    Discussion about Hikvision

    Y You could well be right. Despite that it's spec'd for 5MP cameras and 20Mbps inbound bandwidth, maybe the aggregate bitrate that's configured is too much. @crist121 - maybe re-test the Annke camera with one or more of the Chinese ONVIF cameras disconnected.

    Discussion about Hikvision

    Sure. But @crist121 has already tried the Hikvision protocol and it's not working properly. It's an old NVR - with very old firmware - an increased chance of a compatibility problem. Which is why ONVIF as a fallback is worth trying. There are quite a few models in the Annke I51xx range, with...

    Discussion about Hikvision

    I've not seen that specific model - but if its like similar models you need to Enable ONVIF, and add an ONVIF user. This from an Annke I51DF -

    Hikvision NVR DS-7104/08-SN/N/P, DS-7804/08N-SN firmware

    I believe that is a Chinese model - is that correct? Applying EN/ML firmware to a Chinese NVR will most likely stop it working. Je crois que c’est un modèle chinois - est-ce exact? L’application d’un micrologiciel EN/ML à un NVR chinois l’empêchera très probablement de fonctionner.

    Alternative way of recovering HikVision NVR password

    Unfortunately, that password reset request file can only be processed by a Hikvision support person on one of their private systems. What cameras do you have connected to the NVR, and what version of firmware are they running? If the firmware is 5.4.0 or older - the camera configuration file...

    ADD PoE Ports With External PoE Switch

    Yes, that's normal. One or more, or even all, of the NVR PoE channels can be reconfigured to connect instead to cameras on the same network segment as the NVR LAN interface, if its something that's needed by the network wiring topology. But it still doesn't allow more cameras to be connected...

    ADD PoE Ports With External PoE Switch

    No - it's a 4-channel NVR, that's the maximum number of cameras it will allow to be connected.

    Admin password recovery - Hikvision NVR DS-7204HQHI-F1

    Try them again - or another country Hikvision support. Although they generally don't respond to end-users, it can vary with whichever person handles the request. You might get lucky. Remember to not power down the device after exporting the reset request file. Next steps would be to use the...

    How to - Fix your 15-beep-bootloop Hikvision DS-76xxN-Ex NVR, or convert to EN and make it updatable

    Hmm.. that's certainly odd, you are right. Just quietly doing nothing. Not a behaviour I've previously seen.

    How to - Fix your 15-beep-bootloop Hikvision DS-76xxN-Ex NVR, or convert to EN and make it updatable

    Dumb question, for which apologies : Did you select and enable the flash chip with 'sf probe 0' ?

    ColorVu 1/1.8"

    I agree, if you look closely at the 1/1000 second exposure images, the DS-2CD2087G2-L is marginally better, though it has a 6mm lens against the 4mm of the other 2 in that comparison. But a worthwhile advantage is the 8MP resolution, allowing more digital zoom.

    How to - Fix your 15-beep-bootloop Hikvision DS-76xxN-Ex NVR, or convert to EN and make it updatable

    In what way is it useless? If it still exists - it should be able to read and write mtdblock1 where the bootpara data is held at least on the k41 NVRs. That's not a model I've ever looked at, I don't know where that would be held.

    Firmware for Laview NVR LV-N9808C8E?

    Outbound, presumably? Be aware that this will also disable time sync if you are using an internet based time server, and also email alerts if this is something that you have configured and rely upon. Also - check if your router has UPnP enabled, and if so, disable it. Many do, by default. If...
