My IP security camera keeps disconnecting from Wi-Fi

Is the camera far from the router or are there a lot of walls in between? The typical issue in these cases is that the Wi-Fi gets weaker and the camera loses connection, so the first thing would be to improve the signal: move the router closer, place the camera in a clearer spot, or consider getting a repeater. Then check that your Hikvision's firmware is up to date, because those disconnection issues sometimes come from there. If it keeps failing anyway, try locking the camera to a specific band (2.4 GHz instead of dual band) in the network settings, because sometimes there are weird incompatibilities with the automatic switching between bands.

IP cameras tend to have connection problems when they're far from the router or when there's interference, but a lot of the time it's due to configuration or outdated firmware. The first thing I'd do is check if your Hikvision has an available update, because manufacturers release patches specifically for these Wi-Fi stability issues. Go into the camera's app or web interface and check it out. In the meantime, try changing your router's Wi-Fi channel (channels 1, 6, and 11 are the most stable at 2.4GHz if you're using that band) because sometimes there's too much interference from other nearby devices.

Another pretty common thing is that the router has power-saving mode enabled or disconnects inactive devices. In your router's settings, look for options like "AP isolation," "client isolation," or power-saving systems and disable them. Also try assigning the camera a static IP instead of DHCP, which prevents the router from losing track of it. On most routers you'd do that from the Hikvision native app or from the web panel by logging in with your credentials.

If none of that works, distance might be the actual problem. A Wi-Fi repeater or access point close to the camera would solve it once and for all. I've seen some Hikvision models just perform poorly at certain distances, so before you spend money on accessories, confirm that the camera is getting a decent signal (check the RSSI level in the network settings, it should be above -70 dBm).

First thing is to check if your camera is too far from the router or if there are obstacles between them, because IP cameras are pretty sensitive to weak signal and disconnect on their own when reception drops. Try moving the router closer, changing its position, or using a 2.4 GHz band instead of 5 GHz if your camera supports it (2.4 has better range). It could also be that the firmware is outdated, so check the Hikvision app to see if there's an update available, and if none of that works, try doing a complete factory reset on the camera and setting it up again, because sometimes the saved data gets corrupted from constant reboots.

Have you checked the camera's event log to see what exactly happens when it disconnects, or does it just disappear from the network without warning?

What people say about distance and walls is basic stuff and you've probably already thought about it, but there's a detail nobody mentions: a lot of Hikvision cameras have a specific problem with power-saving mode. If the camera goes into sleep or standby mode after some time without detecting motion, it disconnects from Wi-Fi to save battery (even if it's powered by cable, some models do it anyway). Check your network settings for anything related to sleep mode, low-power mode, or automatic standby and turn it off.

Another important thing is that the camera's network adapter could be conflicting with your router. Some modern routers have optimizations that disconnect devices that don't "communicate" periodically, or the camera is set to a static IP that suddenly conflicts. Try changing your router's Wi-Fi channel (manually pick a different one instead of leaving it on auto), update the camera's firmware if you haven't already, and if nothing works, consider putting it on a wired connection even if you have to use a long cable. It's more reliable and way less of a headache.
