Smoke detectors are highly common security devices in most commercial spaces such as offices and residential homes. Since they are so common, most of us tend to ignore the smoke detectors when we spot them. Chances are, there might be a hidden camera in them. This is because it is super easy to hide cameras in them!
After locating the smoke detectors that are candidates for a camera, visually inspect the smoke detector and look for a small black dot and pinhole openings that provide the lens with perspective and a visual window. Like any camera lens, it will reflect and have a distinct visual appearance.
Turn off the lights and look around. Infrared cameras will give off a red light. Use a flashlight or the light on your smartphone and slowly look around bedrooms and bathrooms. Hidden cameras will have a lens and you may be able to see a glare from the light.
Yes, your cell phone can detect a hidden camera. All you need to do is download a hidden camera detector app. Once you have the app installed, simply open it and scan the area for any hidden cameras.

Your alarm manufacturer may have included a blinking red light to let you know it's time to test the alarm again. The Batteries are Low: Usually accompanied by a loud beep, a blinking red light could mean the batteries in the unit are low. Consider adding fresh batteries and running a test to make sure it's working.
For most residential smoke detectors, blinks are common; you need to be conversant with the colors showing. Different smoke alarms use the green and red LED to indicate the device's power status such that a flashing green means low battery while a constant blink means AC power is connected.
Turn off the lights and draw the curtains (the room must be dark), turn on both the flashlight and phone camera, and point them where you think a hidden device might be lurking. If your suspicions are correct, you will see a glare on the smartphone screen.
No. Despite the name “Internet Protocol,” IP security cameras do not require an outside connection to the Internet. All that's required is a connection to your local area network.
Some hidden cameras emit IR (infrared radiation) light, which isn't visible to the naked eye. The camera lens on your Android phone will pick up infrared light if you hold your device close enough. If you find a hidden camera that emits IR, it will appear in your camera's display as bright blue-white light.
BLUE/CO: Blue light flashes rapidly when sensor detects elevated CO levels.
This battery characteristic can cause a smoke alarm to enter the low battery chirp mode when air temperatures drop. Most homes are the coolest between 2 a.m. and 6 a.m. That's why the alarm may sound a low-battery chirp in the middle of the night, and then stop when the home warms up a few degrees.
The most likely reason smoke detectors go off unexpectedly is that people aren't changing the batteries in them often enough. In most sensors you might think of, the strength of the signal goes up when they detect what they're supposed to. Common causes of smoke detector false positives around the house.
If your detector or alarm has a blinking or steady light with no audible alarm sound, this typically indicates that the unit is receiving power.
The "HUSH" feature has the capability to temporarily desensitize the smoke alarm circuit for approximately 7 minutes. This feature is to be used only when a known alarm condition, such as smoke from cooking, activates the alarm. The smoke alarm is desensitized by pushing the "HUSH" button on the smoke alarm cover.
3 chirps (about 1x per minute): Malfunction chirp
Replace with a new alarm as soon as possible. Check to ensure that your alarm is not expired and in need of replacement.
Power interruptions are common in areas where utility companies switch grids in the early hours of the morning. In AC or AC/DC smoke alarms, a loose hot wire connection can also disconnect power to the smoke alarm. The effect is the same as a power failure. When power is restored, the units may alarm briefly.
Smoke alarms detect fires by sensing small particles in the air using a couple of different kinds of technologies. Once they detect those particles above a certain threshold, they signal the alarm to sound so that you and your family can get to safety and call 911. Smoke alarms save lives.
First, your home security company is instantly notified when the alarm is triggered and will immediately be contacting you to assess the situation. They will also notify the authorities. Second, you can call someone outside of your home in order to get help.
It's time to change the battery
Low batteries are the most common reason smoke detectors beep or send a trouble signal to your security panel, when there is no smoke or fire. As the battery weakens, the device will beep regularly to let you know it's time to replace it.
Most battery powered smoke detectors will beep for a minimum of 30 days before the battery dies. You'll know the battery is losing charge if you hear consistent beeping every 30 to 60 seconds.
The smoke alarm is desensitized by pushing the Test/Hush button on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately and the red LED blinks every 10 seconds. This indicates that the alarm is in a temporarily desensitized condition.
Hidden Camera Blocking
Tape, spackle or caulk over any drill holes containing hidden listening devices. If you get lucky and find a wired power source for a hidden recording gadget, simply unplugging it may be enough to stop it from recording.
