I had read user feedback that there are issues with motion detection alerts being slow, although this could be with the HikVision app. Also choppy WiFi. Possibly can be resolved with a firmware upgrade. Any experience of this?
I don't use the hikvision app with the DB2, so I'm afraid I can't say.I had read user feedback that there are issues with motion detection alerts being slow, although this could be with the HikVision app. Also choppy WiFi. Possibly can be resolved with a firmware upgrade. Any experience of this?
I retested this myself again today with the latest firmware. Unfortunately, the results are inconclusive. I cut a tiny piece of tape to completely cover the lens to ensure software motion detection was disabled and verify the onboard PIR was working. It worked... sort of (inconsistently is the way I would describe it). Conducting walk tests with the lens covered, it triggered motion, but only 4/10 times. Uncovering the lens again, I was able to trigger the camera 10/10 times. This indicates SOMETHING is there, but it doesn't seem very accurate.According to your table the EZVIZ DB1 "spec sheet claims to have PIR, but doesn't seem to be true." Are you sure about that? It does appear to have a PIR-like window inbetween the camera and the button. The YooSee spec sheet used to claim it had a PIR but not anymore.
Thx!Good question.
These doorbell style models are meant to be used as easy replacements to existing doorbells. The manufacturers take some basic steps to secure the doorbell to the wall, but it's not going to stop someone really determined - if you've seen a Ring doorbell in person, these devices are about the same as far as security goes. The cases have torx screws to prevent people from opening them up, and some of them are reinforced with basic brass threads. Ultimately though, they're still secured with fairly soft plastic, so even a forceful kick could knock the doorbell off the mount. It's not that hard. Of the two I have seen in person, I would say the Dahua is a little more secure compared to the Hikvision (the two tiny torx security screws can be defeated with a determined screwdriver), but not by much.
Keep in mind neither of these two doorbells support POE. Only the yousee model has an ethernet port, and even then it's only a data port. To power it, you would run either AC/DC power or use their included POE splitter. If you use the splitter, your install location needs to be large enough to fit the splitter in the wall.
If you're streaming video to a BI server none of the models listed above require an SD card. The SD card is only necessary if you want to use the doorbell's app to view events.
Everyone's environments are really different. If you're in a dense urban environment, you may want to look into a doorstation style setup which is designed to be integrated into the wall and installed more securely. These aren't simple doorbell replacements, but more like intercom systems.
Otherwise, your idea to flush mount the device might work.
So i got the second doorbell, ive set it up in my bedroom to test it out, so far its doing pretty good, electric chime always sounds, video is good, slight problem with two way sound on feedback (have to mute the mic or speaker to stop the feedback loop) , pir sensor works well, phone app always receives a notification although sometimes its a loud call on the phone and sometimes its just a small notification like an email sound. Havent figured out how to display the video on my google nest hub.I didn't include the skybell since it doesn't appear to support RTSP
The second doorbell received poor reviews in the past and has been superseded by the SD-M5. There is an existing thread here on it. The RFID capability is cool, but I'm not sure how it would be integrated.
I did not include intercom systems since they're usually proprietary, but yes, they could work for some people.
Please allow me to add a correction. The port on the Yoosee is poe and data---it works with a single cat 5/6 poe cable plugged into the back of the doorbell from your source. While there is a splitter included in the camera package (as well as a separate power cable that could alternately be used in another port on the back of the camera) none of those need to be used. I have it hooked up at the end of about a 100 ft run with just the ethernet cable plugged in to the back of the doorbell. The original question was what voltage on the poe was correct and if an at/af (48v) device would fry the doorbell since it was not rated at/af compliant. I actually wired it up to two different injectors directly before installing it and it worked, however for safety, I did use a stepdown convertor from ubquity that provides 24v before ultimately hooking it up to the at-poe-switch. But note that the adaptor is located at the switch end of the run. The only connection required at the doorbell end is a single cat 5/6 cable.Good question.

It's not a splitter, it's a passive PoE injector and goes on the other end of the cable, right after the switch:Oh, no kidding. I thought the port on the doorbell was data only. That's great news. I'll update the chart in the first post.
What's the included splitter used for then?
Thanks for the trick on using the Bosch relay to interface to HA. Interesting that the DB11 actually has a couple of small batteries in it that allows it to continue operating even though the supply voltage gets yanked to almost zero!Seems like every other day there is someone asking about the best Blue Iris compatible doorbell for the residential market. I'm writing this thread to share my findings so far comparing the current options. This is a continuation from my post on the DB11 here. Many new doorbell cams were announced at CES this year in January, but most have not hit the market yet or are still incompatible with ONVIF.
(Doorbird is also a viable option since it checks most of the boxes, but I did not include it here as the resolution is low and price point is too high compared to these models).
I'm embedding a few sample videos comparing the hikvision and dahua cams. Both videos are mounted from the same exact location.

SUMMARY OF FEATURES & KNOWN ISSUES
Following is a comparison chart based on information and feedback from everyone here. Thanks to all the people who posted information! (I do not own the yousee model, so I've not had a chance to test it). I will try to update with known issues as they are reported or as I find them.
ADVANCED FUNCTIONS/HACKS
Integrating doorbell button notifications to home automation systems
APIs have not been found yet to read events, so some users have suggested creative ways to send doorbell button press events to other home automation systems. In my case, I'm using a simple relay wired in parallel to the power wires. When the button is pressed, voltage drop causes the relay to be tripped and you can send a simple on/off signal to any custom switch (alarm sensor, zwave switch, etc).
My doorbell install uses DC 12V, so a standard automotive 12V relay such as this one works well, but the concept should be similar for AC powered installs.
Use ONVIF to send PIR events to BlueIris
(Why does this matter? PIR is usually a reliable way of detecting motion, sometimes more accurate than software. In some cases, it may be better to trigger alerts based on the camera's onboard motion detection and send this alert to BI in order to lower false positives)
If you want the doorbell PIR to trigger blueiris, take the following steps in BI. First verify your camera is capable of sending ONVIF streams (not just RTSP). In camera configuration in BI:
- Instructions for Hikvision models
- Set Discovery/ONVIF port to 80
- Set path to /Streaming/Channels/1?transportmode=unicast&profile=Profile_1
- "Get events with PullPointSubscription" must be checked
- In the camera, go to PTZ/Control tab. Enable PTZ, select Hikvision from the Network IP dropdown.

This is a more complex subject involving many moving pieces, so I will add this later
