Yea, I figured it afterwards. My POS reolink doorbell adapter worked.

You still have to power it via the usual power terminals on the back. It will not power up from the TTL terminals. In fact I specifically said not to connect the +5VDC USB TTL wire to the +3.3VDC pad on the camera due to the voltage difference. You only want to hook up ground and the two...

Thanks for all of the info. That will take me a bit to digest and apply. For the hub, I think it's the only hub that HikVision makes - DS-3E9510P-E.

It would be helpful to know the exact model of this Hikvision POE switch. As an aside this highlights the importance of several things as it relates to hardware, grounding, shielding, and the use of SPD’s. Hardware: Anything that will have to endure the extreme heat, cold, moisture, and...

I believe there are 2 kinds of questions one can ask and the test equipment are different for each. 1) Is the wire continuous? Are there any breaks along the way or is there a break at the terminators? The majority of testers (at least the ones we can afford as diyers) test continuity...

Interesting. The downside to that product is that it requires 2 POE ports at the source. The price on all of these types of products has really plummeted recently. The 1-to-4 POE switch I had in there previously was $68 after coupon when I bought it, and now a comparably-specced item is now...

I’ll add this is also why every commercial, enterprise, and military installation pass through RJ45 connectors aren’t used. Using a dead end connectors provides a measure of protection for the copper wiring. I shoot some dielectric grease into the RJ45 connector before the wire / load bar is...

I think for the benefit of others who may stumble upon this thread and have similar questions and concerns some basics need to be expanded and called out. As it relates to so called thin clients there are three industry recognized types: Thick, Thin, Zero Client. Thick: Is a standard computer...

Thank you sir it helps if you solder the wire then solder the pad lightly then throw down a gob of flux I shake like a whore in church as they say and I've supprised myself with this method. Lots of good info there to go off of for starters. As far as resolution it is mostly limited by camera...

I’ve found when you get “experts” involved it usually costs a lot more. Dont get me wrong, I hired a pro elec contractor to set the service and install the box with an outlet. From there I didn’t need help figuring out what to put in the box or how to wire/configure ethernet or low voltage stuff.

Have you selected Line In vs Mic In on the camera? Make that change through the cameras web interface NOT through the NVR. Ensure you use Internet Explorer to access and to make the change.

Thank you, would a hikvision camera automatically switch to the external microphone if wired properly? I wire it just like your photos, but it still insists to use the onboard crappy microphone. Is there some software setting you must change on the NVR side?

Hey guys do you know how I can fix the above re trigger and trip wire? @wittaj @bigredfish?

I help a small company do alm wiring that has used the DSC legacy systems. The NEO is what they're starting to use. If all else fails call their tech support. My boss was on the phone with tech support on a NEO programming issue the other day. He said the tech support guy said he liked the NEO...

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...
