    Any suggestions for a (simple, cheap, no internet) DIY alarm system?

    Posted: 07 Dec 2020 02:32 PM PST

    TLDR: I want to build an old-school home security system with 4-6 motion/door sensors and a siren. SMS notifications would be great. I don't like internet based systems. Any suggestions on what to get?

    Hello! Thank you for helping me do this research, I want to build a home security system and I'm trying to find out where to start. I'm trying to gather info as I'm a total noob but I'm planning on building my own home security system.

    The requirements that my ideal home security system should fulfil are these:

    • Minimum:
      • 1 window opening or glass breaking sensor
      • 2 motion sensors
      • Loud siren
    • Best:
      • 3 door opening sensors
      • 2-3 motion sensors
      • Loud siren
      • Alarm control unit
      • SMS notification capability + SMS remote turn on/off
      • Unauthorized tamper detection (is that a thing?)
      • Works, at least partially, when power or phone landline outrage (some battery backup)
      • Loud siren
      • Few wired elements
    • Not interested in:
      • Internet cameras, local video storage is a "nice to have" but not needed
      • Internet connected stuff, in general. I want to keep it simple & reliable.
      • Wi-Fi connected elements, really easy to tamper with (jammer, power outrage that takes down the router)
      • Monthly fees (apart from SIM card, I was thinking on getting something like IoT SIM card Things Mobile which allows basic GPRS internet and SMS). So no fancy Ring or ADT (I've read redditors in this sub are good friends with ADT salespeople)
      • Phone companion apps.

    I've seen a lot of people recommending HomeAssistant. I don't mind tinkering, I feel comfortable with raspberries and arduinos, but I think that's more complex than I need. I just want an old-school system that does not give many headaches, does not have easy access holes (i.e. no power > no Wi-Fi > no Home assistant) and deters bad guys with a loud noise.

    What are your suggestions? Do you think this are reasonable requirements? Should I hire a professional? Would you recommend any of the of-the-shelf systems? (see Honeywell alarm kit)

    About my house: There are three entrance points, two doors (main and backyard) and a double-glass window. The other windows in the house have bars/grilles. The main floor is pretty linear, with rooms distributed on the sides of a main corridor that connects the opposing entrance and backyard doors. I guess that motion detection in that corridor and/or on the entrance doors might suffice, as there is no way to move around the house avoiding that corridor. Internet and phone work though optic fibre, there is no cooper landline, and electricity and fibre cables are easy to cut from the outside, there is nothing I can do about it.

    Sorry for the long and imprecise post, anything you have to say about this is welcome

    Solar power LED security light

    Posted: 08 Dec 2020 01:14 AM PST

    I want to get a solar power security light and possibly even mount it to a pine tree in the back yard. Im not sure where to find a heavy duty enough pole thatll keep it 15-20 ft up in my area. So I figured maybe a tree? Has anyone used solar powered LED security lights successfully before? I know alot of solar powered lights are pretty bad.

    Need advice before purchasing

    Posted: 07 Dec 2020 07:44 PM PST

    I'm looking for low budget wireless security cameras to install at my great uncle/aunt (99/96yo) to make sure their home attendants don't abuse/mistreat/burglarize them.

    What I will need though is a camera that won't REQUIRE a mobile app to view the footage remotely. I want the ability to login via browser too...

    It seems like the ones on amazon are app only or sdcard based...

    Any suggestions?

    Thanx in advanced.

    New home with home ethernet for POE camera

    Posted: 07 Dec 2020 11:15 PM PST

    I recently purchased a home, and it came with 4 pre-existing POE cameras. I got the system up and running, but it looks like there are additional spare ethernet cables that comes out of the wall where the 4 POE cameras comes that are labeled similarly to the 4 POE camera ethernet cables. i.e front east, front west, back east, back west, side east, side west, front center. The problem is that only 4 of these ethernet cables leads to the 4 cameras I see outside, with the other 3 ethernet cables leading to nothing.

    I am assuming the builder got the network guy to wire the house for capability to have 7 cameras, but ended up only installing 4 cameras. The problem is, when I look around the outside of the house, there is no obvious way where I can tell where the other ethernet cables go. Does anyone have any clues as to how I can approach this without knocking down walls in the search of the other end of these Ethernet cables?

    Storage unit security / alarm / cameras ideas?

    Posted: 07 Dec 2020 03:06 PM PST

    Hello,

    My storage unit was recently broken into and some items were stolen. I am looking for ideas to make the unit more secure if possible.

    1. There is a power outlet inside, but no wifi. Thought about investing in a trail camera, but what good is a trail camera if it can just be taken?

    2. Does there exist an alarm that can go off if not disarmed within a certain time period that I can stash somewhere to at least possibly deter a thief?

    I am open to suggestions.

    Thank you.

    Door bell that uses coax?

    Posted: 07 Dec 2020 04:34 PM PST

    Hello!

    Bought a house that has a coax cable sticking out in the front beside the front door, near where the doorbell is.
    We reached out to the original builder and they said its for a security camera door bell set up but they couldn't give us any further information.

    Anyone have any ideas?

    Thanks in advance!

    Edit: there is an extra coax cable to where the ISP has run the coax for internet in the library space. The assumption is that this extra coax cable is the one connected to outside. But no other equipment.

    Which Doorbell Camera/Camera Is Best?

    Posted: 07 Dec 2020 03:50 PM PST

    Between Eufy and Amcrest; which is the best? By best I mean which one has the lowest lag time, least amount of software issues, and longest battery life. I will not be using the wired system. I can only work with the battery operated ones.

    WiFi cameras

    Posted: 07 Dec 2020 07:57 AM PST

    The house I live in now has security cameras outside but I'd like two for inside. I don't really want our roommate to have access to these cameras, seeing as I don't have access to the outdoor ones. Is there any WiFi cameras that have an additional passcode besides the WiFi. They would have to figure out what app I use for the cameras but I guess it's just piece of mind. Thx in advance:)

    Security and reliance of 433 MHz and 868 MHz alarm systems against jammers. Also, are they universally compatible?

    Posted: 07 Dec 2020 01:02 PM PST

    TLDR: How resilient are 433, 868, zigbee and z-wave systems against signal jammers? How do the alarm control units react to those attacks? Are sensors using the same protocol fully compatible regardless of their manufacturer (see Honeywell 433 MHz control unit + Aliexpress 433MHz door sensor)?

    Hello! Thank you for helping me do this research, I want to build a home security system and I'm trying to find out where to start. I'm trying to gather info as I'm a total noob but I'm planning on building my own home security system.

    I have seen different presence or door/window alarm sensors that operate wirelessly. There are different communication technologies, which include zigbee, z-wave, regular wi-fi, 433 MHz and 868 MHz bands. I've been considering 433 or 868 MHz sensors as that's how commercial solutions work, there are of-the-shelf components and I just want to build an alarm system, I'm not really interested in smart home applications.

    My concerns are:

    • How resilient are 433, 868, zigbee and z-wave against signal jammers? How common are signal jammers in these frequencies? How do the control units react to those attacks? Do they trigger the alarm? I know for a fact that it's super easy to tamper with a wifi network. Over wifi, even if the network is secured and the attacker does not have the password they can spoof your connected devices and send enough gibberish connection requests so as to make the router confused and kick out your authenticated devices from the network. I've done this myself in the past, similar to a DoS attack.
    • Are sensors using the same protocol fully compatible regardless of their manufacturer? For instance, let's say I get a Honeywell control unit + keypad. They say they are using 868 MHz band, they call it ActivLink, could I use some cheap aliexpress 868 MHz sensors connected to that unit? Do I need Honeywell-specific sensors? I've read about zigbee products that are not compatible between brands (see Philips Hue lights and Xiaomi Yee lights). Z-wave devices, being it a proprietary protocol, should work regardless of the supplier, right?
