It utilizes specialized Topstock lenses installed along elevated racks to continuously monitor items stored above the aisles. Powered by advanced computer vision, these lenses detect product presence, identify misplaced inventory, and flag low stock conditions in Topstock, an area that has traditionally lacked visibility and often contributes to hidden out-of-stock scenarios. By digitizing this overhead inventory layer, Topstock Rail enables retailers to proactively surface available stock and trigger timely replenishment. Complementing this capability, the center lens focuses on the customer- facing shelves, capturing real-time insights into on-shelf availability, facings, and gaps. Together, the Topstock and center lenses provide a unified, end to end view of on the sales floor. This integrated system enhances replenishment efficiency, reduces out-of- stock incidents, and improves store operations by delivering precise, actionable insights to associates, ensuring products are always available where customers expect them 3VUSION -Topstock Rail User Guide TECHNICAL DETAILS TopStock Charging: Resolution: Motorized Lens: Motion Sensor: In-camera GDPR protection: Dimensions: CPU: RAM: Internal Flash: LED: Networking: Active NFC: Bluetooth: BLEStandard: WIFI: Wireless firmware update: Operating Temperature: Compliance: Packaging Unit: Weight: No 108 MP Yes Yes Yes 1205 x 52 x 48 mm ARM 32 Bit SOC 128MB 32MB RGB LED AC 2.4/5GHZ WIFI No 2.4GHz 5.4 2.4 GHz / 5 GHz (WIFI 5 PSK) 2412~2462/5250~5350/5470~5725/5725~5850MHz Yes 10 °C -40 °C CE, RoHS, FCC/IC 4 rails / box 2796 g with batteries 4VUSION -Topstock Rail User Guide IMPROPER USE •Never open or disassemble the electronic device, only the battery may be replaced by trained users. •Do not use the electronic device if it is defective. •Unauthorized changes or modifications to the electronic device and their components without the consent of VusionGroup are not allowed. •Do not use the electronic device with spare parts and accessories which are not tested and approved by VusionGroup. •NEW AND USED BATTERIES CAN BE HAZARDOUS, KEEP THEM OUT OF REACH OF CHILDREN Swallowing or placing batteries inside any part of the body may lead to severe or fatal injuries within 2 hours, due to chemical burns and potential perforation of the Esophagus.

Product Name/Model:TopStock Gen2.0/ TSR2-0120-A FCC ID:2ACQM-TSR2-0120-A ReferenceFCC KDB 447498 D04 v01 FCC RF Exposure Where the Device Under Test (DUT) can be shown to meet the requirements for an exemption pursuant to FCC 47 CFR §1.1307(b)(3), an evaluation is not required with respect to the limits on human exposure to RF emissions provided in FCC 47 CFR §1.1310. 1.Determination of Exemption As per 47 CFR §1.1307(b)(3), for single RF sources (i.e., any single fixed RF source, mobile device, or portable device), a single RF source is exempt if: A.1-mW Test Exemption: The available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption may not be used in conjunction with other exemption criteria other than those in paragraph (b)(3)(ii)(A) of this section. Medical implant devices may only use this exemption and that in paragraph (b)(3)(ii)(A); B.SAR-Based Exemption: The available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold P th (mW) described in the following formula. This method shall only be used at separation distances (cm) from 0.5 centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive). P th is given by: ( ) = ( 20 ⁄ ) ≤20 20 < ≤40 Where = − 60 And ( ) = 2040 0.3 ≤ <1.5 3060 1.5 ≤ ≤6 d = the minimum separation distance (cm) in any direction from any part of the device antenna(s) or radiating structure(s) to the body of the device user.

Page 2 of 4 C.MPE-Based Exemption: Using Table 1 and the minimum separation distance (R in meters) from the body of a nearby person for the frequency (f in MHz) at which the source operates, the ERP (watts) is no more than the calculated value prescribed for that frequency. For the exemption in Table 1 to apply, R must be at least λ/2π, where λ is the free-space operating wavelength in meters. If the ERP of a single RF source is not easily obtained, then the available maximum time- averaged power may be used in lieu of ERP if the physical dimensions of the radiating structure(s) do not exceed the electrical length of λ/4 or if the antenna gain is less than that of a half-wave dipole (1.64 linear value).

The EUT contains 2400 – 2483.5 MHz DTS (WIFI and BLE) transmitters, UNII-1, UNII-2A, UNII-2C, and UNII-3 WLAN transmitters. ERP exemption threshold was calculated using the lowest operating frequency for each transmitter; the lower frequency resulted in a lower exemption limit.

And each transmitter operates below its applicable Threshold ERP Limit; thus, the RF Exposure Exemption requirement is met. According to 47 CFR §1.1307(b)(3)(i)(B), this device complies with the RF exposure test exemption.

Page 4 of 4 2.3Simultaneous Transmission Evaluation The transmitters on the EUT are located on different SoCs. The 2.4 GHz and 5 GHz WLANs are on one SoC (SoC1) and share the same antenna; the BLE is located on the second SoC (SoC2) and has its own antenna. SoC1 could only either transmit 2.4 GHz or 5 GHz WLAN. Thus, the worst-case RF exposure is a combination of the highest ERP from each SoC. The highest ERP from SoC1 is 0.065 W and from SoC2 is 0.006 W. Per 47 CFR Section 1307(b)(3)(ii)(B), the DUT qualify for simultaneous exemption if the transmitters meet the following requirement: 0.065 0.768 + 0.006 0.768 = 0.09 < 1 The DUT qualifi…
