A while back when the Wyze Window Mount first came out, there was some discussion about the supplied adhesive for the window mount being up to the job. One poster said his Wyze Window Mount adhesive failed and the v3 fell from the window. The industrial type adhesive used has some strict application requirements, that if not followed, will yield a less than optimal installation.
Removing the magnetic base from the camera will reduce its weight and result in less prying force on the Wyze mount’s adhesive. The camera’s cantilevered attachment to the window mount results in uneven loading of the mount’s adhesive. Most of the tensile forces occur in the upper part of the adhesive tape, the lower part of the tape sees compression force. All of the tape reacts to the downward sliding force due to the camera’s weight.
To provide additional support, I designed two tethered (string) anchor systems, that each use a filler plate/string keeper. To further reduce the force on the camera from the cord weight, a cord anchor is also used. Links for the tether anchor, filler plate/string keeper, and cord anchor are given in this post, at no charge. Of course, to get a good tether anchorage for the camera, good tape such as Scotch two-sided mounting tape, 3M VHB Mounting Tape, or equivalent should be used in accordance with their instructions.
The filler plate/string keeper is pretty much self-explanatory per the pictures. There are two versions of the plate/string keepers, the string yoke and the string eye.
The tether anchor needs some explanation for the three hook-holes. A review of adhesive wall anchors on the market shows that in general the hook part of the wall anchor is located at its bottom. The expected loads for the anchors are from hanging items. The loads are mostly vertical with little force outward from the wall. In the case of forces applied to the wall anchor at a 0° to -45° angle, the middle hook-hole of tether anchor needs to be used. At a -46° to -72° force, the intermediate hook-hole should be used. If the force engaging the wall anchor is -73 to -90°, the bottom hook-hole should be used. For tether string angles between 87° to 90° any hole is fine. As for how one is to determine these angles, eyeball them the TETHER ANCHOR info sheet. The information sheet and picture provide follow-up on the above explanation.
The cord anchor is pretty much explained by the picture. There are two styles, one for the flat ribbon cord that comes with the v3 camera and one for a round 3mm diameter cord that is found on longer cords.

The next two pictures show trial setups on the countertop before committing to an actual window installation.
The next picture is an actual window installation of the string yoke system.

Below is a picture of the String Eye Tether.
The next two pictures show a Wyze Window Mount fitted with a 20° aiming wedge and tethered with a string yoke vers tethered with a string eye.
After working with the string yoke and the string eye versions of the tethers. I prefer the latter. In my opinion, the string eye is a more compact design and pleasing to the eye (as much as something like this can be pleasing).
The tether anchors and cord anchors can be used in other non-camera applications.
