I have setup a couple of ZOSI home systems. They are very similar to the ones shown here and similarly priced. I got mine through Amazon. In fact most of these companies use the same gear and just re-brand it. To get into the technical side of things:
DVR/NVR
This is the "base" that records everything. it will be on-site so you want it hidden/locked or you'll face the same challenge as with trail cameras (someone can take it too just so there is no evidence).
I have a 2TB hard drive in mine and the recordings go back 2 months. This is HD quality on a 4 camera system that records 24 x 7.
You need a TV with an HDMI port to see what's on it and or at a minimum to perform the setup (there are some far more technical options that remove this requirement).
The system can run without internet. But if you do that, you won't receive alerts and you can not view it remotely (which makes this an "after the fact" solution). As you noted you have limited (10GB) of internet, so if you connect that to the system, my guess is that you wouldn't go over that with alerts. But if you started doing a lot of remote viewing, you would consume more of that 10GB.
Cameras
Each camera needs a power source of some type. They sell extendable power cables that I have used. They are thin (two-wire) that is very common with a lot of small electronics. You need to know how close the nearest power outlet is compared to where you want the camera. If it's further than 8 ft, you'll probably need the extender cable too. They're cheap and come in like 20 and 30 foot extensions. I've run mine under siding, through windows (and then just closed the window on the wire), and if you really wanted you could just drill a tiny 1/8" hole if you were willing to cut off the end of the wire and re-connect it once the wire is through a wall)
You have two options for hooking them up:
- You can hard wire the cameras to your network (if you have a network). But with outbuildings and such that can get really messy. Plus I think that you mentioned not a lot of access to attic, etc.
- You don't need hard wire them. The systems come with their own WiFi for exactly that purpose. The two systems I have setup only use the built in WiFi for the cameras to connect to the base unit. The cameras also act as antennas - this is a great feature! So you can have one camera (CAM-A) 30ft away from the base unit and one camera (CAM-B) 30ft past that camera and as part of the setup you can use CAM-A to connect to CAM-B which basically extends the range out to 60ft (I hope that makes sense).
Initial Setup
It's truly plug and play.
Plug the mouse in.
Plug the DVR/NVR to your TV via an HDMI cord (you have to supply that)
Plug the DVR/NVR into a power source and follow the on screen steps.
The DVR/NVR has it's own WiFi and when you plug in the camera to a power source, it automatically connects to the DVR/NVR and displays on the TV (like - that way easy!).
Very very simple. You don't have to be technical.
Alerts, Remote Viewing and Internet
This is where things get more complex (or into an area that I'm unsure about due to your internet connection type).
You said you have some capability to use internet but it's satellite. I understand the technology but I don't know what device you have. But here's what I can tell you. The DVR/NVR that I am familiar with has 2 ways to get it connected to the internet:
- Using a home WiFi that is connected to the internet (meaning the DVR/NVR connects to your wifi wirelessly).
- Using a hard-wired solution that connects via an RJ45 Ethernet cable directly to the DVR/NVR.
I don't know what capability the device is that you have for internet has. If it is something like a mobile hot spot from a cell carrier that's easy enough to just plug that in, leave it on and during the setup, connect the DVR/NVR to the WiFi hot spot.
Generally you can configure each camera by time of day (Record Motion, Send Alerts, etc.). Typically they are all setup to do the same thing. And because the unit I'm used to setting up stores video for so long, I just let it record all day and I have it send motion alerts all day. I do not have it send emails. There is a phone app that lets me know if something alerted and it's also how I view the system remotely. typically the system is always alerting for some reason (branches, flowers blowing, birds, etc.).
Other stuff
The night viewing is great. But keep in mind, the best range to see someone's face or read a license plate is closer than you think (even during the day). As an example, I had someone go through my truck one night (I forgot to lock it). I could see someone walk up, I could see the light go on inside the cab but my camera is close to 50-60 ft away so I couldn't tell you anything about the person.
The systems are typically not expandable. So I learned this the hard way after the above incident... I wanted to add a camera or two. I emailed back-and-forth with the company and they said it can't be done. They are "hardended systems" that come pre-configured. So if you even think this is a possibility down the road, I would recommend buying an 8 camera unit and if you only put out 4 or 5 to start you still have options. The cost isn't that much more to leave 2 or 3 in a box for possible later use.
The hardest part of the whole thing was figuring out where to put the cameras. Seriously! Which way a camera points, where power is, where windows and doors are that need to be on camera took way more time to figure out. You have to do all of that before you buy so you know what you're doing for power to the cameras.
And a "pro tip" - Setup the DVR/NVR and just test a camera inside the house near the TV. Then setup the phone app. That way you can then use the phone app to adjust the camera (angle/tilt) while you're out on a ladder mounting the camera instead of running back to the TV every few minutes.
I set one up at my house and one up at my dad's house and I can monitor them both from my phone. He can monitor his (not mine - I didn't want to confuse him). They are really seemless.
