Here is a link to the article. https://www.cctv101.co.uk/protect-cctv-hikvision-dvr-vulnerabilities-guide/ It was always the same message on everyone's camera.

I remember there was this event late last year where people were hacking into Hikvision and Hikvision OEM cameras and leaving messages on the OSD. Hikvision came out with a firmware update to fix the issue. All that was needed to take the message off was go into the OSD menu and delete the...

From my testing, technically it is able to send a network signal at that range. The issue is the power side. It is not able to send POE power to that distance. So with the PTZ's drawing more power, that is probably the problem at that distance.

You can go with a LTD8308M-ETC. That is the model number that supersedes the model that you currently have. Will support analog cameras up to 2MP native resolution but will do up to 5MP Lite. An upgrade would be the LTD8508M-ST. This model will support up to 8MP so that helps to futureproof...

You can plug an external POE switch to the built in POE switch of the NVR but only one camera will plug and play. The other cameras on the switch will need to be manually added to the recorder. But do know that the built in POE ports on the recorder are 10/100 so there will be a bandwidth...

There are POE switches that have extend mode. For example the Hikvision ones have a switch to turn it on and it will go up to 820 feet depending on the quality of the networking cable and terminations. I believe the Dahua ones will be able to go even farther. Do note that the bandwidth is...

The Hikvision E-Series NVR does support audio. After installing the camera, just go into the settings and make sure it is set to "Video and Audio". By default it is set to "Video". If you want to have audio in the playback then under the recording schedule, there is an "advanced" button on...

There are two ways to do this. 1. The cell carrier can assign an IP address to the sim card. This is usually an added cost. Then you would just put in the IP address, port number, user name and password when adding to the NVR. 2. Make sure camera and NVR are the same manufacturer and is...

You should be able to add it in using ONVIF. So first activate the camera and give it a password, IP address. Then go into your Dahua NVR, select an available port and go into the settings for that port. Make sure to take it off of "plug and play" and put it on "manual". Then put in the IP...

That camera is compatible with that NVR. Note that the aspect ratio for the camera is very different than standard so the decoding may be an issue depending on what other cameras you have on the system. Is the camera not able to "plug and play" or are you just not able to see liveview/playback?

Annke had this special for Halloween. This was the best price I have seen so far. Do note that these have the plastic housings and not the metal ones that Hikvision and other OEM's carry.

This is the Hikvision equivlent for the 6MP PanoVu. Here is the official junction box for that camera. From my testing, it can use the same junction box as the DS-2CD2347GX cameras which is your colorvu turret.

The DVR takes a 12V 2amp power supply which is for powering up the recorder itself and the hard drive inside. The cameras should have their own 12v power supply. Since your DVR is not having any video out I would first measure the voltage of the power supply going to the DVR. It should be a...

Seems like you have a standard I-series NVR and not the Acusense which would be the NXI. I-series does not have any AI processing in it. It will have VCA which is the advanced detections like line crossing or intrusion. If you were wanting the human/vehicle detection or any of the more...

Hikvision's cameras are getting more confusing lately. What use to be cameras labeled as Acusense before meaning they have the AI algorithms to differentiate between human/vehicles. If you look at the new cameras that have come out.... What use to be a basic camera now comes with "Motion...
