Afternoon All,

I have an old analogue BNC camera that requires replacing. It is currently connected to a 4 channel Hikvision DVR with 3 other cameras which are working fine.

Question is can I replace this defunct camera with any branded BNC analogue camera?

This is the system I currently have
https://www.mightyape.co.nz/product/secure-homes-4-channel-4-camera-kit-1tb-hdd-1080p/28049094

Very old and antiquated I realise but cannot afford to upgrade the system as of yet.

One of the cameras I was thinking of as a replacement was

Or

Any insight or thoughts as to whether either of these would be a simple plug and play.

Cheers

Firstly, are you sure its actually 1080p cameras because scammy cheap ones will often say 1080 on the kit because that is what the HDMI output is.

Depends on the resolution, Hikvision have their own HD format, most of the others are one called AHD.

There are multi mode ones on aliexpress, look for one with an OSD controller on it as that is how you change the mode by holding it in one of the directions for several seconds. Also the OSD lets you configure the camera, while standing up a ladder with no way to see the menu other than your phone viewing the DVR.

Not all the same. But plain old composite video is 99% universal.

But 'HD over Coax' solutions by various companies are not always compatible. E.g. Hikvision's 'Turbo HD', Dahua's 'HDCVI', AHD.

The example of the camera with a PIR sensor likely adds an extra line into the video which is PIR sensor data. Some cameras don't even transmit as analogue, they transmit digital like 3G-SDI/HD-SDI.

Given budget constraints, is it worth replacing the coax feed to that camera with a Ethernet cable and associated iP camera and at the DVR end find a suitable Ethernet to Coaxial converter.

obviously you won’t be using the smarts on the IP camera but at least you know you have upgraded that single camera?

edit, those converters look cheap and simple to good and expensive…. But again, if it’s only the picture you need for now then it could be worth exploring…. You could always try sell the converter later…
