys 60 cents US) on a capable NVR that will kill it versus $400 and feel limited. Hey, I am going to...

Thanks This is exactly what I was thinking but as I have a very technical mind I like to understand “why” and how to calculate it……. Its strange but I like to understand the workings and then i feel comfortable versus just fit a box. Its like I need to know “why” otherwise I feel...

Thanks What I found was that the 4108-4KS2 was limited to one or two High res (4K or better) cameras due to bandwidth of only 80mb/s (unless you use 8 low res cameras). This means that the NVR 4208 -4KS2 with 200MB/s incoming bandwidth was still a bit limited if I added better cameras. This...

Hi, I see that as the cameras increase in MP you need to have an NVR capable of receiving all this increased volume of information/bandwidth. The NVR4108 series has 80MBS incoming bandwidth, the 4208 series has 160 MBS incoming bandwidth and the NVR5216 has 300 mbs incoming bandwidth. Yes I...

Hi all, some help would be appreciated for a neighbourhood meeting next week. Background I live in a semi rural area on a 3.5km long loop road so there is only one point of entry and exit. Across the road from the entry is a small private trotting club and we can potentially instal a tower or...

Old brand Closed down and few records on internet Any known issues with this camera? I have a new one here that someone never used (about 5 years old) Apparently fell appart in the post, heat sink fell off and some screws fell out so he just binned it rather than put in a clients house. It is...

Hello, Why is a 1/1.8 in the T5442T camera bigger than 1/3 and 1/2.8 on other cameras? Can you explain how this measurement works and how to use it to calculate the actual area of a sensor? I like to understand the specs I am reading

Thanks - yes I did consider this, the threads on changing fans are interesting and I am still reading them. However quiet is a big deal for me.

Hi from New Zealand, Found this forum a few days ago and am stunned at the knowledge base! I consider my self fortunate to have found you guys. Needless to say I am avidly reading ... including that 50 page thread on the Dahua NVR5216 Not a complete newb to security, 20 years ago I had my own...
