Anabon field guides · Surveillance Knowledge
Field-tested fixes for cameras, NVRs, PoE and network problems — written for the technician on site, in the order our support team checks them.
The ten items Anabon technical support asks for, how to read the full SKU and firmware from the device, a five-line topology, a precise symptom paragraph, and why requests run through your business account, never the end user.
A field routine for evidence on a CASE NVR: fix the window and clock, find the event with VCA Search, confirm by time, export native plus standard formats, verify, then protect the original with a hash and a log.
When the customer says the app does not connect, work from the recorder outward: online status, P2P registration and device code where used, account and sharing, app and phone network, then the firewall. Eight checks, no open ports.
Milky, glowing or strand-filled night images come from IR bounce, internal fog or webs, not the lens. Here is the diagnosis table, the placement and sealing fixes, and when to spec a turret, white light or PhotonX instead.
A wrong NVR clock produces playback that finds nothing, ONVIF cameras that refuse to log in and exports a lawyer can pick apart. How to set NTP and the time zone, sync every camera to one source, and handle DST.
Two cameras on one address both go unstable. How to recognize the conflict, find the duplicate with device discovery, ARP and the switch, plan a static camera range outside the customer's DHCP pool, and document it.
“No Link” and “Offline” on an NVR channel are different failures: one is cable, PoE or port, the other is address or credentials. The swap test, PoE check and IP check in the order that finds the cause fastest.
How integrators pull a CASE camera into a third-party VMS over RTSP: URL anatomy, which stream records and which one feeds live view, a media-player test, and the AI and search functions that stay with CASE NVRs.
A forgotten admin password on a CASE camera or NVR is recovered through the official path for that model and firmware, with ownership verified. What to prepare, and the handover policy that prevents the next lockout.
What each NVR hard drive error means, how to run a SMART check, when a reformat is enough and when the drive must go, the printed per-drive capacities on CASE NVRs, and the back-to-back warranty rule.
