00:00Today, I'm going to show you how to set up a discreet home surveillance system for free,

00:03whether it's for your house, cabin, garage, or anywhere else you want to monitor.

00:07You'll learn how to turn an old phone sitting in a drawer into a security camera that sends

00:11motion alerts directly to the phone you currently use. A basic ringer-wise setup costs around $40

00:16per camera, plus approximately $30 per camera each year for cloud storage. Monitoring two doors

00:22could therefore cost you $80 up front and another $60 every year. This setup costs nothing with

00:27the free plan, or $35.99 per year for Alfred Camera Premium Standard in the United States

00:33following its March 2026 price change. I've had one monitoring the side door near my garage for the

00:38past eight months, and I've kept using it because the alerts arrive much faster than I expected.

00:42Grab your old phone and plug it into its original charger while you listen, because you can run the

00:46first test in about four minutes. Near the end, I'll also show you how to make a simple black cloth

00:50tunnel that dramatically improves nighttime clarity when filming through glass. That little trick

00:55can determine whether this setup actually works through your living room window. In 1966, Marie

01:00Van Britten Brown and her husband Albert filed for a patent on August 1st for a home security system

01:04utilizing television surveillance, with four peepholes, a sliding camera, and a monitor inside.

01:09She was a nurse in Queens who wanted to see who was at the door without opening it. Every video

01:13doorbell

01:13you can buy descends from that idea. Your old phone already has the two parts she had to invent,

01:18a camera and a screen, plus Wi-Fi and a motion sensor and software. The finished proof is simple.

01:22My retired Galaxy A32 sits seven feet high on my side window trim, angled slightly down at the steps.

01:29When a person crosses the mat, my current phone buzzes in about three seconds with a 12-second clip,

01:34like an open live view. Listen and speak back through the old phone speaker. Total hardware cost was

01:39zero for the phones, plus $11 for parts I will list. Compare that to $80 for two Wyze Cam V3

01:45units at

01:46about $40 each, plus $60 per year for two Camplus licenses. Over three years, the store route is

01:52$260. The phone route is $0 on the free plan, or $107.97, over three years on premium at $35

02:00.99 per year.

02:01You keep $152 to $260. Then you reuse a device that was losing value in a drawer. Pick your app.

02:07Before you reset anything, because local versus cloud decides your storage and your privacy,

02:11Alfred Camera is the easiest reputable choice for this exact job, and it runs on iPhone and Android.

02:17The free tier gives live view, motion alerts, and short cloud clips with ads and a lower retention

02:21window. Premium standard at $35.99 per year in the United States removes ads, extends cloud history,

02:28and adds higher quality recording. Local means clips. Stay on the old phone, or your network cloud

02:32means clips upload so you can see them if the old phone is stolen. For a door camera, choose cloud

02:36clips

02:37for theft protection. For an indoor pet camera, choose local only. Download Alfred Camera on both

02:41phones from the App Store or Google Play Store. Made by Alfred Systems, check the developer name,

02:46and the 50 million plus downloads so you do not install a clone. A lot of advice about this build

02:50is wrong, and it causes most failures. The first myth is an old phone camera is too blurry to identify

02:56anyone. At 8 to 12 feet in daylight, an 8 year old 12 megapixel sensor resolves a face, a jacket

03:01logo,

03:02and a package label because the subject is close and still for two seconds. Blur comes from dirty

03:06lenses, digital zoom, and shooting through double pane glass at an angle. Not age. The second myth

03:11is you need a SIM card and a cell plan. You do not. Wi-Fi alone carries alerts, live view,

03:16and cloud

03:16clips. Remove the SIM if you want. It lowers heat and stops carrier updates. The third myth is leaving

03:21it plugged in 24 hours a day will swell the battery in a month. Constant 100% charge plus heat

03:26swells

03:27batteries. Constant power alone does not. Limit charge to 80% in settings on Samsung and Pixel. Remove the

03:32case and use a low 5 watt brick and the phone stays lukewarm. The fourth myth is free cloud

03:36viewing means no one else can access it. Any cloud account can be accessed if you reuse a password and

03:41leave two-factor off. Use a unique password, turn on two-factor, and set a four-digit viewer pin inside

03:46Alfred Camera. Reset, update, and secure that old phone like it guards cash because it watches your house.

03:52Factory reset it to wipe old banking apps and photos. Connect to your home, 2.4 GHz Wi-Fi. Not

03:57guessed,

03:57because 2.4 reaches the porch better through walls than 5 GHz. Update iOS or Android to the latest

04:04version it supports, then update Alfred Camera. Sign in with a fresh Google or Apple login you use

04:09only for cameras. On both phones, grant camera, microphone, and notifications. Deny location,

04:14contacts, and photos. Turn on two-factor for the Alfred account. Give the old phone the role of camera

04:18and your daily phone the role of viewer. Test the link by waving in front of the old phone. You

04:23should

04:23get an alert on the viewer in two to five seconds. If alerts lag past 10 seconds, disable battery

04:27optimization for Alfred Camera, so Android does not put it to sleep. Continuous power without

04:32overheating is the difference between a camera that lasts two years and one that quits in August. Use

04:37the original 5-watt Apple brick or Samsung 5-watt brick. Not a 25-watt fast charger. Fast chargers cycle

04:43heat up and down. Add a 15-foot flat white USB cable from Amazon Basics or Anker. About $8.99

04:50to $10.99

04:51for a 2-pack so you can root a long trim without an extension cord. Take any thick case off.

04:55Heat

04:55kills batteries faster than charge cycles. On Samsung, go to battery settings and turn on

04:59protect battery to cap at 85%. On Pixel, go to adaptive charging. On iPhone, turn on optimized

05:05charge limit at 80%. Set screen brightness to minimum and set screen timeout to 10 seconds

05:09because the display is a heater. Plug into a Casa or Topo smart plug about $10 to $13 for a

05:15single or $24

05:16for a 4-pack at Home Depot, Lowe's, or Amazon and set a schedule to cut power from 2am to

05:224am.

05:23That nightly cooldown extends battery health. Touch the back after 24 hours. Lukewarm is perfect. Hot

05:27to the touch means change the brick, move it out of sun, or add ventilation. Mounting decides whether

05:32you catch faces or tops of heads. Faces live between 4 and 6 feet high. Packages live 0 to 3

05:38feet. Mount

05:39the lens at 7 to 8 feet. Tilt down 15 to 20 degrees and you get both. Do not lay

05:43the phone flat on a shelf

05:44looking level. You will film the street and miss the mat. For vinyl window trim, you must use a Ulanzi

05:50ST02S phone tripod mount about $9.95 on Amazon. Screwed to a small command strip caddy so you remove

05:57it without holes. For glass use, an APPS2 car suction phone holder about $12.99. Press to the

06:04inside pane. For siding, use a cheap mini tripod from Dollarama or Dollar Tree at $5 weighted with

06:10a sock of rice. Wipe the lens with a microfiber cloth, the kind that comes with glasses. Set feel

06:14the view so the mat fills the bottom third, the door handle sits mid-frame, and the steps fill

06:18the top third. Walk the path yourself with a hat on and a box in your hands. If you can

06:22read the

06:22shipping label at 6 feet on playback, the angle is correct. If you like fixes that use what you

06:27already own, hit subscribe because that is what I build here and members get early access to extra

06:32how-to videos and the parts lists I only post for members. I keep a running file of mounts and

06:37cable

06:37links for rentals and houses so you do not drill where you should not. Motion zones, alerts, and storage are

06:43where

06:43cheap cameras annoy people into unplugging them. Open Alfred camera on the viewer. Open the camera

06:47settings and draw the motion zone tight around the mat in two steps. Exclude the sidewalk and the road.

06:52A zone that includes passing cars will send 80 alerts a day and you will mute it and miss the

06:57thief.

06:57Set sensitivity to medium to start. Set a three minute cooldown between alerts so one lingering

07:03courier does not send nine clips. Turn on person only if your plan includes it. Leave all motion on for

07:07the first three days while you tune. On free, clips live in cloud for seven days. On premium standard,

07:12they keep longer and you can download without ads. Once a week, download any keeper clip to your

07:16viewer phone. Once a month, open the old phone and delete local cache so storage never fills.

07:21Run the proof test at noon. Have someone approach with a parcel. Knock. Leave. You should have one alert,

07:25one 10 to 15 second clip, and a thumbnail with a readable face. If you get zero alerts,

07:30raise sensitivity one notch. If you get five alerts for one visit, shrink the zone. 5% and lengthen cooldown.

07:35Night limits and false alarms kill more DIY cameras than bad wifi. A phone sensor is tiny,

07:41about one third inch, so it needs light. Through glass, the old phone sees its own infrared reflection.

07:46The night mode turns milky white. Do not aim through closed blinds at night and expect faces.

07:51The fix that actually works is light plus distance. Screw a 9 watt 800 lumen warm LED porch bulb into

07:57the

07:57existing socket. About $6 for a two pack off at Home Depot Canada, Lowe's, or Walmart. Light the person,

08:03not the camera. Then build the black cloth tunnel I promised. Drape a black microfiber towel over the

08:07top of the phone and the glass behind it, forming a three-sided hood that blocks ceiling reflections.

08:12That single hood took my window night clips from white glare to a visible jacket and hat. Expect 10

08:17to 15 feet of useful night detail with a porch light. About 30 feet like a dedicated Wyze Cam V4

08:23with

08:23stacked infrared. Moths, rain, and shadows cause false alarms because pixel motion detection watches brightness

08:29change, not shapes. Lower sensitivity one notch after sunset if your app allows schedules,

08:34or narrow the zone to the mat only at night. In winter, keep the old phone inside the glass,

08:39not outside. Lithium batteries shut down below minus 10 celsius, and touch screens crack and freeze thaw.

08:44Privacy and law matter more here than with the store camera because you built it yourself.

08:48Do this privacy test before you trust it. Open live view on your viewer, cover the old phone lens,

08:53and confirm the image goes black. Speak from the viewer and confirm you hear it at the door.

08:57Then check sharing. In offered camera, open trust circle and confirm only your viewer account has

09:02access. Turn off audio recording if your state or province requires all party consent for audio.

09:07Video of your own porch is broadly allowed in the United States and Canada. Audio is stricter.

09:13Illinois, California, Florida, Pennsylvania, Washington, and several other states. Limit recording of private

09:18conversations without consent. In Canada, recording a conversation you're a part of is generally

09:23allowed, but recording neighbors' audio across the fence is not. Point at your steps and your mat,

09:29not a bedroom window or a neighbor deck. Put a small $3 video recording in progress sticker on the

09:35door at eye level from Amazon or a hardware store. It deters and it documents notice. Never place this in

09:41a

09:42bathroom or rental bedroom or pointed at a shared hallway without written permission. We're to buy this

09:46without overthinking. You already own the two most expensive parts. The phones? On Amazon, buy the

09:52Ulanzi phone mount for $9.95, the Anker 15-foot USB-A to Lightning or USB-C cable for $10

09:59.99, and a

10:01Toppo or Kasa smart plug for $11.99. At Home Depot, Lowe's Canadian Tire, or Bunnings, buy a 5-watt

10:10brick if you

10:10lost the original, about $8.00, and a 2-pack of 9-watt warm LEDs for about $6.00. A

10:17pre-made equivalent

10:18is a Wyze Cam V3 at about $39.98, plus a 15-foot outdoor cable at $12.99 plus cam,

10:26plus at $29.99

10:28per camera per year. One door store built is about $53 year one. One door phone built is about $22

10:35in

10:36amounts, and cables year one and $0 per year after if you stay free. Two doors doubles both. The phone

10:42build wins by $62 in year one and by $122 by year two, with no new e-waste. Three small

10:49tricks lift

10:49this from working to reliable. Put a white index card on the mat with your house number in the thick

10:54marker for the first week. Playback will prove whether numbers read at night. Wrap one rubber

10:59band around the phone and mount as a vibration damper on vinyl siding. Windshake causes half of daytime

11:04false alerts. Name the camera Side Door, 7 feet in the app. Not Camera One, because a clear name

11:10makes clips searchable when you need one. Fast for a parcel claim. Do your final walk test at dusk

11:15with the porch light on. Approach like a courier and look at the door for two seconds. Set down a

11:19box,

11:20leave. Open the clip. You want a lit face, a readable motion thumbnail, and one alert. Not four. If the

11:26image blooms white, move the phone one inch closer to the glass and reseat the cloth hood. If audio

11:32echoes, lower viewer volume one notch. And disable speaker on the old phone for door only use.

11:37If this saves you $200 and keeps a good phone out of landfill, share it with someone still

11:42paying monthly for cameras. See you in the next one.
