Hello everyone I’m new to the forums and new to ip camera. I have a Hiseeu DVR with 5 camers hooked up, they all worked fine for roughly a year until last month they all stared going on and off line. I’m not sure where to start troubleshooting. any Help is appreciated

Is it during day and night or just night?

In most instances it ends up being a power issue or corrosion issue on the wires. Did you use dielectric grease on the connections outside?

Troubleshooting would be to unplug all but one camera and see if it still happens. If it stops happening, then it is an issue with the power. If it does continue, then supply power another way and confirm if it is the power supply.

If it is still happening after that, then bring a camera in and try with a short premade known working good quality cable and test it that way.

Please confirm these are IP cams on CAT-5 cable, not analog cams on siamese (coax video+ 12VDC) to BNC connectors.

Wireless is very problematic for surveillance cams in that the data stream is constant and is not buffered; if any errors occur because of interference or lack of bandwidth the devices will attempt to re-establish communication and this causes drop-outs, jittery images, etc. Wireless is not recommended for CCTV because of this unreliability.

IMO, the only way to achieve some acceptable performance from wireless cams is to have a dedicated, high output / high sensitivity wireless access point that is for a very limited number of cams and nothing else. Those cams should be set for nominal resolution and frame rate, as low as acceptable.

Oh, yeah wireless is a whole other animal. A neighbors microwave can interfere with it, a car driving by with wifi hotspot, etc. Maybe a 5G tower went up close by. That is probably the problem.
