Security Evaluation

Criterion	Value	Proof	Comment
Known hardware tampering	Rare	🔗 Proof	The camera has an accessible reset hole, USB-C port, Nano SIM slot and microSD slot, creating physical-attack opportunities. No very-common model-specific hardware-tampering history was located.
Known vulnerabilities	Rare	🔗 Proof	Vulnerabilities have been disclosed for other Reolink cameras and Home Hub products, but no exact-model CVE for Go PT Ultra was located in this review. The score is therefore Rare rather than Very common.
Prior attacks	Rare	🔗 Proof	A vulnerability affecting several older Reolink camera models is listed in CISA's Known Exploited Vulnerabilities Catalog. No confirmed exploitation against Go PT Ultra itself was located.
Updatability	Very common	https://support.reolink.com/c/firmware/ 🔗 Proof	Reolink provides a model-specific support section with firmware downloads and upgrade instructions for Go PT Ultra.
Category Score	Score: 2 / 3

Criterion	Value	Proof	Comment
Authentication with other systems	Partial	https://support.reolink.com/articles/12820466682649-How-to-Link-Reolink-Devices-to-Your-Reolink-Account/ 🔗 Proof	Initial setup requires a device password and QR-code or UID pairing. Account linking provides authenticated access, but full mutual authentication for every P2P, cellular and cloud interface is not publicly demonstrated.
Communications	Encrypted with up-to-date encryption	https://support.reolink.com/articles/360004002134-Introduction-to-Reolink-Battery-powered-4G-Cameras/ 🔗 Proof	v
Storage	Encrypted with obselete encryption	https://reolink.com/product/reolink-go-pt-ultra/ 🔗 Proof	The camera supports local microSD and optional cloud storage, but its public documentation does not fully describe at-rest encryption for recordings stored directly on the microSD card. A conservative score is used.
Category Score	Score: 2 / 3

Criterion	Value	Proof	Comment
Account management	Basic	https://support.reolink.com/articles/12820466682649-How-to-Link-Reolink-Devices-to-Your-Reolink-Account/ 🔗 Proof	The owner can manage account-linked devices and share camera access, but the public documentation does not establish full role-based administration for every access method supported by this battery-powered 4G model.
Authentication	Secure	🔗 Proof	Reolink accounts support two-step verification using an authenticator app, email verification and backup codes, in addition to the account password.
Brute-force protection	Basic	🔗 Proof	Two-step verification improves account protection, but exact login-attempt limits or lockout thresholds are not publicly specified for every device and account access path.
Event logging	Partial logging	🔗 Proof	Reolink provides shared-user and online-user information for supported interfaces, along with event playback, but this does not constitute a complete historical authentication-event log.
Passwords	Require change after setup	🔗 Proof	During initial setup, the user scans the camera QR code or enters its UID and then creates a camera login password. A separate Reolink account password can also be used.
