A CCTV camera can be a useful security measure, but you may want to disable it temporarily for various reasons. Here’s a step-by-step guide on how to freeze a CCTV camera.


When it comes to freezing a CCTV camera, there are a few fundamental tools you should have on hand before you get started. These include a screwdriver, a multimeter, and a tool for opening the camera enclosure. You may also need a thermal camera to detect the surface temperature, and a computer and software to access the camera. Let’s take a closer look at the tools you’ll need to freeze a CCTV camera.

Gather the necessary tools

To freeze a CCTV camera correctly, you will need some basic tools that can be found easily either around your house or in any local store. These include a screwdriver, pliers, scissors and electrical tape. Additionally, it is also important to make sure to have the appropriate type of cooling agent for the job. Typically, freeze sprays are used in this procedure as they are both compact and powerful enough to properly cool down any CCTV camera. Once you have everything ready and within reach, you can continue with the process.

Prepare the tools for use

Before freezing a CCTV camera, it is important to properly prepare the tools that will be used to do so. The materials you will need include: a can of liquid nitrogen (can be found in most auto parts stores), a heavy duty vacuum pump, an approved freezer-safe plastic bag, at least two sets of industrial grade gloves, and safety goggles. Additionally, make sure the area you are working in is cleared from any flammable materials or debris.

Before beginning, put on the safety goggles and gloves as these will help protect both yourself and the camera from harm during the procedure. Next, place the chosen camera inside the plastic bag and carefully seal it shut with a zip-tie or similar device. Once closed securely, move outside to begin work with the nitrogen and pump. Once in position, attach one end of the vacuum hose to the port of liquid nitrogen canister and then secure it to the other end of your vacuum pump line. Finally when ready, slowly open up your can of liquid nitrogen and let it settle on top of your bagged camera by holding down on all sides until fully frozen. After a few minutes have passed, carefully turn off all devices before operating your CCTV camera as normal.

Camera Location

When it comes to installing a CCTV camera, the location matters more than anything else. The camera should be placed in a strategic location such that it has full view of the area you are looking to monitor. Generally speaking, the camera should be placed in an area that has the least amount of obstacles that could obstruct the camera’s view or block the camera from capturing the footage. You must also consider the lighting conditions at the area where the camera will be installed. With the right camera location, you can get the most out of your CCTV camera.

Identify the location of the camera

In order to effectively freeze a CCTV camera, you will need to first identify where its location. As cameras are most commonly found on the outside of buildings or in other public areas, you can use binoculars or a zoom lens for your camera to get a better look at where the camera is located. Look out for any mounting hardware that the camera could be attached to, like walls, poles or lamp posts. You may also want to consider the direction which the camera might be working in and what objects are placed between it and any open area it is surveilling. Once you have identified its exact position, you should then prepare all necessary tools before moving to that location. This can help you quickly disable the unit without disrupting others in your vicinity.

Check for any obstructions

When selecting the location to freeze a CCTV camera, it is important to check for any potential obstructions. Obstructions can come in the form of physical barriers such as furniture or walls, as well as environmental elements such as light sources or people passing by. The perfect spot should be an area that is not prone to frequent interference and provides an adequate image quality.

The optimum camera angle should be determined prior to installation in order to capture maximum detail. This may require you to make certain adjustments such as zooming, panning and rotating the camera so that it has a clear field of view with minimal obstructions. Depending on the angle and amount of background activity, you may need to opt for a wider field of view so as not to miss any crucial details or moments that might unfold within your frame. Additionally, when selecting your camera placement, you must choose carefully between natural lighting or artificial lighting so that it does not interfere with your image quality.

Another factor to consider when setting up a CCTV camera is its proximity from the subject matter. The farther away the camera is placed from objects or persons being monitored, the more detailed footage will be captured; however, this depends on whether optical zoom capabilities are available for a particular model. If close-up monitoring is desired then an appropriate distance must be maintained between objects being imaged and the viewing lens of your wireless security camera system in order to collect accurate data without compromising video distortion or clarity.

Camera Disabling

Disabling a CCTV camera can be done in many ways. One of the most popular methods is to freeze a CCTV camera. This is done by jamming the electronics of the camera and preventing it from capturing images or footage. This can be done by using various tools, and it can be a very effective way to prevent your surveillance from being recorded and monitored. Let’s look at how it works.

Disconnect the power source

Disconnecting the power source is a great way to freeze a CCTV camera. This method requires you to cut off the direct access of power to the camera by locating and disconnecting its wires or power source. Once you have located the wires connected to your CCTV camera, you can turn off the circuit breaker that supplies power to it or unplug its power cord from the electrical outlet. After that, place tape over any exposed receptacles or other openings in order to prevent an accidental connection while disabling your camera. To ensure complete safety, check that all connections are well secure and taped off before continuing with disabling other parts of your CCTV system.

Cover the lens with a cloth

Freezing a CCTV camera with a cloth is a simple and effective method that can be employed quickly to disable the camera. Before beginning, you’ll need to source a dark-colored cloth or piece of clothing to cover the camera lens. Doing this prevents light from entering the lens, thus disabling it. Additionally, this method may only temporarily disable the camera so ensure that you will have enough time for it not to record your actions before you begin.

Once you have the material ready, locate the CCTV camera and place the cloth over its lens. Make sure that it fits snugly and does not move around as this could void its effectiveness in blocking out light from entering the lens. Once covered, check that no light is visible coming through any gaps around the fabric if there are any; if so, adjust as necessary until all gaps are blocked off from incoming light.

Once satisfied with your placement of material, step away or take action as required; at this point your security footage will stop being recorded until you remove the material covering your camera lens. Be aware however that motion sensors can still detect presence despite having obscured vision; this method should be used accordingly when taking into account such devices.

Remove the camera from the wall

In order to disable a CCTV camera, the first step is to remove the camera from the wall or mounting device. Depending on the type of camera, this may require a screwdriver or special tool for dismantling. Take care when removing the screws as over-tightening can cause damage to both your equipment and walls. Once all of the screws are loosened, you should be able to lift off the back plate and then detach any wiring from both the component and power source. It is important to ensure that there are no loose wires which can be hazardous should accidental contact be made with any live sources.

After completely disconnecting all wiring, detach any SD card or other storage media that is attached to the component so as not to lose any saved recordings. Finally, check that all plugs are securely unplugged and powered down before disposing of your component in an appropriate manner.


Freezing a CCTV camera can greatly reduce the chances of a security breach. If you’re considering freezing a CCTV camera, there are a few methods you can use to do this. You’ll need to first understand how the camera works, what materials you’ll need to freeze it, and which tools will be most effective for the job. Let’s get into the details of what freezing a CCTV camera entails.

Place the camera in a large container

When freezing a CCTV camera, it is important that all water vapor is completely removed. To do this, place the camera in a large container such as bin or plastic bag. Leave enough room in the container so that the frozen camera is not touching the sides of the container. Once placed in thecontainer, seal it up and then place it in an area where temperature is at least minus 18 degrees Celsius (0 degrees Fahrenheit). Ensure that once placed, the temperature remains below freezing for at least 12 hours before attempting to use the camera again. Doing this will ensure that any moisture particles are frozen and prevented from damaging your footage.

Fill the container with ice

When freezing a CCTV camera, it is important to take precautions in order to avoid any damage during the process. First, you will need an airtight container that is large enough to fit the camera and enough ice cubes to completely fill it. Make sure that you are using cubes with the least amount of additives, as these can cause damage over time. Once your container is filled with ice cubes, carefully insert the camera into the center of the container. This will ensure that all angles of the camera are exposed to a temperature low enough for it to freeze effectively. It is also possible to use water and a mix of cold and dry ice in order to lower the temperature even further if needed. Be sure not to overfill your container, as this could lead to water spilling out over your camera and freezing or damaging its components. Once everything is secure, put on your safety gloves and place the container into your freezer. Allow up to 24 hours for optimal results before taking out your frozen camera and storing it in a secure location away from direct heat or sun exposure until you are ready for use again!

Let the camera freeze for at least 24 hours

Once the camera is secured with self-tapping screws, it is important to allow the camera to freeze for at least 24 hours before attempting to activate it. This allows the environment around the camera to adjust and the internal components time to acclimatize. If the camera is activated too soon after being installed, there may be potential complications due to low temperatures or extreme humidity which may prevent activation or cause technical issues.

Moreover, it is necessary for any newly installed cameras in locations with extreme cold climates (such as an artic) to be allowed ample time for temperatures near and within the camera itself have a chance to stabilize. Once these conditions are met, then appropriate installation steps can follow as normal such as activating the system and ensuring live viewing/recording is working correctly.


If you’re looking for a way to freeze a CCTV camera, reinstalling the software might be the easiest option. This will require you to first uninstall the software from the computer, making sure to back up any data you might need. Then, you can download a newer version of the software and install it on the computer. This should help you get your CCTV camera back up and running.

Reconnect the power source

Once you have successfully frozen the CCTV camera, you will need to reconnect the power source to set it back up in its original location. Before reconnecting your power supply, always make sure that all of the cables are securely in place and that any exposed wiring has been covered with extra insulation. If there is something visibly wrong with either the power supply or the camera itself, DO NOT attempt to fix it yourself and instead seek professional help.

Once your cables are firmly secured and all other measures are taken care of, carefully plug in your power supply into an electrical outlet. Make sure that both sides of the connection are safely connected before powering on your device. Next, if possible, connect your computer to a TV or monitor using a HDMI cable so that you can see how well the freezing process turned out. Finally, turn on both devices -your computer and TV/monitor- using their respective buttons in order to start up your frozen camcorder or CCTV camera.

Reinstall the camera in its original location

Once the camera has been frozen, reinstall the camera in its original location. If the location is at a high point on a house or building, you may need to use a ladder or scaffolding to access it better.

Carefully secure all wires and fastenings that secure the camera firmly in position. Check that the screws are tight and will not loosen over time. If they do become loose, they can affect the performance of your surveillance system as well as potentially damage the camera itself.

If your camera is connected to an alarm system, it must be properly wired and tested before you begin using it again. Ensure that you remember which cables go where during re-installation of your device so that any wiring errors can be easily avoided later on. Make sure any channelling for cabling is clean and free from debris by using a soft brush such as an old paintbrush before pushing cables back into place once more. This will reduce any potential risk of damage or disconnection from movement of dirt particles inside the channeling

Test the camera to ensure it is working properly

Before you attempt to freeze the CCTV camera, you should test it to ensure it is working properly. Connect the power supply to the camera and connect the video connection to a monitor or TV. If your camera has an IP address, access its web-based software via a web browser on either a PC or laptop.

Once connected you can open the cameras interface and view live footage, take screenshots or adjust settings such as brightness and contrast. You should also adjust the focus setting if needed, as after being installed in cold temperatures your focus may become out of line. To check this point the camera firmly at an object (such as a wall) and check it is in focus on the monitor – if not press auto-focus on the cameras menu and this should then fix itself.

It is recommended when testing your CCTV cameras prior to installation that you use an analogue video connection instead of IP as this will create less strain on power cables resulting in improved results once frozen outdoors due to other components having more capacity per time slot in cold temperatures.
