Remote location CCTV needed

[DROP_TABLES]

Hi, we have a remote location that we need to set up some CCTV at. The threat level is medium-high, with concerns over arson. We need some form of system installed within a week. Total budget would around £2,000 for a 4 camera setup that can expand to 8.

It has no IT infrastructure currently, no internet connection and no mains power. There is a generator on site but it's only run when needed, and we have some deep cycle leisure batteries. We'll need to use a 3G/4G modem for remote access, and we'll need a 8 port POE switch that's happy running off batteries (which is preferred, 12/24/48v?) and 4-8x POE IP CCTV cameras. I've installed plenty of IP cameras and network switches, and my day job is IT systems administration. Just the complications here are going to be having a network that's entirely able to run off batteries, so everything needs to be bought with low power requirements in mind.

The site has 4 'buildings' if you call them that, 3 beside each other and another 30 metres away.

I think the most difficult part is going to be the NVR, we'll need something that can record on site, happy with running on batteries so a DC power supply is a must to eliminate AC conversion losses. And another spanner in the works, if the entire site is torched, we still need the footage. So it needs to be backed up as close to real time as possible off site over the 3G/4G modem.

A nice to have would be two NVRs, in different locations, both recording locally, with one sending a backup off site. So if the location that NVR1 was in was damaged, NVR2 still has all the footage. Obviously this doubles the total power requirements needed for NVRs. It would be ideal if the cameras could do edge storage as well as having the NVR - although this is a nice to have and not a requirement.

We'll need to run CAT5e everywhere for the cameras (I know I'd prefer CAT6A but this needs done in haste).

I know the simple solution is to just have someone stay on site and keep a look out, but that's not sustainable for the foreseeable future.

Any recommendations for NVRs, cameras, switch and cellular modem? Many Thanks.

Welcome to the forums, is a thread to check out. Good Luck!

Security cameras on Construction site

Iv been asked to install security cameras on a number of construction sites for a company, the particular sites are just at the ground works stages so there is no power available to the work progresses. Solar seems to be the obvious choice of power but I have no experience of this, I was...

Here is another interesting thread. Not much information but you could contact the poster and ask him questions on how it came out.

Dahua Nvr- cell to internet - remote access options

Hello all. Getting close to completing my testing of a remote all solar powered security system. Learned most everything from scratch reading 100's of post on these forums (ie, dahua starlight, ubiquity, solar, battery, etc) Originally was building a BI system, but decided on a small Dahua NVR...

Hi

Standard PoE runs at 48-56 volts. NVRs, I'm not sure, but probably 12 volts. Cameras typically take 12 volt input as an option too via their DC barrel connectors, so if you use passive PoE adapters instead of active PoE switches then you don't need to create a 48v battery system and can likely do everything with 12v.

As for making footage survive a fire, that will be tricky. I don't know if NVRs tend to offer any kind of realtime offsite backup capability. I know it can be done with Blue Iris on a PC, but you need to keep the clip durations very short because the FTP backup operation doesn't begin until a clip file is closed. You might consider putting the NVR in a hidden fireproof enclosure. Just spitballing here, but maybe in a plastic barrel buried underground, with only the NVR inside. Of course getting physical access to it later would be a pain in the ass.

Honestly this might be a situation that calls for cams that record directly to "the cloud". These come with reliability issues of their own (they typically run on wifi) but it is a lot easier to get the video offsite this way and they can be designed to run on internal batteries of their own which greatly simplifies your setup tasks and makes them easier to hide.
