New nvr system

[gaz1234]

Hello
I’ve had my house cat6 wired for cameras.
My friend who fits cameras etc reckons the darkfighters would be sufficient.
I’ve differing areas and depths to cover so will these do that or should I speed up different kind of hik cameras accordingly?
Presumably there’s a tool out there that can help and mixing them will work with the nvr?
These are what I found/recommended

HIKVISION 4K DARKFIGHTER IP POE 8MP DS-2CD2386G2-IU CCTV CAMERA SYSTEM NVR ACUSENSE KIT

your friend is familiar with your property.

in terms of suitability it depends on what you want it to do.

Cameras should be specified for the job they need to do. That may result in the same camera for all locations or vastly each one with a completely different specification.

 

[gaz1234]

Not overly. Seen it once, briefly as I’ve only been here for a few months.

I want high quality cameras and 6x cameras so I trust an 8 channel? Lots of storage, say 30-60 day retention

Do the hiks have the ability to mix the cameras

I want high quality cameras

That could mean anything.
One persons high quality is the next persons substandard junk.

Lots of storage, say 30-60 day retention

Storage of what?
24/7 continuous recording of all cameras, or just recording the intervals with something actually happening? Or some combination of those?
Then there is resolution, bitrate and compression to consider.

Do the hiks have the ability to mix the cameras

Most can be used in various combinations, even with those of other manufacturers if they support ONVIF, which most do.

6x cameras so I trust an 8 channel?

An 8 channel NVR will support up to 8 cameras, so 6 could be used with it.

I’ve differing areas and depths to cover so will these do that

What areas a camera will cover depends on the lens fitted to it. Different lens = different field of view.

This video might explain how I would use DORI for the type of image I want to see and at what distance away from where the camera is mounted.

Light is important wrt to colour and clarity both day and night.

Darkfighter technology for example utilises low light conditions to get a colour image but switched b&w images using infra red.

Color Vu is similar for 25/7 colour but uses white light to help the camera maintain colour.

There are options hybrid that can use ir and white light.

FPS frames per second, the higher this is the less blurred the video is, in terms of cameras the higher the resolution, the lower the frame rate is likely to be on the same camera at max capability for that resolution, as resolution and frame rate represent data.

As for what’s best, depends on what you need it to do.

so if you have a terraced house, that has a pavement outside it in terms of resolution you can get away with 2MP camera with a 2.8mm lens(privacy issues aside)

But that same terraced house house is likley to have a bigger back yard, so I might want a higher resolution camera with a similar field of view to get the same DORI outcome at the perimeter of the garden/ yard.

In terms of 6 cameras and 8 channels it’s not as simple at, if the cameras were 8MP then possibly not, but each NVR has a capability, with different types of compression.

so you need to look at what the NVR can process.
As for storage 30 days is a lot 60 is some serious space, so you may need large hardrives and multiples of them. Budget then comes into play.

So we are back to what do you need the camera to do.

The biggest mistake made is buying a kit with x number of the same cameras in it, without taking into account what each of them is required to do.

Lots of threads on here alone about cameras.

See under and over spec systems all the time, over spec is extra cost, under spec is a waste of money as you buy again.

Caution, NVR capabilities are governed by bandwidth, number of channels encoding and decoding capabilities.

Just because you can add 32 cameras to an NVR it may not have the capability to process all 32 channels at 8 MP@25fps

It might be capable of 8 cameras @ 8MP or 16 @ 4MP and so on.
This catches a few people out as an NVR being sold might say 8MP 16 channels but it could mean maximum 16 channels and maximum resolution on any given channel is 8MP.

To be fair Hikvision NVRs do have this information. on there spec sheets.

Pm me if you want and we can arrange to have a chat. Think flameport makes some very good points.

High quality, isn’t the way I like to think, value for money is.

So 1MP cameras Detect quality, at a few meters is probably okay
But at Identify quality 1MP at a few meters isn’t going to cut it.

But 8MP cameras at detect quality at a few meters away is over kill

I put in a Hikvision system, seven cameras of various types to suit locations. All are 6 or 8 Mp. The 8 channel NVR was not enough, frequent momentary freezing on recordings. I had to replace it with a 16 channel NVR

 

[gaz1234]

Some cameras take up more resources right?

 

[secureiam]

The problem is the way the industry works unfortunately.

Every NVR/DVR/HVR has a specification

8 Channels on a 4K NVR doesn't mean all 8 channels are 4k @25 fps when it comes encoding and decoding

To make matters more complicated, some 8 channel NVRs are capable of this with very similar looking names.
You have to check the model and the build, for example some nits have a (B) and this means they have a different specification to the ones without the B, not all retailers are cler in which model they are actually selling.

You must start with getting the right cameras for what you need it to do that's within your budget and you can then look at what your options are for the NVR.

 

[gaz1234]

Going for the following cameras.
Just want to check what nvr will run them?

1x

Reolink systems are also well thought of. They have plenty of 8 channel NVR packages.

 

[gaz1234]

Ha yes I know them well and are pretty good. Not sure they are quite as well built
