Examine the wiring of a smoke detector since it has 4 wires while a camera will only have 1 or two wires. Extraordinary LED lights or a complicated layout may indicate a hidden camera. If the smoke detector sits oddly near an edge/corner or at an unusual angle it may indicate a hidden camera.
Look around it with a flashlight and look for small holes or translucent (smokey) panels. A hole pointing straight down is probably a test button - the hidden cameras usually have a hole out to the side at a ~45 degree angle. If it's a hidden camera it will be pretty easy to tell. You will see a lens in there.
Your cell phone can offer some help with hidden camera detection. You can use the flashlight to search for glinting lenses in the dark, and some apps claim to detect hidden cameras by using different technologies like Bluetooth and infrared detection to pick up on radio and other frequencies cameras emit.
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.
Low Battery: One of the most common reasons for a smoke detector blinking red is a low battery. Most smoke detectors will give a red flashing signal to remind you that the battery needs replacing.

If your detectors are battery-operated, changing the detector's batteries is the first thing to consider doing when your red light flashes. Most detectors will emit a shrill chirp or beep and a flashing light when they need a battery replacement.
Use a Flashlight / Lens Detector
Some hidden cameras are so small that they can be concealed inside a hole in an alarm clock or a computer mouse, making them easy to miss even with a careful manual inspection. A flashlight or lens detector is another practical approach to finding hidden cameras.
Mobile spyware is malware that allows hackers to steal information and watch anything within view of your phone camera. It can also enable them to access your microphone, location, calendar, and contacts. This makes it possible for hackers to record your videos and calls.
Shutting down a security camera is as easy as bringing a flashlight. A powerful LED flashlight can disable a security camera without ever requiring the crook to be on camera. Of course, this trick only works at night, when the LED light will blind the camera lens.
Spotting unfamiliar vehicles repeatedly parked or idling near your home can be a sign of robbers casing the area. Pay attention to vehicles that are out of place, especially if they contain occupants who seem to be watching or taking notes. Note the make, model, color, and license plate number.
Look at the size of the light bulb in comparison to other lighting fixtures in the space. If it is significantly larger, there's a chance it could contain a device inside it. Check for a lens on the light bulb by shining a light on it at various angles in the dark. Light will bounce off the lens.
Start at the top and search for a small lens
The easiest (and fastest) way to find out if your TV has a camera is to read the owner's manual. For many companies, like Samsung, you can go onto the company website and search for the model number of your TV and be able to download a PDF of the owner's manual.
The easiest way to tell the difference between a monitored smoke detector and a non-monitored smoke detector is that monitored smoke detectors have a red LED light.
In some cases, smoke isn't even necessary — a hint of burnt food can be enough to set off the detector. Leaving bread in the toaster or popcorn in the microwave for a little too long can send heavy particles into the air, which your smoke alarm picks up.
You may also notice your smoke alarm has a green light. This means that AC power is operating the smoke alarm, so if it goes out, it means the power has been interrupted. If this is the case, check the circuit breaker and the wiring to fix the problem.
What is the 3-digit number to see if your phone is tapped? If your phone is on a CDMA network like Verizon or US Cellular, dialing the code *72 will tell you whether any of your calls or data are being forwarded to another number. Dial *#002# to uncover this kind of phone tapping on GSM networks.
One of the simplest methods to tell if a CCTV camera is on is through a visual inspection. Look for signs like LED lights or subtle movements in the camera. Many modern cameras have indicator lights that glow or blink when the camera is active.
Dial a USSD code.
Call *#21# or *#62# and listen for information on whether or not your phone is being tapped. If calling the code does not return any information, that is a sign that your device is not being tracked.
Scan for odd details like miniature lens holes usually related to cameras. Examine the wiring of a smoke detector since it has 4 wires while a camera will only have 1 or two wires. Extraordinary LED lights or a complicated layout may indicate a hidden camera.
Turn off the lights in the room and place your mobile camera in front of the smoke detector. Look for any infrared lights that appear on the screen, as these may show the presence of a hidden camera. If you observe either white or purple lights, there is likely a hidden camera within the smoke detector.

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.
A flashing green light is a normal part of the power up cycle. Any time there is a power outage, brownout, surge or other problem with the power, the alarm goes through a power up cycle.
