I went ahead and purchased the doorbell from Nelly's. Here are my thoughts, a bit random but hopefully complete.
Installation, please see posted pics. Since the wires to my doorbell are lamp/appliance wiring (18 gauge stranded copper with thick insulation, like a lamp cord) and protrude straight out of the mortar there was no way to flush mount the doorbell to the brick and make the connections. So I purchased a Decora switch wall plate that give you about 3/8" clearance from the brick to the doorbell. I drilled a couple of holes in the plate for the doorbell and JB welded in a couple of nuts so I could mount the doorbell after the plate was secured to the brick. No exposed screws this way. I placed weather stripping on the back of the plate (top and sides) to prevent water intrusion and used the doorbell's gasket to the plate. To connect the wires I used the doorbell's included connector but cut it in two to lay flat on the brick. I think the install went well. Very easy to link the Guardian Vision app to the doorbell.
The doorbell would really benefit from a camera axis adjustment. See the pics. Really wish I could aim it towards the entrance. Another thought would be to offer a wedge gasket of say 15 degrees so one could mount it facing left or right. A simple plastic part to include with the doorbell and would be very helpful. The IR reflection makes night time viewing horrendous. Also, you cannot disable the doorbell's IR which I really would like to as there's an outdoor IP camera a few feet above the doorbell that has plenty of IR.
My setup uses a 16VAC 10VA transformer and a mechanical chime. The chime used to ding-dong but now only dings. However, I had to disable the chime altogether. The plunger that sits in the coil on a spring would dance around in the chime often rattling loudly. It does this because the doorbell is always pulling power at various current levels so the chime's coil is energized and the plunger vibrates. So I secured the plunger in place, no more ding or dong. This possibly could be rectified with another model of chime but my guess is that any chime will have "slop" in the plunger to coil hole as they don't want them to stick and don't expect them to be energized except momentarily when the bell is rung.
Does it work? Kind of. The Guarding Vision app usually connects but sometimes says "network unstable" and won't connect. A couple more tries and it works. They WiFi strength at the doorbell is high and I get over 20Mbps down and 10Mbps up at that location on my iPhone. I tried a different router's WiFi only 20 feet away from the doorbell, same result, so I'm certain the issue isn't WiFi strength. For that matter there is a HikVision and a Foscam WiFi camera within a few feet from the doorbell that never ever has any issues. Firmware version of the doorbell is 1.4.62 build 171201. I'm hoping future FW versions will help. Also, some doorbell presses don't alert the app. The doorbell chimes but no phone alert. A bit disappointing.
The web interface to the doorbell is typical HikVision but missing many features. There's no playback function and you cannot view or change the IP address. You can change the IP address via SADP but then you cannot link the doorbell to the Guardian app. Not really too big an issue unless you want to assign the doorbell an IP address, which in my case I would as I like to have my cameras and NVR on an upper range of IP addresses. I can live with this. The fonts used to display time and date are not modifiable and I believe they really are too small when viewed on a smartphone. There's a feature called "Power Booster" but I have no idea what that does. It is off by default.
The doorbell easily connects to my HikVision NVR (DS-7616NI-E2) in HV mode. In the GV app I turned off motion detection alerts but this also disables motion alerts to the NVR. Very disappointing, ideally I would like my phone to be alerted only upon a doorbell press but the NVR to record anytime there's a motion trigger. I cannot make this happen. Also, in this mode the doorbell only records to its SD card upon doorbell presses, no motion recording. I think FW could fix this and really needs to happen.
With my phone set to vibrate only, the GV app still rings the phone rather than only vibrate it. This will be a big issue in many settings where you do NOT want your phone to make noise. Contempt of court anyone? I hope this can be fixed.
Voice quality. Although I've turned up the volume and microphone sensitivity both to max, the doorbell's volume is rather low as is it's pickup of sounds relayed to the phone. Compared to my friend's Ring Pro its volume is too low.
In a nutshell:
- must improve WiFi stability!
- must be able to disable IR
- must allow for motion triggered recording to SD and NVR without alerting the GV app
- really need chime extenders. Why even keep the old mechanical chime unit given the problems it can create? Have the doorbell signal WiFi enabled AC plug-in chime units that you can place all around the house/garage (anywhere that has good WiFi strength) and you've solved another homeowner issue where you can't here the doorbell in some rooms or if the TV/stereo is on.
- must include an off axis gasket/shim and/or mounting plate to aim camera
- really need to improve on voice volume level and microphone sensitivity
- would be nice to be able to change the IP of the doorbell and have the GV app follow along (change the IP from within the GV app would be nice)
- would be nice for the doorbell to report its WiFi strength and incoming voltage to ensure neither are a problem
- my phone's battery is depleting faster than usual and it reports the GV's background app is to blame. This could be a showstopper. Need to fix this if possible. I need to spend more time with the doorbell but if this is the case then the doorbell gets thrown in my pile of obsolete electronics, along with my cash and efforts.
Well that's it for now.
