I have 2 NVRs on the same router but don't want to work together
Mark_M replied to ggmaury's topic in Digital Video Recorders
What brand is your system? It's probably going to be achieved by adding the RTSP URL from the second NVR's channel output to a channel input on the main NVR. -
CCTV 4K WIFI Camera recommendations please
Mark_M replied to fourtytwo's topic in IP/Megapixel Cameras and Software Solutions
Good luck to you. I've found Reolink to have poor quality and doesn't let you adjust settings for better night performance. -
CCTV 4K WIFI Camera recommendations please
Mark_M replied to fourtytwo's topic in IP/Megapixel Cameras and Software Solutions
Also cheap cameras at a higher resolution perform awful at night. A good brand of camera will give a specification sheet. For 4k (8MP), you would want near 1/1.2" cmos or larger... not a tiny 1/3" or 1/2.5" cmos sensor. In Reolink's video you can see how the person 'ghosts' into the background at points. https://www.youtube.com/watch?v=Y6Oxhxk8lxM Ghosting happens with a cameras exposure is too long for the amount of movement. A typical reason for a CCTV camera to have a long exposure is because the imaging sensor cannot capture enough light to capture a decent image. You can help reduce motion blur by adding external IR flood lights, but that adds extra power consumption. -
IndigoVision Control Center - How to use a 3rd Party NVR?
Mark_M replied to DaveFix's topic in IP/Megapixel Cameras and Software Solutions
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.- 2 replies

H264 DVR boots up for 2 minutes then switches off?
Mark_M replied to quovadisuk's topic in General Analog CCTV Discussion
As tomcctv is hinting to, I also think it maybe a power supply issue. tomcctv is suggesting to unplug many devices so there is less power being used from the plug adaptor. Working for a while then failing is a sign the power supply is likely dying. -
Smart PSS can export as an MP4 and other formats.

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. A 16ch NVR with LPR/face recognition is $1,200. That's a lot closer to your budget thankfully.
-
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. https://ipcamtalk.com/tools/calculators/hdd/ 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.

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.
-
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.

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'.

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.
-
Yes, that can work.

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.

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