Yes! the garage cam is actually a 2132, I was typing on my phone last night and didnt realise I had mis-typed it.so no, its a dome and doesnt have a rain shield, tho the IR is starting to bounce off the rafter in the garage, it was a little worse before and I have moved it down slightly, but im sure you know yourself the smallest movement when tightening them up can make some difference to the focal point.

The build quality of the 2142 is noticably worse than the 2132, the foam round the lens is cheap and nasty on the new model.

Manually assign your pc/laptop with an address on the same range as the cameras, then plug cable from your computer into one of the camera ports on the nvr and type the ip address of each camera into your browser, it's the easiest way I have found to do it

so if my cameras are 192.168.254.2 , 3, 4, and 5
what would i put into the network settings in windows?
The ipv4 address on the nvr is 192.168.1.1
the internal NIC ipv4 is 192.168.254.1
and the gateway is 192.168.1.1


thanks

give your computer

IP 192.168.254.50
Subnet: 255.255.255.0
gateway not needed

then connect cable from back of computer into one of the NVR camera ports

open up a browser and connect to each camera individially, if you only have a 4 port nvr you will obv be missing one of the cameras for a short time whilst you have the computer connected.

http://192.168.254.2
http://192.168.254.3
http://192.168.254.4
http://192.168.254.5

If your nvr has recent firmware on it (and it really should to keep it secure and reliable) you just enable virtual host. Then browse to the nvrs ip address on the local network on port 65001 to 65004 to access each cameras web page.
You MUST type http:// at the start for it to work. For example ifyour nvr is on 192.168.1.10 and you want to adjust camera 2 which is on the nvrs poe side at say 192.168.254.3 just type in to your browser http://192.168.1.10:65002 and the nvr will let you configure the camera from your normal lan.
Why is your gateway the nvrs address? It should be the routers address.

[wjwren]

MGD - thanks that has helped a lot.

this is what I have on my NVR - is this incorrect? The talktalk router is 192.168.1.1 if that is relevant..

[OldGermanHeaps]

That looks corrwct, what you posted further up the page was your nvr was on 192.168.1.1 and your gateway was 192.168.1.1
On your laptop browse to 192.168.1.7, log in, go to advanced network settings and enable virtual host.
Then in your address bar try http://192.168.1.7:65001 you should then be able to access the advanced image settings for the camera. Its a good idea to update the firmware on both the cameras and nvr. On the cameras in particular there was a bug causing poor night vision below v5.3.8

That's a great bit of knowledge right there!

[wjwren]

cheers for that, it's worked a treat!

How would you deal with the below - where the number plate is bouncing the IR off it and making it too bright? There are no lights on apart from street lamps.

[wjwren]

also is 3.4.2 the latest firmware as when i click on update it says it's the latest - is this correct?



No idea why this is upside down!

[OldGermanHeaps]

to read number plates at night you need to carefully balance exposure speeds and gain settings until you can read the plate clearly, and the plate wants to be filling a far greater proportion of the screen than it currently is. while the plate will be readable the rest of the image will be dark and illegible so you will need a second camera to give an overview of the scene at the correct exposure. you can buy specific cameras which can read plates at night while still having a good overview of the scene but you are talking £450+ for a 2 megapixel one. reading numberplates is one of the most misunderstood areas of domestic cctv, peoples expectations far outweigh what is possible in reality.
if you just mean the bright reflection is drowning out the area around it you can switch on hlc. from the image that looks like a 2142, the 2342 is much better at night.

[OldGermanHeaps]

yep. latest camera firmware is 5.4.1

[wjwren]

It's a DS-2CD2142FWD-I - why is the 2342 better?

thanks

[OldGermanHeaps]

The reasons i states above, the 2142 has a problem stopping the ir reflecting on its own perspex, made worse by thepoor foam seal and poor dispersal pattern of the ir leds. The 2342 has the lens in a copletely different sealed glass lens, not plastic and the ir led is totally seperate, and features optics to give a nice even spread of ir.
the exir is a great technology.
The more reputable hikvision authorised distrubuters point out that although the 2142 is fully weatherproof they only recommend it for indoor use where strong nightvision isn't essential.

i bought a hikvision turret 4mp friday and swapped it out yesterday. The difference at night is amazing. A lot lot better. No grain and a clear picture. I also purchased one of these below but to be honest im not sure I need it as the image is already so good.

[stirling37]

good thread i have a hikvision set up at my house and i will need to look at what cameras i have (all of the dome type) but i have one which when it was sold was good for close up but its very grainy at night been more so this year, day time they are all clear. are these cameras all the same in terms of power etc ie can ust plug it in to the lead that i already have there?
ill have to google the turret cameras you are all suggesting.

[wjwren]

i have 2 bullet, 1 turret and 1 dome (all hikvision 4mp poe) the turret wins hands down at night. They are all pretty much the same in daylight. Im still having issues trying to access them via my phone if there are any experts on here?

[stirling37]

is this the camera you guys are referring to?

https://www.amazon.co.uk/gp/product/B017C4WCES/ref...

if so then id be interested if it can just be used with my exsisting hikvision setup, i have the two cables that it connects to or are these a different type of connection?

[wjwren]

yes but mine is the 2.8mm lens. They run on Power over ethernet (poe). Do you have a POE hikvision recorder? You only need 1 cable to the camera, an ethernet cable.

ah thats a shame, no i my cameras have two leads like s cables which twist and lock in the back of the recorder and the same with the camera.

ill try to put some pics up when i can of the images at night, daytime no problem at all.
