Blink Video Doorbell + 3-Camera Outdoor Security System (3rd Gen) – 1080p HD Video, Two-Way Audio, Alexa Compatible, Black – Monitor Front Door, Backyard & Driveway

I got this video doorbell system to supplement my existing security cams. I already have a relatively robust 4k external security network cams, but the network was missing a reliable front door video doorbell that wasn't solely motion dependent. Now, with this Blink video doorbell that is activated both by motion & physically pressing the doorbell, it will always send an alert & record when someone is at the front door unlike before when it was a hit or miss that was based solely on motion activation. The video quality, HD 1080, is decent for a doorbell but compared to my 4k cams, it's not even close. The difference is huge. The image quality of a 4k cam is so much better, both day & night. The night video quality of the Blink system is so grainy it's almost useless. Good thing I have 4k cams as backups. The two-way audio works well.Installation nightmare...Installation was a fiasco of this relatively easy installation. I made a mockery of the installation primarily due to the fact that there are no written paper instructions. One has to follow the app for the installation that's primarily picture based. The problem for me was I inadvertently used the wrong side of the corner wedge mount. Both front & back of the corner wedge look almost identical if you don't pay close attention. I rushed the installation as darkness was approaching...It wasn't until the next day, when I realized the camera wasn't flushed with the corner wedge. I kept saying, why there aren't any predrilled screw holes on the wedge? Duh, it's because I flipped it & didn't dawn on me until the next morning...a Homer Simpson dumb moment! ?So much easier & faster the second time because I didn't have to apply so much force as previously in order attach the backplate to the corner wedge. This fiasco would have never occurred if there were paper instructions instead of following mainly pictures on the app for the installation. Other apps that use this method do a much better job. For instance, instructions to install the Chamberlain myQ garage system, which I recently installed is app based. It does a better job because the instructions are well written & reinforced with embedded videos. To mitigate this potential issue, I suggest they place a sticker on the wedge that says "this side, front or back only. " This system is wired to my digital door chime, however, I had to upgrade to a compatible transformer (16V, 10 VA) from Home/Depot, which I installed myself.No subscription...I brought the complete kit, which includes the sync module 2 & corner mount. It was on sale on Amazon for under $60.00 & plus free shipping. It's a great deal. I accidentally brought an extra corner wedge mount not realizing it's already included in the kit. I chose the Blink system over Ring because I'm subscription phobic. I just don't like the idea of paying for a questionable service in perpetuity. Blink gives the impression that subscription is required & highly recommended for optimal performance & features when in reality it's not necessary for the most part if you have the sync module2 because it's only has been a couple days since installation & I'm already being bombarded with subscription reminder notifications. Seemingly, Blink purposely sells the hardware very cheap compared to Ring , hoping they will recoup the costs via a subscription revenue stream. It's akin to this old marketing ploy, e.g., the razor & blade; give the consumer the razor for free or at a nominal price & charge a premium for the blades.I like the fact that my doorbell is located on the sidewall instead on the front wall or door, which allows a greater view angle of the outside with the aid of the corner wedge mount. This allows me to see part of my driveway. This wouldn't be possible with a front door/wall mount. The motion sensor reaches far. It goes way beyond 25ft. It was picking up cars that are 50+ ft way. I had to decrease the sensitivity. False alarms appear to be low with this device because most activations thus far have been per real objects. Overall, it's a nifty gizmo that has properly filled a gap in my security system at a reasonable cost. Thus far, I'm content with this purchase despite the initial brief frustration with the installation.
