Video surveillance · Metro Atlanta Commercial security camera installation in Metro Atlanta
LIT Inc. designs, installs and services IP camera systems for commercial buildings across Metro Atlanta. Every camera is placed for what it needs to see, and every system keeps footage long enough that it's there when you need it.

01What we install
Video surveillance planned before it's priced
A camera on the roofline can tell you a car pulled into the lot. It usually can't tell you the plate number or who got out. That gap is a design problem, and it should be solved before install, not discovered after an incident.
We start with a site survey. We walk the property with you, decide what each camera has to capture and design the system around it. Then we price the job from that design, install and test it, and stay on to service it.
What we install
- Indoor and outdoor IP cameras, with the type and lens chosen for each location
- On-site recording, sized to the number of days you need
- Live and recorded video on your phone or computer
- Camera views tied to access control events
- Service, repair and upgrades for existing camera systems
02Coverage
Coverage planning: see it, recognize it, identify it
Megapixels don't tell you whether a camera will do its job. Pixel density does: how many pixels land on a person or a plate at the distance they'll be. Guidance based on the IEC 62676-4 standard puts face identification at about 80 pixels per foot and recognizing a known person at about 40. Spotting that someone crossed a lot takes far less.
We use those targets to place every camera. Doors, registers and gates get close views with enough detail to identify. Lots, yards and long aisles get wide views that show movement and direction. If a spot needs both, it gets two cameras instead of one stretched too far.

- 40px/ftto recognize a known person

03Recording
Recording, retention and remote viewing
Every system starts with one number: how many days of footage you need to keep. Many businesses keep 30 to 90 days, and some industries and insurers set their own minimums. Storage is sized from that number, the camera count, resolution, frame rate and whether cameras record continuously or on motion. Newer compression such as H.265 can cut storage by roughly 40 to 50 percent compared with H.264.
Footage is recorded in the building, on a network video recorder (NVR) or a server running video management software (VMS), so recording keeps working if the internet goes down. We size the recorder for your retention target and install it where it is secured, so it is hard to tamper with or carry off.
Whichever you choose, authorized staff can watch live video, search recordings by camera and time, and export a clip for police or your insurance carrier.
04Network
The network behind the cameras
IP cameras are network devices. Most draw power and send video over a single Cat 6 cable using Power over Ethernet (PoE), so there's no separate power run to each camera. A standard copper run is good for about 328 feet. Farther points, like a back gate or a light pole in a yard, use fiber or an extender.
We also install network cabling, so the camera system is designed with your network instead of added on later. That matters for security as much as for picture quality.
On the network
- Cameras on their own network segment (VLAN), separate from office computers
- Default passwords replaced, with a separate login for each user
- Firmware updated at install and kept current on service visits
- NDAA Section 889 compliant cameras and recorders when the project calls for them
05Upgrades
Upgrading or taking over an existing system
Plenty of buildings still run analog cameras on coax to an old DVR. When it's time to upgrade, we replace them with IP cameras on new network cable. You don't have to do it all at once: we can phase the work so the most important views are replaced first.
We also service and repair most camera systems we didn't install. If your last vendor is gone or the recorder has stopped recording, call us. We'll find out what's there, what still works and what's worth keeping.
06Facilities
Cameras for your type of facility
Video is usually one part of a larger job. We plan it with access control, intrusion, fire alarm and cabling, so cameras land where the doors, gates and alarm points are. Paired with access control, every badge read and forced door has footage behind it.
Based in Dallas, GA, we install and service commercial cameras across Metro Atlanta, including Paulding, Cobb, Douglas, Bartow, Cherokee, Fulton, Carroll and Polk counties and the City of Atlanta.

FAQ
Frequently asked questions
Don't see your question? Call us at (678) 619-3548, or request a site survey and ask us in person.
Request a site surveyHow many days of video should we keep?
It depends on your business and your insurer, but many commercial sites keep 30 to 90 days. Some industries, such as banking, have their own rules. We size storage from your retention target, camera count, resolution and recording mode, so the system actually holds the number of days you asked for.
What camera resolution do we need?
Megapixels alone don't answer it. To identify a face, plan for about 80 pixels per foot on the target; to recognize a known person, about 40. A 4K camera covering a whole parking lot can still fall short, while a lower-resolution camera close to a door may do fine. We plan each view for the detail it needs.
Can we keep our existing analog cameras?
We'll look at what's there first. Analog cameras on coax are usually replaced with IP cameras on new network cable, which is where today's image quality and features are. We can phase the upgrade so the most important views come first, and we'll tell you if any of your existing equipment is worth keeping.
Can we watch the cameras from our phones?
Yes. Live and recorded video can be viewed from a phone app or a computer, with access set for each user.
Will the cameras see at night?
Outdoor cameras with built-in infrared can see in the dark, and low-light sensors hold a color picture longer as light fades. Infrared views are black and white, and faces and plates read best with some site lighting. We note where more light would help during the site survey.
Do you service camera systems you didn't install?
Yes, in most cases. We troubleshoot, repair and expand existing systems, and we'll tell you honestly whether an older system is worth keeping or due for replacement. Call (678) 619-3548 with the make and age of your recorder and cameras.
Are your cameras NDAA compliant?
We can specify cameras and recorders that comply with Section 889 of the National Defense Authorization Act, which bars Hikvision, Dahua and Hytera equipment on federal contracts and federally funded projects. Many private owners now ask for compliant hardware too.
Adding cameras or upgrading an old system?
Request a site survey. We'll walk the property with you, map what each camera needs to see and price the job from that design. General contractors can send plans for a low-voltage bid, or call (678) 619-3548.
