HELPFUL SETUP TIPS
LEARN YOUR CAMERA AT HOME FIRST
We highly recommend that you first spend some time indoors with this manual and your camera to familiarize yourself with the Settings Menu and various functions like Video capture, as well as read the tips to help you mount it properly on a tree (see Mounting & Positioning).
INSTALLING BATTERIES
To load or remove batteries, locate the Battery Release Button. Press the button and the battery tray will release from the bottom of the camera. The battery tray will stop about ½ inch out of the device, this is a latch system to prevent the tray from dropping onto the ground. Just apply a little pressure when pulling and the tray will release. The battery tray has six battery slots. Install a full set of 6 batteries. Be sure to insert each battery with correct polarity (negative or “flat” end against the long spring of each battery slot).
USING SD CARDS
Choosing A Card
Your camera requires a standard SD (Secure Digital) memory card to save photos (.jpg format) and/or videos (.mp4 format). It supports SD and SDHC (High Capacity) cards up to a maximum 512GB capacity. We recommend high speed SD cards (SanDisk® SDHC rated class 6 or higher) if you are using the 1280×720 or 1920×1080 video settings.
Before Inserting
Make sure that the write-protect switch on the side of the card is “Off” (not in the “Lock” position).
Inserting
Insert the SD card into the card slot with its label side facing the front of the camera. A “click” sound indicates that the card is installed successfully. If the wrong side of the card is facing up, you will not be able to insert it.
Formatting
To assure the card is formatted to save images and video correctly, format the SD card by using the “Format” option.
Use this option especially when a card has been used in other devices.
Removing
To remove the SD card, be sure the camera’s power is switched OFF, then gently push the card in and release it (do not try to pull it out without pushing in first). The card is released from the slot and ready to be removed when you hear the click.
CAMERA VIEWSCREEN
Check your viewscreen for the area your camera will see. Note: maximum distance of your camera is listed in Technical Specifications under Illumination Mode or on the box.
MOUNTING & POSITIONING
After you’ve set up the camera’s settings to your preferences, you’re ready start capturing images.
We recommend mounting the camera on a sturdy tree or post with a diameter of about 6 in. To get the optimal picture quality, the camera should be about 16-17 ft. away from the place to be monitored, with the camera placed at a height of 3.5-5 ft. Also, keep in mind that you will get the best results at night when the subject is within the ideal flash range, no farther than 80’ and no closer than 10’ from the camera.
The height away from the ground for placing the device should vary with the animal size appropriately. In general, 3 to 6 feet is preferred. You can avoid potential false triggers due to temperature and motion disturbances in front of the camera by not aiming it at a heat source or nearby tree branches or brush (especially on windy days).
There are two ways to mount the camera:
- Using the provided adjustable belt: Push one end of the belt through the two slots on the back of the trail camera. Thread the end of the strap through the buckle. Fasten the belt securely around the tree trunk by pulling the end of the strap firmly so there is no slack left.

- Using the tripod socket: The camera is equipped with a socket at the back (below the strap brackets) to enable mounting on a tripod or other camera mounting accessories that have a standard 1/4”-20 thread.

USING A SOLAR PANEL ACCESSORY
You can connect an optional Solar Panel accessory (model# 119986C) – please visit www.bushnell.com for more information) to the “DC In” jack on the bottom of your camera.
Other external power supplies should not be used, as the camera and/or display may not function correctly. If the solar panel is connected and AA batteries are installed, the camera will be powered by the solar panel’s rechargeable lith-ion battery, as long as it provides adequate voltage (if not, the camera will switch to battery power). The solar panel’s battery will power the camera at night.

TROUBLESHOOTING TIPS
Camera won’t power on.
Possible Cause
Batteries not fully installed, or not installed correctly.
Recommended Solution(s)
- Install new AA alkaline or Bushnell recommended Energizer® Lithium AA batteries.
- Make sure the positive (+) and negative (–) poles are lined up properly in each compartment, with (–) pole making contact with the spring.
Camera takes images without animals.
Possible Cause
A “false trigger” caused by motion (branches, water, etc.) and/or high heat in front of the camera lens when there is no subject in the image.
Recommended Solution(s)
- Move camera to spot without branches or water close to camera.
- Change sensor level in menu settings.
- Move camera to inside area without movement to check and see if it still takes pictures without movement. Contact customer service for possible repair or replacement.
Camera responds slowly to movement, does not always capture an image when triggered.
Possible Cause
PIR sensitivity setting needs to be adjusted.
Recommended Solution(s)
Go to “Sensor Level” in the Setting Menu and increase the PIR sensitivity.
Battery life is shorter than expected.
Possible Cause
Battery life will vary with operating temperature and the number of images taken over time. Setting the Interval time to 0.5 second will decrease battery life. Typically, you will be able to capture several thousand images before the batteries die.
Recommended Solution(s)
- Make sure you install all new alkaline or Bushnell-recommended Energizer® Lithium AA batteries.
- Use Bushnell-recommended SanDisk® brand SD Cards.
- Longer delays and shorter night illumination will increase battery life (you’ll take less images and use less flash). Adjust these in the Settings Menu.
camera stops taking images or won’t take images.
Possible Cause
The SD Card is full, in the locked position, improperly formatted, or the batteries are dead.
Recommended Solution(s)
- Check SD card. If full, download images, erase from card, reinstall empty card in camera.
- Move the “write protect” switch to the unlocked position.
- Reformat the card by using the “FORMAT” option in the Settings Menu.
Night images or videos look too dark.
Possible Cause
Batteries are low or Settings are not set for good night quality.

- Check battery power. If low, replace.
- Check distance of subject from camera. If beyond 80’, subject may not be in flash range.
- Go to Setting Menu, make sure Illumination Mode is set to “Long Range”.
Note: When the Capture Number is set higher than “1”, or with very short Interval settings, some images may appear darker than others due to the quick response and rapid retriggering of the camera.
Night images or videos look too bright.
Possible Cause
The subject is coming too close to camera for settings.
Recommended Solution(s)
If animals are coming within 10’ of camera, go to Settings Menu, select Illumination Mode and go to “Low” or “Fast Motion”.
Daytime images or videos look too dark.
Possible Cause
The camera is aimed at sun or extremely bright sources during day.
Recommended Solution(s)

FAQS
China.
Night Range- High contrast nighttime images with no washout. Weatherproof and Rugged– Built to withstand the heat, cold, teeth, and claws that Mother Nature throws at it.
The Field Scan “Interval” setting lets you control how often a photo or video clip is recorded during the block(s) of time you defined with the Start and Stop settings. Your options are 60 minutes, 30 minutes, 15 minutes, 5 minutes (this is the default), or 1 minute (still photo mode only).
Bushnell Core DS No Glow Trail Camera is equipped with the latest DS technology for best-quality images day and night. It has an 80-foot night range for high-contrast night photos without washout. Its rugged and weatherproof design can withstand extreme and changing weather and outdoor elements.
On top of designing and building our cameras to last, we quality control every single camera we sell in our Ohio headquarters.
“Black flash” or true No Glo cameras have the lowest possible visible spectrum of light for both humans and deer, essentially resulting in no flash. As you can imagine, this makes it the perfect camera for security, or not spooking does and mature bucks.
Deer cannot see infrared light well, making them significantly less likely to be spooked by infrared trail cameras than white flash
Howell says that red-glow cams rarely spook deer when positioned properly. For most deer hunters, these are your go-to cams.
Check to make sure the batteries are in the camera properly. If they are, replace the batteries (or test them with a ZTS Battery Tester if you have one) with new batteries.
Bushnell Trophy Cam HD Essential Review
The Bushnell Trophy Cam HD Essential is a bare-bones trail camera. This is their base model for this year and while it doesn’t have the speed and features of the new Aggressors, it should still pack some quality for the price.
Game cameras and trail cameras are different names for the same thing: a camera operated by batteries that captures images with lightning-fast speed. Setup for these cameras is quick and easy.
Yes, they do. Actually, all trail cameras have the ability or potential to spook mature bucks!
THE BOTTOM LINe
All trail cameras have the ability to negatively impact deer movement and spook individual deer.
This means that deer have the ability to see blues and even ultraviolet (UV) light, but are also sensitive to white and yellow light as well. So, the most ideal light colors for deer hunting include red, green, and orange as deer see these colors as grey and are less startled by them.
While there’s no set height, and you may occasionally need to get lower to avoid limbs, it’s usually best to keep cameras at a deer’s height — about 3 feet tall. If you feel deer will be alarmed by the camera’s presence, you can place them 6 to 7 feet higher and out of their line of sight.
Throwing a mineral site in the middle of the woods can help you get lucky, but bucks are in bachelor groups at this time of year and could be a few miles away from where they are during the fall. Placing them near water sources and food sources such as newer logging cuts will help make them more effective.
Timing is everything when it comes to properly check cameras. The location of the camera will determine the time of day or night you should check them. Morning and evening are going to be the worst times to check cameras. Wait till mid-morning to mid-afternoon when the majority of deer will be bedded up.
