Reliably and adequately, it can't. To achieve decent battery life, the cams offer no pre-trigger buffer (to see what occurred a few seconds before a motion trigger), no 24/7 recording, poor motion detection, weak and undependable wireless operation and low IR output at night. Take one of the...

As I acknowledged right before your post.:cool:

We asked Jeremy Hewitt, senior systems engineer for Inrush Broadcast Services, for his thoughts on facility grounding. He recommends the Ufer ground for new facilities. “A Ufer ground typically consists of steel reinforcing rod (rebar) directly embedded in concrete. It must be at least 20 feet...

I agree it's likely what it's supposed to be, a Ufer ground, but it's not embedded in the concrete as is typical. Instead it may be connected underground as you say to a grid of interconnected ground rods. That said, if I was doing my best to install the best grounding system I could achieve I...

If one looks closely, that copper wire comes in from the top right and continues on the backside of the rebar into the ground. Who knows what is buried under all of that. There could be of a radial system of copper wires fanned under the earth.

It should be noted even fibre cable that is armoured can result in the same problems. Especially if the cable is coiled and placed on a server cabinet. The induced voltage (EMF) can easily rise to 20 - 50 KVA! Other things to consider is incorporating toroidal ferrite cores on the cables...

Good advice on grounding, etc. Additionally, the OP should know that the lightning does not need to STRIKE. If the slack in an ethernet cable is looped neatly for storage, that loop of wire can generate current when the emp from lightning hits it. I lost at least 2 cameras most likely from...

People / cars should not normally be coming within 10 feet or so of your entrance gate. I’m presuming authorized cars stop at a key pad or something and wait while the gate opens. So if your camera allows a trip wire zone between the normal place cars stop and the gate, you should be able to...

Hey gang. I've got a DAHUA DH-SD59225U-HNI and a clone. Tornado season occurred, and with the pouring rain, I learned I did not have a good seal on the mounting box and did not drill a drain hole in the bottom. The ethernet connections got wet. Both cameras are none functional. One accepts...

Sorry I forgot to share this screenshot

Thanks alot guys. The different browser worked. However when I changed the alarm schedule it stopped the alarm going off but outside of the hours I've set but it also turned the trip wire off also all together. Before now, we had trip wire active during the day with no alarm, but the alarm...

Hello everyone, New here, just getting in to the world of IP cameras and have already learned so much following this community, so thank you! I'm not sure if this post should live here or somewhere else but figured I would start here. I have an EmpireTech IPC-Color4K-T flashed with the latest...

My bricked RCA DB is not powering up off the USB TTL adapter. So have no idea how yours powered up. I'll just throw it in a garbage lol Still have a battery coming for my working Hikvision DB, maybe that will work..

Yes sir from what I have seen, I should be able to slide the bar in there. My issue was running the wire. For example on my house I was able to take the soffit off and run the wire behind via the channel/groove and replace the soffit. Guess I’m looking for a safe way to get the wire behind the...

I’m going to give my two cents worth of knowledge and best practices / trouble shooting. As lots of good information has already been provided but wanted to stress a few key points for the benefit of others who may ask the same. Wire: The cable must be solid copper and 23 AWG. So rated for...

Has the one cam always done that? if so, proceed: In warranty? Return it. Out of warranty? Open 'er up and compare color codes on the wire harness running from the PC boards to the pan motor/mechanism with one of the 3 cams that works correctly....maybe a pair got put in the wrong position...

Keep this simple, as anyone who is involved in so called (IT) would use the most common tools and solutions to identify or isolate the root cause. As you stated you have no clue where the problem lies yet nothing I’ve read shows any basic network troubleshooting?!? Ping: Run a continuous ping...

We could always send 120volts to a wire at the bottom of the doorbell when they try to stick a paperclip up there ;) If we need to pull the DB we just turn Off power...

I reside in a residential building equipped with a 30-line analog voice intercom system. Additionally, I have a Dahua KTP02 Video Intercom Kit (VTO + VTH) installed at the garden door. I'm exploring the possibility of connecting a wire from the intercom headset to the Alarm IN port on the VTH...

A few things come to mind. Most Smart Doorbells have internal batteries. How long will they last? Who knows, I ran my LaView DB for 3 1/2 years. Not saying that is your problem but worth checking into. Next, I know this will not sound right since it has been working for 2 years BUT, I would...

I'm trying to troubleshoot an odd issue that I am seeing with my Amcrest AD410 doorbell. I've had it connected to my doorbell wiring for the past 2 years without issue, and then all of a sudden in the last week it started acting up and would die about every 24 hours. It would show completely...

Thanks! That's great info. Yes, please post video when you do this!

The vibratory plow "puller" is basically a knife blade with a sling attached for holding pipe or wire. Lower blade into ground, vibrate the blade, and drive slow. Pipe gets dragged underground behind the blade. Damage to ground is really dependent on soil conditions and pulling depth. Roots are...

I have been using TP-Link Pharos system for the last 3 years linking house to a shed 300 feet away and also installed the same between commercial offices and a Pavilion 500 feet away. - CPE510 system is ultra reliable and very reasonably priced. Stated range up to 13KM away so a few hundred feet...

When I turn them back on, it starts working, also, it always just shows, ONVIF movement, is that what the trip wire does? I was hoping it could also show the is a person.

I'd wire a tamper-switch /door-open switch on that cabinet or closet to a "Shelly-1 UL" input and have it tell Blue Iris to send you a Pushover alert "DOOR OPEN". https://ipcamtalk.com/threads/alarm-output-nc-or-no-via-wired-connection-into-camera-to-trigger-bi-alerts.58124/...

I did some rough calculations based on my 4.8-120mm PTZ zoom range, to estimate what I would need. Dahua work on a 0-25 zoom range for that 120mm PTZ 25% = 30mm 50% = 60mm 75% = 90mm 100% = 120mm Works out at roughly 4.6mm over estimate per zoom increment in theory. Which equates to zoom 7...

You got it. And I would think it easier to move the PLA in the garage around to find the same 120VAC leg that the house PLA is connected to.

Actually 4 wires, neutral and ground. There are 2 hot wires from the street transformer to the house and since I have a double pole breaker leading to the garage both legs are present. So what I think you're saying is I just need to find the common hot wire from the transformer that both the...

No. What I'm saying is plenty of trunk slamming alarm installers don't want to bother stocking / using heavier wire when necessary. Sometimes people may run 22-4 to a simple contact sensor, but they only use two wires. The other two would be spares in the unlikely event the cable is partially...
