    Is there a way I can use a third party NVR, such as Duhua, to record them but still use Control Center for monitoring and playback?

    I do not know for sure if this would work.

    Motorola Solutions acquired IndigoVision in 2020.

    Before this time, some of the cameras were just rebranded Dahua cameras.

     

    I do not think IndigoVision used Dahua NVRs. So likely playback from Control Centre would not work.

    What brand nvr should i be looking at and model number ?

    I can suggest all required devices from a brand I know... But the total is around $17,000 for 30 * 8MP cameras with face recognition, 2 * LPR and a low end $2,600 32ch NVR that supports face recognition/LPR.

    Realistically, $20,000 total for cabling, junction boxes, HDDs, switches.

     

    Tips for you to get closer to the budget:

    • Don't chase facial recognition.
    • LPC (licence plate capture) instead of LPR (licence plate recognition).  LPC just means the camera captures a clear image of the plate. The camera/NVR is not automatically reading the text, it is a manual process to read the text.
     
    A decent 32ch NVR costs $1,500.
    $2,600 for one with capability to work with LPR/facial recognition.

    But I only need at least 8 for now and 8 for the future.

    16 will work

    A 16ch NVR with LPR/face recognition is $1,200. That's a lot closer to your budget thankfully.

    LPR and Face Detection.

    Budget Less than $1,500 USD

    A 16ch NVR that does Face recognition and LPR support is about $1,200. The LPR cameras are about $600.

     

    And why do you require 4K?

    8MP worth of video is a huge amount of data.

    103TB for 30 days worth of footage... that is a VMS solution worthy of server equipment and double that for raid configuration redundancy.

    Not to mention that 4K is a waste unless it's a $400+ camera with decent imaging sensor.

    Cheap 4K cameras just produce a blurry mess at night capturing moving objects.

     

    Seriously reconsider what you want this system to accomplish.

    4K is hyped beyond realistic outcomes, you don't need 4K to capture usable footage.

    Thank you we agree. But we cannot use 24v. is there any other device supply 12v. for example.

    Does the system need to work at night?

    A batteries voltage drops as power is drawn from it.

    Once the battery goes below 12, the 12v regulator will stop working and your cameras will turn off.


  5. Most charge controllers do not output exactly 12v, as you have said.

    This is where you would use a 24v solar system and a voltage regulator device set to output 12v.

     

    Using a 12v regulator device on a 12v solar system can be done, but it will turn off if the input voltage drops below a threshold, e.g. 12.5v (refer to the specifications).

    The input on these regulators always has to be higher than the output voltage.

    research on the subject of wizsense, SMD plus, acusense, AI, etc. but I'm still not very clear about choosing one.

    Different brands have their own names for smart detection algorithms.

     

    SMD and Wizsense (a Dahua brand term) have some differences.

    SMD is a step up from standard motion detection, to 'Smart Motion Detection'. Wizsence is for analytics like Trip wire, intrusion, etc.

    For most people, SMD is enough. It just detects if there is a person/vehicle moving within the video.

    Wizsence is detecting a person/vehicle moving past a certain boundary or entering/exiting an area. The main term for this is 'IVS rules'.

     

    Hikvision has their version of Wizsence called 'Acusense'.

    Hello.

    Can someone please please help me enhance a car plate in a photo captured from a CCTV. It's this Mercedes A class.

    Thank you so much

    Sadly it is not like the movies.

    Data cannot be made up to 'enhance' the resolution.

     

    I suggest for a car park that you get a camera with the correct focal length aimed at the entrance.

    -has clear as day night vision up to at least 20ft

    -last but not least INEXPENSIVE

    Good quality night vision is $200 and above from my experience. That's above what most consumers are willing to pay.

    Then factor the cost of an NVR and cabling. Around $1200 for 4 cameras and a low end NVR.

     

    I use Dahua Starlight. There's also Hikvision DarkFighter, Uniview LightHunter and Axis Lightfinder.

    Reolink/Swann/Concord/NightOwl/SecureView have a reputation for poor quality at night vision due to longer exposure time needed to compensate for a low quality camera sensor, and a longer exposure means objects moving turn to a blur.

    i am looking to split an network point to run 2 x IP cams off it i will divert the connection from the existing network switch into my NVR and split the other end using a RJ45 splitter

    So a mini POE switch? Like this mid-span one?

    https://www.amazon.com/Loryta-Extender-Repeater-Ethernet-Splitter/dp/B07RQ569MF

     

    There's also others labelled as 'POE extenders' with two (or even 4) ports.

    This is a Chinese one from AliExpress. Does the exact same as the Amazon linked one above.

    Ok then the best way is to use two power line units …. It’s cheapest and best way

    A POE powered and 2-port POE passthrough switch is plenty for most scenarios like this.

    Hello there we would like to change boot up logo of xvr . We need help and we ll help too . 

     

    Logo's are usually compiled into the full software.

    I do not know any company that would just give you the uncompiled software.

    but when I look into options, everything is cloud-based or requires an NVR to operate.

    AN NVR's main job is to pull video from an IP camera to save it. Usually there's extra management features too for the same brand.

     

    But IP cameras can work independently.

    Almost any brand of camera will be able to be used with another system.

    For a DIY scenario, a camera which outputs an RTSP stream would be enough. That's basically 90% of the market.

     

    The cheapest Dahua camera I have, has functions for motion detection and saving clips over FTP to a network location.

    NVR does support SSD. In fact, SSD is better than HDD when it comes to reliability, uptime, high-quality video, and durability.

    False information.

    CCTV HDDs are designed for a purpose. They are designed to withstand constant writing data to each memory block.

    SSDs not designed for cctv will not last more than a few years with constant data being written.

     

    Claims of improving video quality is also false because the storage device is just to store data, it does not alter the video in anyway.

    Good day, I have 12 cameras on my home video surveillance system, they run off two power supplies, the one was recently replaced and the 4 cameras that run off this one has horizontal lines moving upwards on the screen. This only happens at night and not during the day. The lines are 4 on a screen at a time. Anyone encounter this problem before and can offer advice?

    Every time I have encountered this it is because of a faulty power supply or grounding issue.

    I had this file come across my desk

    0758-24may21.001cam1(1).srt

     

    its not a subtitiles file, anyone know what the player is, they send the file and no player  (the story of my life)

    .srt is supposed to be a captions file. Just standard text.

    As tomcctv stated, often used in point of sale systems (overlay transaction data of the cash register on the video feed).

     

    Try opening with notepad in windows and see if it opens as a text or gibberish.

    If it opens as gibberish then the system has used .srt file extension with some other file format.

    Lorex is not a rebrand dahua 

    lorex is dahua and is probably one of the safest places to buy a dahua system and have full support

    Yes, same company and usually same products under another brand (Lorex) without the 'premium' features of Dahua analytics.

    Dahua IMOU range is a separate production line (probably similar internal components).

     

    Agree to the point about full support.

    lorex …. Now owned by dahua (your old q-see) has a lot of choices but you can look under dahua brand for more options 
    take a look at dahua TIOC system some good functions and alerts for home use   

    Lorex, Amcrest and a few other rebrands of Dahua will be of standard Dahua quality for their low-end line.

    Dahua original cameras tend to have all their analytics/Artificial Intelligence functions.

    Those sort of functions is commonly IVS rules. IVS is the camera trying to work out the difference between a human/vehicle and then triggers an event when they cross an imaginary line. Far better than standard motion detection which triggers on a bug attracted to the camera.

    Example image is from Dahua with a tripwire IVS rule. Car crosses the line and it does something (notifications, records, sounds an alarm).

    this could be a problem if you go cat5 option 

    (iP system)

    Dahua does have system that use Coax, however it is best to use Ethernet cable (Cat5, Cat6).

    Can you use the coax cable to pull an ethernet cable through your roof space?

  17. That web GUI looks like XMeye cameras.

     

    System > 'Net service' has the menus for Cloud and DDNS.

    However.... cloud stuff on these is P2P with XMeye's servers. Anything of P2P is not that secure.

    DDNS is for port forwarding a device and having another DDNS service keep track of the IP address your router changes to. Otherwise you can pay your internet provider for a static IP address. But this is also not secure.
