    Help with video power balun

    The distance the power travels through your baluns will depend on a few things. One is the power requirements of the cameras which will be 12v and 0.55amp based on the information you have provided. The other is the thickness of the cable you will be using to transmit the power as a thinner cable will lead to more volt drop over the run of the cable. The packaging on the baluns provides some information on this for you. E.g if you want to run a 12v, 0.5amp camera (yours have a slightly higher amp requirement) over 24 AWG cable for 100m your power supply will need to be outputting 15.5 volts as over the length of the run it will drop to the 12 volts your camera requires. The general rule is the longer the run the less voltage you get at the camera end and you have to compensate for this by providing more volts at the power supply end.
  2. I think this will be because the NVR is trying to access the sub stream of the cameras when in the grid view. It will be using the main stream when the camera is full screened. I would log onto the camera using a web browser and see if you can turn on the sub stream as it sounds like it may be off at the moment.

    Help with new cameras

    Always check are the cameras ONVIF, which means it can talk to each other. However, it can only guarantee to have an image, not any other function. Don't really recommend people to mix recorder and camera with different brands, it usually causes issues. Only if you've spoken to the supplier first and make sure it all works. I would say, speak to the shop where you bought the cameras, see what they can do. God bless, man

    Maybe you can have a look at some standalone cameras. Check this battery camera first. I think it would meet your requirement.

    Hi. If you are looking for the camera specifically for car number plate, maybe the NPR camera is the one for you. But I don't think you would like to go there. The price is a little bit too high. I would suggest the 4K SPRO camera with Starlight tech. In this case, the face can be identified clearly even in the night. And it also gives you high resolution to room in for the number plate & any detail you would like to see. Furthermore, the DVR also has face detection/motion detection to push notification to your device. It should help you stop the crime. Hope this is helpful : )

    Power supply and splitter

    I think what you're trying to do will work. supply 5 amp / 4 outways spillter = 1.25amp?? This part is correct If it's definitely a 5 amp this PSU will do the job.
  7. The account that is locked is not on the DVR itself, it is on the cameras which is why everything you have done has not resolved the issue. Depending on the age of the cameras the username and password could be admin and admin. If the cameras are from the last 2 years or so the cameras would have had to have had a new password set on them when setting up for the first time much like you had to do on the DVR after defaulting it. I would suggest trying to log into the cameras using a web browser on a laptop as you may get the option to reset the password from there.

    I can't decide which camera to get

    I have two options for you to have a look. 1. SWWHD-INTCMSOLSTD - Swann 2MP Wireless Security Camera Kit with Solar Panel & Outdoor Mounting Stand 2. CS-C3A-A0-1C2WPMFBR - Ezviz 2MP C3A Battery Cam I think both of them match most of your required and it's stand-alone camera, it means it's all pre-made.
  9. In this scenario we need to get a proper idea of how it is cabled. From my understanding it is: PoE switch - 100m - PoE extender - 100m - camera If this does not work but the below does work it would indicate an issue with the extender or potentially the second run of cable being over 100m. Poe Switch - 100m - camera

    Add remote NVR Cams on local NVR

    As far as I’m aware this is not possible...

    Best value CCTV

    I think it is very suitable for you to have a CCTV Kits. It's all set and the price would be cheaper as well. You will have to buy something like cables, power supplies or some connectors which depents on the way you install. So I'll say probably the KITS is a good solution. Also, I'll also recommend you to read some INSTALLATION GUIDE to good you some idea of installation. It can be smoother. Hope it's helpful

    llittle advice needed

    What you look for are quite basic. High quality, instant play back, IP67 waterproof and mobile phone viewing. So I think it will depends on how many camera you need and what kind of system (IP? HD? Wireless?) you want.

    Indoor: Turret vs Dome?

    I'll say the housing doesn't really matter, just follow your heart. Nowadays most of the cameras have smart IR & IR cut filter, so it will adjust IR by itself. Even it is indoor use, you will still need IR to see clearly through the dark.
