RF Exposure Evaluation For FCC ID: VMZGDM610 (page 1-2); IC: 9880A-GDM610 (page 3-4)
Refer user manual this device is a Garage Security Camera, and this device was designed used in
Mobile devices that the minimum distance between human’s body is 20cm. Based on the 47CFR
2.1091, this device belongs to Mobile device. The definition of the category as following:
Mobile Derives:
CFR Title 47 §2.1091(b)
(b) For purposes of this section, a mobile device is defined as a transmitting device designed to be
used in other than fixed locations and to generally be used in such a way that a separation distance
of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and
the body of the user or nearby persons.
FCC KDB 447498 D01 General RF Exposure Guidance v06 Limit
Devices operating in standalone mobile exposure conditions may contain a single transmitter or
multiple transmitters that do not transmit simultaneously. A minimum test separation distance 20 cm
is required between the antenna and radiating structures of the device and nearby persons to apply
mobile device exposure limits. The distance must be fully supported by the operating and installation
configurations of the transmitter and its antenna(s), according to the source-based time-averaged
maximum power requirements of § 2.1091(d)(2). In cases where cable losses or other attenuations
are applied to determine compliance, the most conservative operating configurations and exposure
conditions must be evaluated. The minimum test separation distance required for a device to comply
with mobile exposure conditions must be clearly identified in the installation and operating instructions,
for all installation and exposure conditions, to enable users and installers to comply with RF exposure
requirements. For mobile devices that have the potential to operate in portable device exposure
conditions, similar to the configurations described in § 2.1091(d)(4), a KDB inquiry is required to
determine the SAR test requirements for demonstrating compliance.
When the categorical exclusion provision of § 2.1091(c) applies, the minimum test separation distance
may be estimated, when applicable, by simple calculations according to plane-wave equivalent
conditions, to ensure the transmitter and its antenna(s) can operate in manners that meet or exceed
the estimated distance. The source-based time-averaged maximum radiated power, according to the
maximum antenna gain, must be applied to calculate the field strength and power density required to
establish the minimum test separation distance. When the estimated test separation distance
becomes overly conservative and does not support compliance, MPE measurement or computational
modeling may be used to determine the required minimum separation distance.

Note:
1. The Garage Security Camera work frequency range used is 2400 MHz ~ 2483.5 MHz, the result
close to the limit by the above formula so, we select 2462MHz to calculate the exclusion power
threshold.
