    Installing random camera from Aliexpress on a Dahua NVR4104-p-4ks2

    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...

    Installing random camera from Aliexpress on a Dahua NVR4104-p-4ks2

    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

    Installing random camera from Aliexpress on a Dahua NVR4104-p-4ks2

    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...

    Which UPS for 24 hr CCTV backup?

    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...

    Which UPS for 24 hr CCTV backup?

    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...

    Which UPS for 24 hr CCTV backup?

    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…...

    Which UPS for 24 hr CCTV backup?

    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...

    Which UPS for 24 hr CCTV backup?

    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...

    Which UPS for 24 hr CCTV backup?

    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.

    Hikvision NVR Password lost - NVR DS-7604NI-E1/4P

    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...

    Is the NVR5464-16P going to be too complex for my home use

    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...

    How do I check to see if a Dahua NVR5216-16P is the early model or the later version? (Version1 or Version2)

    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...

    How much bandwidth does a particular camera use - How do I calculate it?

    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.

    How much bandwidth does a particular camera use - How do I calculate it?

    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.
