These are far from hardened security devices - without additional barriers they are very vulnerable, certs or not.
Quod est demonstrandum.

That is what the firewall is for. That has been demonstrated too. I'm not here to get off topic I'm posting to let other people know this is a problem so they don't get stuck with one of these POS.

If you open a hole in the firewall for remote access, the firewall is not there any more.

You should listen to Alastair... The VPN is worthless if you're not using it and instead have punched holes in the firewall...

Another networking wizard. Who said anything about holes in the firewall? No ports are open to WAN other than the VPN. If that were a compromise every large company in the world would be in huge trouble... Forget it I will just delate this account as no one is concerned with factual information on this forum. Keep assuming !

you said it was open to the net...you said nothing about vpn until your last post, and in fact went on about certs....you are a danger to your clientele...we are very concerned about facts..we just dont like liars and dimwits....

I'm having same issue with a 8ch hikvision NVR, I configure it set the client phones with hik-connect, the next day a get a call that the device is offline when they check the app. I have been trying to fix for two weeks, hikvision tech support suggested a hardware issue with the unit, I got a replacement and installed configured everything worked until next day I checked and NVR is offline having same issue.

This may sound a bit crazy but try plugging into a ups. This has helped me with 3 dvr/nvr's that were doing the same thing.

I had the self resetting problem on a DS-7608NI-E2 just last week! The power had failed and was factory reset when turned back on, turns out the small CR1220 battery on the board was completely dead.

HIK VISION DVR DEACTIVATES AFTER REBOOT
HELLO I HAVE A DVR WHEN IT REBOOTS IT DEACTIVATES
IT NEEDS TO BE ACTIVATED ALL THE TIME.
THE DEVICE STAR UP WIZARD IS UNCHECKED BUT STILL ISSUE PERSISTS
THE DVR FIRMWARE WAS UPGRADE BUT STILL IT DEACTIVATES YOU NEED TO ACTIVATE IT

Battery
Various cells and batteries (top-left to bottom-right): two AA, one D, one handheld ham radiobattery, two 9-volt (PP3), two AAA, one C, one camcorder battery, one cordless phone battery
Type Power source
Working principle Electrochemical reactions, Electromotive force
First production 1800s
Electronic symbol
The symbol for a battery in a circuit diagram. It originated as a schematic drawing of the earliest type of battery, a voltaic pile.
An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars.[1] When a battery is supplying electric power, its positive terminal is the cathode and its negative terminal is the anode.[2] The terminal marked negative is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit. It is the movement of those ions within the battery which allows current to flow out of the battery to perform work.[3]Historically the term "battery" specifically referred to a device composed of multiple cells, however the usage has evolved additionally to include devices composed of a single cell.[4]
Primary (single-use or "disposable") batteries are used once and discarded; the electrode materials are irreversibly changed during discharge. Common examples are the alkaline battery used for flashlights and a multitude of portable electronic devices. Secondary (rechargeable) batteries can be discharged and recharged multiple times using an applied electric current; the original composition of the electrodes can be restored by reverse current. Examples include the lead-acid batteries used in vehicles and lithium-ion batteries used for portable electronics such as laptops and smartphones.
Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to small, thin cells used in smartphones, to large lead acid batteries used in cars and trucks, and at the largest extreme, huge battery banks the size of rooms that provide standby or emergency power for telephone exchanges and computer data centers.
According to a 2005 estimate, the worldwide battery industry generates US$48 billion in sales each year,[5] with 6% annual growth.
Batteries have much lower specific energy (energy per unit mass) than common fuels such as gasoline. In automobiles, this is somewhat offset by the higher efficiency of electric motors in producing mechanical work, compared to combustion engines.

I have had the same problem factory reset after reboot and now can't connect the cameras
