Frequently Asked Questions

Yes, all models have a built-in microphone and support synchronized audio recording.

RV Twinview Wireless / RV Ranger PRO Wireless: 4GB-C128GB; RV Oracle Ultra PTZ: up to 512GB (EXT3/EXT4 file system); RV FourSight 4G NVR: up to 256GB (supports FAT32 / exFAT); RV Oracle Ultra PTZ: supports Micro SD card (512G) local storage, up to 512G, supports pan-tilt RV Oracle Ultra Bullet: supports TF card recording, up to 512G, with an RS485 recorder interface. We recommend genuine Class 10 or higher cards from well-known brands (such as SanDisk or Samsung); low-quality cards may show a correct capacity but fail to record or loop-overwrite.

No. Recording requires a storage medium: a microSD card (local, free) or cloud storage (paid subscription) — at least one. Without a card or subscription, you can still view live and receive detection alerts, but recordings cannot be saved or played back.

On first activation, you can claim a free 1-month cloud storage trial; after the trial, a paid subscription is required. Subscription tiers and prices are subject to the actual pages in the app.

No, they are two separate services: the 4G data plan is the “connectivity fee” that keeps the camera online (required for 4G models; includes a 7-day free unlimited trial); cloud storage is the “storage fee” for saving footage to the cloud (optional; includes a 1-month free trial). If you use microSD local storage only, you can use the camera normally without cloud storage.

No. When the card is full, it automatically loops and overwrites the oldest footage; no manual cleanup is needed. Please download and save important recordings promptly (you can download them to your phone in the app).

In the app’s playback screen, select the clip to download to your phone’s album. The IB-series NVRs support USB backup and MP4 export.

Network outage: local microSD recording is unaffected and continues normally; you can view remotely once the connection is restored. Power outage: plug-in models (RV Oracle Ultra PTZ / RV Oracle Ultra Bullet / RV Vault NVR) stop working; battery models (RV Twinview Wireless / RV Ranger PRO Wireless / RV FourSight 4G NVR) are unaffected. The RV Vault NVR series supports ANR (Automatic Network Replenishment) — footage is cached locally during a network interruption and automatically backfilled once the connection recovers.

MicroSD: one-time purchase, no monthly fee; but footage can be lost if the device is stolen or damaged. Cloud storage: monthly/annual fee; footage is in the cloud, so it survives device damage, and it supports remote access. We recommend adding cloud storage for critical spots (entry doors, warehouses) and using microSD for ordinary locations. You can also enable both for double protection.

You can format with one tap in the app’s device storage settings (formatting erases all footage on the card, so back up important clips first). We recommend formatting every 3-C6 months to maintain read/write performance; you can also try formatting first when recording anomalies occur.
